FDNY requires three levels of fire extinguisher inspections under NFPA 10: monthly visual inspections, annual maintenance, and 6- or 12-year testing, depending on the extinguisher type. Missing any of these inspections can result in FDNY violations, corrective action orders, and potential fines. This checklist walks you through the key requirements to help keep your extinguishers compliant, functional, and ready for use during an emergency.

Monthly Visual Inspection Checklist
NFPA 10 requires monthly inspections to verify that extinguishers remain ready for use. Any trained staff member can perform these checks. A Certificate of Fitness is not required for visual inspections.
Checklist Part 1: Location and Accessibility
- Check the mounting position. The extinguisher must be mounted at least four inches above the floor, and the top of the unit cannot exceed five feet from the floor. Wall brackets should hold the extinguisher securely without wobbling.
- Verify clear access. No boxes, equipment, furniture, or other obstructions should block access to the extinguisher. FDNY may treat blocked extinguishers the same as missing extinguishers when issuing violations.
- Confirm visibility. Operating instructions should face outward and remain easy to read. Location signage can help occupants quickly identify extinguishers during emergencies or low-visibility conditions.
Checklist Part 2: Physical Condition Check
- Examine for damage. Look for dents, corrosion, rust, leaking agent around the valve assembly, or other signs of physical damage. Inspect the hose for cracks, brittleness, or wear. Damaged extinguishers should be removed from service and professionally evaluated immediately.
- Inspect the safety seal. The tamper seal must remain intact and unbroken. A broken seal may indicate the extinguisher has been used or tampered with. Even a partial discharge typically requires professional recharging and inspection.
- Verify the pressure gauge reading. The gauge needle should remain within the green operating range. Readings in the red zone indicate the extinguisher may not discharge properly during an emergency and should be serviced or replaced immediately.
Checklist Part 3: Documentation Requirements
- Date and initial the inspection tag. FDNY requires monthly inspection documentation for each fire extinguisher. Inspection tags should clearly show the month of inspection and the inspector’s initials. Missing, incomplete, or outdated tags can result in VC51 violations during FDNY inspections.
- Record problems immediately. Document any deficiencies, corrective actions, or service needs identified during the inspection. If an extinguisher is removed from service, record the reason and the date it was taken out of service to maintain accurate compliance records.
Annual Maintenance Requirements
NFPA 10 mandates annual maintenance by certified technicians. New York City requires all service companies to hold current FDNY approval. Check the FDNY website for approved portable fire extinguisher companies before scheduling service.
What Annual Service Includes
During annual maintenance, a certified technician conducts a detailed inspection to ensure the extinguisher remains operational and FDNY-compliant.
Key tasks include:
- Testing the discharge valve, safety pin, and handle for proper operation
- Inspecting hoses and connections for damage, blockages, or corrosion
- Checking moving parts for wear and deterioration
- Verifying charge levels in stored-pressure extinguishers
- Weighing cartridge-operated units to confirm the correct agent quantity
After the inspection:
- A new FDNY-compliant service tag is applied
- The tag includes the maintenance date, technician information, and company details
- Required security features, such as QR codes and holograms, verify compliance and authenticity
Testing Schedule by Extinguisher Type
Different extinguisher types follow specific testing intervals under NFPA 10. Know your equipment to track correct service schedules.
Stored-pressure fire extinguishers require internal examination to inspect cylinder walls for corrosion and scaling. Technicians remove all agents during this process. The six-year requirement applies to ABC dry chemical extinguishers commonly found in commercial buildings.
Hydrostatic tests verify cylinder integrity by pressurizing the shell with water to a pressure exceeding the normal operating pressure. Only certified facilities with proper equipment can perform these tests. Extinguishers failing hydrostatic tests must be condemned and replaced.
Preparing for FDNY Inspections
FDNY conducts annual inspections of commercial buildings. Buildings with three or more residential units receive annual inspections. High-rise structures over 75 feet tall get semi-annual inspections.
Before the Inspector Arrives
- Complete your own walkthrough. Check every extinguisher location against your floor plan, verify that all units have current inspection tags, and confirm clear access and proper mounting heights throughout the building.
- Organize documentation. Gather annual service records from your FDNY-approved contractor and maintain copies of purchase receipts for any replacement extinguishers.
- Correct obvious problems. Replace missing or damaged extinguishers and remove any obstructions that could block access during an inspection.
Special Considerations for NYC Buildings
New York City fire code includes specific requirements beyond the base NFPA 10 standards. FDNY mandates particular tag formats with security features. Only approved companies can sell or service commercial fire extinguishers in the five boroughs.
- Commercial Kitchen Requirements
Kitchens with cooking equipment need Class K extinguishers within 30 feet of all appliances. These wet chemical units handle grease fires that ABC extinguishers cannot control effectively. NFPA 96 and FDNY Section 609 require semi-annual inspections of commercial kitchen fire suppression systems. - High-Rise Building Protocols
Buildings exceeding 75 feet in height face additional inspection frequencies and documentation requirements. Emergency action plans should include extinguisher locations and proper use procedures. Standby fire extinguishers during hot work operations require documented permits.
