Industrial Fire Brigade: OSHA 1910.156 Requirements, Training Levels, and When One Is Required

Most facilities don’t need an industrial fire brigade. Your emergency action plan under 1910.38 can assign employees to use extinguishers on incipient fires and evacuate for anything larger. That’s a reasonable approach for most office buildings, light manufacturing, and warehouses with low fire load.

But some facilities genuinely can’t rely on that model. If your local fire department is 20 minutes out and you’re running a flammable liquid process, a chemical plant, or a facility with a high-ignition-risk environment, a 20-minute response time is the whole building. That’s the calculation that drives most brigade formation decisions.

OSHA 1910.156 doesn’t require you to form a fire brigade. What it says is: if you form one, here’s how it must operate.

When Facilities Decide to Form a Brigade

The trigger is usually one of four situations.

Remote location is the most common driver. If you’re more than 10 minutes from the nearest fire station with structural firefighting capability, a brigade gives you meaningful first-response time before the professionals arrive.

Hazardous materials processes push facilities toward brigades when the materials involved would be beyond normal fire department capability or would require specialized response. Chemical plants often form brigades because their fire scenarios involve specific chemicals their trained brigade members understand better than a general-service fire crew would on arrival.

Insurance requirements or permit conditions sometimes require a brigade. Some jurisdictions and some underwriters specify brigade requirements for facilities above certain sizes or hazard classifications.

Facility culture and corporate policy round out the list. Large industrial campuses often maintain brigades as part of a broader safety culture, even when the regulatory minimum wouldn’t require it.

The decision to form a brigade is a serious commitment. Once you have one, OSHA 1910.156 applies in full. You can’t form a brigade and then skip the PPE, training, or medical evaluation requirements. Some employers have dissolved brigades rather than meet the full requirements. That’s a legitimate choice, but it means your emergency action plan must address fire response some other way.

Brigade Organization: Incipient vs. Interior Structural vs. Combination

The three organizational levels defined in 1910.156 and NFPA 600 describe fundamentally different operations with very different resource requirements.

An incipient brigade handles fires in the beginning stage, before they’ve grown to involve structural materials or require entry into smoke-filled spaces. Incipient firefighting uses portable extinguishers or small hose lines. Members don’t wear structural firefighting gear. They wear their normal work PPE, which should already be appropriate for their work environment.

This is the right level for most industrial brigades. The mission is to knock down a small fire quickly and get everyone out before conditions deteriorate. Incipient brigade members aren’t meant to enter a burning structure or fight a fully involved fire. When a fire grows beyond incipient stage, the incipient brigade evacuates and waits for the fire department.

An interior structural brigade is a much bigger undertaking. These members enter burning structures, work in atmospheres that are immediately dangerous to life or health (IDLH), and fight fires that have progressed beyond incipient stage. They need the full package: structural firefighting gear, SCBA, PASS devices, and training that’s genuinely comparable to what municipal firefighters receive. Most industrial facilities don’t go this route because the cost, training burden, and liability are substantial.

A combination brigade does both. Some large industrial facilities, particularly petrochemical plants, oil refineries, and large paper mills, operate combination brigades with trained structural teams and a larger pool of incipient members. The structural team handles interior operations while incipient members support exterior operations and evacuation.

If you’re building a new program, start with incipient. That’s the most defensible choice for most facilities and the one OSHA’s requirements most clearly support.

OSHA 1910.156 Requirements

The standard has four main sections that matter operationally.

The organizational statement requirement at 1910.156(b) means you need a written document that establishes the brigade. It must describe the organizational structure, the expected number of members, the type of brigade (incipient, structural, or combination), and the duties the brigade will perform. This isn’t optional and it can’t be a handshake agreement.

Training and education requirements under 1910.156(c) set an annual minimum. Training must be appropriate to the duties assigned. If your brigade is incipient-only, their training needs to match that. But if you designate members as structural without giving them structural training and gear, you’ve created a scenario where undertrained workers might attempt interior attack because that’s what the job description says.

The physical capability requirements at 1910.156(e) apply to members who may be expected to use SCBA. Those members need a medical evaluation to confirm they’re physically capable of wearing SCBA during firefighting activities. This pulls in 1910.134, the respiratory protection standard, for the medical evaluation process.

PPE requirements at 1910.156(e) vary by brigade level, which is discussed in the next section.

PPE Requirements by Brigade Level

The gap between incipient and interior structural PPE is enormous. Getting this right matters because the wrong PPE in the wrong fire scenario is worse than no brigade at all.

Incipient brigade members don’t need specialized protective clothing beyond what their job requires. If they work in a chemical plant and already wear flame-resistant clothing as part of their daily PPE, that meets the incipient requirement. If they work in a standard manufacturing environment in regular work clothes, that may be sufficient for incipient firefighting where they’re not entering smoke or working around fully involved materials.

Interior structural brigade members need the complete set:

• Protective coat and trousers meeting NFPA 1971 standards
• Structural firefighting helmet
• Structural firefighting boots
• Structural firefighting gloves
• NIOSH-approved SCBA with a minimum 30-minute rated capacity
• Personal alert safety system (PASS device) integrated with or attached to the SCBA
• Hood or other appropriate head protection

The employer provides all of this at no cost to brigade members. That requirement is non-negotiable under 1910.132 and 1910.156. Members can’t be asked to supply their own structural firefighting gear.

Protective clothing must be inspected regularly and maintained per manufacturer specifications. Gear that’s been exposed to fire, chemical contamination, or excessive wear has to be evaluated before the next use. There’s no general inspection interval defined by OSHA for structural gear. NFPA 1851, the standard on selection, care, and maintenance of structural firefighting protective ensembles, provides the framework most programs use.

Medical Evaluations for SCBA Users

Anyone expected to use SCBA during firefighting operations needs a medical evaluation before they’re assigned to that duty. This requirement comes from 1910.134(e), the respiratory protection standard.

The evaluation must be conducted by a physician or other licensed health care professional (PLHCP). The evaluation uses a medical questionnaire, and the PLHCP may require a follow-up exam based on responses. The minimum information a PLHCP needs includes the type of SCBA, the conditions of use (firefighting is specifically more demanding than industrial respirator use), and the specific physical demands the member will face.

SCBA for firefighting is categorized separately from industrial SCBA use in most medical evaluation protocols. The physical demand of wearing a 25-30 pound SCBA while performing firefighting tasks under high heat and stress is genuinely strenuous. Members with cardiovascular disease, severe respiratory conditions, or other conditions that limit physical exertion may not be medically cleared.

Medical evaluations must be repeated whenever there’s a change in conditions that could affect physical ability, when a member requests a re-evaluation, or when the PLHCP determines a follow-up is needed. Annual re-evaluation is a common industry practice even when OSHA doesn’t specify an interval.

The medical evaluation records are confidential. The employer gets only a written opinion from the PLHCP that states whether the member is medically able to use the respirator, any limitations, and whether additional evaluation is needed. The PLHCP doesn’t share medical details with the employer.

Training Documentation Requirements

OSHA 1910.156(c) requires training but doesn’t specify a recordkeeping format. That leaves the documentation method up to you, which means you need to build a system that demonstrates compliance if OSHA shows up.

At minimum, your training records should capture:

• Date of training
• Topic or curriculum covered
• Instructor name and qualifications
• Names of all members who attended
• Duration of the training

For interior structural brigade members, document SCBA use training separately and track fit testing records under 1910.134’s fit test documentation requirements. If a member’s SCBA fit test is overdue, they can’t use SCBA in an emergency.

NFPA 600 recommends training frequency beyond OSHA’s annual minimum. Monthly drills are common on industrial sites with active brigades. The argument for more frequent training is straightforward: fire response is a perishable skill. An annual classroom session doesn’t replicate the stress, communication demands, and physical exertion of an actual fire response.

Building the Program: Policy, Selection, Training Schedule

A functional fire brigade program has four components that have to work together.

The written policy establishes the brigade’s existence, its organizational level, its chain of command, and its authority. It should name the position (not person) who leads the brigade, define how the brigade activates during an emergency, and describe how it coordinates with local fire department response. Update it whenever the organizational structure or facility conditions change.

Member selection criteria should match the physical and skill demands of the brigade level. For incipient brigades, the main qualification is availability, basic training completion, and willingness. For structural brigades, physical fitness and medical clearance become screening requirements. Don’t allow members on the structural roster who haven’t completed medical evaluation and SCBA fit testing.

The training schedule needs to cover initial qualification training for new members and ongoing training for all members. New incipient members need fire behavior fundamentals, extinguisher selection and use, and how to recognize when a fire is beyond incipient stage. New structural members need all of that plus hands-on SCBA training, structural firefighting techniques, and simulated operations.

Coordination with your local fire department is worth more than most programs give it credit for. Invite the local fire department for a pre-incident planning walkthrough. Share your facility layout, hazardous materials inventory, utility shutoffs, and process hazards. When they respond to your facility in a real incident, that relationship and that pre-incident knowledge directly affects outcomes.

Review the entire program annually. Check whether your brigade size still matches your facility population and fire risk. Confirm that all members are current on training and medical evaluations. Verify that PPE is in serviceable condition. And make sure your emergency action plan reflects how the brigade actually operates today, not how it was designed three years ago.
