When accessing the cabin, three points of contact shall be maintained at all times Version Page 5 of 9 Printed 21/05/2015-15:40

4. If a platform is to be used to gain access to the operator s cabin it must be fitted with edge protection Inspection Of Equipment 1. All height safety equipment used on site must be inspected on a regular basis, and also by the equipment user before each use 2. Inspection intervals should be in accordance with the manufacturer s specifications or at periods not exceeding six months 3. Inspections must be conducted by a competent trained person, and records of inspection must be maintained 4. Guidance on the inspection of fall-arrest systems and devices must be conducted in accordance with Australian Standards 8.2 Fall Prevention Systems (Manager/Supervisor, Equipment User) Physical Barriers Physical barriers are the preferred method of preventing a person from falling from height. Other measures will not always prevent the person from being injured. For example, a fall-arrest system may prevent a person from falling onto another surface but the person may still suffer an injury as a result of the load placed on their body by the fall arrest harness. Or, a person may lose their balance and fall from a working platform and be caught by a catch net. However, because the fall was unexpected the person may suffer an injury through landing in the catch net awkwardly. Examples of physical barriers include: Edge protection systems Fall protection covers Working platforms Edge protection systems are barriers erected around the edge of a building, structure or hole. An edge protection system may consist of guard railing or vertical containment sheeting. Guard rail systems should be used on the edge of working platforms, walkways, stairways, ramps and landings. A guard rail should run parallel to the working surface and not be further than 100mm outside the edge of the working surface. The guardrail height should be between 900mm and 1100mm above the working surface. Guard rails must have mid rails. A mid rail is a structural member secured 600mm between the guardrail and the working surface. It should run parallel to the working surface and be no further than 100mm outside the edge of the working surface. Both the guard rail and the mid rail should be able to withstand the impact of a person falling against them. A toe board is a vertical barrier used in conjunction with guard rails and mid rails to prevent a person from falling under the guard rail. Toe boards may be fully sheeted with timber or metal or made from mesh. They should be secured adjacent to the work surface and extend a minimum of 150mm above the work surface. Personal Fall Protection Systems of work and equipment that secure a person to a building or structure are known as personal fall protection. Personal fall protection systems discussed in this procedure include travel restriction Version Page 6 of 9 Printed 21/05/2015-15:40

devices, fall prevention systems and fall arrest systems. Use personal fall protection systems: When working within the confines of a working platform When other forms of fall protection such as guardrails are not available In conjunction with other measures of fall protection such as safety nets or fixed platforms The use of these systems requires active involvement to ensure the equipment is worn, attached and used in the correct way. Where no other form of fall protection can be applied, personal fall protection systems should be used to minimise the risk of a person from falling from a height (travel restriction devices) or injury to a person after a person has fallen from a height. Travel Restriction Devices A travel restriction device restrains a person from reaching an unprotected edge by tethering them to an eye-bolt or other suitable anchorage point. This type of personal fall protection system is preferred over those that arrest a person after they have fallen. The anchorage points should be capable of taking the load. Personal fall protection devices which restrict travel include industrial rope access systems and fall-prevention systems. An industrial rope access system is a twin rope system used to provide access to a work area. A work positioning harness or seat is attached to one rope and a fall arrest harness is attached to the other rope. The system should be used in accordance with the designer s and/or the manufacturer s instructions. Fall Prevention Systems Fall prevention systems consist of a restraint belt or work positioning harness connected to a restraint line which in turn is attached to a fall-prevention static line or an anchorage point, and prevents a person getting into a situation where they could fall. Types of fall-prevention systems include a restraint belt or work positioning harness. When worn by a person connected to a restraint line, the horizontal distance the wearer is able to travel is restricted. A fall-prevention static line is a horizontal line connected to a fixed anchorage point to which a restraint line is attached to increase the area that can be covered by a person wearing a fallprevention system. A fall-prevention anchorage point is a secure point of attachment to a structure or static line to which a restraint line is attached. An anchorage point of a fall prevention system should be positioned to ensure that the restraint line does not allow the person wearing the system to free fall. Fall Arrest Systems Fall arrest systems are designed to arrest the fall of a person. Types of fall arrest systems include: A fall arrest harness connected to a lanyard assembly that is attached to a fall arrest static line or an anchorage point (where there is a risk of free fall); or A ladder belt connected to a lanyard of not more than 300 mm in length attached to a ladder fallarrest device (where there is a risk of a free fall of not more than 600 mm) An important factor in the safe use of a fall-arrest system is to reduce the free fall distance as far as possible. Correctly installed fall-arrest equipment will only safely arrest a fall if there are no obstructions in the fall path. The longer the free fall distance, the greater the risk of a person hitting an obstruction. Before a fall arrest system is used, the work area should be inspected to ensure there are no obstructions in the potential fall path. Any obstruction should be removed from the fall path area. Immediate action should be taken to retrieve persons from fall arrest systems. Version Page 7 of 9 Printed 21/05/2015-15:40

8.3 Work At Height Rescue Plan (Manager/Supervisor, Equipment Operator/User) A person suspended in a harness can quickly suffer loss of consciousness caused by blood flow to the lower extremities of the body due to the effect of gravity. This can result in death if the person is not rescued from this situation between 5 and 10 minutes after the initial fall. Use of a rescue harness with foot straps or a sling strap to tie off to the harness will increase the time a conscious person can remain conscious by enabling the person to support their feet while waiting rescue. An unconscious person will need urgent removal from a suspended position as they will not have the ability to maintain blood flow to their extremities via movement or use of foot straps. Possible situations where personnel may fall and potential rescue methods include: 1. Handrail collapse while erecting, modifying or dismantling: Use EWP to retrieve person(s) from scaffold; or Use platform ladder to retrieve person(s) from scaffold. 2. Person suspended in harness after falling from bridge: Use EWP to retrieve person from suspended position; or Use platform ladder to retrieve person from suspended position; or Use rope rescue techniques to retrieve person from suspended position. 3. Person in the process of erecting or dismantling handrails falls and is suspended in harness: Use platform ladder to retrieve person from suspended position; or Use EWP to retrieve person from suspended position. 8.4 Construction Work (Manager/Supervisor) 1. Construction work such as bridge construction, must not be performed where there is a risk of a person falling more than two metres unless a safe work method statement (SWMS) is prepared before the work commences, and the work is performed in accordance with the statement 2. A SWMS is designed to be developed after, or in conjunction with, a risk assessment. The SWMS must be completed before risk control measures are put in place. Roles And Responsibilities Managers and supervisors must ensure: 1. Compliance with the Safe Work Procedure 2. A Job Safety Plan (JSP) is undertaken and control measures implemented to eliminate or reduce fall risks as far as practicable 3. That staff are trained in fall prevention systems and JSP training 4. Equipment used to control the risk of fall is designed and constructed for the task and the working environment in which it is to be used Version Page 8 of 9 Printed 21/05/2015-15:40

5. Emergency procedures are established to enable the rescue of an employee in the event of a fall occurring, and the provision of first aid as soon as possible after the emergency occurs 6. Report any incidents, hazards, near misses or faulty equipment Employees must: 1. Carry out tasks in accordance with information, instruction and training given and use any risk control measures put in place or provided by the employer 2. Ensure a working at heights permit is completed when required 3. Report any incidents, hazards, near misses or faulty equipment Revision History Topic No Topic Name Owner SWP-043 Working at Heights Safety Manager Last Review Review Period (Yrs) Next Review Revision Ver Date vnn.n dd/mm/yyyy vnn.n - 01/06/2015 Amendment Detail Revision details Author.
