Paint Booth Fire Suppression.
Authorized installation, inspection, and service for paint booth and spray finishing suppression systems. Solvent vapors and atomized paint are extraordinarily flammable — the system protecting your booth needs to be right, every time.
Paint Booth Suppression
Vapor-Rated.
Code-Compliant.
"A paint booth is one of the highest fire-risk environments in any industrial or collision repair facility. The suppression system isn't a formality — it's the difference between a contained incident and a total loss."
We handle the complete lifecycle of your paint booth suppression system — from initial design and installation through semi-annual inspections, agent recharging, detection component testing, and compliance documentation. Every service is recorded for your insurer, fire marshal, and OSHA records.
Semi-Annual Inspection
NFPA 33 and most AHJ requirements call for inspection every six months. We check the full system — detectors, nozzles, agent supply, actuation components, interlocks, and airflow shutdowns.
System Design & Installation
New booth installation or facility expansion? We design and install Amerex and Pyro-Chem systems engineered for the specific dimensions, airflow configuration, and spray materials used in your operation.
Agent Recharge
After any discharge, we recharge the system, replace detection components, verify all interlocks, and return the booth to full operational status with complete documentation.
Detector & Nozzle Service
Heat detectors and fusible links in a paint booth environment are exposed to solvent vapors and finish overspray. We inspect and replace detection components on the correct service cycle to ensure reliable activation.
Interlock & Airflow Testing
Paint booth suppression systems must shut down the HVAC, exhaust fans, and spray equipment on activation. We verify every interlock fires correctly — a system that doesn't cut airflow can spread a fire faster than it suppresses it.
Compliance Documentation
Full service reports for your fire marshal, insurance carrier, and OSHA records after every inspection. Documentation that satisfies your AHJ, provided every time.
Spray Finishing Expertise
Paint booth suppression requires different agent chemistry and nozzle placement than kitchen or server room systems. We understand the specific hazards of flammable coatings and solvent vapors.
Interlock Verification
Every inspection includes live testing of all interlocks — HVAC shutdowns, exhaust fan cutoffs, and spray equipment disables — to confirm the system responds correctly on activation.
OSHA & Insurance Ready
Paint booth fire suppression documentation is required by OSHA, your insurer, and your local AHJ. We issue compliant records after every service visit.
Any Booth Size
From single-vehicle automotive booths to large-format industrial spray lines, we design and service systems scaled to your exact booth dimensions and production volume.

Your Inspection Schedule.
NFPA 33 governs spray application of flammable materials and sets the inspection requirements for paint booth suppression systems. Here's how the service cycle works.
Operator Check
Done by facility staff. Confirm the system pressure gauge is in range, pull station is accessible, no nozzles are visibly obstructed by overspray buildup, and the system tag is current.
Full Inspection
Heiman comes on-site. Complete system inspection including detector condition, nozzle check, agent supply verification, actuation test, and all interlock and airflow shutdown testing. Full documentation issued.
Full Recharge
After any discharge — accidental or fire event — the system must be completely recharged, all detectors and links replaced, and all interlocks re-tested before the booth returns to service.
Booth Modifications
Any change to booth size, airflow, or spray equipment configuration requires a suppression system re-evaluation. Adding a new spray line or extending a booth without updating the system creates a coverage gap.
Why Paint Booths Fail Inspection.
Fire marshals and insurance inspectors find the same violations in spray finishing operations. Here's what gets facilities cited — or shut down.
Nozzles Clogged With Overspray
Paint overspray accumulates inside suppression nozzles over time, restricting or completely blocking the discharge pattern. A clogged nozzle may not distribute agent effectively during a fire — this is one of the most common paint booth suppression failures inspectors find.
Overdue or Missing Inspection Tag
No current inspection tag is an automatic citation. Paint booth suppression systems are a specific line item on fire marshal and insurance inspection checklists. An expired tag often triggers a formal notice of violation and a deadline to comply or cease operations.
Interlocks Not Functioning
The suppression system must shut down airflow — exhaust fans, makeup air units, and spray equipment — when it activates. If interlocks have been disconnected, bypassed, or have failed, the system will discharge into a live airstream that can carry fire through the ductwork.
System Not Designed for Current Materials
Switching from solvent-based to waterborne coatings — or vice versa — can affect the suppression system's agent selection and nozzle configuration requirements. A system designed for one coating chemistry may not perform as expected with a different product line.
Booth Modifications Without System Update
Extending a booth, adding a spray station, or modifying the ventilation layout without updating the suppression system is a common citation — and a genuine hazard. Coverage gaps left by physical changes to the booth may leave entire areas unprotected.
Who Needs a Paint Booth Suppression System?
NFPA 33 requires fire suppression in spray application areas where flammable or combustible liquids are applied. If atomized flammable material is being sprayed in an enclosed or semi-enclosed space, a suppression system is required. Here's who we serve.
Auto Body & Collision Repair
Collision repair facilities with enclosed spray booths are the most common users of paint booth suppression systems. Any booth used for vehicle priming, base coat, or clear coat application requires a compliant system.
Custom & Production Painting
Custom vehicle painters, motorcycle shops, and production coating facilities — any operation with an enclosed spray area and flammable coatings needs a suppression system sized to the booth.
Industrial Finishing Lines
Manufacturing facilities with spray finishing lines for metal, wood, or plastic components require suppression systems designed for the specific coating materials, volumes, and booth configurations in use.
Woodworking & Cabinet Shops
Shops applying lacquer, varnish, stain, or solvent-based finishes in an enclosed spray area fall under NFPA 33. Wood dust combined with solvent vapors creates a particularly high fire risk.
Powder Coating Operations
While powder coating uses no solvents, the curing oven and adjacent spray areas may still require suppression depending on AHJ interpretation and facility configuration. Contact us to clarify your specific requirements.
They're fundamentally different systems designed for different hazards. Kitchen systems use wet chemical agent to suppress grease fires and cool cooking surfaces. Paint booth systems typically use dry chemical agent or clean agent formulations designed to suppress flammable vapor fires and not re-ignite. The detection methods, nozzle designs, and agent chemistry are specific to each application — a kitchen system cannot substitute for a paint booth system, and vice versa.
Potentially, yes. Waterborne coatings have different flash points and combustion characteristics than solvent-based products. In some cases the suppression system's agent type or nozzle configuration may need to be updated to match the new materials. We recommend scheduling an evaluation any time you make a significant change to your coating product line — your insurer and fire marshal may require documentation of the change as well.
Nozzle condition is assessed at every semi-annual inspection. In high-production spray environments, overspray accumulation can clog nozzles faster than the six-month cycle. We recommend your staff do a visual check monthly — if a nozzle cap is missing or you can see paint buildup around the nozzle opening, call us before the next scheduled inspection. Clogged nozzles are one of the most common reasons paint booth systems fail to suppress effectively.
Yes. We commonly perform incoming assessments on paint booth suppression systems for new facility owners or tenants. We'll evaluate the existing system, identify any deficiencies, confirm it's appropriately sized for your current operations, and bring it into compliant status with documentation. Don't assume a system left by a previous tenant is current — verify it before your first inspection visit from the fire marshal.
The booth cannot return to service until the suppression system is fully recharged, all detection components are replaced, all interlocks are re-tested, and a service report is issued. Dry chemical discharge also requires thorough cleanup of the booth interior — the agent residue must be removed before spray operations resume or it will contaminate finishes. We handle the suppression system side; your booth vendor or facility team handles the cleanup.
Most commercial property insurers require proof of current semi-annual suppression inspection for paint booth operations. Some carriers specify the credentials of the servicing technician and the brands of system they'll accept. We provide a complete service report after every inspection documenting the system type, components serviced, test results, and date of service. If your carrier has a specific form, let us know and we'll work with it.
