Fire Signs

According to NFPA 101 Life Safety Code, externally illuminated exit signs must have a minimum surface illumination of 5 foot-candles (54 lux). Internally illuminated signs must be UL 924 listed to meet performance and safety standards. This required brightness ensures exit signage remains clearly visible, even in smoke-filled conditions or during partial power loss. You can explore compliant illuminated exit signs to meet these code requirements.

NFPA 10 requires fire extinguishers to be “conspicuously located” so they are easy to find during an emergency. If an extinguisher is obstructed or stored inside a cabinet, a clearly visible fire extinguisher sign should be mounted directly above it. In most facilities, signs are typically installed 60 to 80 inches from the floor to ensure visibility over equipment or obstacles. Proper placement of fire safety signs helps improve response time and maintain code compliance.

Yes, OSHA 29 CFR 1910.37(b)(5) requires that any door or passage along an exit route that could be mistaken for an exit must be clearly marked “Not an Exit” or labeled with its actual use (such as “Closet” or “Storage”). Posting proper Not an Exit signs and maintaining accurate exit route signage helps prevent confusion and dangerous dead ends during an emergency evacuation.

Under NFPA 80, signage placed on a fire door must not exceed 5% of the total door surface area and must be attached using adhesive only. Mechanical fasteners such as screws or nails are prohibited because they penetrate the door’s protective core and can compromise its fire rating. To remain compliant, facilities should use properly rated fire door signs and follow approved installation guidelines for all fire safety signage.
