A fire extinguisher is often the first line of defense for a fire. There are different types of extinguishers for different types of fires. The most common fire extinguisher for the home is the ABC extinguisher. This extinguisher can be used on ordinary combustibles (paper, wood, etc.), liquids(grease, fuels, etc.) and fires involving electricity (electronics, outlets, etc.). Twice a year, turn your fire extinguishers upside down and tap the bottom to prevent the dry chemicals from caking. Return it to service.
The relatively new, K extinguishers are designed specifically for kitchen fires and the fuels involved. If you have any questions as to the condition of your fire extinguisher, contact a fire suppression supplier/service company to inspect or replace older extinguishers.
And remember PASS: Pull/Aim/Squeeze/Sweep (PULL the pin, AIM at the base of the fire, SQUEEZE the handle, and slowly SWEEP side to side)
