SWMS for ducted air conditioning installation

Yes. Ducted air conditioning installation usually includes high risk construction work (work on or near chemical, fuel or refrigerant lines; work on or near energised electrical installations or services), so a SWMS is required by law before work starts.

It must list the hazards, the controls and how they will be put in place, monitored and reviewed, and the workers must be consulted and sign before starting. The main hazards are disturbing asbestos, electric shock from live wiring, falling through a floor opening or void and heat stress.

Medium
3Lift the indoor unit into the roof with a hoist or team
  • Lifting and carrying heavy loads
  • Falling tools and materials
High
  • Plan to avoid carrying: have materials delivered, and old items picked up, as close as possible to where they are used. Eliminate
  • Use lighter or smaller loads: order smaller bags and shorter lengths, and drain or break down old items before moving them. Substitute
  • Use trolleys, pallet jacks, hoists, vacuum lifters or plant instead of carrying by hand. Engineering
  • Use a two-person lift for anything heavy, long or awkward. Plan the route first and clear it. Administrative

  • Only holders of a refrigerant handling licence (ARCtick) work on refrigerant systems. Administrative
  • Check the licence covers the job: the restricted split licence only covers single-head splits under 18 kW, and adding refrigerant needs an ARC Refrigerant Trading Authorisation (RTA) for the business. Administrative

Pre-start checklist for ducted air conditioning installation

Tick these off before work starts. They come from the hazards, permits and equipment in this job.

  1. Check the roof space for asbestos, cables and access
  2. Work in the roof space early in the day, with breaks and water
  3. Lift the indoor unit into the roof with a hoist or team
  4. Walk on joists or crawl boards only

Hazards to watch on ducted air conditioning installation

The hazards most specific to this job, and the step where each one comes up.

Step 1Tight spaces: roof spaces and under floorsCrawling through roof spaces, under floors or in tight ceilings leads to falls through the ceiling, heat stress, shocks and cuts.
Step 2Confined space entryBad air, toxic gas or engulfment in a tank, pit, sewer or manhole overcomes workers and the people who try to rescue them.
Step 6Refrigerant leaksRefrigerant gas causes frostbite, pushes oxygen out of small rooms, and some types catch fire.
Step 6Pressure testingA pipe, fitting or cap fails under test pressure and blows apart, hitting people nearby.
Step 2Heat stressHard work in hot weather or hot roof spaces causes heat exhaustion or heat stroke, which can kill.
Step 4Falling through a floor opening or voidA worker steps into an open hole, stairwell, lift shaft or penetration and falls to the level below.
Almost certainLikelyPossibleUnlikelyRareHow bad it could be: Insignificant to CatastrophicBA
Highest risk on ducted air conditioning installation: Extreme before controls (B), down to Medium after controls (A), on the Australia 5 by 5 risk matrix (possible and catastrophic becomes unlikely and major).

What changes on your site

This example covers the job itself. Your site may add more. Add controls for any of these that apply (the builder asks you these as yes or no questions):

  • Will anyone work more than 2 metres off the ground?
  • Will anyone use a ladder or stepladder?
  • Will anyone work on a roof?
  • Is there a skylight, clear sheet, fibro or other fragile roofing?
  • Will you use a scaffold or mobile tower?

Licences and legal requirements in Australia

This task can involve these high risk construction work categories under the WHS Regulations:

  • Work on or near chemical, fuel or refrigerant lines
  • Work on or near energised electrical installations or services

Equipment on this job that needs a licence, ticket or training:

  • Crane (Franna or mobile): HRWL for the crane class (e.g. C2, CN, C6), plus Dogging licence (DG) where slinging needs judgement or the load is out of the operator's view

A SWMS must be prepared before any high risk construction work starts. It must list the high risk work, the hazards and risks, the control measures, and how those controls will be put in place, monitored and reviewed. It must be easy for the workers to read and understand.

Rules that apply: WHS Regulations, Chapter 8 (Asbestos); WHS Regulation 2011, Part 4.7 General electrical safety; WHS Regulation 2011, Part 4.3 Confined spaces; WHS Regulation 2011, Part 4.2 Hazardous manual tasks; WHS Regulation 2011, Part 3.2 (falling objects); WHS Regulation 2011, Part 4.4 Falls; Ozone Protection and Synthetic Greenhouse Gas Management Act 1989.

Each state has its own regulator and some extra rules: New South Wales, Victoria, Queensland, Western Australia, South Australia and Australian Capital Territory.

Why SWMS get rejected

Principal contractors send documents back for these reasons. This example avoids them, but check yours too.

  • It is generic: another site address, tasks that are not on this job, or no sign it was reviewed for this site. WorkSafe WA says a generic SWMS may not meet the regulations unless it is reviewed and amended for the workplace.
  • The HRCW boxes are not ticked, or the ticks do not match the tasks (for example a roof job with no falls box ticked).
  • Falls are controlled only by "be careful", training or a harness, with no edge protection or scaffold and no reason why higher controls are not reasonably practicable.
  • Workers will clip on to a harness but there is no rescue plan for someone left hanging.
  • The "how controls are implemented, monitored and reviewed" part is missing, or it says the same thing on every row.
  • No worker sign-on, no person responsible for compliance, or a date given to the principal contractor that is before they actually received it.
  • Licence or White Card details are missing for workers operating plant or doing licensed high risk work.

Questions

Do I need a SWMS for ducted air conditioning installation?

Yes. Ducted air conditioning installation usually includes high risk construction work (work on or near chemical, fuel or refrigerant lines; work on or near energised electrical installations or services), so a SWMS is required by law before work starts.

Who signs the SWMS?

The person conducting the business (PCBU) or their supervisor prepares it with the workers, and every worker doing the high risk work signs to show they were consulted and understand it. Give a copy to the principal contractor before work starts.

How long do I keep it?

Keep this SWMS, and every revised version, until the high risk construction work is finished, where workers and inspectors can see it on site. If a notifiable incident happens during the work, keep it for at least 2 years after the incident.

What PPE is needed for ducted air conditioning installation?

Usually Steel cap boots, Safety glasses, Cut-resistant gloves, P2 dust mask, Safety harness and lanyard, Half-face respirator (P2 or P3 filters), Overalls, Work gloves, Insulated electrical gloves, Arc-rated clothing and face shield, Knee pads, Hard hat, Sun protection (brim hat, long sleeves, SPF 50+), Face shield. The site rules may add more, so check with the principal contractor.
