Food truck fire inspection checklist: what the fire marshal checks
A food truck fire inspection checklist covering hood tags, propane mounts and extinguishers, plus what a failed inspection actually costs you.
What to take away
- The fire marshal checks three systems on a food truck: cooking ventilation and hood suppression, propane storage and connections, and portable extinguishers with current tags.
- Most US jurisdictions adopt NFPA 1, NFPA 96 and NFPA 58, then amend them locally, so the tag dates and mount heights that pass in one city may fail in the next.
- A failed inspection usually means a red tag, an immediate stop on cooking, and a re-inspection fee before you can reopen.
- Keep the hood suppression tag, extinguisher tags, and propane leak test record in the truck, not at home.
Who inspects a food truck and under what code
Fire marshals work for the local fire department, not the health department. Health inspectors look at food temperature and handwashing. Fire inspectors look at ignition sources, suppression and gas.
The base documents are the NFPA 1 Fire Code for general fire safety and the NFPA 96 standard for commercial cooking ventilation for hoods and suppression. Propane falls under the NFPA 58 Liquefied Petroleum Gas Code.
Cities amend all three. Chicago and Houston both run their own fire prevention codes on top of the model text, and a truck built for one market often needs changes before it clears the other. That is why the checklist below is written as items to verify against your local code, not as a universal pass list.
Hood and suppression system checks
The marshal will ask to see the hood, the duct, the suppression cylinder and the manual pull station. Expect these points.
- Hood suppression tag shows a current inspection date, usually within six months, with the servicing company name and technician license number.
- Nozzles are capped, aimed at the cooking surface, and free of grease buildup.
- Manual pull station is accessible, labeled, and not blocked by shelving or a generator.
- Fuel shutoff for the cooking appliance trips when the suppression system discharges.
- Duct and hood filters are clean enough that grease is not running down the metal.
A missing or expired tag is the single most common failure point on a used truck. If you buy a truck with no suppression paperwork, budget for a full recertification before your first inspection.
Propane inspection requirements
Propane is where inspectors spend the most time, because a leak inside an enclosed truck is the worst outcome on the list. The fire inspection overview covers the general categories, but the specifics come from NFPA 58 and your local amendments.
- Cylinders are mounted outside the cooking compartment, secured against movement, and upright.
- Cylinders are within their requalification date, stamped on the collar.
- Hoses are rated for LP gas, free of cracks, and not routed through doorways or over hot surfaces.
- A leak test has been done recently, and the regulator and connections show no bubbles under soap solution.
- A carbon monoxide alarm is installed and working in any enclosed cooking area.
Inspectors in cold markets also check that cylinders are not stored inside the truck overnight. That is a storage violation in many cities even when the truck itself passes.
Extinguishers, egress and electrical
These items are quick to check and quick to fail.
| Item | What the marshal looks for |
|---|---|
| Class K extinguisher | Mounted within reach of the cooking appliance, tagged, charged |
| Class ABC extinguisher | Mounted near the exit, tagged, charged |
| Exit | Door opens freely from inside, no padlock or chain |
| Wiring | No exposed conductors, no household extension cords |
| Generator | Separated from cooking surfaces, fuel stored away from ignition |
Example: a failed inspection in practice
A truck passes its health inspection, then fails fire because the hood tag is eight months old and the pull station is behind a stack of fry boxes. The marshal issues a red tag and prohibits cooking until the system is recertified and re-inspected. The owner cannot serve hot food at a booked event, loses the deposit, and pays a re-inspection fee plus the suppression company's emergency call-out rate. That sequence is routine, and it is entirely avoidable with a tag check before the season starts.
What happens if you skip it
The consequence is not a warning letter. A red tag stops cooking on the spot, and in most cities the truck cannot operate until a re-inspection passes. Re-inspection fees are common, and some departments charge for the second and third visit.
Beyond the fee, you lose booked service days. A single failed inspection during a festival week can cost more than the annual suppression service contract. Repeat violations can also put your operating permit at risk, which is the same pressure that drives the appeal process for a denied permit in cities that treat fire clearance as a condition of the vending license.
Keep a binder in the truck with the suppression tag, extinguisher tags, propane leak test record, and the last inspection report. If you operate in more than one city, track each jurisdiction's amendment separately, because your commissary arrangement may also be inspected by the fire department rather than the health unit.
Common questions
How often does the hood suppression system need inspection?
Most US jurisdictions require semiannual service, so the tag is good for about six months. Some cities require quarterly service on high-volume cooking. Check your local fire prevention code, not the sticker from the last company.
Can I pass with a portable propane cylinder inside the truck?
Usually no for cooking. NFPA 58 and most local amendments require cylinders outside the cooking compartment, secured and upright. Small cylinders used for a single appliance may be allowed under local rules, but the marshal decides on site.
What does a failed fire inspection cost?
Expect a re-inspection fee, an emergency suppression service call, and lost service days. Fees vary by city, so treat any figure as local and confirm it with your fire department before the season.
Do I need a fire inspection if I only serve cold food?
If there is no cooking, there may be no hood suppression requirement, but extinguishers and egress still apply. Ask the fire marshal in writing, because the answer changes with the menu.
