NFPA 10 Compliance: Fire Extinguisher Inspection Requirements in Virginia, Maryland & DC

Fire extinguishers must be inspected annually by a certified technician per NFPA 10 (Standard for Portable Fire Extinguishers). In Virginia, Maryland, and Washington DC, local fire marshals require documented proof of these inspections during building compliance reviews. Failure to maintain current inspection records can result in fines, failed fire inspections, and potential liability exposure if a fire occurs.

Inspection Schedule Required by NFPA 10

Monthly visual checks verify that each extinguisher is in its designated location, the pressure gauge reads in the green zone, the safety pin and tamper seal are intact, and there is no visible damage or obstruction. Building owners or facility managers can perform these checks internally.

Annual professional inspections must be conducted by a certified fire protection technician. The technician examines the extinguisher’s mechanical components, verifies the agent charge weight, checks the hose and nozzle condition, and affixes a dated inspection tag. Homer Fire Protection’s NAFED-certified technicians perform these inspections across Northern Virginia, Maryland, and DC.

6-year maintenance requires a complete internal examination of stored-pressure extinguishers. The technician empties the extinguisher, inspects internal components for corrosion or damage, replaces any worn parts, recharges the unit, and applies a new 6-year maintenance label.

12-year hydrostatic testing subjects the extinguisher cylinder to a pressure test to verify structural integrity. Units that fail hydrostatic testing must be condemned and replaced. Certain extinguisher types, including CO2 units, follow a 5-year hydrostatic testing cycle instead.

Virginia, Maryland & DC Fire Code Requirements

Each jurisdiction in the DMV region enforces fire extinguisher requirements through its own fire prevention code, all of which reference NFPA 10 as the baseline standard:

Virginia follows the Virginia Statewide Fire Prevention Code (VSFPC), which adopts NFPA 10 and is enforced by local fire marshals. Commercial buildings must maintain fire extinguishers appropriate to the hazard classification of each area, and inspection records must be available for review during fire marshal visits.

Maryland enforces fire extinguisher requirements through COMAR 29.06 (Code of Maryland Regulations), which references NFPA 10. County-level fire marshals in Montgomery, Prince George’s, and other counties may impose additional requirements beyond the state baseline.

Washington, DC follows the DC Fire Prevention Code, which incorporates NFPA 10 requirements. The DC Fire and EMS Department conducts periodic inspections of commercial buildings to verify compliance with extinguisher placement, maintenance, and documentation requirements.

Penalties for Non-Compliance

Buildings found out of compliance during fire marshal inspections may face citation fines ranging from several hundred to several thousand dollars per violation, depending on the jurisdiction and severity. Repeated violations can result in occupancy restrictions or forced closure until deficiencies are corrected. Beyond regulatory penalties, buildings without properly maintained fire extinguishers face increased insurance premiums and significant liability exposure in the event of a fire-related injury or property damage claim.
