1.1 Scope. This standard presents symbols used for fire safety, emergency, and associated hazards.
NFPA 170 provides standard symbols used to communicate fire safety, emergency, and associated hazards information. Using easily understood uniform symbols on labels and signs provides consistency, eliminates confusion, and improves communication.
This standard is intended for the general public and the fire service, as well as for architectural and engineering drawings, insurance diagrams, fire fighting operations, and pre-incident planning sketches. It includes symbology for emergency management mapping, and emergency evacuation diagrams and plans. Annexes provide explanatory material and symbols for life safety planning.
