Aerosol / Spot Touch-Up Spraying SWMS
Small-area spot repairs and touch-up using 1K and activated 2K aerosols, including surface preparation and masking, spray application, and aerosol storage and disposal.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Aerosol touch-up is the most underestimated exposure in the trade. Two-pack aerosols now include an activated isocyanate hardener inside the can — chemically the same hazard as booth spraying — yet because the volume is small and the job takes minutes, the work is routinely done in a corner of the workshop with no booth, no extraction and no respirator. This Safe Work Method Statement covers surface preparation and masking for spot repair, aerosol spray application, and aerosol storage and disposal. It takes the position that an activated 2K aerosol is booth-grade work regardless of how little product is sprayed.

Applicable Codes of Practice
Primary approved code for this work — booth and mixing-room design, ventilation, RPE selection, isocyanate handling and health-monitoring triggers.

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.

Worked example
A dealership pre-delivery team used 2K aerosols for chip and scratch repairs at an open bench, several cans a week, with no respiratory protection — on the reasoning that aerosols were "just touch-up". The Safety Data Sheet confirmed an activated polyisocyanate hardener. The work was relocated to an extracted bay with respiratory protection, closing an exposure that had been running unnoticed for years.

Frequently asked questions
Are all aerosol paints 2K?
No — but an increasing number are. A 2K aerosol has a separate hardener that you activate before use, usually by pressing a button in the base of the can, and once activated it has a limited pot life. Check the Safety Data Sheet: if it contains an isocyanate hardener, it needs the same controls as booth spraying regardless of the small volume.
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.
