1 Barricading 1 PURPOSE To protect personnel by preventing or controlling access to hazards in work areas by the installation and maintenance of barricades, demarcation and restricting access. This work practice will provide guidance for the erection of permanent and temporary barricading and demarcation to prevent people from being unnecessarily exposed to a hazard by raising awareness of the presence of a hazard, or restricting access to an area of the workplace. The objective is to ensure that health and safety signs and barricades are placed in an appropriate and consistent manner and to clearly define the demarcation of access ways, storage areas and work areas 2 SCOPE This procedure applies to all Rio Tinto Iron Ore Company of Canada employees, contractors, visitors and work sites, and supports the implementation of the Iron Ore Company of Canada Health, Safety, Environment and Quality (HSEQ) Management System.

2 3 DEFINITIONS Barricade is anything acting to obstruct passage such as barrier tape, cones, railing, temporary fencing / cover, or other barrier intended to limit access to a potentially hazardous area. Barricading is a structure set up across a route of access to obstruct the passage of entry. Caution Zone is an area where a hazard exists and certain health, safety and environment precautions must be met, but personnel aware of the hazard may enter the barricaded area with caution. Danger Zone is an area where there is a definite risk of injury or harm; danger barricading is used to establish a no-go zone where access to the area is prohibited without appropriate authorization. Restricted access areas are locations where potential or actual safety hazards exist and no employee may enter without explicit authorization. This includes demolition areas, abandoned buildings, or areas that have been identified as being potentially unsafe. Demarcation is the setting and marking of an identifiable boundary or limit. Permanent is something which is intended to remain in place without change for an indefinite period of time Soft Barricade is demarcation or barricade consisting of caution or danger tape which may be attached to delineator cones Temporary means remaining in place for a limited period of time. Hazard Cones are cone shaped rubber or thermoplastic markers typically used on roads or footpaths to redirect traffic or to create separation. Page 2 of 9

3 4 BARRICADING MINIMUM REQUIREMENTS 4.1 Identification Where work is to be conducted or a hazard is identified, the requirement for the erection of temporary barricading, demarcation and signage should be determined via completion of a pre-task risk assessment (JHA and/or Take 5). 4.2 Pre task Risk Assessment (JHA and/or Take 5) Prior to erecting permanent and temporary barricading, demarcation and signage, consideration shall be given as to whether the identified hazard can be eliminated, substituted or controlled via engineering means. If the hazard cannot be eliminated, substituted or controlled via engineering means, a barricade area shall be established by way of a Danger zone. If the hazard is non permanent then temporary barricading, demarcation and signage should be used to delineate the hazard area and identify any precautions to be observed through establishment of a Caution zone 4.3 General Requirements Duration of barricading Barricading, demarcation and signage shall remain in place for the length of time that the hazard exists. If the hazard is permanent in nature, permanent barricading, demarcation and signage shall be erected in accordance with the requirements of section 4.5 of this work practice. Temporary barricading, demarcation and signage shall be removed when the hazard no longer exists Barricaded area requirements Barricading, demarcation and signage shall be erected at a sufficient distance away from the hazard to prevent physical contact being made between personnel or equipment and the hazard. The barricaded area must encompass the entire potentially affected area of the hazard, i.e. sparks, falling objects, leaks etc. (take into account the possible deflection of an object from a structure below if it falls) Barricade conditions The barricade shall be maintained in good condition ensuring it remains effective as a control measure. The work area owner is responsible for inspection, monitoring and review of the condition of the barricade. Page 3 of 9

4 4.3.4 Tagging Areas where health and/or safety hazards exist shall be barricaded with an information tag attached at all approaches and displayed on all side and approaches. Information tags shall be conspicuous, readily visible, legible, and display the nature of the hazard and any protective action required. Where overhead work is being conducted, barricades must be erected around the work area to protect others from falling objects. Where entrapment danger exist in an area in which materials may be dropped, dumped or spilled such as debris chutes shall be barricaded and protected by warning signs to prevent the inadvertent entry of workers. A warning system for persons and mobile equipment must be in place surrounding all excavations. The warning system shall consist of barricades, hand or mechanical signals, and flashing lights at night. 4.4 Permanent Barricading Types of permanent barricading Permanent barricades, including platform hole covers, guards and handrails on steps, stairs, elevated walkways and elevated platforms shall constructed by a qualified person and conform with the requirements of Occupational Health and Safety Regulations Guard rails Every open sided floor, working platform, runway, walkway or balcony over 1.22 metres above the existing floor or ground level shall have a guard rail installed that meets the requirements of Occupational Health and Safety Regulations Approval for removal No person shall remove any part of any permanent handrail, mid rail, platform, kick plate or stairway from any site fixed installation without use of the management of change process. 4.5 Demarcation of Permanent Access Ways and Work Areas Design and demarcation of permanent access ways and work areas shall: Follow a clear and logical route and provide access to regularly used facilities Be clear of obstacles such as doors, open windows and other protrusions Keep areas such as electrical distribution boards, fire extinguishers and safety equipment clear. An area of at least one metre in square shall be maintained in front of electrical distribution boards and fire extinguishers Demarcation of access ways and work areas shall meet the following requirements: Access ways and areas that must be left clear are marked with a 75mm/3 inches wide coloured border, with storage areas marked with an additional 75mm inner coloured border. Walkways shall be a minimum of 600mm/ 24 inches wide Page 4 of 9

5 Colour coding of the demarcation shall meet the requirements of OSHA Standards and (f) App A. 4.6 Danger Zone Barricading and Demarcation Danger zones are designated No Go areas and under no circumstances is a person to enter the danger zone unless: They have been authorised to do so by the Supervisor or Authorised person specified on the attached Danger Tag. They are fully aware of the hazard They are wearing the appropriate Personal Protective Equipment as is detailed on the Danger tag Soft or temporary barricading and demarcation shall be used to establish a restricted access zone include, but are not limited to: Work at heights where there is the risk of persons below being affected by falling objects and includes sufficient distance to protect against any falling material that may bounce or ricochet off structures as it falls. Excavation work where personnel and machinery could move too close to the edge of the excavation Crane lifting operations where personnel could walk into the area where loads are being slewed, raised or lowered Blast exclusion areas that are operational will be marked at the entrance of the area. Blast exclusion area roadways on the day of blasts are to be marked by signage at the road entrance which display Danger Blast Zone and a worker in a Light Duty Truck or a piece of mobile equipment will guard and block the entrance way Solid/fixed barricading shall be used to barricade a Danger zone include, but are not limited to: Where the barricading needs to be higher than 1.8 metres / 6 feet or provide a solid fixed barrier Areas where flooring, hand rails, solid fixed barriers or equipment have been removed causing an opening and risk of falling Holes or excavations that are intended to be left in place. Work in manholes. Page 5 of 9
