Risk Rating Risk Rating Activities Possible Safety or Environmental Hazards RB Control Measures to Reduce risk Risk is to be controlled using hierarchy of control measures: 1. Elimination (completely remove from hazard); 2. Substitution (replace the hazard with a lesser hazard); 3. Isolation/ Engineering controls (make a structural change to the work environment or work process) 4. Administration controls (procedures); 5. Personal protective equipment. RA Responsible Officer NOTE: RB = Risk Rating before controls implemented - RA = Risk Rating after controls are implemented. Hazardous substances on site Carrying materials onto site Hazardous materials 3 D H:18 Refrigerant Gases: o Ensure restrained adequately on transport vehicle. o Avoid storing inside cabin of vehicles o Keep minimum quantities o Ensure Material Safety Data Sheet available (within 5 year issue date) o Inspect cylinders regularly to ensure no damage or leaks Take care not to kink copper pipes. Expel air from system as required by manufacturer. Check for refrigerant leakage from pipe connectors. Use appropriate gas detector, or soapy water in a spray bottle. If bubbles form, tighten all fittings and recheck. Ensure adequate ventilation Manual handling injury 3 C M:13 Avoid working in static or awkward postures (such as bending or working with arms raised above head height) for more than 30 minutes at a time and/or 2 hours over entire shift.

Unloading heavy materials Manual handling injury 5 C M:20 Use hand trucks, cable trolleys to move materials Use mechanical aids to lift and hold pipes in position (such as duct lifters) Lift heavy materials as a team All team members must undergo manual handling training Ensure duct lifters have safety gears capable of holding the load in the event of a failure of hoisting rope) Lifting equipment has suitable SWL. Use smaller sized cable drums Slips/ Trips 4 B M:12 Ensure work areas are cleared of off-cuts/ tripping hazards regularly. Traffic management 3 D M:13 Wear high-visibility clothing at all times.

RA Responsible Officer NOTE: RB = Risk Rating before controls implemented - RA = Risk Rating after controls are implemented. Working on roof Working in ceiling spaces Working at heights 5 E E:25 Check type of roof (pitched, tile, skylights etc) Check condition of roof (fragile, brittle etc) Ensure support walls, ceiling and roof have sufficient load bearing capacity. Ensure work area is of the required height. Check the number of persons expected on roof/ceiling space. Ensure scissor lift or step platforms are used. If ladders are only option, ensure they are industrial, good condition, set-up correctly and secured both top and bottom. Where a roof pitch exceeds 35 degrees, do not stand on the roof. Work from a cherry picker, scaffold or travel restraint system. If using travel restraint or fall arrestors, ensure harness and clips are compatible, anchor points have been assessed by qualified persons, training undertaken and emergency plan in place for rescue. Working in ceiling/confined space 3 D H:18 Avoid entering ceiling space work from solid platform. If required to enter, ensure joists/purlins are capable of holding weight of person and equipment and tested for load capacity Don t stand on fragile areas such as plasterboard Walk along planks and crawl if required. Ensure regular rest breaks are taken 2 C M: 9 PSR 1 D M:10 PSR GAW012 SWMS.doc Authorised by: Page 6 of 11

Part 3- RISK ASSESSMENT Risk Management Code of Practice 2007, AS/NZS 31000-2009 Risk Management Principles and guidelines Step 1 Determine What is the possibility that the effect will occur? Almost certain Likely Criteria Expected in most circumstances. Will probably occur in most circumstances. Description Effect is a common result Effect is known to have occurred at this site or it has happened Possible Might occur at some time Effect could occur at the site or I ve heard of it happening Unlikely Rare Could occur at some time May occur only in exceptional circumstances Effect is not likely to occur at the site or I have not heard of it happening Effect is practically impossible. Step 2 Determine - What will be the expected effect? Level of Effect Insignificant/Acceptable Minor Moderate Major Catastrophic Example of each level No effect or so minor that effect is acceptable First aid treatment only; spillage contained at site. Medical treatment; spillage contained but with outside help. Extensive injuries; loss of production Death; toxic release of chemicals Step 3 Determine the risk score A: Insignificant 5: Almost certain B: Minor C: Moderate D: Major E: Catastrophic M11 H16 H20 E23 E25 4: Likely M7 M12 H17 H21 E24 Step 4 Record risk score on worksheet (Note Risk scores have no absolute value and should only be used for comparison and to engender discussion.) Score Extreme: 23-25 High: 14-22 Moderate: 4-13 Action ACT NOW Urgent - do something about the risks immediately. Requires immediate attention. Highest management decision is required urgently. Follow management instructions. 3: Possible M4 M8 M13 H18 H22 2: Unlikely L2 M5 M9 H14 H19 Low: 1-3 OK for now. Record and review regularly, and if any equipment/ people/ materials/ work processes or procedures change. 1: Rare L1 L3 M6 M10 H15 GAW012 SWMS.doc Authorised by: Page 11 of 11
