- Air_pressurized_water abstract "Air pressurized water or APW extinguishers are types of fire extinguishers that extinguish burning material by absorbing heat. They contain 2.5 US gallons (9.5 L) of water or water with a wetting agent which is applied by means of a ½-inch hose with a smooth-bore nozzle attached to the tip. They will initially produce a 40–50 foot stream of water, with a discharge time of about 50 seconds. Although only effective on only Class A fires, they have the advantage of being inexpensive to operate and causing minimal damage and clean-up. Also known as a water cans, they are commonly converted into makeshift CAFS extinguishers by drilling two 1/8–1/16 inch holes in the pickup tube. The unit is then filled with 1.5 US gallons (5.7 L) of water and Class A foam, AFFF, FFFP or commercial detergent is added to the water in a 1% ratio for class A fires and a 3–6% ratio for Class B fires. Typically, the tip of the smooth-bore application nozzle is then cut off to allow the foam to properly expand. Keeping the nozzle will result in wetter foam and longer range. Cutting the nozzle will result in an expanded, dry foam but will lack the range of the standard water nozzle. Water extinguishers can also be fitted with air aspirators when used with foam (commonly used on AFFF and FFFP foam extinguishers) which will result in a more expanded foam but will lack the durability or heat resistance of compressed air foam.".
