Spray booths are at the heart of every panel beating and smash repair operation in New Zealand. They're also among the most fire-prone environments in the entire commercial property sector. Paint solvents, thinners, and base coats are highly flammable, and ignition — from a static spark, a nearby heat source, or spontaneous chemical reaction — can cause catastrophic losses in seconds.
For panel beaters, understanding how spray booth risk affects your insurance — and what conditions your insurer may impose — can be the difference between a fully covered claim and a dispute.
Why Spray Booths Are a High-Risk Insurance Category
Insurers assess spray booth operations in a special category for several reasons:
Flammable material volume: Modern spray booths use solvent-borne, water-borne and UV paints. Even water-borne paints contain flammable solvents. A fully stocked mixing room contains hundreds of litres of flammable product.
Ignition sources: Spray guns, electrical equipment in the booth, static electricity from spray application, and nearby hot work (welding, grinding) all create ignition risk.
Fire spread: A spray booth fire can spread to the adjoining workshop in minutes. Customer vehicles, tools, equipment and the building structure are all at risk.
After-hours risk: Many spray booth fires occur after hours, when no one is present to respond.
Insurance Conditions for Spray Booth Operations
Insurers typically impose specific conditions on panel beating businesses with spray booths. Failing to meet these conditions can result in a claim being declined. Common conditions include:
Construction requirements: Spray booths should be of fire-resistant construction, complying with NZ fire codes (NZS 4303 or equivalent). Improper construction is a major reason for declined claims.
Ventilation: Adequate forced ventilation to prevent solvent vapour accumulation is typically required. Blocked or inadequate ventilation voids many policies.
Fire suppression: Many insurers require automatic fire suppression systems in spray booths. Manual extinguisher provision may be insufficient for some underwriters.
Chemical storage: Flammable materials must be stored in fire-rated cabinets or separate fire-rated rooms. Bulk storage in the general workshop area is commonly excluded.
Hot work controls: A formal hot work permit system — preventing welding, grinding or cutting within a defined distance of the spray booth — is often required.
Electrical compliance: Regular electrical inspections of the booth's extraction fans, lighting and electrical fittings are commonly required.
Disclosing Your Spray Booth to Your Insurer
Non-disclosure of a spray booth at the time of policy inception is a significant error. If you operate a spray booth and your insurer doesn't know, your entire property policy may be voidable.

What to Do After a Spray Booth Fire
If you experience a spray booth fire:
1. Ensure everyone is safe and call 111
2. Do not enter the building until the fire service gives the all-clear
3. Contact your insurer immediately — do not wait until business hours
4. Preserve evidence — do not move debris or equipment without insurer approval
5. Document everything you can safely photograph
Prompt notification is required under most policies. Delayed reporting can complicate your claim.
Getting the Right Coverage
Panel beaters need a specialist motor trade policy that explicitly covers:
A standard commercial property policy may not adequately address spray booth risk. Ensure your broker has experience with panel beating operations and can confirm your coverage in writing.
