This has the added power of expanding over eight times its bulk in the container when released, so that if the house type is used the container need not be over ³⁄₄ gallon and you really have about six gallons of material for the fire. This does no more damage to draperies than would water. It does not injure cottons or wools and does not penetrate fabrics as many other chemicals do. If it gets on one’s clothes it is easily brushed off after it dries. On polished and varnished furniture it has no effect and is easily washed off. SERVICE Reliable firms will always tell you correctly what kind of an extinguisher to buy for your particular purpose. They will, too, in compliance with the Board of Underwriters’ rulings, watch the apparatus once a year and recharge if necessary. Actually they don’t always need it, but it is a wise ruling of the Board. There are some extinguishers excellent for outdoors, motor boating, etc., but which indoors are apt to give off suffocating fumes. There are extinguishers of large capacity on wheels for large homes and large estates. These are a great insurance against fire. They are built on narrow gage wheels for rolling on floors in the house and heavier construction for outdoor use. Many big estates use these little two wheelers, as they are fire departments in themselves. A good quality fire hose is a mighty good assistance in a large home, too, and is becoming very widely used. Of course, there are many fires that water not only will not quench, but will spread; on the other hand, there are many little conflagrations that water immediately will kill. Another good method, but not as efficient, for use in all conditions is the telescopic fire bucket set. Six pails are set in a container in the liquid and all one has to do in case of fire is to open the lid and each pail comes out filled. If the fire is not great and has just started and is within a few feet of you, this is all well and good, but one can hardly throw water from a pail as far as ten feet above your head, while with the extinguisher the stream is from twenty to forty feet in length. This pail system would not reach a roof, you see, which the extinguisher might. An intimate acquaintance with the wizardly asbestos will do a lot in the home to keep the hearth fires burning in their right places. The asbestos ironing pad on the ironing board is a good resilient thing. Although not in this case primarily meant as a fire preventive, it will stop the iron from causing a big fire, even if it should burn off the top sheeting, for when it reaches the asbestos the fire will go out. There are now some very convenient collapsible ladder escapes which are stored in a small box near the window, which makes the escape from a fire not dependent on ancestors who were tight-rope walkers.
