In addition, there are specialty extinguishers which are available in specific locations for special hazards.
Water weighs eight and one-third lbs.
The maximum range is 30-40 feet and the approximate time of discharge is 1 minute. The extinguisher is equipped with a pressure gauge which indicates if the extinguisher is charged. Pressurized water are to be used on Class A fires only. The total weight of the extinguishers ranges from 15 to 40 lbs. CO2 extinguishers are not equipped with pressure gauges and therefore must be weighed to determine if the extinguisher is fully charged.
