Fire needs fuel, heat and oxygen. You prevent workplace fire hazards by keeping fuel and ignition sources apart, and by making sure that if a fire starts anyway, people can detect it, control it if they are trained to, and get out. The seven practices below cover both sides, and for most U.S. general industry employers several of them are OSHA requirements, not suggestions.
Consider a common sequence. A maintenance tech cuts a bracket off a mezzanine rail late in the shift, packs up and leaves. A spark that dropped into a cardboard bale below smolders unnoticed. Every control in this article exists to break a chain like that one: the hazard inventory that flags the bale, the hot work authorization that moves it, the fire watch that stays after the cut, the extinguisher that is charged and in reach, and the evacuation plan everyone has practiced.

Which OSHA Standards Apply?
This article covers general industry (29 CFR 1910). Construction work falls under 29 CFR 1926, which has its own fire protection and hot work provisions. States that run OSHA-approved State Plans can adopt requirements that differ from or go beyond the federal rules, so check your State Plan if you operate in one. |
You cannot control a hazard you have not named. OSHA's fire prevention plan standard, 29 CFR 1910.39, gives you a ready-made structure for the inventory. The standard applies when another OSHA standard requires a fire prevention plan (FPP), such as the extinguisher exemptions covered in section 6. Even where it is not required, its elements make a sound template. An FPP must include:
The plan must be in writing, kept in the workplace and available for employees to review, unless you have 10 or fewer employees, in which case you may communicate it orally. You must also tell each employee, upon initial assignment to a job, about the fire hazards they are exposed to, and review with each employee the parts of the plan they need for self-protection.
Walk the site with the five elements in hand. Look at storage areas with combustible packaging, flammable liquid dispensing and storage, heat-producing equipment such as ovens, dryers, furnaces and space heaters, electrical rooms and panels, processes that generate combustible dust, and areas where hot work happens. The third element is easy to underwrite: a dryer's high-limit control or an oven's residue cleaning schedule is a safeguard on heat-producing equipment, and it needs a maintenance procedure and a named owner, not just a mention.
Where EHS Insight fits: The Hazard Identification and Risk Assessment (HIRA) module is designed to identify organizational hazards and assess and manage their risks over time, including the controls you put in place, so your fire hazard list stays current instead of living in a binder. See all EHS Insight modules.
Fire safety advice often frames this risk as household versus commercial appliances. The OSHA rule is more precise. Under 29 CFR 1910.303, electrical equipment is acceptable only if it is approved, as defined in 1910.399, and listed or labeled equipment must be installed and used in accordance with any instructions included in the listing or labeling. Equipment must also carry the manufacturer's name and its voltage, current, wattage or other ratings, and under 1910.305 every electric appliance needs a nameplate giving its rating in volts and amperes or volts and watts.
So the question to ask is not where a heater or coffee maker was sold. It is whether you are using it the way its listing and instructions allow. A unit run continuously, on a circuit it was not rated for, or through an extension cord its instructions prohibit is outside those limits. Many space heater manufacturers, for example, instruct users to plug directly into a wall receptacle.
Under 1910.303, electric equipment must be free from recognized hazards likely to cause death or serious physical harm, and completed wiring installations must be free from short circuits and from grounds other than those the standard requires or permits. Overcurrent protection, meaning breakers and fuses, belongs in the fixed installation and is selected and coordinated for the circuit. It is a design job for a qualified electrician, not something you add appliance by appliance.
Flexible cords deserve the closest look on any walkdown. Unless the standard specifically permits it, 29 CFR 1910.305 prohibits using flexible cords and cables:
Flexible cords must also be used in continuous lengths without splice or tap. Hard-service and junior hard-service cord No. 14 and larger may be repaired only with a splice that keeps the insulation, outer sheath properties and usage characteristics of the original cord. Around panels, the working space required by 1910.303 may not be used for storage, and for equipment operating at 600 volts or less it must be at least 30 inches wide or the width of the equipment, whichever is greater.
A short electrical walkdown catches most of this: extension cords serving permanent equipment, cords pinched in doors or stapled to walls, damaged insulation, open knockouts in boxes, and boxes or carts parked in front of panels.
Housekeeping is a fire control, not a cosmetic one. The fire prevention plan elements in 1910.39 include procedures to control accumulations of flammable and combustible waste, which means defining who removes what, how often and into which containers. Many facilities, for example, use self-closing metal containers for oily rags and set disposal frequencies by area rather than leaving it to whoever notices the pile.
Clutter becomes a citation risk when it reaches an exit route. Under 29 CFR 1910.37, exit routes must be free and unobstructed, and no materials or equipment may be placed in an exit route, either permanently or temporarily. The word temporarily is where many sites slip: a pallet staged for an hour, a cart parked during a delivery or a rack of returns in a corridor still counts. The same standard requires exit routes to be kept free of explosive or highly flammable furnishings and decorations, and exit route doors to be free of decorations or signs that obscure them.
Hot work is any work that produces flame, sparks or heat capable of igniting combustibles, such as welding, cutting and brazing. OSHA's general industry rule, 29 CFR 1910.252, sets a clear order of precedence: if the object cannot be moved to a safe place, move the fire hazards away from it; if the fire hazards cannot be removed, use guards to confine heat, sparks and slag; and if neither is possible, welding and cutting must not be performed.
Before cutting or welding is permitted, the individual responsible for authorizing it must inspect the area and designate the precautions to follow, preferably in a written permit. Key requirements include:
A fire watch is required whenever welding or cutting is done where other than a minor fire might develop, or where any of these conditions exist: appreciable combustibles closer than 35 feet to the point of operation; appreciable combustibles farther than 35 feet but easily ignited by sparks; wall or floor openings within 35 feet that expose combustibles in adjacent areas, including concealed spaces; or combustibles on the opposite side of metal partitions, walls, ceilings or roofs that could ignite by conduction or radiation. Fire watchers must have extinguishing equipment readily available, be trained in its use and know how to sound the alarm.
This is the detail the advice to never leave hot work unattended misses. The 1910.252 requirement continues after the torch is off: the fire watch must be maintained for at least a half hour after welding or cutting is completed, to detect and extinguish smoldering fires. 1910.252 incorporates the 1962 edition of NFPA 51B by reference, and newer editions of NFPA 51B call for a longer post-work watch. Your insurer or local fire code may hold you to that longer period.
Where EHS Insight fits: The Permitted Work module replaces paper permits with a controlled workflow. A Work Permit is submitted, moves through your configured approval levels, stays active while work is underway and is closed when the work is complete. A Safety Reviews grid lets you associate JSAs, SOPs and other supporting documents, and permits can be assigned to internal users or to vendor workers, who access them through the Vendor Portal.
For portable fire extinguishers provided for employee use, 29 CFR 1910.157 sets a layered schedule. The employer is responsible for the inspection, maintenance and testing of every portable extinguisher in the workplace:
Placement matters as much as condition. Extinguishers must be mounted, located and identified so they are readily accessible, with a travel distance of 75 feet or less to an extinguisher for Class A fires and 50 feet or less from a Class B hazard area. Note one gap in the federal text: OSHA requires a record of the annual maintenance date but does not separately spell out a record for the monthly check. Without a dated tag or log, though, you have no way to show an inspector or insurer that the monthly inspection happened.
The standard also has a trigger most generic checklists skip. If you have a written policy requiring immediate and total evacuation when the fire alarm sounds, backed by an emergency action plan and fire prevention plan that meet 1910.38 and 1910.39, and extinguishers are not available in the workplace, you are exempt from 1910.157 unless another standard requires extinguishers. If extinguishers are present but not intended for employee use, and you have both plans, the inspection, maintenance and hydrostatic testing requirements still apply.
Training follows the same logic. Where you provide extinguishers for employee use, you must provide an educational program on the general principles of extinguisher use and the hazards of incipient stage firefighting, upon initial employment and at least annually after that. Beyond extinguishers, 1910.37 requires safeguards such as sprinkler systems, alarm systems, fire doors and exit lighting to be in proper working order at all times.
Where EHS Insight fits: With the Compliance Tasks module, you can schedule recurring Inspection tasks on a daily, weekly, monthly or yearly pattern, assign them to a person, a role or one or more Business Entities, and send reminders and escalation notifications for upcoming or overdue tasks, all visible on the Compliance Calendar (solution brief). Start each inspection form from the task in My Tasks or the calendar so the record is associated with the task. The Audit & Inspection module supports on-site data capture and lets you assign corrective actions directly from findings, and Training Management helps you track employee completion of required training. For more on building an inspection program, read Achieving EHS Compliance With Audits and Inspections.
Prevention reduces fires; it does not eliminate them. OSHA's emergency action plan standard, 29 CFR 1910.38, applies whenever another OSHA standard requires an emergency action plan (EAP), including the extinguisher exemptions described above. Like the FPP, it must be written, kept in the workplace and available to employees, unless you have 10 or fewer employees and communicate it orally. At a minimum, an EAP must include:
You must also have and maintain an employee alarm system that uses a distinctive signal for each purpose and complies with 1910.165, and you must designate and train employees to assist in a safe and orderly evacuation of others.
Review is event-triggered, not calendar-based. You must review the EAP with each covered employee when the plan is developed or the employee is initially assigned to a job, when the employee's responsibilities under the plan change, and when the plan is changed. 1910.38 does not set a drill frequency. Many employers drill on a fixed schedule anyway, and local fire codes, State Plans or insurers may require it, because a drill is the only way to find out whether the reporting, evacuation and accounting procedures work as written. Floor plans with exits and assembly areas marked, and posted emergency contacts, are common additions that make the required procedures usable.
Where EHS Insight fits: The Safety Drill module documents when and where each drill occurred and the drill type, plus details such as response teams, equipment used, post-drill meeting notes and lessons learned, depending on how the drill type is configured. When a drill exposes a gap, you can create a corrective action directly from the form and track it to completion with the CAPA module. When the plan changes, the Awareness & Accountability module can distribute the updated document and capture each employee's acknowledgment.
The seven practices overlap by design. The hazard inventory in your FPP drives which areas need extinguishers, which equipment needs maintenance safeguards and where hot work needs extra precautions. Inspection findings feed corrective actions. Drill results feed plan changes, and plan changes trigger employee reviews. A common weak point is the handoff between those steps, when a finding or a due date sits in someone's inbox.
Tying each obligation to an owner, a due date and a record closes those gaps. EHS Insight's Legal Register module gives you a centralized place to track, review and manage the regulatory obligations that apply to your sites, including the standards named in this article. If you need a starting point for corrective action documentation, download the CAPA template.
Only when another OSHA standard requires one. When it does, 29 CFR 1910.39 requires the plan to be written, kept in the workplace and available to employees, unless you have 10 or fewer employees, in which case you may communicate it orally. A common trigger is the portable fire extinguisher standard, 29 CFR 1910.157: its exemptions for employers who rely on evacuation instead of employee firefighting depend on having an emergency action plan and a fire prevention plan that meet 1910.38 and 1910.39.
Under 29 CFR 1910.157, portable fire extinguishers need a visual inspection every month and a maintenance check every year, and you must record the annual maintenance date. Stored-pressure dry chemical extinguishers that require a 12-year hydrostatic test must also be emptied and maintained every 6 years, and hydrostatic testing is due every 5 or 12 years depending on the extinguisher type listed in Table L-1 of the standard.
Under OSHA's general industry welding standard, 29 CFR 1910.252, a fire watch, when one is required, must be maintained for at least a half hour after welding or cutting is completed. Newer editions of NFPA 51B, the consensus standard for hot work fire prevention, call for a longer post-work watch, and your insurer or local fire code may require that longer period.
No. Under 29 CFR 1910.157, the education requirement applies where you provide portable fire extinguishers for employee use, and those employees need it upon initial employment and at least annually after that. Employees designated to use firefighting equipment under an emergency action plan need training in that equipment upon initial assignment and at least annually after that.
OSHA's emergency action plan standard, 29 CFR 1910.38, does not set a fire drill frequency. It requires you to train the employees designated to assist in evacuation and to review the plan with each covered employee when the plan is developed or the employee is first assigned, when their responsibilities under the plan change and when the plan changes. Local fire codes, State Plans and insurers may require drills, and many employers run them as a practical test of the plan.
