Use Fire Extinguisher Properly: Step by Step

To use a fire extinguisher it's required to follow 4 easy steps, It's PASS:

By removing the pin fire extinguisher is ready to use.

Aim the hose at the base of the fire: After removing the safety pin you have to aim it's hose at the base of the fire because the fire can extinguish properly if the media discharged on the base of the fire not on the flames of the fire.
