Such drills would undoubtedly prevent much loss of life when 

 large fires occur. 



Fire Prevention. Fires may often be prevented by due 

 caution on the part of those in charge of buildings. Often fires 

 start from lamps or small 

 stoves that explode because 

 they are not properly cleaned. 

 The person in charge should 

 see that they are kept in good 

 condition. He should never 

 allow kerosene or other in- 

 flammable liquid to be poured 

 on fuel already ignited. He 

 should examine all chimney 

 flues and all heat pipes leading 

 from a furnace to make sure 

 that they are in good order be- 

 fore he builds a fire. 



Fire Extinguishers. In 

 spite of all precautions, dra- 

 pery or other material in a 

 room will sometimes acciden- 

 tally catch fire. In such cases, 

 the use of a fire extinguisher 

 will often prevent the spread of 

 the flames. Everyone should 

 understand the structure, prin- 

 ciple and use of this safety 

 apparatus. 



Experiment to Show 

 Structure and Use of a Fire 

 Extinguisher. A good way to learn about a fire extinguisher 

 is to make one and use it. This may be done with a wide- 

 mouthed bottle, a solution of bicarbonate of soda, a test tube, 

 some sulphuric acid, a one-hole rubber stopper for the wide- 

 mouthed bottle, a glass tube, a few feet of rubber tubing, a tin 

 can, match sticks and paper.
