Top 10 NFPA 10 Violations We See on Northern Alberta Sites

NFPA 10 — the Standard for Portable Fire Extinguishers — is the compliance framework that governs fire extinguisher placement, maintenance, and documentation across Alberta industrial and commercial operations. The Alberta Fire Code adopts NFPA 10, making these requirements enforceable under provincial law.

After years of servicing extinguishers across oilfield sites, industrial facilities, and contractor fleets in Northern Alberta, these are the violations that appear most often — and the ones that generate the most findings during HSE audits and AHJ inspections.

The most common finding by a wide margin. Every extinguisher must receive a certified annual inspection — and the inspection tag must show a current date. Units that have been in service for 13 or 14 months without a current tag are non-compliant, regardless of their mechanical condition.

NFPA 10 requires documented monthly visual inspections. Many sites perform the walk-around but don't record it. No documentation means no compliance — an inspector cannot take your word for it.

Extinguishers must be mounted in accessible, visible locations. Units blocked by stored materials, parked equipment, or enclosed in unlocked but unmarked cabinets without signage are a violation. On industrial sites with changing yard layouts, obstruction issues are especially common.

NFPA 10 sets maximum mounting heights based on the weight of the extinguisher. Units weighing 40 lbs or less must have the handle no higher than 5 feet from the floor. Heavier units must be mounted lower. Extinguishers zip-tied to fencing or mounted on improvised brackets at non-compliant heights are a recurring finding.

The pull pin must be secured with a tamper-evident seal. A broken, missing, or makeshift seal (electrical tape does not count) is a violation. On heavy equipment, vibration alone can break seals between inspections.

Stored pressure dry chemical extinguishers require hydrostatic testing every 12 years. CO2 and wet chemical units require it every 5 years. Many operators are unaware of this interval — especially for extinguishers that have been in service since a facility was built. A unit that has never been hydro-tested and is more than 12 years old is non-compliant and must be tested or removed from service.

Placement must match the hazard class. A dry chemical ABC extinguisher near a deep fryer should be a Class K wet chemical unit. A water-based unit near electrical equipment is a hazard in itself. As operations evolve, the extinguisher inventory often does not keep pace.

NFPA 10 specifies maximum travel distances to an extinguisher based on hazard class. For ordinary hazards, no point in a building should be more than 75 feet from an extinguisher. For high-hazard areas, that drops to 50 feet. Facilities that have expanded without adding extinguisher coverage are routinely out of compliance on this point.

Every six years, stored pressure dry chemical extinguishers must undergo an internal examination — not just an external inspection. The internal components must be checked, the agent condition assessed, and the service documented with a 6-year maintenance label on the cylinder. Many extinguishers in the field have annual inspection tags but no 6-year label — meaning the internal maintenance has either not been done or was not documented.

The inspection tag must be legible, attached, and include the technician's name, certification number, and the date of service. Sun-faded, water-damaged, or partially missing tags are a violation — even if the underlying inspection was performed correctly. On outdoor industrial sites, tag durability is a real issue.
