If you should catch on fire:
STOP - where you are
DROP - to the floor
ROLL - around on the floor
This will smother the flames, possibly saving your life.
If someone else catches on fire, smother the flames by grabbing a blanket
or rug and wrapping them up in it. If a fire extinguisher is available, use it to
extinguish the flames. That could save them from serious burns or even death.
