Welding — Auto Body SWMS

Welding in auto body workshops involves MIG, spot, and occasionally gas welding on panels that are coated, galvanised, or painted, generating toxic metal fumes containing zinc, manganese, and chromium compounds. The confined workshop environment concentrates fume exposure far more rapidly than open-air welding operations. Welding fume is now classified as IARC Group 1 carcinogenic to humans, and welding fume exposure limits were tightened in November 2025. This template covers all auto body welding operations with controls mapped to the binding Welding Processes Code of Practice effective 1 July 2026.

Controls (Hierarchy of Controls)

Provide local exhaust ventilation (extraction arm or on-gun extraction) positioned within 300 mm of weld zone
Remove all coatings, paint, and galvanising from weld area before welding to eliminate toxic fume sources
Provide P2 respiratory protection minimum for all auto body welding tasks
Maintain minimum 3-metre fire-free zone around welding operations with fire extinguisher and fire blanket
Require welding helmet with minimum shade 10 filter and full-body welding PPE
Inspect welding equipment daily including earth clamp, cable insulation, and gas connections
Assign fire watch for 30 minutes after hot work completion near combustible materials

Recent Prosecutions

SafeWork NSW v Workshop Operator$95,000

Worker suffered metal fume fever after MIG welding galvanised panels without fume extraction or RPE. Workshop had no welding fume controls despite daily welding operations.
