Fire Extinguisher Inspections 101: Staying Code-Compliant Year-Round

Of everything we inspect, fire extinguishers are the most overlooked — probably because they're small, they're cheap, and they sit quietly on a wall doing nothing 99.9% of the time. But when a local fire marshal walks your building, that little tag is often the first thing they check. And when a small kitchen fire or an electrical spark turns into a real problem, it's often the first thing an employee reaches for.

Monthly vs. annual: what's actually required

There are two different clocks running on every extinguisher in your building, and mixing them up is the most common compliance mistake we see.

• Monthly visual checks — a quick look to confirm it's in place, the pressure gauge is in the green, the pin and seal are intact, and nothing is blocking access. This can be done by staff and just needs to be logged on the tag.
• Annual professional inspection — a licensed technician checks the extinguisher inside and out, weighs it, tests the hose and nozzle, and tags it with the date and their certification number.

Some extinguisher types also need hydrostatic testing every 5–12 years depending on the model, which is a deeper check on the tank itself. Most restaurant and office buildings won't hit that milestone often, but it's worth knowing it exists so a technician's recommendation doesn't catch you off guard.

The right extinguisher in the right spot

Not every extinguisher is built for every fire. A restaurant kitchen needs a Class K near the cook line for oil and grease fires, in addition to general-purpose ABC extinguishers elsewhere in the building. Server rooms and areas with sensitive electronics often call for clean-agent extinguishers that won't ruin equipment. Placement matters too — code generally requires an extinguisher within 75 feet of any point in the space, and they need to be visible and unobstructed, not tucked behind a shelf of dry goods.

The best extinguisher in the world doesn't help anyone if nobody can find it, or if it hasn't been checked since last spring.

A simple system that actually gets followed

The businesses that stay compliant year-round aren't doing anything complicated — they've just made it someone's job. A manager does the monthly walk-through on the same day each month, initials the tag, and knows who to call for the annual service. That's it. It's the businesses without an owner is the one who checks that tend to fall behind.

1. Assign the monthly check to a specific role, not "whoever remembers."
2. Keep your annual inspection on a recurring calendar reminder, not a sticky note.
3. Know your extinguisher count and types before an inspector asks — walk your own space once a year like you're the one grading it.

If it's been a while since anyone's looked closely at your extinguishers — or you're not sure you have the right types in the right places — that's an easy fix, and usually a fast one.
