Firefighting Decision Criteria
• Know department emergency procedures
  and evacuation routes.
• Know locations of extinguishers in your
  area and how to use them.
• Always sound the alarm regardless of fire
 size.
• Avoid smoky conditions.
• Ensure area is evacuated.
• Don’t attempt to fight unless:
   - Alarm is sounded.
   - Fire is small and contained.
   - You have safe egress route (can be reached
   without exposure to fire).
   - Available extinguishers are rated for size
     and type of fire.
• If in doubt, evacuate!
