This edition includes:  The all-new symbol for tornado Updated references Revised terms, including smoke barrier changed to smoke rated, and fire barrier changed to fire rated Added details to the symbols for a fire department connection A distinction between water-driven and electric-driven water flow alarms Use NFPA 170 to improve communication between building occupants, designers, installers, and first responders.  This edition is essential for the fire service, as well as for architectural and engineering drawings, insurance diagrams, fire fighting operations, and pre-incident planning sketches.
