NFPA 170-2018 PDF Download

The NFPA 170-2018 standard aims to standardize fire safety symbols for improved communication. It provides designers, engineers, architects, and emergency planners with essential information on uniform symbols used for fire safety, emergencies, and associated hazards.

The new edition of NFPA 170 includes several updates and revisions to enhance clarity and consistency. One notable change is the introduction of a new symbol for tornado, which helps to convey this specific hazard. The standard also includes updated references, revised terms such as "smoke barrier" being changed to "smoke rated" and "fire barrier" being changed to "fire rated," and additional details for symbols representing a fire department connection.

NFPA 170 is intended to facilitate better communication between building occupants, designers, installers, and first responders. It is a crucial resource for the fire service, architectural and engineering drawings, insurance diagrams, firefighting operations, and pre-incident planning sketches. The standard's annexes provide additional explanatory material and symbols for life safety planning.
