1 NORTHWEST AIRCONDITIONING SERVICE P/LFill = Green 204 SAFE WORK PROCEDURE Workplace: Page: 1 of 6 TASK / OPERATION: Air Conditioner Installation Overall Risk Rating After Controls 4 Acute 3 High 2 Moderate 1 Low Personal Protective Equipment Fill = Green 204 Foot Hearing High Visibility Head Hand Protective Clothing Breathing Day Operations Normal Requirements: Safety footwear (non-slip boots), hearing protection, high visibility shirt or vest, hard hat and sun protection if required hand protection (gloves), overalls/breathing protection (if required). Safety Notes Fill = Green 204 This SWMS covers risks associated with general installation of air conditioning systems. Ensure the manufacturer s installation manual/guide is available for specific information on all installation works. Main risks: from height - electrocution/electric shock exposure to harmful s (asbestos, silica, refrigerant gases etc) Authorised by Mel Milutin North West Airconditioning Service Page 1- Version 5.0

2 1. Planning Ensure system designed by suitably qualified persons. Assess installation site. Check: - Anchor points (suitable work load and position) - Proximity to power lines - Type of roof (pitched, tile, sky lights etc) - Condition of roof (fragile, brittle etc) - Presence of hazardous materials such as asbestos, lead, silica etc) - Load bearing capacity of support walls, ceiling, roof - Height of work area - Access for equipment and materials - Number of persons expected on roof/ceiling space - Power supply - Location of existing services (heating, water, pipes, electrical leads) - Traffic Management requirements Develop a site and task specific SWMS to control risks. 1L Authorised by Mel Milutin North West Airconditioning Service Page 2- Version 5.0

3 2. Preparation Ensure suitable equipment for job. Examples: - Work at heights: o 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. o Where a roof pitch exceeds 35 degrees, do not stand on the roof. Work from a cherry picker, scaffold or travel restraint system. o 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.

4 2. Preparation - continued - Manual o Use hand trucks, cable trolleys to move materials o Use mechanical aids to lift and hold pipes in position (such as duct lifters) o Ensure duct lifters have safety gears capable of holding the load in the event of a failure of hoisting rope) o Lifting equipment has suitable SWL. o Use smaller sized cable drums - Power Tools: o Guards in place o Electrical leads in good condition and tested/tagged, RCDs in use o Correct for job/used for purpose - Hazardous Materials o If cutting/drilling into structures, determine material type. Provide suitable personal protective equipment for short term works example: o Non-Friable Asbestos: Protective clothing, P1 or P2 half face (can be either disposable or cartridge) o Silica: P1 or 2 half face with particle cartridge Authorised by Mel Milutin North West Airconditioning Service Page 4- Version 5.0

5 3. Pre-operational Inspection Ensure: - Traffic management in place where required - Sufficient Lighting - Suitable weather conditions - Installation manual available and read by all installers - Equipment operational and in good condition - Materials available as required - Electrical leads are not placed in areas where they will pose a tripping hazard or get run over. Authorised by Mel Milutin North West Airconditioning Service Page 5- Version 5.0

6 5. Installation - slips, trips - explosion Legislation breach: - Unlicensed operators Place units/ducting/pipes as specified in design plan. Follow installation instructions for specific model. If changes to design plan are required (eg: changing location of units for ease of maintenance) seek permission from qualified persons. Ensure task/site specific SWMS is followed. Ensure (indoors): - no heating or steam sources nearby - good air circulation - not too near doorways - positioned where vents will not be blocked. Ensure (outdoors): - avoid placing unit in direct sun or under drains etc (if possible) - leave sufficient space between front, rear and sides (as specified by manufacturer) - Keep away from hazardous s or ignition sources - Ensure base and supporting frame is secure and capable of holding unit - Located in area where there is fresh air. Take care not to kink copper pipes. Ensure work areas are cleared of off-cuts/ tripping hazards regularly. Use pipe cutters and cable strippers rather than hacksaws and knives. Authorised by Mel Milutin North West Airconditioning Service Page 6- Version 5.0

7 5. Installation - continued - slips, trips - explosion Avoid putting face too close to work. Stand to side when tightening with pipe wrenches, strip cable away from body. Cover sharp edges of duct. Ensure protective caps are placed into end of thread droppers. When working in ceiling spaces: - avoid entering ceiling space work from solid platform. If required, to enter, ensure joists/purlons 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. Legislation breach: - Unlicensed operators 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. Ensure regular rest breaks taken. Refrigerant Gases: - Ensure restrained adequately on transport. - Avoid storing inside cabin of s - Keep minimum quantities - Ensure Material Safety Data Sheet available (within 5 year issue date) - Inspect cylinders regularly to ensure no damage or leaks - Ensure adequate ventilation Authorised by Mel Milutin North West Airconditioning Service Page 7- Version 5.0

8 7. Installation - continued - slips, trips - explosion Legislation breach: - Unlicensed operators 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. Only undertake work allowed under specific license. Example: - Electrician License required for electrical installations Refrigerant Mechanic with Restricted License cannot perform electrical installation work BUT they can disconnect and connect electrical equipment and replace with like components of the a/c and refrigerant equipment. 8. Emergency Procedures Develop and implement an emergency response plan for the site. Include - assembly points - communication - responsible persons - emergency contacts (including nearest medical facility) - emergency rescue plan (if required) References: OHS Legislation in all States WorkCover SA Safer Industries Industry Guide Safe work at heights Evaporative Air Conditioner Systems 2003 NSW WorkCover Compliance Lessons Learned Compressed Refrigerant Gas Explosion 2008 WorkSafe Victoria Prevention of falls Working on roofs 2005 WorkSafe Victoria Construction Industry Program Incident Wire Duct lifter without safety gear 2002 Authorised by Mel Milutin North West Airconditioning Service Page 8- Version 5.0
