Fire Extinguisher Location Signs | Clarion Safety Systems

Q: "Are fire extinguisher signs required by OSHA?"

"OSHA 29 CFR 1910.157(c)(1) requires portable fire extinguishers to be mounted, located and identified so they are readily accessible. Signs are the standard way to satisfy the identification requirement, and NFPA 10 provides guidance on marking locations where the extinguisher is not clearly visible."

Q: "Where should a fire extinguisher sign be mounted?"

"Mount the sign above the extinguisher, high enough to be seen over equipment, racking and people from the areas it serves. In long aisles, projecting or flag-style signs keep the location visible down the full corridor."

Q: "What does the ISO fire extinguisher symbol look like?"

"The ISO 7010 F001 symbol shows a white fire extinguisher on a safety red square. It identifies fire equipment locations without any text and is recognized internationally."

Fire Extinguisher Signs That Make Locations Visible When Seconds Count

Fire extinguisher signs are among the most numerous safety signs in workplaces and public buildings, and among the most important to get right. OSHA's portable fire extinguisher standard, 29 CFR 1910.157(c)(1), requires extinguishers to be mounted, located, and identified so that they are readily accessible to employees. A fire extinguisher location sign is the most direct way to meet that identification requirement, especially in large spaces, cluttered environments or areas where the extinguisher itself is not visible from a distance. NFPA 10, the Standard for Portable Fire Extinguishers, adds guidance on marking extinguisher locations where visual obstructions cannot be avoided.

Modern Symbol-Based Design for Faster Recognition and Fewer Missed Extinguishers

Most fire extinguisher signs in service today still use arrow-with-text designs that date back generations. Clarion Safety's fire extinguisher signs instead use the internationally standardized fire extinguisher symbol, F001 in ISO 7010: a white extinguisher on a safety red square. The symbol is recognized at a glance and across languages, which matters most in the moments when someone is searching for an extinguisher under stress.

Fire extinguisher sign formats include:

Wall-mounted location signs positioned above the extinguisher for long sightlines

Projecting and flag-style signs visible down aisles and corridors

Photoluminescent options that stay visible in smoke and power loss conditions
