Picture of Fire Engine from 1890

STOP DROP AND ROLL
An important part of fire safety is, knowing what to do if your clothes, or the clothes of someone you are with, catch fire. The most efficient way of extinguishing the fire it to:
Stop Drop Roll
     
Stop what you are doing. Do not try to pat the fire or run. Drop to your knees and lie down on the floor on your stomach. Close your eyes and cover your face and mouth with your hands to protect yourself from flames and smoke, and roll over until the flames are out.
