3 1. INTRODUCTION Under the Work Health and Safety (National Uniform Legislation) Regulations a written asbestos management plan is prepared for a workplace where asbestos or asbestos containing material has been identified. Asbestos containing material (ACM) has been identified within the buildings and throughout the grounds of the George Brown Darwin Botanic Gardens. In line with the regulations this management plan details: control measures and safe work procedures to be followed the identification of asbestos procedures for incidents or emergencies involving asbestos or asbestos containing material at the workplace information about asbestos related work 2. SCOPE AND LIMITATIONS This management plan has been produced for the George Brown Darwin Botanic Gardens to manage and minimise asbestos related health risks to personnel working or visiting the site. The Park is located at Lot 6524 Gardens Road, The Gardens. The areas covered under this AMP include all buildings, structures and grounds at the site managed by the Parks and Wildlife Commission of the NT SITE PLAN George Brown Darwin Botanic Gardens Asbestos Management Plan Page of 37

4 3. DEFINITIONS Within the context of this management plan the following definitions apply: Asbestos Containing Material (ACM): any material, object, product or debris that contains asbestos. Asbestos Register Control Log: the asbestos control log forms part of the controlled asbestos register document and is used to record changes to asbestos in the workplace. Asbestos Register: the register used to record the presence (or assumed presence) and removal of ACM. Asbestos Related Work: work that involves asbestos and there is a potential risk of exposure to airborne asbestos fibres Asbestos Waste: all removed ACM and disposable items used during the asbestos related work, such as plastic sheeting used to cover surfaces in the asbestos work area, disposable coveralls, disposable respirators, rags used for cleaning Bonded ACM: ACM containing a bonding compound reinforced with asbestos fibres. It includes waste and byproducts such as debris and residue. Bonded ACM is typically a dense base material (e.g. cement, vinyl) to which asbestos fibres were added, usually as a reinforcing agent. Competent Person: a person with appropriate training, experience or qualifications to undertake the required task. Unless otherwise identified in this AMP a competent person may be: o o o o o an occupational hygienist with asbestos experience licensed asbestos assessors asbestos removal supervisors individuals who have a statement of attainment in the unit competency for asbestos assessors person working for an organization accredited by NATA under AS/NZS ISO/IEC 17020:2000 General criteria for the operation of various types of bodies performing inspection for surveying asbestos. Emu-bob: removal of ACM debris from surface of the ground by traversing site and picking up all visible material assumed to contain asbestos. Friable ACM:ACM that, when dry, is or may be crumbled, pulverised or reduced to powder by hand pressure. Examples of friable materials include sprayed fireproofing on structural steelwork, thermal insulation on mechanical systems and acoustic or decorative finishes on walls and ceilings. These asbestos-containing materials can present a significant degree of risk to workers and building occupants when maintenance or renovation work is performed that will disturb them and appropriate precautions are not taken. 4.

8 7. IDENTIFICATION OF ASBESTOS HAZARDS 7.1. ASBESTOS REGISTER PWCNT has engaged a qualified asbestos assessor to undertake an asbestos survey of the George Brown Darwin Botanic Gardens. Details of ACM identified through the survey are provided in an asbestos register for the site.the asbestos register contains details about the location, type, form, and condition of the ACM identified. A master copy of the asbestos register is located and maintained in TRIM by PWCNT s Asbestos Management Coordinator. A hard copy of the register is located on site at the Visitor Centre where the integrity and security of the register can be controlled. The register is also available on request through PWCNT s Technical Services Division. The asbestos register is kept up to date by the Asbestos Management Coordinator. An asbestos control log detailing ACM related work and incidents affecting the condition or presence of ACM on site is attached to the register and forms part of the controlled register document. Asbestos registers will be reviewed and revised as necessary by a licensed asbestos assessor at least once every five years. The asbestos register is available for viewing by workers and their health and safety representatives, and to anyone responsible for carrying out work or requiring work to be carried out at the workplace. A copy of the register is to be given to persons carrying out asbestos related work which involves a risk of exposure to airborne asbestos WARNING SIGNS AND LABELS All areas of the workplace, including plant, equipment and building components that contain ACM are, where practicable, labelled with cautionary warning signs to ensure that the asbestos is not knowingly disturbed without correct precautions being taken. Where labels are not practical warning signs will be installed to entrances to the areas where asbestos is present. Examples of labels and signs used to identify asbestos containing materials in buildings, plant, and equipment are shown below: Sign used to identify areas where there is a potential risk from identified ACM and access is restricted to authorised personnel only with appropriate training or where new instances of suspected ACM are found and a risk assessment by a competent person is required prior to access. Example of a sign used to warn the general publicnot to disturb debris on the ground that may contain asbestos. George Brown Darwin Botanic Gardens Asbestos Management Plan Page of 37

9 8. RISK ASSESSMENT Asbestos hazards represent a health risk when the asbestos fibres are airborne and subsequently inhaled. The risk to health increases as the level of exposure increases. Asbestos that is in a stable matrix, or is effectively encapsulated or sealed, and remains in a sound condition and undisturbed, represents a negligible asbestos health risk. The health risks posed by ACM are subject to a number of risk factors, including: Friability of the material; Condition of the material; Accessibility of the material; Airborne potential due to location of material; and Exposure potential due to location of material. The regulator advises that if asbestos or ACM is in good condition and left undisturbed, it is unlikely that airborne asbestos will be released into the air and the risk to health is extremely low. When assessing the risk to health from identified asbestos the following factors are considered: the condition and type of asbestos the likelihood for damage or deterioration likelihood of disturbance due to work practices the location/proximity to workers A risk assessment on identified asbestos is conducted by a competent person. The risk assessment guides decisions made on appropriate control measures. 9. CONTROL MEASURES To manage the risk of ACM at PWCNT workplaces a combination of the following control measures have been adopted: access restrictions removal of ACM on-site management of ACM standard operating procedures and safe work practices air monitoring 9.1. ACCESS RESTRICTIONS Access to all friable ACM is to be restricted to maintenance personnel with appropriate PPCE until such time as the material is removed, enclosed or sealed. Access to non-friable but damaged ACM is to be limited to authorised personnel only until such time as control measures are implemented that reduce the risk of airborne asbestos fibres being released from the material. Only persons who have asbestos awareness training or are accompanied by a person with asbestos awareness training are authorised to enter areas where access is limited REMOVAL OF ACM Removal is considered the preferred method of control as it eliminates the hazard from the workplace. Removal however does present a risk and involves significant resources to remove and manage at authorised disposal sites. With limited annual funding available for the management of ACM, removal will be prioritised for ACM that, as determined by a competent person, presents an immediate or high risk of exposure. Funding will then be allocated for ACM removal that: must be removed to enable the completion of scheduled works projects; or, impacts on the delivery of park services. As required under the regulations asbestos removal will be carried out by appropriately qualified persons, including: Asbestos Removal Contractors with a Class A license for the removal of all friable ACM Asbestos Removal Contractors with a Class A or B license for the removal of 10m 2 or more of non-friable ACM and any associated asbestos containing dust or debris (ACD) associated with the removal Contractors who can show evidence of industry trainingassociated with the identification, safe handling of, and suitable control measures for asbestos and ACM for the removal of less than 10m 2 of non-friable ACM associated with works projects Authorised PWCNT Staff who have agreed to and have been provided training as approved by NT Worksafe for the incidental removal of a minor contamination of non-friable asbestos containing debris. George Brown Darwin Botanic Gardens Asbestos Management Plan Page of 37

10 The annual allocation of Contractor funding to remove ACM throughout PWCNT workplaces will be determined by PWCNT s Chief Executive Officer, taking into consideration the factors above, and the works arranged through the Technical Services Division. Asbestos registers will be updated by the Asbestos Management Coordinator when ACM is removed from the site ON-SITE MANAGEMENT OF ACM ACM IN BUILDINGS, STRUCTURES OR EQUIPMENT Where removal is not practical in the short-term and there is a high risk of asbestos fibres becoming airborne, the ACM will be enclosed or sealed, as recommended by a competent person. An enclosure is the creation of a structure or barrier built around the asbestos so that it is completely covered. Enclosures create a separate physical barrier that prevents access to the asbestos and therefore minimises the potential for exposure to airborne fibres. Enclosures are only used on non-friable asbestos where removal is not reasonably practical and where the asbestos is at risk of damage from work activities. Sealing is the process of covering the surface of the material with a protective coatingover the asbestos to prevent exposure to airborne asbestos fibres. Sealing is an interim control while more effective control such as removing or enclosing can be implemented. A mixture of water and PVA glue is an effective temporary sealant for damaged nonfriable asbestos, applied with a spray bottle using a low pressure misting spray. The use of enclosures or sealing is not necessary where non-friable bonded ACM is in a good condition and not at risk of damage from work activities or the environment. The monitoring of in-situ ACM is important to ensure ACMs are not damaged or deteriorated over time. Inspections of in-situ ACM will be conducted annually by the Technical Services Division and at least every five years by a licensed asbestos assessor. The asbestos register will be updated by the Asbestos Management Coordinator when ACM is enclosed or sealed and with the completion of annual inspections. (i) NON-FRIABLE ASBESTOS DEBRIS AND SUB-SURFACE GROUND CONTAMINATION All visible non-friable ACM surface debris identified on park grounds will be programmed for removal as soon as reasonably practicable. Until such time as the asbestos debris is removed: the area containing the debris will be signposted; and, access limited to pedestrian traffic and light vehicles (where necessary for operational purposes); and, maintenanceworks conducted in the areas is to be carried out following a safe work procedure recommended by a competent person. Where ACM surface debris has been identified on the ground and where recommended by a competent person,soil samples in the immediate area to a depth of 100mm will be analysed to determine likely contamination of sub-surface ground material. Where the results of soil samples indicate that sub-surface ground contamination is unlikely and the visible ACM surface debris is removed, the area will be cleared for normal use. Until such time as an entire site has been remediated, there is a potential for ACM debris to be transported to cleared areas. To minimise the risk of disturbing this material, cleared areas are to be inspected for surface debris by staff after weather events prior to carrying out maintenance in these areas. Where the results of the soil samples indicate that sub-surface ground contamination is likely,remediation measures as recommended under the National Environment Protection Measure (NEPM) guidelines will be implemented. The NEPM s principles for remediation and management of contaminated sitesinclude: on-site treatment of the soil, so that the contaminant is either destroyed or the associated hazard is reduced to an acceptable level off-site treatment of excavated soil, so that the contaminant is either destroyed or the associated hazard is reduced to an acceptable level, after which it is returned to the site. removal of contaminated soil to an approved site or facility, followed by (where necessary) replacement with clean fill isolation of the contamination on-site a less sensitive land use to minimise the need for remedial works leaving contaminated material in-situ providing there is no immediate danger to the environment or community and the site has appropriate management controls in place. A combination of the principles above will be applied at PWCNT Workplaces. To minimise the risks associated with removal and treatment and the resources required to relocate and permanently manage the material off-site, preference is given to on-site management where possible. On-site management principles that will be applied to sub-surface contaminated sites include: stabilisation of drainage channels to prevent erosion adaptive management of contaminated sites to reduce maintenance requirements George Brown Darwin Botanic Gardens Asbestos Management Plan Page of 37

11 application of top soil, fill or other material to a depth suitable for intended use, including: Regular maintenance work and heavy pedestrian traffic Vehicle and machinery access roads Minimal maintenance work and occasional pedestrian traffic Areas that will require sub-surface excavation to maintain services 100mm top soil or fill. Material stabilised with grass, ground covers, rock mulch or similar. 200mm road base fill or 100mm fill with bitumen capping Surface mulching and erosion control Filled to at least the depth of required excavation Where practical, permeable geotextile material is to be used between contaminated infill material and a laid surface. Where contaminated soil must be removed from the ground to carry out works or for the purpose of remediation it will be treated as asbestos waste and removed from site or contained on site where approved by the Environmental Protection Authority (EPA). The planning of works for the remediation of contaminated sites will be managed by the Director of the workplace in consultation with the Regional Technical Services Unit and Asbestos Management Coordinator. Funding bids for remediation works will be submitted through the Repairs and Maintenance Program STANDARD OPERATING PROCEDURES AND SAFE WORK PRACTICES The following standard operating procedures (SOPs) and safe work practices apply at PWCNT workplaces. (i) ASBESTOS RELATED WORK PERMITS Work involvingasbestos (other than licensed asbestos removal work) where there is a potential risk ofexposure toairborne asbestos fibres is deemed asbestos related work. Such work must only be carried out by licensed asbestos contractors or in accordance with asbestos related safe work procedures developed by a competent person and approved for use by the Asbestos Management Coordinator. Asbestos related work includes: sampling maintaining or working on non-friable ACM removal or disposal of less than 10m 2 of ACM or a minor contamination of ACD Authorisation to conduct asbestos related work at PWCNT workplaces will be provided: for Contractors by the Asbestos Management Coordinator; or for PWCNT staff by the Chief Executive Officer Only staff and contractors trained in the identification, safe handling, and suitable control measures for ACM will be authorised to carry out asbestos related work. Staff responsible for arranging worksthrough Contractors or other Government Agencies that is likely to disturb asbestos must obtain an Asbestos Related Work Permit (Appendix A) from the Asbestos Management Coordinator prior to the commencement of the work. Records of asbestos related work permits will be maintained by the Asbestos Management Coordinator, and the asbestos register updated when asbestos related work is carried out. (ii) CONTROLLED USE OF TOOLS AND EQUIPMENT In line with Work Health and Safety regulations the following are not permitted to be used on ACM: high-pressure water spray for any purpose other than fire fighting or fire protection compressed air In addition, the use of power tools, brooms and any other equipment on ACM that may release airborne asbestos fibres in the workplace are not permitted unless controlled in a way that is designed to capture or suppress airborne asbestos safely. The use of equipment on ACM is asbestos related work. (iii) EXCAVATING SOIL ON CONTAMINATED SITES Where surface ACM debris contamination has been identified there is a possibility that some material is contained below the surface. Where a competent person has identified that sub surface ACM contamination is likely: all excavated material must be treated as asbestos waste and removed by a licensed asbestos removalist; or a safe work method as recommended by a competent person is to be used and is asbestos related work. George Brown Darwin Botanic Gardens Asbestos Management Plan Page of 37

12 Where soil sampling or site investigation by a competent person indicates that sub-surface ACM contamination is unlikely, soil may be excavated following a written safe work procedure approved for use by the Asbestos Management Coordinator. EXCAVATION MAP To assist in the identification of areas where excavation can safely be carried out at the George Brown Darwin Botanic Gardens, a map is maintained by the Curator and will be made available to staff and contractors indicating the following areas: excavation with no asbestos related restrictions (applicable to areas where no asbestos surface or subsurface debris has been identified) excavation allowed following an approved safe work procedure (applicable to areas where surface debris has been identified and removed and sub-surface debris is unlikely) excavation as asbestos related work only (applicable to areas where sub-surface debris is likely) The map will be regularly updated with any change in status and is located at the Selonika Street Workshop and Orientation Centre. (iv) MOWING AND SLASHINGON CONTAMINATED SITES Mowing and slashing where surface ACM debris has been identified in the asbestos register and not previously removed through an emu-bob will be carried out as asbestos related work and all material including cuttings treated as asbestos waste. An asbestos related work permit is required to carry out mowing and slashing on sites if undertaken prior to the removal of ACM surface debris. Where ACM surface debris has been removed,the asbestos related risk to health from mowing and slashing is negligible and is not considered asbestos related work where: the surface ACM debris identified in the register has been removed and the site cleared of visible debris by a competent person; and a visual inspection by the operator confirms no observable ACM presentora visual inspection by the operator confirms only a minor contamination of ACM debris which is either removed prior to mowing or slashing or isolated and excluded from work area; and the risk of disturbing any sub-surface contamination is negligible; and appropriate PPCE is used. The risk of disturbing sub-surface contamination can be reduced by: sampling to confirm soil unlikely to contain sub-surface contamination; or only mowing or slashing level surfaces with well-maintained grass cover; or covering contaminated soil surface with 100mm clean fill barrier; or using cutting equipment that produces negligible dust and can be maintained at least 100mm above contaminated soil surfaces. Mowing or slashing in areas where surface contamination has been identified may be carried out under these conditions by staff and contractors following a safe work procedure approved for use by the Asbestos Management Coordinator. MOWING MAP To assist in the identification of areas where mowing and slashing can safely be carried out at the George Brown Darwin Botanic Gardens, a map is maintained by the Curator and will be made available to staff and contractors indicating areas: mowing/slashing with no asbestos related restrictions (applicable to areas where no asbestos surface or subsurface debris has been identified or after an area has been remediated through the complete removal, clearance provided for top 100mm soil surface, or capping of the area) mowing/slashing allowed following an approved safe work procedure (applicable to areas where any identified surface ACM debris has been removed by emu-bob and a clearance certificate has been recorded in the asbestos control log) mowing or slashing as asbestos related work only (applicable to areas where surface debris has been identified and not removed by emu-bob). The map will be regularly updated with any change in status and is located Selonika Street Workshop and Orientation Centre. (v) USING AND MAINTAINING ASBESTOS REGISTERS. To ensure the asbestos register is used and maintained in compliance with legislation the SOP Using and Maintaining Asbestos Registers (Appendix B) has been developed. The procedure details: the location of the register George Brown Darwin Botanic Gardens Asbestos Management Plan Page of 37

13 requirements for reviewing the register the role of the Asbestos Management Coordinator how the register is updated communicating changes to the register roles and responsibilities (vi) LICENSED ASBESTOS REMOVAL. To minimise risk of exposure to airborne asbestos fibres, the process of removing asbestos from the workplace is strictly regulated under the Northern Territory s Work Health and Safety (National Uniform Legislation) Act. The SOP Licensed Asbestos Removal (Appendix C) has been developed to ensure PWCNT complies with its obligations under the Act. The procedure covers the removal of any quantity of friable or non-friable ACM and details: when a licensed asbestos removalist must be used who can commission licensed asbestos removal work responsibilities of licensed asbestos removalists commissioned by PWCNT limiting access to asbestos removal work areas clearance inspections requirements for air monitoring communicating when asbestos removal work is to be carried out roles and responsibilities (vii) REPAIRS, MAINTENANCE AND NEW WORKS Carrying out work on ACM that has a potential to result in exposure to airborne asbestos fibres will be eliminated as far as reasonably practical. Where it is identified that minor works projects or maintenance may disturb identified ACM, the feasibility of alternative work methods or the removal of the ACM will be considered first. All works projects involving refurbishment or demolition of buildings or equipment will not be undertaken until identified ACM is removed appropriately. Where asbestos related work must be undertaken and this work will not be carried out by a licensed asbestos contractor, a safe work procedurewill be developed in consultation with a competent person and approved for use by the Asbestos Management Coordinator, prior to the work being undertaken. Approved safe work procedures for the following asbestos related works are detailed in the NT Worksafe Code of Practice for How to Manage and Control Asbestos in the Workplace: Drilling of asbestos containing material Sealing, painting, coating and cleaning of asbestos cement products Working on electrical mounting boards containing asbestos Cleaning leaf litter from gutters of asbestos cement roofs Replace cabling in asbestos cement conduits or boxes George Brown Darwin Botanic Gardens Asbestos Management Plan Page of 37

14 MINOR REPAIRS AND MAINTENANCE WORKS PROCESS Repair or maintenance works identified. Type and location of work assessed against the asbestos register for the site. Confirmed no ACM in the location of the works. Works request submitted, works carried out as normal. ACM has been identified or assumed at the location of the works. (Assumed ACM may be sampled to confirm presence.) Confirmed no asbestos related work included in scope of works. Scope of works assessed for inclusion of asbestos related work. Works request submitted advising that: ACM has been identified at the location of the works any changes to the scope of works are not permitted until the asbestos register is reviewed by the contractor where the revised scope of works will result in the disturbance of ACM PWCNT is to be notified before carrying out works. Scope of works includes asbestos related work. ACM can be removed before works carried out or alternative work method can be used to prevent disturbing ACM Arrangements made for removal of ACM through DOI or alternative work method approved and revised works completed. ACM cannot be removed before works carried out or no alternative work method suitable Work request to include requirement for a safe work procedure to be developed by a competent person and approved for use by the Asbestos Management Coordinator. Safe work procedure for asbestos related works, and requirement for contractor to collect a copy of asbestos register prior to carrying out works, included in scope of works. Works completed.

15 REFURBISHMENT AND DEMOLITION WORKS PROCESS Works involving refurbishment or demolition identified. Asbestos register for site reviewed No asbestos register for site as building or equipment installed post 31 December 2003 Works request submitted to DOI, works carried out as normal. ACM has been identified or assumed at the site or building and/or equipment installed prior to December Assessor confirms no asbestos present. Pre-refurbishment/demolition asbestos survey carried out by asbestos assessor Works request submitted, works carried out as normal. Details of identified asbestos updated in register. Arrangements made for removal of ACM through DOI. Scope of works for removal of asbestos developed by competent person. Refurbishment or demolition works undertaken after ACM removed and clearance inspection received from authorised asbestos assessor AIR MONITORING Air monitoring to detect if the airborne concentration exposure standard of 0.01fibres/ml is exceeded will be conducted: for all Class A licensed asbestos removal for the removal of friable ACM following in-situ ACM condition assessments where a competent person recommends air monitoring to determine present risk to health as recommended by a competent person when there is uncertainty as to whether the exposure standard is likely to be exceeded during other asbestos related work as required to address public concern during other asbestos related works The results of air monitoring will be maintained in Trim for 30 years and are readily accessible to persons who may be exposed.

16 10. IDENTIFICATION OF SUSPECTED ACM DEBRIS Whilst an inspection has been undertaken to identify (as far as reasonably practicable) asbestos containing materials, due to unknown building practices and the potential for external factors such as weathering uncovering previously unidentified ACM debris, asbestos containing material could be unexpectedly encountered in asset grounds. The following procedure is to be followed where suspected ACM debris is encountered. PROCEDURE FOR THE DISCOVERY OF SUSPECTED ACM DEBRIS Step Who Action 1.Stop work 2. Restrict Disturbance of Material PWCNT Staff or contractors in affected area PWCNT Staff or Contractor - Cease work activities which may disturb material - vacate immediate area if suspect material likely to be friable and there is a risk of air-borne fibres being released Where suspect material is likely to be friable: - erect warning tape around area a distance no less than 10 mtrs from the suspect material and install danger signage restricting access to authorised personnell only visible from all entrance points to area Where suspect material is likely to be non-friable: - erect warning tape directly around the area containing the suspect material: or, - insert marker peg (fence dropper or similar) wrapped with warning tape in ground adjacent to single pieces of material but NOT contacting material AND - install temporary signage identifying asbestos present in area. 3. Report Find Contractor - Report find to PWCNT Staff on site 4. Sample Material and Assess Risk 5. Implement Control Measures 6. Update Asbestos Register and communicate changes PWCNT Staff at workplace Workplace Supervisor Regional Technical Services Unit Officer Regional Technical Services Officer Asbestos Management Coordinator Regional Technical Services Officer Manager of Workplace - Report find to immediate workplace Supervisor - Report find to workplace Manager and regional Technical Support Services Unit. - The details to be reported must include: o exact location of find (including GPS coordinates and/or map) o when and how the material was discovered o the type of material (product) and likely condition (friable/bonded) including photos if possible o what immediate control measures have been implemented - The Technical Services Unit will arrange sampling and risk assessment and provide the results to the workplace Manager and Asbestos Management Coordinator. (note sampling is not required if material is assumed to be ACM) - Where ACM is confirmed through sampling or assumed the Technical Services Unit will arrange for the removal of the asbestos under the Repairs and Maintenance Program. - Follow procedures identified in the Using and Maintaining Asbestos Registers standard operating procedure. George Brown Darwin Botanic Gardens Asbestos Management Plan Page of 37

17 11. EMERGENCY RESPONSE PROCEDURES To prevent disturbance and spread of asbestos fibres from accidental, structural, fire or storm damage, or when previously unidentified ACM is discovered within a building or equipment during works projects, the following procedure is to be followed. EMERGENCY PROCEDURE FOR ACCIDENTAL, STRUCTURAL, FIRE OR STORM DAMAGE TO ACM OR DISCOVERY OF PREVIOUSLY UNIDENTIFIED ACM IN BUILDINGS OR EQUIPMENT. Step Who Action 1.Stop work 2. Restrict access to affected area & shut-off air handling system (if relevant) PWCNT Staff or contractors in affected area PWCNT Staff or Contractor - Cease all work activities and vacate affected area - Restrict access to the area - Put up temporary signage to prevent site or building occupants or members of the public from entering the immediate area, and to prevent any further disturbance of asbestos materials in the area. - Air handling systems should be shut-off (where relevant). 3.Report Incident Contractor - Report incident to PWCNT Staff on site PWCNT Staff at workplace - Report incident to immediate Supervisor Supervisor - Complete a PWCNT WHS incident report form - Report incident to Workplace Manager and Regional Technical Services Unit Workplace Manager - If the damage resulted in a serious risk to health from significant exposure to airborne asbestos fibres, report the confirmed exposure immediately to NT Worksafe. - Where a reportable incident has occurred the site of the incident must be left undisturbed until inspected by NT Worksafe Director of Technical Services - If the structure is unsound or likely to collapse, immediately Notify NT Worksafe in writing. 4.Risk Assess Damage Regional Technical Services Officer - Arrange asbestos assessor to: attend site and undertake risk assessment of damage; take sample of assumed ACM if necessary; and, provide recommendations for management. (Sampling should be considered necessary when required to confirm exposure or where the cost of control would be a significant factor). Where assumed asbestos is sampled and tests negative for asbestos Go to Step 7. Where assumed asbestos is sampled and tests positive for asbestos, or where assumed asbestos is not sampled but is to be treated as asbestos containing material Go to Step 5. George Brown Darwin Botanic Gardens Asbestos Management Plan Page of 37

18 EMERGENCY PROCEDURE FOR ACCIDENTAL, STRUCTURAL, FIRE OR STORM DAMAGE TO ACM OR DISCOVERY OF PREVIOUSLY UNIDENTIFIED ACM IN BUILDINGS OR EQUIPMENT. Step Who Action 5. Remove, enclose, or seal damaged ACM and clean up Regional Technical Services Officer - Arrange works to be undertaken and liaise with Manager of workplace to ensure relevant persons are made aware of proposed works Manager of Workplace - Ensure all relevant persons are made aware of proposed works 6. Clearance inspection Regional Technical Services Officer - Arrange clearance inspection as required under legislation - copy of clearance inspection report to Asbestos Management Coordinator for Workplace. 7. Notify staff Manager of Workplace - Communicate completion of works to all relevant persons 8. Update Asbestos Register and communicate changes Asbestos Management Coordinator Regional Technical Services Officer Manager of Workplace - Follow procedures identified in the Using and Maintaining Asbestos Registers standard operating procedure EVACUATION In the event of an emergency it may be necessary to evacuate a building or the site. Where the emergency event results in damage to a building with asbestos containing materials and the building has become structurally unsound requiring demolition or where collapse of the building is likely to occur then: a procedure will be developed as recommended by a competent person to reduce the risk of exposure to air borne asbestos in the vicinity of the site; and the regulator will be notified. Where asbestos removal work is being undertaken at the time of the emergency and asbestos removalists are required to evacuate, decontamination procedures may be temporarily waived. The decision will be based on an informal risk assessment conducted at the time by the person supervising the removal work. Persons involved in asbestos removal must evacuate to the evacuation assembly point but remain downwind to ensure any fibres remaining on clothes, as a result of not decontaminating completely, do not enter the breathing space of others. Upon arrival at the evacuation point, emergency wardens and health and safety personnel are to be notified of the risk associated with the status of the asbestos removal work, as well as the assessed level of risk associated with asbestos removalists not undergoing the complete decontamination process. 12. INCIDENT REPORTING All incidents involving the potential uncontrolled release of airborne asbestos fibres must be recorded on a PWCNT OH&S incident report. The Work Health and Safety (National Uniform Legislation) Act requires prescribed notifiable incidents to be reported to the Regulator. Notifying the Regulator of fatalities, serious injuries or dangerous incidents that expose persons to serious risks to their health or safety allows causes of incidents to be identified. The information can be used to help prevent similar incidents at that workplace as well as other workplaces. Where the immediate or imminent exposure to airborne asbestos fibres is likely to create a serious risk to a person s health or safety in the future, the Regulator must be notified that a Dangerous Incident has occurred. Only the most serious safety incidents are intended to be notifiable, and they trigger requirements to preserve the incident site pending further direction from the Regulator. George Brown Darwin Botanic Gardens Asbestos Management Plan Page of 37

19 Risk to health from an incident involving asbestos is subject to the following factors: whether the asbestos material involved was friable or non-friable (potential for fibres to be released) the type of material (the amount of asbestos contained in the material) the likelihood that the material was damaged in a way that could release fibres into the air (drilling, high pressure water, compressed air, etc) exposure (how long the person was likely to be exposed to the airborne fibres) As a guideline to assessing if an incident is reportable, during licensed asbestos removal requiring air monitoring, asbestos removalists are required to stop work and notify the regulator where respirable asbestos fibre levels exceed 0.02fibres/ml (equivalent to 20,000 fibres per cubic metre). 13.INFORMATION AND TRAINING Asbestos awareness training will be provided to all staff. This training may be provided in-house by Management or by an external competent person. The training provided will include information on: the health risks associated with asbestos the types, uses and presence of asbestos in the workplace including identification through labelling and signs what the asbestos register is and where it is located individual responsibilities in relation to asbestos management safe work practices All Contractors will be provided a copy of PWCNT s Asbestos Management Handbook for Contractors on induction to site. As required by the Act, staff or contractors required to carry out asbestos related work are to undertake additional asbestos awareness training. This training will include information on the identification, safe handling and suitable control measures for managing asbestos. Workplace managers will arrange this additional training for staff as required. Contractors (other than licensed asbestos removalists) commissioned to carry out asbestos related workfor PWCNT, are required to provide written evidence of asbestos awareness training for their workers, prior to carrying out the works. Evidence of asbestos awareness training for contractors will be collected and recorded by the Asbestos Management Coordinator prior to the approval of Asbestos Related Work Permits. Information sheets on the Health Risks and Asbestos Types, Use and Presence in the Workplace are provided at appendix D and E to this Management Plan. Asbestos related information is also readily available online to staff, contractors and visitors of PWCNT workplaces, including: NT Worksafehttp:// NTG Department of Health Australian Government Department of Health and Aging REVIEW As required by the regulations, this Asbestos Management Plan will be reviewed and revised as necessary when: there is a review of an asbestos register or a control measure asbestos is removed from, or disturbed, sealed or enclosed at a workplace the plan is no longer adequate for managing asbestos or asbestos containing material This Asbestos Management Plan will be reviewed at least once every five years.

23 PARKS AND WILDLIFE COMMISSION OF THE NORTHERN TERRITORY 17.APPENDIX C LICENSED ASBESTOS REMOVAL PWCNT - LICENSED ASBESTOS REMOVAL PURPOSE STANDARD OPERATING PROCEDURE This procedure has been developed to ensure the legislated requirements that must be taken by PWCNT, under the Northern Territory s Work Health and Safety (National Uniform Legislation) Regulations are complied with in relation to asbestos removal from PWCNT workplaces. SCOPE This procedure is applicable to all employees of the Parks and Wildlife Commission: Alice Springs Desert Park, George Brown Darwin Botanical Gardens, Parks and Wildlife, Territory Wildlife Park, Window on the Wetlands. This procedure covers the removal of any quantity of friable and non-friable (bonded) asbestos containing material (ACM). STANDARD OPERATING PROCEDURE DETAIL 1. Using Licensed Asbestos Removalists All friable ACM is only to be removed from a PWCNT workplace by asbestos removalists with a current Class A asbestos removal license. Friable ACM is material that contains asbestos and is in a powder form or can be crumbled, pulverised or reduced to a powder by hand pressure when dry. All non-friable ACM in quantities of greater than 10m 2 is only to be removed from a PWCNT workplace by asbestos removalists with a current Class A or Class B asbestos removal license. The removal of less than 10m 2 of non-friable ACM or a minor contamination of ACM dust or debris does not require a license but is classed as asbestos related work. Contractors who can show evidence of industry training associated with the identification, safe handling of, and suitable control measures for asbestos and ACM may be authorised to remove less than 10m 2 of non-friable ACM associated with works projects. PWCNT Staff who have agreed to and have been provided training as recommended by NT Worksafe may be authorised by the Chief Executive Officer to undertake the incidental removal of a minor contamination of non-friable asbestos containing debris following an approved safe work procedure. Identified ACM in the workplace is noted as friable or non-friable (non-friable may be noted by some asbestos assessors as stable or bonded) in the asbestos register for a workplace as determined by a competent person. 2. Asbestos Related Work Permit Asbestos removal work (excluding incidental removal of a minor contamination of non-friable ACM debris) must only be carried out by licensed asbestos contractors or in accordance with asbestos related safe work procedures developed by a competent person and approved for use by PWCNT s Asbestos Management Coordinator. Staff responsible for arranging works must obtain an Asbestos Related Work Permit from the Asbestos Management Coordinator prior to the commencement of any asbestos removal. 3. Asbestos Removal Work All licensed asbestos removal will be conducted by external contractors commissioned by the Department of Infrastructure. All asbestos removal work is to comply with the requirements under the Act. The following must be carried out by contractors commissioned to remove asbestos at PWCNT workplaces: ensure each worker carrying out the asbestos removal work is trained according to the regulations inform each asbestos removal worker about the health risks provide health monitoring of asbestos removal workers where required under the regulations complete an asbestos removal control plan and provide this to PWCNT Technical Services Division prior to commencing work (a control plan is not required for unlicensed asbestos removal work however PWCNT Technical Services Division must be notified by details on how the asbestos removal will be carried out) notify the regulator at least 5 days before licensed removal work is to commence (where removal must be carried out immediately to prevent exposure the regulator is to be notified immediately by phone and also within 24 hours in writing) ensure that signs are displayed to alert to the presence of asbestos removal work and barricades are erected to delineate the asbestos removal area provide and use appropriate decontamination facilities

24 be responsible for disposing of asbestos waste from the asbestos removal work area Only PWCNT Technical Services Division Officers can arrange through the Department of Infrastructure the commissioning of asbestos removal work at PWCNT workplaces managed and controlled by PWCNT. 4. Limiting Access to Asbestos Removal Work Areas Managers in charge of a workplace must ensure, as far as reasonably practical, access to a work area where asbestos removal is being undertaken is limited to: workers engaged in the asbestos removal work; authorised inspectors; independent Air Monitoring Consultants; NTG Project Officers directly involved with the delivery of the works Access to an asbestos removal area by these authorised persons is to be at the direction of the asbestos removalist Supervisor. 5. Clearance Inspections Unless otherwise approved by NT Worksafe, for Class A licensed asbestos removal work, a licensed asbestos assessor, not commissioned or employed by the removalist must undertake a clearance inspection and provide a written clearance inspection certificate to PWCNT. Unless otherwise approved by NT Worksafe, for Class B licensed asbestos removal work, a licensed asbestos assessor or competent person who is not commissioned or employed by the removalist must undertake a clearance inspection and provide a clearance inspection certificate to PWCNT. For all other asbestos removal work notification that the area has been visually inspected and the area is safe for reoccupation for normal use is required for clearance. Clearance Inspection reports are to be requested by the Technical Services Division when arranging works through the Department of Infrastructure. Clearance reports are to be ed to the Asbestos Management Coordinator for recording in TRIM. 6. Air Monitoring Air monitoring is to be arranged for: Class A (friable) asbestos removal work prior to removal and whilst asbestos is being removed. for other asbestos removal as recommended by a competent person when there is uncertainty as to whether the exposure standard is likely to be exceeded as required to address public concern Managers of a workplace are to ensure the results of air monitoring are available to: workers at the workplace Health and Safety Representatives at the workplace anyone else at the workplace Air monitoring is to be requested by the Technical Services Division when arranging works through the Department of Infrastructure. The results of air monitoring are to be ed to the Asbestos Management Coordinator for recording in TRIM. 7. Communication Before any licensed asbestos removal work commences the Manager of the workplace must ensure as far as reasonably practical that all relevant stakeholders, including staff, contractors, visitors, and persons and businesses in close proximity to the work are advised that the asbestos removal work is to be undertaken. ROLES AND RESPONSIBILITIES Person/Parties Technical Services Division Roles and Responsibilities Reviewing the asbestos register prior to submitting works requests to the DOI Obtaining an asbestos related work permit from the Asbestos Management Coordinator Providing a copy of the asbestos register and management plan to Contractors carrying out asbestos removal work Providing electronic copies of all asbestos related work documents associated with asbestos removal to the Asbestos Management Coordinator Managers of a workplace where asbestos has been identified Informing all relevant stakeholders about the asbestos removal works Restricting access to asbestos removal areas Communicating results of air monitoring

26 18. APPENDIX D ASBESTOS HEALTH RISK INFORMATION SHEET ASBESTOS HEALTH RISK INFORMATION SHEET The Australian Government Department of Health and Aging has the following advice in relation to the health impacts and risk associated with asbestos. Asbestos only poses a risk to health when asbestos fibres are breathed in. Undisturbed asbestos cement materials in good condition do not pose a health risk because the asbestos fibres are bound together in solid cement. However, if the material is damaged or crumbling (that is, has become friable), or is disturbed by breaking, cutting, drilling or sanding, fibres are released into the air. Friable asbestos products (such as spray-on insulation or asbestos-rope gaskets in wood stoves and heaters) also produce airborne fibres during normal use or ageing. Crumbling bonded materials, and all friable products, must be carefully managed to prevent the release of fibres into the air. ASBESTOS-RELATED DISEASES When asbestos fibres are breathed in, they may remain deep within the lungs. They can lodge in lung tissue and cause inflammation, scarring and some more serious asbestos-related diseases, which usually take many years, if not decades, to develop. The four major asbestos-related diseases are shown below in increasing order of severity. A person may show signs of more than one of these diseases. PLEURAL PLAQUES ASBESTOSIS LUNG CANCER MESOTHELIOMA areas of white, smooth, raised scar tissue on the outer lining of the lung, internal chest wall and diaphragm often the earliest sign of exposure to asbestos not everyone who has been exposed to asbestos develops plaques, possibly because of differences in their immune response to asbestos fibres people with pleural plaques as their only asbestos related symptom usually have very little impairment of lung function a chronic condition caused by inflammation or scarring in the lungs causes shortness of breath, coughing and permanent lung damage caused by heavy, prolonged exposure to asbestos cancerous tumours that mainly occur in the lining of the tubes leading into the lungs, the smaller airways or the middle of the lungs risk of developing lung cancer is increased in people who also smoke or have a pre-existing lung disease cancer of the tissue that lines the body cavities, particularly the chest and abdominal cavities almost always caused by exposure to asbestos; about 90% of all mesothelioma patients have a confirmed history of asbestos exposure, usually because they have worked in an asbestos-related industry. Risk factors for developing asbestos-related diseases The risk of developing an asbestos-related disease increases in proportion to the number of asbestos fibres a person breathes in during their life. This, in turn, depends on how many fibres are breathed in and how often. NUMBER OF FIBRES BREATHED IN DURING EACH EXPOSURE (THE DOSE) The risk of developing an asbestos-related disease increases when a larger number of fibres is breathed in. THE NUMBER OF TIMES A PERSON IS EXPOSED OVER TIME ( CUMULATIVE DOSE OR LIFETIME EXPOSURE )

27 However, very occasional exposure to a larger number of asbestos fibres (e.g. unsafe home renovation or demolition next door) is unlikely to be harmful. But frequent exposure to a larger number of asbestos fibres (e.g. builder or tradesperson using unsafe techniques) is much more likely to be harmful. For practical purposes all types of asbestos (white, brown and blue) should be treated as equally hazardous WHO IS AT RISK OF DEVELOPING ASBESTOS-RELATED DISEASES? We are all exposed to low levels of asbestos in the air we breathe every day. Ambient or background air usually contains between 10 and 200 asbestos fibres in every 1000 litres (or cubic metre) of air (equivalent to 0.01 to 0.20 fibres per litre of air). However, most people do not become ill from this exposure, because the levels of asbestos present in the environment are very low. Most people are also exposed to higher levels of asbestos at some time in their lives; for example, in their workplace, community or home. However, for most people, this kind of infrequent exposure is also unlikely to result in any ill effects. Most people who develop asbestos-related diseases have worked on jobs where they frequently breathed in large amounts of asbestos fibres. For example, in the past, construction workers using unsafe practices may have frequently encountered asbestos fibre levels well above background levels. The current regulated workplace limit (over an eight-hour period) is 100 fibres per litre of air (which is between 500 and times background levels). In the past, workers in asbestos milling or mining often encountered fibre concentrations a million times higher than background levels. Family members of exposed workers or those who lived close to active asbestos mines (Australia now has none) are also at risk. An exposed worker can carry asbestos fibres on their clothing, skin and hair when they return home. Other workers may have used waste products from asbestos mines or manufacturing plants to surface driveways or paths at home. Although there is no absolutely safe level of exposure to asbestos fibres, occasional exposure to low levels of fibres poses only a low risk to your health. A very small number of asbestos-related disease cases occur each year in people who have not worked with asbestos products. The low number of cases makes it difficult to determine the exact cause of the disease or the likely exposure event, but unsafe handling of asbestos materials in the home may have contributed to some of these cases. Asbestos-related risk Risk Dose Exposure Who Description Very low Background All the time General public All air has a low level of asbestos fibres Low 10s 100s x Background Occasional Householder Incident such as unsafe renovation or demolition next door Medium 100s 1000s x Background Occasional Home renovator Unsafe removal of asbestos in home renovation High 100s 1000s x Background Regular Builder/tradesperson Frequent exposure to high levels of asbestos by builders, etc if using unsafe practices Extreme Millions x Background Daily Asbestos mine worker (Note: All asbestos mining in Australia stopped by 1983)

29 19. APPENDIX E ASBESTOS TYPES, USE AND PRESENCE IN THE WORKPLACE INFORMATION SHEET ASBESTOS TYPES, USE, AND PRESENCE IN THE WORKPLACE - INFORMATION SHEET The following information has been reproduced from A handbook for workplaces Asbestos, Ed. 1, September 2008 and adapted for relevance to the Northern Territory with the permission of Worksafe Victoria. What is asbestos? Asbestos is the name given to a group of fibrous silicate minerals that occur naturally in the environment. Asbestos was commonly used in a wide variety of industrial, manufacturing, building and construction applications in Australia between the 1940s and late 1980s. It has been used in the manufacture of more than 3000 products because of its durability, fire resistance and excellent insulating properties. The three main types of asbestos are: chrysotile (often called white asbestos) crocidolite (often called blue asbestos) amosite (often called brown asbestos). Other less common forms of asbestos include actinolite, anthophyllite and tremolite. Under the Northern Territory of Australia Work Health and Safety (National Uniform Legislation) Regulations asbestos is defined as: the asbestiform varieties of mineral silicates belonging to the serpentine or amphibole groups of rock forming minerals including the following: a) actinolite asbestos; b) grunerite (or amosite) asbestos (brown); c) anthophyllite asbestos; d) chrysotile asbestos (white); e) crocidolite asbestos (blue); f) tremolite asbestos; g) a mixture that contains 1 or more of the minerals referred to in paragraphs (a) to (f). There is no simple test to identify asbestos an approved laboratory analysis is the only certain method. What is asbestos-containing material? Asbestos-containing material (ACM) is any material or object that, as part of its design, contains one or more of the mineral silicates referred to above (other than plant in which asbestos is fixed or installed). ACM can be friable or non-friable. Friable ACM when dry: a) may be crumbled, pulverised or reduced to powder by hand pressure, or b) as a result of a work process, becomes such that it may be crumbled, pulverised or reduced to powder by hand pressure. Examples of friable ACM include: pipe lagging boiler insulation fire retardant material on steel work sprayed insulation. Non-friable ACM is usually bonded or mixed with cement or similar material and cannot be crumbled, pulverised or reduced to powder by hand pressure. Examples of non-friable ACM include: asbestos cement sheet asbestos cement moulded products bitumen-based water proofing vinyl floor tiles in good condition. Some examples of non-friable ACM that can become friable as a result of work process include the handling of millboard in poor condition, asbestos cement sheeting that has been crushed and asbestos cement sheeting that has deteriorated from long-term exposure to a chemical mist. Where can you find asbestos? A large amount of ACM is still present in the community in both workplaces and on-workplaces, including domestic premises. In the past, the asbestos cement manufacturing industry was the main consumer of asbestos fibres to produce products such as:

30 Other common ACMs include: asbestos cement roofing external asbestos cement sheet walls, including brick cladding internal asbestos cement sheet walls and ceilings moulded products such as flues, downpipes, guttering, water and sewerage pipes. textiles asbestos felts, ropes, fire blankets and woven asbestos cable sheathing flooring vinyl floor tiles and sheets sprayed insulation materials used for fire-proofing, thermal protection, insulation and soundproofing lagging and other loosely bound insulation materials used in a wide range of electrical, thermal and acoustic applications rubber, plastic and paint products (particularly industrial epoxy paints) sealants, gaskets, adhesives and filters brake pads and clutch mechanisms and other friction products. It is important for a person who manages or controls a workplace and employers or self-employed persons to be aware of the typical uses and applications of ACMs, particularly in any building constructed or renovated prior to the late 1980s. Typical locations for the most common asbestos materials Figure 1: Typical locations for the most common asbestos materials. Note: This diagram does not show all possible uses and locations of asbestos materials. A detailed survey will be required to identify all asbestos materials in a building.

31 Which occupations and trades are likely to come across asbestos? ACM was widely used in building and construction projects up to the late1980s. Many materials remain in place and, as a result, risk to workers is most likely to arise during asbestos removal or during renovation or maintenance work that disturbs asbestos. Occupations and trades that may come into contact with or work near asbestos include: Identifying asbestos demolition, roofing and construction contractors engineers (heating and ventilation or telecommunication) electricians painters and decorators joiners plumbers and gas fitters plasterers builders and building surveyors shop fitters fire and burglar alarm installers maintenance workers automotive repair workers. The following images demonstrate a range of ACMs that may be fixed or installed in workplaces: Figure 2: Saw-tooth design roof with corrugated asbestos cement roof sheets.

Figure 15: Detached asbestos rope seal and remnant debris on duct. Figure 16: Asbestos-containing zelemite electrical switchboard panel. Figure 17: Friable asbestos insulation in an electrical fuse housing.

34 Asbestos that is not fixed or installed Sometimes ACM is not fixed or installed to anything. However, it can still pose a health risk if an individual is exposed to airborne asbestos fibres from this material. Examples include: loose sheets of asbestos cement broken (non-attached) pieces of asbestos cement products surfaces contaminated with asbestos fibres/dust material containing asbestos debris products such as asbestos fire blankets, asbestos gaskets or asbestos brakes stored and awaiting use. Figure 18: Unfixed asbestos lagging from a pipe. Figure 19: These pieces of broken asbestos cement sheet are not fixed or installed.
