Fire Inspect Hub is inspection software built for NFPA 33 spray-application and finishing operations. Every checklist item references the NFPA 33 (2024) section it inspects against. Every completed booth inspection generates a professional spray booth inspection report — ready for the client and the AHJ the same day.
Last updated June 2026 — built on the NFPA 33 (2024) edition, with code-referenced checklist items across booth condition, ventilation, fire protection, and combustible-residue housekeeping.

Spray booths and finishing lines are inspected under NFPA 33 — a standard with its own requirements for ventilation interlocks, overspray residue, sprinkler protection, and safety-device testing. None of that maps cleanly onto a generic field-service app or a paper form.
So the inspector ends up hand-building a checklist, remembering which NFPA 33 section each item ties to, and then reformatting everything into a presentable report back at the office. The booth gets inspected once — but documented twice.
NFPA 33 is the Standard for Spray Application Using Flammable or Combustible Materials. It governs the fire-safety condition of spray booths and finishing operations: ventilation, automatic fire protection, combustible-residue housekeeping, safety-device testing, and recordkeeping.
If your customer runs a spray booth or a finishing line, the authority having jurisdiction (AHJ) expects an NFPA 33 inspection record. That covers auto body and collision shops, furniture and cabinet finishing, powder-coating and industrial coating lines, and custom finishing operations — anywhere flammable or combustible coatings are sprayed.
Fire Inspect Hub ships the full NFPA 33 (2024) checklist — six sections, every item code-referenced to its NFPA 33 paragraph. Your inspector works the booth without rebuilding a checklist from scratch.
"No Smoking" signage posted in and around the spray area, and the area kept free of unauthorized ignition sources with hot-work controls in place (§10.12–10.13).
Mechanical ventilation running during and after spraying, spray-to-exhaust interlock, adequate airflow and overspray filters, clean make-up air, duct access, fan condition, and the 25% LFL vapor monitor where recirculation is used (§7.2–7.11).
Automatic protection covering the full area including plenum and ductwork, sprinklers protected from overspray, no painted-over sprinklers, an accessible open control valve, automated fire-system interlock, and an emergency-shutdown station (§9.5–9.6).
A written cleaning threshold and schedule, residue kept within limits, overspray-filter maintenance, end-of-day debris removal, approved bonded-and-grounded waste containers, and airless hose-line condition (§10.3–10.7).
Detection, interlock, and annunciation devices maintained and function-tested at least annually, with the vapor-concentration monitor calibrated and the testing documented (§10.2.1–10.2.6).
ITM records retained for at least three years and the manufacturer's ITM instructions kept on site for the AHJ (§10.2.2, §10.2.7).
NFPA 33 inspection, testing, and maintenance runs at least annually — safety-device function tests (§10.2.4) and vapor-monitor calibration (§10.2.6) are annual minimums.
Daily and operator-established items — enforcing the cleaning threshold, keeping residue within limits, no-smoking enforcement — are operator-responsibility programs your inspector verifies on the annual visit. Fire Inspect Hub captures the annual ITM record and folds those operator checks into the same checklist.
Every deficiency your inspector marks carries a severity and its NFPA 33 section reference — so the report tells the client exactly what's wrong and how serious it is. These are the critical findings booth inspections turn up most:
Painted-over or residue-coated sprinklers — protection can't operate as designed.
Combustible residue accumulated past the established cleaning threshold.
Spray apparatus not interlocked with the exhaust — it can run with the fans off.
Fire-system activation that doesn't shut down spray ops, sound a local alarm, and transmit to the fire alarm.
Missing or non-functional manual emergency-shutdown station.
Class I liquid waste containers not conductive, bonded, and grounded.
Every item cites its NFPA 33 (2024) section, so the AHJ sees exactly what standard each line was inspected against.
Critical or non-critical on every finding, with photos captured in the field and attached to the report.
The suppression standard, the inspector who performed it, the date, and the status — documented on the booth report so the records stay together.
Pass · Non-Critical Deficiency · Critical Deficiency · Impairment — the terminology your AHJ and insurer recognize.
NICET level, state license jurisdiction, and license number render under the inspector's signature on every report.
A branded, client-ready PDF generates the moment the inspection is finalized. No office cleanup, no reformatting.
The booth or item meets the applicable NFPA 33 requirement. No action required.
A deficiency exists but does not have an immediate adverse effect on system performance. Attention needed — not urgent.
A deficiency that adversely affects system performance and requires immediate attention.
Full-stop escalation. The system is out of service. Notify the building owner and AHJ immediately.
The inspector always determines the compliance level. Fire Inspect Hub provides the framework — the professional judgment belongs to the inspector.
Fire Inspect Hub is purpose-built for fire protection contractors who inspect spray booths and finishing operations under NFPA 33 — and for the shops that operate them and need a clean annual record for their AHJ. If you're hand-building booth checklists or reformatting reports after every visit, this was built for you.
