TL;DR
OSHA's 29 CFR 1910.157(g) requires employers to train employees on fire extinguisher use at least once a year. If your policy is to evacuate instead of fight fires, you must still tell employees that annually. Hands-on training is required for anyone expected to grab an extinguisher. There's no minimum hour count, but you have to document it.
What does OSHA actually require for annual fire extinguisher training?
The rule is 29 CFR 1910.157(g). Employers must train designated fire fighters on the equipment "upon initial assignment to the designated group and at least annually thereafter," and the standard says the employer "shall provide employees who have been designated to use fire fighting equipment as part of an emergency action plan with training in the use of the appropriate equipment." [1]
That covers employees who are expected to use an extinguisher. There's a second group too: employees whose job under the emergency action plan is to evacuate and leave the fire to the fire department. For them, 29 CFR 1910.157(g)(1) still requires the employer to "apprise" them of the hazards and the employer's policy at initial employment and annually after that. [1] So no matter your policy, some form of annual communication is required for every employee on the payroll.
The practical difference is big. Tell workers to grab an extinguisher and knock down a small fire before leaving, and they need real hands-on training. Tell them "pull the alarm and get out," and a short annual briefing on why you have that policy satisfies the standard.
OSHA sets no minimum number of training hours. Its letters of interpretation say the training has to be "adequate" for the hazard, which is deliberately vague and gives you room to work. In practice that means one PowerPoint slide shown once a year probably won't survive a citation. A 30-minute session with an extinguisher in hand usually will.
Who exactly has to get trained, and how often?
Every employee, every year, at some level. That's the short answer.
The longer answer depends on your emergency action plan (EAP). Under 29 CFR 1910.38, most employers with more than 10 employees need a written EAP. [2] That plan names who's expected to use fire extinguishers if a fire starts. Those designated employees get the full treatment: how to size up a fire, how to run a specific extinguisher type, when to stop fighting and get out.
Employees who aren't designated as fire fighters under the EAP still get annual awareness-level communication. A quick team meeting, a toolbox talk, or a written notice all work, as long as you can prove it happened.
New hires need training before they start working in the area, not at the next scheduled annual session. OSHA is explicit that initial training happens "upon initial assignment." [1] If someone switches departments and the move changes their fire-fighting designation, retrain them before that move is complete.
Contractors are a gray area. If they work in your facility, your general duty to keep a safe workplace under Section 5(a)(1) of the OSH Act says you should at least walk them through your evacuation plan and confirm they've had their own extinguisher training. Compliance officers often ask whether you communicated your EAP to contractors during an inspection.
What does OSHA-compliant fire extinguisher training actually look like?
There's no federally mandated curriculum. But OSHA's compliance guidance and the National Fire Protection Association's NFPA 10 standard (the inspection and maintenance standard most states reference) point at the same core content. [3]
For designated fire fighters, training should cover:
- The classes of fire: A (ordinary combustibles), B (flammable liquids), C (energized electrical), D (combustible metals), K (cooking oils). The wrong extinguisher on the wrong fire can make things much worse.
- The PASS technique: Pull the pin, Aim at the base of the fire, Squeeze the handle, Sweep side to side. It's more than a mnemonic. Employees who've never practiced under even mild stress tend to aim at the flames instead of the base.
- How to read the gauge and spot an extinguisher that's out of service.
- When to stop. If the fire is bigger than a wastebasket, the room is filling with smoke, there's no clear exit behind you, or the extinguisher doesn't knock it back in the first 15 to 20 seconds, evacuate.
- The specific extinguisher types in your building. A restaurant with a K-class unit under the hood trains differently than a warehouse running dry chemical ABC units.
Hands-on practice is what separates training that holds up on inspection from training that doesn't. Live-fire practice (using a propane-based training fire) is ideal. Extinguisher trainers that use laser or water-based simulation are a fair substitute when live fire isn't practical. Simulation-only isn't prohibited, but it's harder to defend if OSHA asks whether the training matched the actual hazard.
For employees under an evacuate-only policy, the annual communication needs to cover the employer's policy, the location of exits and assembly points, who to notify, and why the policy exists. That last piece matters. Employees who understand that an uncontrolled fire can double in size in a minute are more likely to follow an evacuate-first policy without second-guessing it.
Does fire extinguisher training need to be documented?
OSHA's 29 CFR 1910.157 has no explicit documentation requirement, unlike hazard communication or lockout tagout. That does not make records optional.
Here's why you keep them anyway. When OSHA investigates after a fire, or a compliance officer runs a programmed inspection, the question "did you train your employees this year" has exactly one good answer: a sign-in sheet with dates, names, and topics covered. "We do it verbally every year" is the answer that gets you cited.
State plan states sometimes add their own documentation rules. California's Cal/OSHA requires employers to keep training records as part of the Injury and Illness Prevention Program. [4] Check your state.
A practical minimum for any employer: a sign-in sheet or attendance record showing date, employee names, trainer name, and topics covered. Keep those records at least three years, which is the standard retention window for most safety records even when it isn't spelled out. If you use an online platform, export and save the completion certificates.
SafetyFolio's safety program generator produces a training log template in the format compliance officers expect, as part of a full written program in about 15 minutes. Use that or build your own. The template matters less than actually filling it out every single year.
What are the OSHA penalties if you skip fire extinguisher training?
A violation of 29 CFR 1910.157(g) is usually cited as a serious violation, which as of 2024 carries a maximum penalty of $16,131 per violation. [5] Willful or repeat violations can hit $161,323 per instance. [5]
OSHA adjusts penalties on gravity (how likely and how severe the harm), employer size, good faith, and history. A small employer with no prior citations and a real attempt at compliance can see the penalty cut sharply. A large employer with a history of fire safety violations, or one where the inspector finds employees who plainly can't use the extinguishers on the wall, lands at the high end.
The real cost usually isn't the OSHA fine. It's the workers' compensation claim, the property damage, and the liability that follow an actual fire. The Bureau of Labor Statistics doesn't publish a standalone "fire injuries from lack of training" figure, but fires and explosions accounted for 52 fatal work injuries in 2022. [6] Non-fatal fire and burn injuries at work ran into the thousands that year.
Skipping training is false economy, plain and simple.
How is portable fire extinguisher training different from fire brigade training?
These are two separate OSHA standards, and people confuse them constantly.
29 CFR 1910.157 covers portable fire extinguishers: the wall-mounted units every office, shop, and warehouse has. This is the rule most small businesses need to worry about.
29 CFR 1910.156 covers fire brigades: organized teams of employees who perform interior structural firefighting as part of their job. [7] That standard is much heavier. It requires medical evaluations, protective clothing, quarterly practice sessions, and annual training on the specific hazards in your facility. Very few small businesses have a fire brigade in the OSHA sense.
If your "fire team" is a couple of employees who agreed to knock down a small fire with an extinguisher before evacuating, you're under 1910.157, not 1910.156. That's almost certainly where you belong. The distinction has teeth: trying to comply with 1910.156 when you don't need to burns time and money, and mistaking 1910.157 as adequate when you actually run interior fire attacks creates real legal exposure.
For general osha training on how these standards fit into a broader safety program, see our overview of how OSHA organizes its training requirements.
Can fire extinguisher training be done online?
Partly. The awareness-level training for evacuate-only employees can reasonably be done online or with a short video. OSHA's interpretation letters have generally supported computer-based training where the material doesn't require hands-on demonstration of a skill. [8]
For employees expected to actually use an extinguisher, online-only training is legally defensible but weak in practice. If an employee watches a video and then can't operate a pull-pin extinguisher, your training was inadequate no matter what certificate it spit out. The standard requires that the training make the employee capable of using the equipment safely, not merely exposed to information about it.
The best approach for most small businesses is a short online or video component covering the theory (fire classes, PASS technique, when to stop fighting), then a 15 to 20 minute hands-on session where each employee physically works a training extinguisher. That combination is both cheap and defensible.
Training extinguishers that use water or dry nitrogen (no mess, reusable) cost roughly $150 to $300 each and pay for themselves after one training cycle versus replacing discharged ABC units. Some fire equipment vendors loan or rent them. Local fire departments sometimes run free or low-cost sessions for small businesses, which is worth a phone call before you spend a dime.
What's the difference between fire extinguisher training and the annual inspection requirement?
Two different obligations, both annual, both under 1910.157, and they get mixed up constantly.
Training is what employees need to know and be able to do. Inspection is the physical check of the extinguisher units themselves.
29 CFR 1910.157(e) requires that extinguishers be visually inspected monthly and submitted for annual maintenance by a qualified person. [1] The annual maintenance (don't confuse it with the monthly visual check) must be documented on a tag attached to the extinguisher or in a separate record. This is the service your fire equipment vendor runs once a year.
The monthly visual check is usually done by someone internal. You're confirming the extinguisher is in its spot, the gauge reads in the green, the pull pin is intact and the tamper seal is unbroken, and there's no obvious damage. That check takes about 30 seconds per unit and should be logged.
Some employers schedule their annual employee training to land on the same day as the vendor's annual maintenance visit. That's a clean move. The vendor services the units while you do the training, and you can point to both sets of records on one date.
Do state plan states have stricter fire extinguisher training rules?
Yes, some do. Twenty-nine states and territories operate their own OSHA-approved state plans, and those plans have to be at least as effective as federal OSHA but can go further. [9]
California (Cal/OSHA) has extra requirements tied to its Injury and Illness Prevention Program that effectively require documented training programs for fire extinguisher use. Washington State (L&I) and Michigan (MIOSHA) have similarly detailed guidance. Oregon OSHA has published specific guidance on extinguisher training documentation.
In a state plan state, you cannot lean on the federal 1910.157 text alone. Look up your state's equivalent standard. The OSHA website keeps a map and contact list for every state plan program. [9]
For the 21 states under federal OSHA jurisdiction, 1910.157 is your primary standard, though some local fire codes (enforced by the local fire marshal, not OSHA) can add requirements. Those are usually about extinguisher placement and servicing rather than training, but it varies by jurisdiction.
How do you build a fire extinguisher training program from scratch?
Start with your emergency action plan. If you have one, pull it out and find which employees are designated to use extinguishers. If you don't have one and you employ more than 10 people, that's the first gap to close. [2]
Then work through these steps:
1. Inventory your extinguishers. Know the type (ABC dry chemical, CO2, K-class, and so on), location, and service date of every unit. You can't train employees on equipment they've never seen.
2. Decide your policy. Fight small fires or always evacuate? Document that choice in your EAP. Neither answer is wrong. OSHA accepts both. But you have to pick one and train to it.
3. Build or buy your training content. The OSHA website has free training materials. NFPA also publishes guidance. [3] For a ready-made written program covering both the training element and the broader fire safety requirements, the SafetyFolio program generator builds a compliant written program with training documentation templates in one session.
4. Deliver the training. For designated fire fighters, that means a hands-on component. Schedule it before your annual extinguisher maintenance visit so you can tie both records together.
5. Document everything. Name, date, trainer, topics, and whether hands-on practice was included.
6. Set a calendar reminder. Annual means within 12 months of the last session, not "sometime around when we did it last year." Training that slips to 14 months is out of compliance.
Repeat. That's the whole program.
What questions do OSHA inspectors actually ask about fire extinguisher training?
Based on OSHA's inspection procedures and letters of interpretation, here's what a compliance officer is likely to ask when they walk your facility: [8]
- Can you show me your emergency action plan and who's designated to use fire extinguishers?
- When did you last conduct fire extinguisher training, and can I see the records?
- If I pull an employee aside and ask them to walk me through using one of these extinguishers, will they be able to do it?
That third question is the one that trips employers up. A sign-in sheet proves someone sat in a room. It doesn't prove they learned anything. Inspectors do sometimes ask employees directly, especially after an incident prompted the inspection.
The practical defense: run training where employees physically handle the equipment, keep sign-in sheets, and do a quick verbal check at the end ("show me where you'd aim this") so you can honestly document that competence was confirmed. That's not a legal requirement. It's the kind of documentation that makes a compliance officer nod and move on.

Frequently asked questions
Is fire extinguisher training required by OSHA every year?
Yes. 29 CFR 1910.157(g) requires training for designated fire fighters upon initial assignment and at least annually after that. Employees under an evacuate-only policy must be informed of that policy and the hazards at least annually. There's no exemption for small businesses, though the depth of training scales with your policy.
What happens if I don't train my employees on fire extinguishers?
OSHA can cite you under 29 CFR 1910.157(g) as a serious violation, with penalties up to $16,131 per violation as of 2024. More practically, an untrained employee using the wrong extinguisher on the wrong class of fire can make a fire worse. Workers' compensation and liability costs from a workplace fire typically dwarf any OSHA fine.
How long does fire extinguisher training need to be?
OSHA sets no minimum duration. The standard requires training that makes employees capable of safely using the equipment. In practice, a 20 to 30 minute session covering fire classes, the PASS technique, and hands-on practice with a training extinguisher satisfies the requirement for most workplaces. Awareness-level training for evacuate-only employees can be shorter.
Can I train employees on fire extinguishers myself, or do I need a certified trainer?
OSHA does not require a certified or licensed trainer for 1910.157 fire extinguisher training. You can run it yourself if you understand the equipment and the standard. Many employers use their fire equipment vendor or the local fire department for the hands-on part, which is practical and adds credibility to your records.
Do part-time or temporary employees need fire extinguisher training?
Yes, if they work in the area and might meet a fire. OSHA's training requirements apply based on job duties and location, not employment classification. A temp in a warehouse under an evacuate-only policy still needs the annual awareness briefing. If a temp is designated to fight fires under the EAP, they need the full hands-on training before starting work.
Does my company need fire extinguishers at all, or can we just rely on sprinklers?
If your employees won't be expected to use portable extinguishers and you have a sprinkler system plus an evacuate-only EAP, 29 CFR 1910.157(b)(1) lets you forego portable extinguishers. But you must document that decision and still train employees on your evacuation policy. Most small businesses keep extinguishers because the cost of removal and the policy formality aren't worth it.
What's the PASS technique and does OSHA require employees to know it?
PASS stands for Pull the pin, Aim at the base of the fire, Squeeze the handle, Sweep side to side. OSHA doesn't mandate this specific acronym by name, but proper operation of the extinguisher is required content. PASS is the industry-standard way to teach that operation, and nearly all training programs use it.
How do fire extinguisher training requirements differ from fire brigade requirements?
Fire brigade requirements under 29 CFR 1910.156 apply to organized employee teams who perform interior structural firefighting as part of their jobs. Those have much heavier requirements including medical evaluations, quarterly drills, and full protective equipment. Most small businesses fall under 1910.157 for portable extinguisher use only. Confusing the two standards leads to over-compliance costs or legal exposure.
Do I need to document fire extinguisher training if OSHA doesn't explicitly require it?
OSHA 1910.157 has no explicit documentation requirement, but keeping records is effectively mandatory in practice. Without a sign-in sheet or attendance log, you have no way to demonstrate compliance during an inspection or after an incident. Keep training records at least three years. State plan states like California may have explicit documentation requirements tied to their IIPP rules.
Can fire extinguisher training be done online?
Online training can satisfy the awareness component for evacuate-only employees. For employees expected to use an extinguisher, online training alone is hard to defend if they can't actually operate the equipment. The best approach is a short online or video module covering theory, then a brief hands-on session with a training extinguisher. That combination is cost-effective and defensible under 1910.157(g).
How often do fire extinguishers themselves need to be inspected, separate from training?
29 CFR 1910.157(e) requires monthly visual inspections by an employee and annual maintenance by a qualified service person. The monthly check confirms the unit is accessible, the gauge reads in the green, and the tamper seal is intact. Annual maintenance, done by your fire equipment vendor, requires a tag or written record. These are equipment requirements, separate from the annual employee training obligation.
Are there special training requirements for Class K fire extinguishers in restaurants?
OSHA's standard doesn't carve out special training rules by extinguisher class, but training must cover the specific equipment in your workplace. Employees in a commercial kitchen should be trained on Class K extinguishers specifically, including the fact that a Class K unit on a cooking oil fire produces a fine mist that creates a vapor barrier rather than a suppression agent. Using an ABC dry chemical unit on a grease fire can cause violent splatter.
What if I have fewer than 10 employees? Do fire extinguisher training requirements still apply?
Yes. 29 CFR 1910.157(g) applies regardless of company size. The 10-employee threshold only affects whether you need a written emergency action plan under 1910.38. A company with nine employees can communicate the EAP orally, but still must conduct annual fire extinguisher training for designated employees and annual hazard awareness for everyone else.
