- You have been trained.
- You have the proper type and properly charged unit for the fire you are fighting.
- You have first contained the fire, activated the building alarm and have reported the fire.
- You have your back to an unobstructed exit.
- Everyone else has left the area.

Never fight a fire if it has left its source of origin, you are unsure of the type of extinguisher you are using or you lack a safe way to escape should your efforts fail. If the fire can not be brought under control in 30 seconds, then abandon your efforts, close the door(s) and evacuate immediately.
