Colour Matching, Tinting & Paint Mixing Room SWMS
Receipt and dangerous-goods storage of paint stock, colour matching, tinting, weighing and decanting within a dedicated paint mixing room, and spray-out card verification.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
The mixing room concentrates the workshop's entire chemical inventory into one small space, and the person who works there is exposed for far longer each day than any individual sprayer. Cumulative solvent vapour across a shift, repeated dermal contact while decanting, and static ignition risk in a flammable atmosphere are the defining hazards. This Safe Work Method Statement covers stock receipt and dangerous-goods storage, colour matching, tinting, weighing and decanting, and spray-out verification — built around the AS/NZS 4114 requirement that the room has dedicated local exhaust ventilation running whenever it is occupied, and bonded, earthed dispensing to remove the static ignition path.

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.

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.

Worked example
A shop's mixing room extraction was wired to the light switch and routinely left off during short jobs. Because mixing happens dozens of times a day in short bursts, the cumulative daily exposure of the mixer exceeded that of the sprayers, who at least wore air-fed hoods. Interlocking the ventilation so it runs whenever the room is occupied fixed the highest personal exposure in the business.

Frequently asked questions
Our mixer never sprays — why do they need protection?
Because exposure is about time as well as concentration. Mixing happens in short bursts many times a day, and the mixing room concentrates vapour from the entire inventory. Cumulative daily exposure for a mixer frequently exceeds that of a sprayer, who at least wears an air-fed hood inside an extracted booth.
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.
