The “Pyrofoam” Fire Extinguisher
“Pyrofoam” is a fire extinguisher manufactured by the Pyrofoam Company, whose office and factory is at 126 North Union street, Chicago, Ill. The company claims it is the only foam fire extinguisher having a sealed inner container, which avoids recharging until it is used. To operate the Pyrofoam extinguisher it is turned bottom up and the plunger on the floor. This breaks the seal of the inner container and throws the contents into contact with the larger body of chemical in the tank proper, and a stream of carbonic gas foam is thrown a distance of 50 feet.
