“Fire Extinguisher Code Compliance Inspections (Requirements)”
Portable fire extinguishers must be inspected regularly to meet OSHA and NFPA 10 requirements and to ensure they work when needed. This guide explains monthly visual extinguisher checks, annual maintenance, documentation, and when a separate fire watch is required if fire protection is impaired.
Compliance at a Glance
- Monthly visual inspection: Quick in‑place check by the employer or designated staff to verify each portable extinguisher is present, accessible, undamaged, and appears fully charged.
- Annual maintenance: Detailed examination by a trained person or licensed extinguisher service company, with repairs, recharging, or replacement as needed per NFPA 10 and OSHA.
What Counts As A Code‑Compliance Fire Extinguisher Inspection?
A code‑compliance extinguisher inspection program covers both monthly visual inspections and annual maintenance checks for all portable fire extinguishers in the workplace. OSHA 29 CFR 1910.157 requires employers to ensure monthly visual inspections and annual maintenance of portable extinguishers, while NFPA 10 describes inspection, maintenance, testing, and recordkeeping in more technical detail.
Monthly visual inspection is a quick in‑place look to confirm the extinguisher is present, accessible, and appears ready for use. Annual maintenance is a more thorough examination and service performed at least once a year by a trained person, and may trigger internal examinations or hydrostatic testing on longer intervals per NFPA 10.
OSHA Inspection Requirements (29 CFR 1910.157)
OSHA 29 CFR 1910.157(e)(2) requires that portable fire extinguishers be visually inspected at least once per month, and the employer is responsible for ensuring those inspections are completed. Under 1910.157(e)(3), OSHA also requires an annual maintenance check, and additional longer‑term service, such as six‑year internal examinations and 12‑year hydrostatic tests for certain extinguisher types, is referenced in 1910.157(e)(4).
OSHA’s focus is that extinguishers are in their designated locations, in operating condition, and ready for employee use, with records showing that monthly and annual requirements are being met. Employers may designate competent employees to conduct monthly visual checks, but are still accountable for compliance and for arranging qualified annual maintenance.
NFPA 10 Inspection, Testing, and Maintenance (ITM) Explained
NFPA 10, Standard for Portable Fire Extinguishers, organizes extinguisher care into inspection, maintenance, and testing (ITM). The standard requires visual inspections when extinguishers are first placed in service and then at least monthly, annual maintenance by a qualified person, and periodic hydrostatic testing based on extinguisher type and age.
In NFPA 10, inspection is the quick visual check to verify extinguishers are in place and appear operable, maintenance is a thorough examination and any necessary repair, and testing includes hydrostatic tests and other procedures to verify cylinder integrity. Authorities Having Jurisdiction (AHJs), such as the fire marshal, often adopt NFPA 10 by reference and will enforce these ITM requirements during fire code compliance inspections.
Monthly Visual Inspection Checklist (Portable Extinguishers)
Use this monthly portable extinguisher inspection checklist for basic code compliance. Each bullet should be verified and documented for every extinguisher.
- Verify the extinguisher is in its designated location.
- Confirm the extinguisher is easily visible and not obstructed by equipment, storage, or furniture.
- Check that the operating instructions on the label are facing outward and are legible.
- Inspect the cylinder, hose, and nozzle for obvious physical damage, corrosion, or leakage.
- Confirm the pressure gauge (if present) is in the operable/green range or that the weight is within acceptable limits for cartridge/CO₂ units.
- Verify the pull pin, tamper seal, and safety devices are intact and not missing or broken.
- Ensure the mounting bracket or cabinet is secure, and the extinguisher is properly hung.
- Check that required signage or identification labels are present and visible.
- Initial and date the inspection tag or log for that month, and note any deficiencies that require maintenance.
Annual Maintenance Checklist (by Trained Person)
Annual maintenance must be performed by a trained person or licensed extinguisher service company, following NFPA 10 procedures. This exam goes beyond visual checks and typically includes disassembly, internal inspection, and functional checks as required.
- Verify that all information on the extinguisher label, type, and size matches the hazard and location.
- Perform a detailed inspection of the cylinder, welds, valve, hose, and nozzle for damage, corrosion, or leakage.
- Check internal condition where required, including six‑year internal examinations on certain stored‑pressure dry chemical units.
- Verify pressure gauge accuracy or weight, and recharge or replace the extinguisher as required.
- Inspect and replace tamper seals, pull pins, o‑rings, and other critical components as needed.
- Confirm proper mounting height and location per code, including that the tops of most extinguishers are not more than about 5 feet above the floor.
- Conduct or schedule hydrostatic testing at intervals specified by NFPA 10 for the extinguisher type and date stamp.
- Affix a new annual maintenance tag or label with the date, company name, and technician identification, and update facility logs.
Documentation, Tags, and Logs
Code‑compliant extinguisher inspection programs rely on clear documentation that inspectors, fire marshals, and insurers can review. Each extinguisher should have an inspection tag or label showing at least the month and year of the last monthly check, the last annual maintenance, and the initials or ID of the person or company who performed the work.
Facilities should also maintain a central log or digital record listing extinguisher ID, location, type, monthly inspection dates, annual maintenance dates, and any deficiencies and corrective actions. Keeping these records on file helps demonstrate OSHA and NFPA 10 compliance during a fire code compliance inspection by the AHJ.
Common Fire Extinguisher Inspection Failures
Certain recurring issues show up frequently during extinguisher code compliance inspections. Addressing them proactively reduces citations and helps ensure extinguishers are usable in an emergency.
- Blocked or hard‑to‑reach extinguishers are behind storage, furniture, or equipment.
- Low or no pressure on the gauge, or extinguishers that feel unusually light for their size.
- Missing or broken pull pins, tamper seals, or damaged operating levers.
- Illegible labels or operating instructions, or extinguishers painted over.
- Rust, corrosion, dents, or leakage on the cylinder, hose, or nozzle.
- Expired or missing annual maintenance tags or hydrostatic test markings.
Who is Responsible for Extinguisher Inspections?
OSHA places responsibility for portable fire extinguisher inspection and maintenance on the employer, building owner, or other entity in control of the workplace. That responsible party may designate employees to perform monthly visual inspections and may contract with a licensed extinguisher service company for annual maintenance and testing.
Ultimately, the employer or property owner remains accountable to the Authority Having Jurisdiction and OSHA for ensuring that inspection frequencies are met, deficiencies are corrected, and documentation is maintained. Fire marshals or other AHJs verify compliance during fire code compliance inspections and can issue violations if the program is inadequate.
When a Fire Watch is Required During Impaired Fire Protection
If a building’s fire protection systems are impaired—for example, sprinklers or fire alarm systems are out of service—the AHJ or fire code may require a continuous fire watch until protection is restored. During a fire watch, trained personnel patrol affected areas, watch for hazards, and are prepared to initiate emergency procedures, functioning as a temporary safeguard when automatic systems or required extinguishers are not fully available.
This article should link to your more detailed fire watch guide using descriptive anchor text such as “fire watch during sprinkler or alarm impairment” so that both pages support each other in the broader compliance hub. Fire watch is a complement to, not a substitute for, a compliant fire extinguisher inspection, maintenance, and testing program.
Frequently Asked Questions
How often do fire extinguishers need to be inspected for OSHA compliance?
OSHA requires portable fire extinguishers to be visually inspected at least once per month and to receive an annual maintenance check by a trained person. Some extinguisher types also require six‑year internal examinations and 12‑year hydrostatic testing under OSHA and NFPA 10 guidance.
What is checked during a monthly visual fire extinguisher inspection?
During a monthly visual inspection, the inspector confirms each extinguisher is in its designated location, unobstructed, labeled, and appears undamaged and fully charged. The inspector also verifies that the pin and tamper seal are intact, the mounting is secure, the signage is visible, and the tag or log is updated with initials and date.
What’s the difference between inspection, maintenance, and testing?
Inspection is the quick visual check to verify placement, accessibility, and obvious readiness of the extinguisher. Maintenance is a thorough examination and repair performed at least annually by a qualified person, while testing refers to procedures such as hydrostatic tests that verify cylinder strength at longer intervals.
Who can perform monthly inspections vs. annual maintenance?
Monthly visual checks can be conducted by an employee, facility manager, or safety officer who knows what to look for and how to document findings. Annual maintenance and hydrostatic testing must be performed by a trained person or licensed extinguisher service company that follows NFPA 10 procedures and is acceptable to the AHJ.
What records are required for extinguisher inspections?
Each extinguisher should have an inspection tag or label showing the dates and initials for monthly inspections and the last annual maintenance. Facilities should also maintain central logs or digital records listing extinguisher locations, inspection dates, maintenance dates, and any deficiencies and corrective actions for review by OSHA and the fire marshal.
