Body Filler / Bog Application & Sanding SWMS
Mixing, application, shaping and sanding of polyester body filler and stopper on vehicle panels, including hardener handling and guide-coat finishing.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Body filler work carries two distinct hazards that need different controls: the wet stage exposes workers to styrene vapour and to organic peroxide hardener that can cause chemical burns and eye damage, while the dry stage generates heavy dust containing respirable crystalline silica and talc. This Safe Work Method Statement covers hardener handling and filler mixing, application and shaping, and final sanding and guide coat — specifying on-tool extraction and P2/P3 respiratory protection for sanding, correct catalyst ratios and hardener segregation for the wet stage, and H-class vacuuming rather than dry sweeping for cleanup.

Applicable Codes of Practice
Primary approved code for this work — booth and mixing-room design, ventilation, RPE selection, isocyanate handling and health-monitoring triggers.
Hazardous chemicals register, SDS, labelling, storage segregation and the risk-management process for paints, hardeners and solvents.
Definitive national guidance on isocyanate sensitisation, air-supplied RPE, exposure standards and respiratory health surveillance.
Applies to compressor, spray gun, air-tool and panel-work noise where the 85 dB(A) LAeq,8h exposure standard may be exceeded.
Ventilation, lighting, eyewash and emergency shower provision, and amenities for workers handling hazardous chemicals.
The hierarchy of control this SWMS is structured around — elimination and substitution before engineering, administration and PPE.
Design, airflow, classification and maintenance requirements for the booth and mixing room this SWMS relies on as its primary engineering control.
Fit-testing, facial-seal and maintenance requirements — the basis for the air-supplied respirator program.
Performance standard the air-fed hood and A2P2 respirators must be certified to.
Dangerous-goods store design, quantities, bunding and separation for paints, thinners and solvents.

Worked example
A shop relied on a workshop-wide extraction fan and dry-swept filler dust at the end of each day, re-suspending the finest and most respirable fraction across the whole workshop — including onto staff who had never touched a sander. Switching to on-tool extraction and an H-class vacuum removed an exposure that was reaching workers well outside the task.

Frequently asked questions
What is the risk with the hardener specifically?
Body filler hardener is an organic peroxide. It causes chemical burns on skin contact and serious eye injury, and it is incompatible with heat and with some other chemicals in the workshop. It should be stored separately, kept sealed and away from heat, and handled with gloves and eye protection — not squeezed out by hand onto a board.
Is this SWMS specific to NSW?
Yes. It cites the Work Health and Safety Act 2011 (NSW), the Work Health and Safety Regulation 2025 (NSW) and SafeWork NSW guidance. The same document is available for every other state and territory — the legislative references are swapped for that jurisdiction.
Do I legally need a SWMS for spray painting in a workshop?
A SWMS is legally mandatory under s. 291 only for high risk construction work. Fixed-workshop spraying is generally not construction work — but you still have a duty under the WHS Regulation to document how you control a hazardous-chemical risk of this severity, and the Spray Painting and Powder Coating Code of Practice is the benchmark you will be measured against. The moment you spray on a construction site, or in a contaminated or flammable atmosphere, the SWMS becomes mandatory.
Is isocyanate health monitoring really compulsory?
Yes, where there is ongoing use of isocyanates and a significant risk of exposure. Isocyanates are listed in Schedule 14 of the WHS Regulation, which triggers the health-monitoring duty — baseline and periodic respiratory function testing and medical assessment by a registered medical practitioner. It is one of the most commonly missed obligations in Australian panel shops.
Will a cartridge respirator do instead of an air-fed hood?
Not for continuous two-pack spraying. Negative-pressure cartridge respirators are not accepted as adequate protection against isocyanate spray mist — the accepted control is an air-supplied (air-fed) respirator. Air monitoring is how you demonstrate that the RPE you have selected is actually adequate for your process.
How do I know if my booth ventilation is good enough?
Airflow should be verified against the booth specification before each shift, the LEV inspected and tested on a documented schedule under AS/NZS 4114, and the whole control set validated with personal air monitoring. A booth that passed its annual service can still fall below specification as filters load between changes.
Can I edit the document?
Yes — it is a fully editable DOCX written as a site-specific template. You complete the company, ABN, site, plant and worker sign-on fields, and adjust the tasks to match your actual process before use.
Who wrote it?
It is authored by an occupational hygiene team led by a Certified Occupational Hygienist (CIH), which is why the exposure, ventilation and monitoring content goes considerably further than a generic template.
