Guides for the trade

The cadence questions, answered plainly — how the annual, 6-year, 12-year, and semi-annual dates are set — and the business of running a route. Free to read, nothing to sign up for.

Inspection cadence

How often do fire extinguishers need inspection?

The short answer has four parts under NFPA 10: the owner visual check, the annual maintenance, the 6-year internal exam, and the 5- or 12-year hydrostatic test.

The NFPA 10 inspection checklist for portable extinguishers

The itemized annual maintenance walk for portable fire extinguishers under NFPA 10 — what a technician checks, records, and tags on each unit, one by one.

Fire extinguisher 6-year maintenance requirements

What the 6-year internal examination covers for stored-pressure dry-chemical extinguishers under NFPA 10, and which agents run on a different clock.

Fire extinguisher hydrostatic testing: the 5- and 12-year cycles

How hydrostatic testing works for portable fire extinguishers, and why the interval is 5 years for some agents and 12 years for others under NFPA 10.

Kitchen hood suppression inspection frequency

How often pre-engineered kitchen hood fire suppression systems must be serviced under NFPA 96 and UL-300 — the semi-annual rule, explained plainly.

Exit and emergency light testing requirements

The testing schedule for emergency and exit lighting under NFPA 101 — the annual 90-minute test and the monthly function test, and who owns each.

Fire extinguisher service tags, explained

A fire extinguisher service tag is the dated, per-serial record of the last service. Here is what it records, and why a fire marshal reads it first.

What a fire marshal checks on an inspection

A plain walkthrough of what a fire marshal actually checks on inspection day, from extinguisher tags to exit lighting, so you can read the room too.

Fire extinguisher types and agents, explained

A field guide to portable extinguisher agents — ABC, BC, Purple-K, CO2, water, wet chemical, clean agent, foam, and halon — and why the agent sets the schedule.
