Fire Extinguisher 43
Fire Extinguisher 43 : Maintenance: In the United States there are 3 types of service as well: (1) Maintenance Inspection: All types of extinguishers should be inspected at least once a year. The extinguisher is checked to make sure it has proper pressure (gauge in green or proper cartridge weight), has the correct volume of extinguishing agent (tech weighs it), is within the required hydrotest and internal maintenance intervals, is in good condition and all external parts are serviceable. Often, dry chemical and dry powder types are hit on the bottom with a rubber mallet to make sure the powder is free-flowing, which is called "fluffing" the powder. The tech will then attach a new tamper seal around the pin and a yearly service tag
