Hot Works (Cutting, Welding, Brazing) SWMS Templates

Welding and hot work are not automatically listed as High-Risk Construction Work under WHS Regulation 2025 Schedule 3, but a SWMS is still required when hot work is performed in or near a confined space, at heights above two metres, on energised electrical installations, or where there is a risk of fire or explosion. Most commercial sites also require a SWMS as a contractor pre-qualification condition, and AS 1674.1 mandates a documented hot-works permit before ignition sources are introduced.

Yes — welding fume was reclassified by IARC as a Group 1 human carcinogen, and Safe Work Australia has tightened the workplace exposure standard. A fume-specific SWMS documents local exhaust ventilation, on-tool extraction, respiratory protection selection under AS/NZS 1715 and 1716, and health surveillance under WHS Regulation 2025 Schedule 14. Different base metals (stainless, galvanised, aluminium, cobalt alloys) generate different hazards, so most PCBUs maintain a parent welding SWMS plus material-specific fume addenda.

Under AS 1674.1, a hot-works permit must identify the work location, the personnel authorised, the duration and expiry of the permit, the combustibles within a 15-metre radius, fire watch arrangements during work and for at least 60 minutes afterward, available extinguishers, atmospheric testing where flammable vapours may be present, and isolation of fuel sources. The permit must be signed by an authorised issuer and displayed at the work area while hot work is underway.

The model WHS Regulation 2025 is adopted across all jurisdictions except Victoria, which operates under the OHS Act 2004 and OHS Regulations 2017. Victorian SWMS must reference Victorian equivalents and Worksafe Victoria compliance codes. Western Australia, NSW, Queensland, SA, Tasmania, ACT and NT use harmonised WHS Regulations. A well-structured hot-works SWMS cites both the model regulation and AS 1674, then notes the relevant jurisdictional regulator, so a single template can serve nationally with minor jurisdictional headers.

A SWMS is a project-level document prepared by the PCBU performing the work, identifying hazards, risk controls, training and consultation under WHS Regulation 2025 sections 299–303. A hot-works permit is a site-specific, time-limited authorisation issued by the site controller under AS 1674.1 immediately before ignition sources are introduced. The SWMS sets out how hot work will be controlled generally; the permit confirms that those controls are in place for this specific area, today, for this defined window.
