Write the instruction to use a fire extinguisher

Firstly, pull the pin on the fire extinguisher. Aim the nozzle on the hose low, toward the base of the fire. Next, squeeze the handle or lever to discharge the extinguisher. Sweep the nozzle back and forth. Keep the fire extinguisher aimed at the base of the fire and move it from side to side until the flames are extinguished. You should stay between six and eight feet away from the flames. If there is the slightest doubt or uncertainty about tackling the fire evacuate the building immediately and call the fire brigade.
