Fire Extinguishers
Always maintain 3 feet of clearance around all fire-protection equipment. Never re-hang a fire extinguisher once it has been used. Have it recharged by a licensed service provider. Most of all, practice fire prevention and good housekeeping. Don’t give fire a place to start.
Class A
Any fire involving ordinary combustible materials such as paper, wood, cloth, rubber and plastics. Extinguish with a penetrating cooling agent. Water is the best material commonly available for this.
Class B
Any fire involving flammable liquids, such as gasoline, naphtha, acetone, greases and oils; or flammable gases like methane or hydrogen. Extinguish with surface-acting agents such as dry chemicals, which break up the chemical reaction of the fire; or use inert, dense, heavier-than-air gases, which smother the fire.
Class C
Any fire involving electrical equipment, appliances and wiring. Extinguish with a nonconductive extinguishing agent to protect against electrical shock. Most extinguishers that have a Class B rating also have a Class C rating, but read the label to be sure.
Class D
Any fire involving combustible metals such as magnesium, lithium, potassium, etc. would be considered a Class D Fire
