is inverted, the acid mixes with the soda and produces 

 carbon dioxide gas. The gas is confined and creates 

 such great pressure that the liquid is forced out the hose 

 to a distance of 40 to 50 feet. The water which escapes 

 is charged with carbon dioxide and 

 has some soda in it. All these sub- 

 stances are good fire extinguishers. 

 The flow of liquid may be stopped at 

 any instant by inverting the extin- 

 guisher. But after once inverting, it 

 must be recharged at once. This is 

 the kind of extinguisher for the house, 

 since the suffocating gas is less than 

 in case of the volatile gas extin- 

 guisher which is used in the garage. 



Safety first. If you get caught in 

 a burning building and the fire has 

 made such headway as to be a serious 

 menace to you, it is your first duty 

 to save your life. It is well to be 

 prepared for any emergency and to 

 know in advance just what to do.

to pass through a smoke-filled room, 

 tie a wet cloth over the nose and mouth to absorb the 

 smoke and crawl on the floor as there is less smoke near 

 the floor. If you think you must jump from a window, 

 throw out pillows, cushions, and mattress to land on 

 and jump only if forced to it. Bed clothing may be tied 

 into a rope on which to climb to safety. Above all keep 

 cool.
