Page 4 of 16 BARRATT DEVELOPMENTS PLC SAFETY, HEALTH & ENVIRONMENTAL CODE FOR SUBCONTRACTORS SECTION 1 MANAGEMENT FOR SAFETY INTRODUCTION This Code had been prepared by Barratt Developments PLC (the Group) to assist in the achievement of safe working methods and practice on site. Whilst the Code is believed to be comprehensive, the Subcontractor should recognise that Safety, Health & Environmental regulations and publications are regularly updated and the Subcontractor is responsible for ensuring that they remain up to date with any changes that may occur and with best practice. Where the Group appoints a contractor to undertake the role of Principal Contractor under the Construction, Design and Management (CDM) Regulations this will be stated within the contractual arrangements and they must comply with the duties of a Principal Contractor as defined within these Regulations. ACKNOWLEDGEMENT OF SAFETY CODE The Subcontractor is required to sign and return the Acknowledgement in the front of this Code to the Divisional Office with which the contract was agreed. Subcontractors are required and will be deemed to have included copies of the Safety, Health & Environmental Code for Subcontractors in any subcontract let by them and shall make compliance with this Code a condition of any such subcontract. Any subcontracting of works must be notified in writing to the local Divisional Office for approval. (a) Safety Policy A written safety policy remains a statutory requirement under the Health and Safety at Work Act for any employer with five or more persons. Prior to commencement of work on site all Subcontractors will be required to provide a copy of their safety policy document. A copy of the Group Health and Safety Policy will be made available to the Subcontractor on request and it will also be available at each site. (b) Subcontractors Subcontractors must comply at all times with the requirements laid down in the Construction Phase Safety, Health and Environmental Plan. All Subcontractors will be expected to complete a questionnaire setting out details of their safety, health and environmental policy, training, health records, accident history, accident prevention, enforcement action and control measures. Subcontractor s personnel must be over 16 years of age (unless other restrictions apply), should be competent, fit and able for the work they are expected to undertake and have previously been given adequate information, instruction and training. Trained and experienced people shall supervise the work. Where the Division s apprentices are under the control of a Subcontractor they must be supervised by the Subcontractor s nominated foreman or manager to ensure their training requirements and general health and safety is in line with the Group s standards. Subcontractors shall not sublet work without written permission.
Page 5 of 16 (c) Supervision The Subcontractor shall ensure that sufficient supervision is available at all times when work is being undertaken on site. Supervisors shall be competent, experienced and trained as necessary. Certification will be required, minimum requirement will be the Construction Industry Training Board approved safety course. Subcontractors must submit the name of the individual responsible, on their behalf for health and safety on site, to the site management. This must also be stated in the Method Statement/Risk Assessment. (d) Pre-Start Meetings Subcontractors will be required to attend a pre-start meeting to discuss the necessary measures, which need to be implemented to reduce and control risks to workers and others. Regular meetings on site during the construction works will also be held to review the Subcontractors performance. Subcontractors may be required to hold their own meetings to discuss and review health and safety matters relevant to their operations. (e) Monitoring of Subcontractors The safety, health and environmental performance of Subcontractors will be monitored by various members of the Division s management team, and by their safety advisers. Subcontractors have a legal duty to ensure they have the services of a competent person to provide specialist health and safety assistance appropriate to their operations, this must be identified in their SMS. Subcontractors must be aware of the disciplinary arrangements, which apply in the event of a breach of Policy, Legislation or Site Rules, even if the breach does not result in an accident/injury. Such breaches may result in verbal and/or written warnings, work being stopped or Subcontractors being removed from site. On a regular basis the Division will complete an appraisal form relating to the Subcontractor s operations and the details will be kept on record and considered before awarding further work. (f) The Construction Phase Safety, Health and Environmental Plan Subcontractors have a duty to provide information to the Division about the following safety, health and environmental matters:- The risks to safety, health and environment arising from their activities and how they are controlled, including details of any proposed changes to work practices, which might affect approved Method Statements and the Safety, Health and Environmental Plan. Construction/installation activities, which may affect others carrying out future maintenance or alteration/demolition of the building/structure.
Page 6 of 16 (g) Consultation The Group recognises the importance of ensuring that site personnel are able to express their views on health and safety matters and Subcontractors are required to co-operate with the Division to ensure effective lines of communication remain open. Where appropriate, the Division will recognise appointed Safety Representatives and any arrangements for monitoring and discussing health and safety matters at a local level. The Division recognises its duty to ensure that only authorised and suitably qualified persons are allowed on site. The co-operation of Subcontractors is essential to ensure that appropriate checks are made to identify and authorise workers for specific tasks having regard to their skills and experience. Any local arrangements for first aid will be notified at the pre-start meeting and information will be on display about facilities and first aiders. (h) Induction/Safety, Health & Environmental Briefings All operatives/visitors prior to commencing work /visit a site must receive the Barratt Group induction. The Subcontractor must carry out Safety, Health and Environmental Briefings at least one per month. Records of these briefings must be kept. (i) Personal Protective Equipment (PPE) The Subcontractor shall comply with the policy for the wearing of safety helmets, high visibility vests and protective footwear (including mid-sole protection on the footwear) to the current standards. Other PPE appropriate to the work upon which employees are engaged, e.g. eye protection, respirators, gloves and full body harness, shall be provided by the Subcontractor to the appropriate British Standard and training given for use and maintenance. (j) Accident Reporting Subcontractors must report any injury caused by an accident to their employees or Subcontractors to the site management immediately, this is to enable an entry to be made in the Accident Book held on site. In the event of any Injury or Dangerous Occurrence as specified by the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations, the Subcontractor shall report the occurrence to the Incident Contact Centre, or the local office of the Health & Safety Executive (or enforcing authority) using Forms F2508 or F2508A with copies submitted to the site management at the same time. (k) Random Alcohol/Drug Testing The Division reserves the right to randomly test any operative on a site. The acknowledgement slip at the front of this code is required to be signed, so therefore this is notice that the Division is eligible to carry out random tests for alcohol and drugs as the Division may require on any of the operatives. It is the subcontractor s responsibility to inform their employees of this requirement.
Page 7 of 16 (l) Non English Speaking Personnel Contractors must be able to demonstrate how they will discharge their statutory duty to provide understandable information on the risks to health & safety and relevant precautions. Any Contractor who wishes to employ non English speaking nationals must also provide a competent trained person who can communicate / translate the site induction, Safety, Health & Environmental briefings and health & safety information effectively amongst the workforce. All employees expect to be treated fairly and considerately. It is illegal to discriminate against people at work on the grounds of Gender, Race, Disability, Sexual orientation, Religion or belief. The ratio for a bi-lingual supervisor supervising non English speaking operatives is a maximum of 1 to 4 persons, however site management reserve the right to reduce this number for high risk based activities. The supervisor must remain with the operatives at all times in order to communicate/manage their work activities. The following high risk activities may not be undertaken by non English speaking workers:- - Demolition. - Lifting Operations. - Plant Operations. - Any Permit to Work activities. - Lone Working. (m) Welfare Facilities All subcontractors must ensure that the facilities provided are kept in good working order and not misused. Any person found wilfully damaging such facilities would be liable to be removed from site.

Where this is not reasonably practicable the Subcontractor must provide the appropriate mechanical handling devices to eliminate/reduce the need for manual handling. Where manual handling is required, the Subcontractor must make an assessment of the task to be carried out, this must be recorded. The following points must be considered in the assessment: The work task The load to be lifted. The local environment. The capabilities of the individuals. The Subcontractor must ensure that they have given their employees the appropriate training, instruction and supervision to enable them to perform all manual handling operations in a safe manner. The planning of stacking and storage should take into account the reduction or elimination where possible of manual handling operations.
Page 12 of 16 (l) Mobile Phones Mobile phones are prohibited where high-risk activities are being carried out, the high-risk activities are listed below. This list is not exhaustive Erecting/Dismantling Scaffold Operating Plant/Machinery Working in a Confined Space Steel Erection Lifting Operations Banking vehicles (m) Noise Subcontractors are required to make noise assessments where appropriate and submit the results to the Division. Where possible noise levels should be reduced at source by the selection of plant, etc. and where this is not practicable, acoustic screens and suitable hearing protection must be provided, worn correctly and training given. Where the Division designates noise protection zones, Subcontractors must comply with the requirements for hearing protection. (n) Overhead and Underground Services Where work has to be carried out in the vicinity of overhead electricity cables approval is required from the Division following the review of the Subcontractor s proposed Safe System of Work, in consultation with the local Electricity Company. (o) Permits to Work Subcontractors must use the permit system for the following areas of work: - Dig/excavate/pile.

The Subcontractor shall provide all necessary signage and traffic and pedestrian management to Chapter Eight requirements. (r) Work at Heights All work at height must be carried out in such a manner that operatives are protected from falling by some form of physical restraint. Protection must be provided where a person can fall in excess of 1 metre but this may need to be at a lower height for instances work close to water or protruding rebar. The hierarchy of control for prevention of falls whilst undertaking high risk operations are: Evaluate the work to establish if working at height is necessary or if the work can be undertaken from an existing safe structure. Safe working platforms incorporating handrails and toeboards. Use of proprietary fall arrest systems such as Swaledeck and Oxford system for stairwells. Use of mobile elevating working platforms. Passive or collective systems such as safety nets, bean bags or air bags, which require no action by the user to work effectively. Work restraint systems, which include a harness and lanyard, which is adjusted or set to a fixed length that physically prevents the person getting to the place where they could fall. Personal fall arrest system that uses a harness connected to a reliable anchor to arrest and restrict a fall and prevent the user hitting the ground. The anchor point must be above head height where practicable and never below the waist of the operative. The above hierarchy must be applied to all situations and the initial element considered first i.e. safe working platforms should be the first method considered to prevent falls and not beanbags. Each control should be evaluated and only dismissed if it is deemed not reasonably practicable. (s) Scaffolding Where a Subcontractor provides or arranges for the provision of their own scaffolding for the sole use of their employees, the responsibility for ensuring that it is erected in accordance with the requirements identified below, rests with the Subcontractor. Any Subcontractor who utilises a scaffold erected for common use must, prior to use by their employees, inspect the scaffold to ensure that it is safe and suitable for use and immediately report any defects. Co-ordination arrangements for the use of scaffolding will usually be under the direction of the Division.

(t) Aluminium Scaffold Towers Must be erected and dismantled by competent trained, certificated operatives and used in accordance with the Prefabricated Access Suppliers and Manufacturers Association (PASMA) guidelines. The training received from the hire companies or suppliers when delivered to site is not deemed adequate. The training should be provided by a PASMA recognised provider. (u) Steel Erection The Safe System of Work shall specify a working sequence and method of access, which reduces the possibility of falls of persons to an absolute minimum. Tools must be secured in frogs, and fixings, bolts and cleats, etc. must be kept in bags to avoid being dislodged and falling to the ground. The use of MEWP s is preferred. Walking/climbing/shinning steelwork is prohibited on all sites. (v) Transport Drivers must always report to the site office before travelling around the site and must abide by the Divisions Traffic Management Plan s defined access routes and storage areas for the site. Vehicles with high loads must not travel under pipe bridges, overhead mains, etc. unless adequate arrangements have been made to prevent a collision. Vehicles must not travel around site with the body raised. Drivers must have a safety helmet available for use when outside the cab and must wear safety footwear, high visibility vests and any other appropriate protective clothing. Vehicles must be loaded within any appropriate loading restriction and loads must be suitably secured.

Page 16 of 16 SECTION 3 ENVIRONMENTAL ASPECTS (a) CHEMICAL STORAGE, DISCHARGE AND SPILLAGE Only the designated areas marked on the site plan shall be used for the storage of chemicals and oils. These must be clearly labelled and bunded where necessary. Tanks for storage of oil or diesel on site shall conform to the following; Tanks must be of sufficient strength and integrity as to ensure that they are unlikely to burst or leak. Where the container has a storage capacity in excess of 200 litres or more a secondary containment system is used to ensure that leaking or spilt oil does not enter the watercourse. They must be positioned so that they are not vulnerable to impact from vehicles. The secondary containment system i.e. bund must be provided which has the capacity to contain at least 110% of the maximum contents of the tank. The bund walls and floor must be impermeable to water and oil and checked regularly for leaks. A Tank placed upon a skip will not be suitable as a means of containment. Valves and other ancillary equipments must be kept within the bund when not in use. Tanks must not be positioned within 10 metres of any watercourse. Flexible pipes and fittings for filling vehicles etc. must have an automatic valve or tap which closes automatically when not in use. This must not be able to be fixed in the open position. The valve must be locked when not in use and remain inside the bund area. All rainwater accumulating in the bund must be removed. This waste may need to be treated as hazardous particular if contaminated with oil or alternatively filtered first. (b) NOISE, DUST AND VISUAL IMPACT The subcontractors must adhere to noise/dust control zones, where applicable, according to the site-specific rules. The site hours of work and the hours that specific items of equipment are allowed to operate must be adhered to, according to the site-specific rules. (c) PLANTS AND ANIMALS All control measures implemented for the protection of trees and animal species on site must be strictly adhered to. When excavating under/around the canopy of trees or hedges hand digging is only permitted unless under the direct instruction of site management to utilise mechanical means. If a subcontractor suspects they are working in a protected area or near endangered species and this area has not been clearly identified on the site plan or visually signed on site they should report this immediately to the site manager and avoid taking any action that may damage the area. (d) WASTE MANAGEMENT All waste must be deposited in the correct skips, which are clearly marked/labelled. No waste is to be burnt on site. If the contractor is providing their own skip(s) they are responsible for ensuring they comply with the legal requirements for the disposal of that waste. All waste removed from site should be disposed of at a registered waste management facility.
