OSHA Fire Extinguisher Requirements — 1910.157 Compliance Guide

OSHA's 1910.157 standard requires employers to provide, inspect, and maintain portable fire extinguishers. Here's what every business owner — and every fire protection contractor — needs to know.

What OSHA 1910.157 requires

OSHA's standard for portable fire extinguishers (29 CFR 1910.157) applies to all employers who provide fire extinguishers for employee use. If you have extinguishers in your workplace, these rules apply.

1. Inspection (1910.157(e)(2))

Portable extinguishers must be visually inspected monthly. The inspection must verify:

• Extinguisher is in its designated place
• No obstruction to access or visibility
• Operating instructions are legible and face outward
• Safety seals and tamper indicators are intact
• No obvious physical damage or corrosion
• Pressure gauge reading is in operable range
• Fullness determined by weighing or hefting

2. Maintenance (1910.157(e)(3))

Extinguishers must undergo annual maintenance checks performed by a certified technician. Records of annual maintenance must be kept — either on the extinguisher tag or in an electronic log.

3. Hydrostatic Testing (1910.157(f))

Extinguishers must be hydrostatically tested at intervals specified by the manufacturer or the DOT, typically every 5 or 12 years depending on the extinguisher type.

4. Mounting and Location (1910.157(c))

Extinguishers must be mounted on brackets or in cabinets with the carrying handle no more than 3.5 feet to 5 feet from the floor (depending on extinguisher weight). They must be located along normal paths of travel and near exits.

5. Training (1910.157(g))

If employers expect employees to use fire extinguishers, they must provide training at initial employment and at least annually. If employers designate specific employees to evacuate rather than fight fires, different rules apply.

OSHA penalties for non-compliance

OSHA fines for 1910.157 violations range from $1,000 to $16,131 per violation (2026 maximums). Willful or repeated violations can reach $161,323. Beyond fines, non-compliance creates serious liability exposure if a fire occurs and extinguishers aren't functional.
