KEY TAKEAWAYS Fire safety at work requires a written OSHA 1910.39 fire prevention plan, a 1910.38 emergency action plan, Class ABC extinguishers within 75 feet of workers, two marked exit routes, and documented training. 2024 NFPA data: 1.39M U.S. fires, 3,920 deaths, $19.1B damage. 2026 OSHA willful violations reach $165,514. |
Friday night, 11:47 PM. An overloaded power strip shorts under an empty accounting office desk. By 2 AM, the server room is gone. Fourteen years of client records. Gone. Insurance covers 60% of a six-month rebuild.
The power strip cost $7. A surge-protected UPS with thermal shutoff costs $120. That’s the entire gap between workplaces that burn and those that don’t: a few hundred dollars and two or three written procedures.
Three required pillars of workplace fire safety: a written Fire Prevention Plan (OSHA 1910.39), a written Emergency Action Plan (OSHA 1910.38), and documented employee training. Workplaces with 10 or fewer workers can maintain plans orally. 11+ must keep them in writing. |
What is fire safety at work?
Fire safety at work is the combined set of engineering, administrative, and training controls U.S. employers use to prevent workplace fires, detect them early, suppress them, and evacuate workers safely. OSHA regulates it through 29 CFR 1910 Subparts E and L, with NFPA 101 as the underlying consensus standard. |
Four domains matter: prevention, detection, suppression, evacuation. OSHA sets the federal floor. NFPA develops the consensus standards that state and local codes adopt.
Standard | Covers | Applies to |
29 CFR 1910.38 | Emergency Action Plans (EAP) | Required employers |
29 CFR 1910.39 | Fire Prevention Plans (FPP) | 11+ employees |
29 CFR 1910.36/37 | Exit route design and maintenance | All general industry |
29 CFR 1910.157 | Portable fire extinguishers | Any workplace with extinguishers |
NFPA 101 | Life Safety Code (egress, occupancy) | Referenced by OSHA |
NFPA 10 | Portable extinguisher standard | Referenced by OSHA 1910.157 |
NFPA 72 | Fire alarm and signaling systems | Commercial buildings |
Fire safety compliance in 2026: what has changed
2026 OSHA fire safety violations carry up to $16,550 per serious citation and $165,514 per willful or repeat violation. Three NFPA code updates take effect: NFPA 10 2026 permits electronic extinguisher monitoring, NFPA 72 2025 requires cybersecurity for networked alarms, and NFPA 855 2026 expands lithium-ion battery storage rules. |
Missing fire prevention plans, blocked exits, or undocumented extinguisher inspections each write as serious citations at $16,550. Each becomes willful at $165,514 if the inspector finds prior knowledge.
Three 2026 NFPA changes that matter
NFPA 10 (2026): Electronic monitoring of portable extinguishers now permitted as an alternative to manual inspection. Monthly manual checks still required until local adoption.
NFPA 72 (2025): Chapter 11 now requires formal cybersecurity procedures for network-connected fire alarm systems.
NFPA 855 (2026): Expanded rules for lithium-ion battery storage, including energy storage systems, warehouse battery rooms, and EV charging. Fire testing aligned to UL 9540A.
“Employers who invest in safety training and maintain documented programs consistently see lower severity determinations during inspections.” — Scott Ketcham, Director, OSHA Directorate of Enforcement Programs, NSC Congress, September 2024 |
Where U.S. workplace fires actually happen
NFPA 2024 data: 1.39 million U.S. fires, 3,920 civilian deaths, $19.1 billion in property damage. A fire department responded every 23 seconds. Nonresidential fires: ~110,000 annually (16,500 office/store, 36,700 industrial/manufacturing, 1,500 warehouse, plus ~10,000 restaurant fires). |
Facility type | Annual fires | Leading cause |
Industrial / manufacturing | 36,700 | Electrical, hot work, machinery |
Office / store | 16,500 | Cooking, electrical, heating |
Restaurant | ~10,000+ | Cooking equipment |
Healthcare | ~7,000 | Cooking, electrical, smoking |
Warehouse | 1,500 | Electrical, combustibles |
Electrical fires caused 7,400 nonresidential fires in 2023 and $354.4 million in losses. That is roughly $48,000 per incident before business interruption. Cooking starts ~29% of office fires but accounts for only 6% of damage. Electrical and heating fires are what actually destroy offices.
The 7 essential fire prevention practices
The seven essential workplace fire prevention practices are: written fire prevention and emergency action plans, proper flammable storage, quarterly electrical inspections, hot work permits, extinguishers within 75 feet, functional alarms, and documented employee training plus annual fire drills. |
# | Practice | Standard |
1 | Written Fire Prevention Plan: hazards, ignition sources, named responsibilities | OSHA 1910.39 |
2 | Written Emergency Action Plan: evacuation, accountability, chain of command | OSHA 1910.38 |
3 | Flammable storage: approved cabinets, separated oxidizers, daily waste removal | NFPA 30 |
4 | Electrical safety: quarterly inspections, 36″ panel clearance, no daisy chains | NFPA 70E |
5 | Hot work permits: fire watch, 35-ft clearance, extinguisher on site | NFPA 51B |
6 | Portable extinguishers: 75 ft for Class A, 50 ft for Class B, monthly inspection | OSHA 1910.157 |
7 | Training & drills: hazard-specific, annually, documented | OSHA 1910.38(e) |

The fire extinguisher class matrix
Fire extinguishers come in five classes: A (ordinary combustibles), B (flammable liquids), C (electrical), D (combustible metals), and K (cooking oils). Most offices need Class ABC multi-purpose. Commercial kitchens require Class K at every cooking station. Wrong class spreads fire or electrocutes users. |
Class | Fuel | Where required |
A | Wood, paper, cloth, plastic | All workplaces |
B | Gasoline, oil, solvents | Garages, industrial |
C | Energized electrical equipment | All workplaces (ABC) |
D | Magnesium, titanium, lithium | Specialty manufacturing |
K | Cooking oils and fats | Commercial kitchens |
The PASS technique
- Pull the pin to release the handle.
- Aim at the base of the fire, not the flames.
- Squeeze the handle in a steady motion.
- Sweep side to side across the fuel base.
WHEN NOT TO USE AN EXTINGUISHER If the fire is larger than a wastebasket, has reached the ceiling, fills the room with smoke, or threatens your exit, evacuate. Extinguishers handle incipient fires only. |
Fire hazard prevention by industry
Fire risk varies by industry. Offices focus on electrical and cooking. Manufacturing targets hot work and machinery. Warehouses control ignition near combustibles. Healthcare uses defend-in-place. Restaurants require Class K plus hood suppression. Construction demands hot work permits and fire watches. |
Industry | Top risk | Priority control |
Office | Electrical, break room cooking | Quarterly electrical inspection, ABC extinguishers |
Manufacturing | Hot work, combustible dust | Hot work permits, dust housekeeping |
Warehouse | Electrical, palletized combustibles | Sprinkler inspection, storage limits |
Healthcare | Cooking, electrical, medical gases | Defend-in-place, quarterly drills |
Restaurant | Cooking oils, grease | Class K, hood suppression, duct cleaning |
Construction | Hot work, combustible debris | Hot work permits, fire watch |
“Today’s fire, life, and electrical safety environment is complex. Never has the need for safety to accompany societal progress been so paramount.” — Lorraine Carli, VP Outreach and Advocacy, NFPA, U.S. Fire Administrator’s Summit, October 2024 |
Exit route compliance
OSHA 1910.36 requires minimum two exit routes per workplace, 28-inch clear door width, illuminated EXIT signs with 6-inch letters, outward-swinging doors unlocked from inside, and 90-minute emergency lighting. Exits must lead outside. Fire-rated separation: 1-hour for 3 stories or fewer, 2-hour for 4+. |
- Minimum 2 exit routes, more if occupancy demands it
- Minimum 28″ door width, 36″ corridor width
- Illuminated EXIT signs, 6″ letters, 3/4″ strokes
- Emergency lighting, 90-minute operation on power loss
- Outward-swinging doors in rooms with 50+ occupants
- Unlocked from inside during occupied hours
- Fire-rated: 1-hr for ≤3 stories, 2-hr for 4+
- Nothing blocks the exit. Ever.
THE PROPPED FIRE DOOR TEST A fire-rated door propped open with a wedge, extinguisher, or furniture is an automatic citation. Magnetic hold-opens tied to the alarm system are permitted because they release on activation. |
The most common OSHA fire safety violations
The most frequently cited fire safety violations are blocked exit routes, locked exit doors, expired extinguisher inspections, missing Fire Prevention Plans, propped-open fire doors, and lack of training documentation. Each can be cited at $16,550 serious or $165,514 willful under the 2026 OSHA penalty schedule. |
Violation | Standard |
Blocked exit route | 1910.37(a)(3) |
Locked exit door during occupied hours | 1910.36(d)(1) |
Missing or unlit EXIT sign | 1910.37(b)(2) |
Extinguisher past inspection date | 1910.157(e)(3) |
No written Fire Prevention Plan | 1910.39(b) |
No written Emergency Action Plan | 1910.38(b) |
