involving paper, wood, and other common accoutrements.
2. Froth
extinguishers these use a admixture of water and froth to smother fires.
They’re effective for fires involving liquids like gasoline and oil painting.
3. Carbon dioxide (CO2)
extinguishers these use CO2 to displace the oxygen that’s fuelling the fire.
They’re effective for electrical fires and fires involving ignitable liquids.
4. Dry greasepaint
extinguishers these use a fine greasepaint to smother the fire and help it from
spreading. They’re effective for a variety of fires, including those involving
ignitable liquids, feasts, and essence.
