SWMS for flat roof membrane installation

By SiteSortedBuilt from Safe Work Australia and state regulator guidance · How we write and check theseUpdated

Yes. Flat roof membrane installation usually includes high risk construction work (risk of a person falling more than 2 metres), 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 falling from a roof edge, falling through a floor opening or void, falling through a fragile roof or skylight and fire from hot works.

#Job stepHazardsRisk beforeControlsRisk after
1Set up edge protection around the flat roof and guard any roof openings or skylights
  • Falling from a roof edge
  • Falling through a floor opening or void
  • Falling through a fragile roof or skylight
Extreme
  • Do what you can from the ground or from a scaffold at the gutter line, for example pre-assemble parts on the ground. Eliminate
  • Install edge protection or guardrails on all open roof edges before work starts. Isolate
  • Use a perimeter scaffold with handrails and toe boards along the eaves where practical. Engineering
  • Where guardrails cannot be fitted, use fall restraint on certified roof anchors so workers cannot reach the edge. Engineering
  • Only workers briefed on this SWMS go on the roof. Stop and review the SWMS if the roof, weather or method changes. Administrative
  • Use one safe, controlled access point and keep others off the roof. Administrative
  • Have a written emergency and rescue plan, tested before work starts, for any worker using a harness (WHS Regulations r.80). Administrative
  • Cover every hole and penetration with a fixed, secured cover marked "HOLE" or "DANGER". Isolate
  • Put guardrails with toe boards around stairwells, lift shafts, voids and open edges. Isolate

Hazards to watch on flat roof membrane installation

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

Step 1Falling through a fragile roof or skylightA worker steps on a skylight, clear sheet or old fibre cement roof and falls through to the floor below.
Step 5Burns from hot surfacesTouching hot pipes, tools, bitumen, solder or freshly welded metal burns the skin.
Step 4Flammable liquids and gasesPetrol, solvents, thinners and LPG catch fire or explode when vapour reaches a spark, flame or hot surface.
Step 5Fire and emergenciesA fire, injury or other emergency happens and workers cannot get out, raise the alarm or get first aid in time.
Step 6Sun exposure (UV)Long hours in the sun cause sunburn, eye damage and skin cancer.
Step 5Fire from hot worksSparks and heat from welding, grinding or flame torches set fire to timber, insulation, rubbish or fuel nearby.
Almost certainLikelyPossibleUnlikelyRareHow bad it could be: Insignificant to CatastrophicBA
Highest risk on flat roof membrane installation: Extreme before controls (B), down to Medium after controls (A), on the Australia 5 by 5 risk matrix (likely 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?
  • Will you use a scaffold or mobile tower?
  • Will you use an EWP (scissor lift or boom lift)?

Licences and legal requirements in Australia

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

  • Risk of a person falling more than 2 metres

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

  • Materials hoist: High Risk Work Licence HM for a materials hoist

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 Regulation 2011, Part 4.4 Falls; WHS Regulation 2011, Part 3.2 (falling objects); WHS Regulation 2011, Part 4.2 Hazardous manual tasks; WHS Regulation 2011, Chapter 7 Hazardous chemicals; AS 1674.1 Safety in welding and allied processes (fire precautions); WHS Regulation 2011, regulation 43 (emergency plans).

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 flat roof membrane installation?

Yes. Flat roof membrane installation usually includes high risk construction work (risk of a person falling more than 2 metres), 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 flat roof membrane installation?

Usually Steel cap boots, Safety harness and lanyard, Work gloves, Safety glasses, Half-face respirator (P2 or P3 filters), Sun protection (brim hat, long sleeves, SPF 50+), Hard hat, Hi-vis shirt or vest, Cut-resistant gloves, P2 dust mask, Chemical-resistant gloves (nitrile), Safety goggles, Overalls, Welding gloves, Face shield. The site rules may add more, so check with the principal contractor.
