Every home should have at least one fire extinguisher, lodging in the kitchenBetter still is to install fire extinguishers on each level of a house and in each potentially hazardous area, including (besides the kitchen) the garage, hearth room, and workshop.

Choose fire extinguishers by their size, class, and rating. For ordinary residential use, extinguishers two and a half to five pounds in largeness usually are adequate; these weigh five to ten pounds.

'Class' refers to the types of fires an extinguisher can put out. 'Size' refers to the weight of the fire-fighting chemical, or charge, a fire extinguisher contains, and usually is about half the weight of the fire extinguisher itself. Generally, their charge consists of carbonated water, which is inexpensive and adequate for the chore but quite dangerous if used against grease fires (the pressurized water can spread the burning grease) and electrical fires (the water stream and wetted surfaces can become electrified, delivering a perhaps fatal shock). Class A extinguishers are for use only on ordinary combustible materials such as wood, paper, and cloth. Usually their charge consists of powdered sodium bicarbonate (baking soda).

Class C extinguishers are for electrical fires. Class B extinguishers are for use on flammable liquids, including grease, oil, gasoline, and other chemicals. Some Class C extinguishers contain halon gas, but these are no longer manufactured for residential use of halon's adverse complete on the earth's ozone layer. Most contain dry ammonium phosphate. Another advantage of halon is that it expands into hard-to-reach areas and on every side obstructions, quenching fire in places other extinguishers cannot touch.

Many fire extinguishers contain chemicals for putting out union fires; in fact, extinguishers classed B:C and even ARC are more widely available for home use than extinguishers designed only for individual types of fires. Halon extinguishers are recommended for use about priceless electronic gear such as computers and televisions; the gas blankets the fire, suffocating it, and then evaporates without leaving chemical residue that can ruin the equipment. The higher the rating, the more effective the extinguisher is against the category of fire to which the rating is assigned. All-purpose ARC extinguishers usually are the best pick for any household location; however, B:C extinguishers put out grease fires more effectively (their charge of sodium bicarbonate reacts with fats and cooking oil to form a wet foam that smothers the fire) and so should be the first volition in a kitchen.

'Rating' is a survey of a fire extinguisher's effectiveness on a given type of fire. Class C extinguishers carry no ratings.

For protection on an entire floor of a house, buy a thereof great extinguisher; for example, a paragon rated 3A:40B:C. Actually, the rating system is a bit more complicated: rating numbers assigned to a Class A extinguisher denote the approximate gallons of water needed to match the extinguisher's capacity (for example, a 1A rating indicates that the extinguisher functions as well as about a gallon of water), during the time numbers assigned to Class B extinguishers betoken the approximate square footage of fire that can be extinguished by an pair off nonprofessional user. In a kitchen, choose a 5B:C unit; these weigh about three pounds and cost without $15. These weigh about ten pounds and cost all round $50. Kitchen fires usually start inconsiderable and are readily handled by a unimportant extinguisher; smaller extinguishers are more manageable than larger ones, especially in confined spaces; and, even a by snatches used extinguisher must be recharged to provide for it for further use or replaced, having multiple little extinguishers makes better economic sense.

A 5B:C extinguisher is also a advantage discretion for protecting a garage, where grease and oil fires are most likely. For on the rise kitchen protection, it is prima facie Latin better to buy two small in size extinguishers than a single larger model. These, too, weigh about three pounds (some weigh up to five pounds) and cost right and left $15. For workshops, service rooms, and similar locations, obtain IA: lOB:C extinguishers. Use mounting brackets producing for the purpose; these attach with plurality screws to wall studs and allow extinguishers to be instantly removed. In all cases, buy only extinguishers listed by Underwriters Laboratories.

Mount fire extinguishers in homespun sight on walls close at hand doorways or other potential retreat routes. Coast Guard. Instead of the plastic brackets that come with myriad fire extinguishers, consider the sturdier marine brackets respected by the U.S. Do not keep fire extinguishers in closets or elsewhere out of sight; in an emergency they are likely to be overlooked.

Buy fire extinguishers that have pressure gauges that enable you to check the clause of the charge at a glance. The correct mounting sublimity for extinguishers is amidst quadratic and five feet above the floor, but mount them as high as six feet if unavoidable to keep them out of the reach of in children. Fire extinguishers that cannot be recharged or have outlasted their rated life span, which is printed on the label, must be replaced. Inspect the gauge once a month; have an extinguisher recharged where you bought it or through your local fire department whenever the gauge indicates it has lost pressure or it has been used, even if only for a few seconds. Unfortunately, recharging a smaller extinguisher every hour costs nearly as much as replacing it and may not restore the extinguisher to its original condition. In no case should you keep a fire extinguisher longer than ten years, regardless of the manufacturer's claims. To do this, discharge the extinguisher (the load are nontoxic) into a paper or plastic bag, and then discard both the bag and the extinguisher in the trash. Wasteful as it seems, it is usually better to replace most residential fire extinguishers rather than have them recharged. A interest way to do this is to spread a bulky sheet of plastic on the ground and use it as a test area (the bale of most extinguishers will kill grass and stain pavement). Aluminum extinguisher cylinders can be recycled.

Everyone in the household except green children should practice using a fire extinguisher to learn the technique in case a fire breaks out. (If you cannot get within six feet of a fire of smoke or intense heat, do not try to quench it; evacuate the house and call the fire department.) Holding the extinguisher upright, pull the locking pin from the handle and aim the nozzle at the support of the flames. To operate a fire extinguisher properly, stand or kneel six to ten feet from the fire with your rear to the nearest exit. Watch for flames to rekindle, and be prepared to spray again.

Chimney Fire Extinguishers

If you operate a fireplace or wood-burning stove, keep on hand two or three oxygen-starving sticks, available at fireplace and woodstove dealers. Then squeeze the handle and snuff the fire by sweeping the nozzle from side to side to blanket the fire with retardant until the flames go out. Evacuate the house and call the fire department immediately in any case. In case of a chimney fire, tossing the sticks into the flames will quickly quench a fire inside the chimney flue or stovepipe.
