The following diagram helps summarize the class “B” requirements contained within the ANSI/UL-711 standard, showing the relationship between actual fire test pan sizes and minimum effective hardware discharge time requirements necessary for obtaining each numerical fire rating. It has a moderate spray range and last only 10 to 30 seconds. Such schools utilize leading industry experts as instructors to effectively train thousands of municipal and industrial firefighters from around the world on how to properly address various flammable liquid fire situations with extinguishers. At that time, extending the minimum discharge durations for the larger fires was believed necessary, to help dictate the selection and utilization of larger extinguisher sizes. A wall bracket is included with each extinguisher. When burning liquid fuels surround obstacles, they present a condition where the utilization of the proper extinguishing agent and hardware become critical. The UL rating is broken down into Class A and Class B:C ratings. Because most emergency response fire situations involving the accidental release of liquid fuels will likely present potential obstacle situations, the hand portable extinguisher models professional firefighters, fire brigades, and emergency response team members prefer will have agent discharge flow rates of between 1 to 2 pounds per second. Fire extinguisher installations are also limited to protruding no more than 4 inches into the adjacent path of travel.
