Auto-Body Grinding & Sanding SWMS
Power grinding and sanding of auto-body panels. Covers angle-grinder, dual-action sander, orbital sander, vibration exposure, dust extraction, eye protection.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Auto-body grinding and sanding involves the use of angle grinders, dual-action sanders and orbital sanders to remove paint, filler, weld spatter and corrosion from vehicle panels in preparation for repair or refinishing. The work generates respirable crystalline silica and metal dust, projects high-velocity particles, transmits hand-arm vibration through prolonged tool contact, and produces sparks capable of igniting solvent vapours common in a panel shop. Under WHS Regulation 2025, a Safe Work Method Statement is mandatory where the work is classified as high-risk construction work or where hazardous chemical exposure and vibration exposure standards apply. This SWMS documents the hazards, risk controls and supervisory arrangements required before any abrasive panel work commences, satisfying the PCBU's duty under s19 of the WHS Act and the consultation duties under s47. It provides a defensible record for regulator inspection and pre-start verification.
Hazards identified
7 hazards covered, sorted by priority.
Hand-arm vibration syndrome, vibration white finger and permanent peripheral nerve damage with loss of grip and tactile sensitivity
Silicosis, accelerated lung function decline, occupational asthma and notifiable disease reporting under WHS Reg 675
Penetrating eye injury, corneal abrasion, facial laceration and permanent vision loss requiring surgical intervention
Flash fire, vehicle fuel tank ignition and partial workshop loss with potential fatal burns to operators
Noise-induced hearing loss, tinnitus and breach of exposure standard under WHS Reg 56 requiring audiometric monitoring
Fragmentation injury to torso, neck and femoral artery causing severe blood loss and potential fatality
Acute lumbar strain, chronic shoulder rotator cuff injury and workers compensation claims requiring extended return-to-work programs
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Use chemical paint stripper or media blasting where feasible to remove the need for prolonged mechanical grinding on large panel areas.
- 2Elimination — Replace severely corroded panels with new pressed sections rather than grinding back parent metal to sound substrate.
- 3Substitution — Switch from angle grinder to dual-action sander with ceramic abrasive on filler work to reduce vibration magnitude and dust load.
- 4Substitution — Use low-vibration tools tested to AS 2763 with declared a(hv) values below 2.5 m/s² where the task permits equivalent productivity.
- 5Engineering — Connect every sander and grinder to an M-class or H-class vacuum extractor with HEPA filtration directly at the tool shroud.
- 6Engineering — Install local exhaust ventilation at the prep bay with face velocity verified quarterly and isolate the bay from refinishing booths.
- 7Administrative — Limit continuous trigger time to 20 minutes per hour and rotate operators to keep daily A(8) vibration exposure below 2.5 m/s².
- 8Administrative — Conduct pre-start tool inspection, verify disc RPM rating against tool speed, and brief all operators using this SWMS before work begins.
- 9PPE — Wear P2 half-face respirator (or PAPR for extended work), AS/NZS 1337.1 medium-impact wide-vision goggles plus face shield, and Class 5 hearing protection.
- 10PPE — Use anti-vibration gloves to AS/NZS 2161.3, flame-resistant cotton overalls, and steel-cap safety footwear with metatarsal protection for the entire task.
Applicable Codes of Practice
Sets the 85 dB(A) eight-hour exposure standard and 140 dB(C) peak limit that grinding on sheet metal routinely breaches, triggering audiometric testing.
Mandates fit-testing, cartridge selection and maintenance regime for the P2 and PAPR respirators required when grinding filler and primer.
Body filler contains crystalline silica; the code requires exposure assessment, on-tool extraction and health monitoring under WHS Reg 529CA.
Specifies medium-impact rating required for grinding operations; standard safety glasses are non-compliant for projected particle hazards.
High-Risk Construction Work triggered
Grinding and sanding of body filler, primer and galvanised steel releases respirable crystalline silica, zinc oxide fume and metallic particulates above the workplace exposure standard.
Sparks from abrasive grinding within a panel shop containing solvents, paint thinners, fibreglass resin and vehicle fuel systems constitutes ignition-source hot work.
PCBU must prepare, consult workers on, and retain this SWMS for two years (or duration of any notifiable incident investigation). Penalties for non-compliance are substantial and indexed; current maximum follows the prevailing WHS schedule for Category 1 and 2 offences.

Worked example
At a suburban collision repair centre, a third-year apprentice is assigned to grind back filler on the rear quarter panel of a sedan ahead of primer application. Before starting, the workshop supervisor opens this SWMS at the prep bay pre-start board and walks the apprentice and a second-year through each hazard line. The supervisor confirms the dual-action sander is connected to the M-class extractor, checks the abrasive disc RPM rating matches the tool, and verifies the apprentice has completed P2 respirator fit-testing within the last twelve months. Both workers sign on against the controls, noting the 20-minute trigger-time limit and the rotation schedule pinned beside the bay. Mid-task, the apprentice transitions to an angle grinder to remove weld spatter near the wheel arch — the supervisor pauses the work, returns to the SWMS, and confirms the hot-work control requires solvent containers to be removed from the bay and a fire extinguisher staged within three metres. The control is implemented before grinding resumes. At end of shift, the SWMS sign-on sheet is filed with the job card, providing a defensible record should the regulator audit dust exposure or vibration exposure for that vehicle repair.
