The Nasdco Breathing Helmet

The Nasdco Breathing Helmet

The Nasdco breathing helmet to enable firemen to enter a room filled with noxious gases, fumes or smoke to save life or property, or to stop the source of the fumes and locate and extinguish fire is based on the principle that in every building filled with smoke or fumes there is a cushion of pure air near the floor. The wearer inhales this air through a trailing tube and exhales through an opening in the top of the helmet. The manufacturers, the National Safety Device Company, Cleveland, O., state that this device has been adopted by fire departments in more than one hundred cities in the United States during the past year. The weight of the helmet is about 3 1/2 pounds, and it can be put on in seven seconds. The wearer can see, speak, and hear and has full use of his hands and feet. An example of what has been done with this breathing device and smoke protector is given in a letter to the manufacturers from B. F. Sturdevant, of the Jamestown, N. Y., fire department, in which he says: “At the fire in the Hotchkiss block which occurred November 20, 1913, and was considered one of the smokiest fires ever occurring in Jamestown, burning out the P. M. Johnson dry goods store, I wore your helmet. At this fire I used about 40 gallons of chemicals, which consumed about 20 minutes. I also wore this helmet to locate a fire in the Pearl City Veneer Company’s plant, Novmber 30 last, with success. This, too, was an exeedingly smoky fire. I extinguished the fire with chemicals while wearing the helmet.”
