Every house should have at least one fire extinguisher, situated in the kitchen. Better still is to put in fire extinguishers on each degree of a home and in each potentially hazardous area, including (apart from the kitchen) the garage, furnace room, and workshop.

Choose fire extinguishers by their dimension, class, and evaluation. "Size" refers to the weight of the fire-fighting compound, or charge, an fire extinguisher contains, and is about half of the weight of their fire extinguisher itself. For ordinary residential use, extinguishers two and a half to five pounds in size usually are adequate; these weigh five to eight lbs.

"Class" refers to the types of fires that an extinguisher can put out. Class A extinguishers are for use only on ordinary combustible materials like wood, paper, and cloth. Generally, their charge consists of carbonated water, which is inexpensive and adequate for the job but quite dangerous if used against dirt fires (the pressurized water can spread the burning grease) and electric fires (the water stream and wetted surfaces can become electrified, delivering a potentially fatal jolt ). Class B extinguishers are for use on flammable fluids, such as grease, oil, gasoline, and other chemicals. Normally their fee contains powdered sodium bicarbonate (baking soda).

Class C extinguishers are for electric fires. Most contain dry ammonium phosphate. Some Class C extinguishers contain halon gas, but these are not made for residential use due to halon's adverse influence on the planet's ozone layer. Halon extinguishers are recommended for use around expensive electronics such as computers and televisions; the gas blankets the flame, suffocating it, and then disappears without leaving chemical residue which can ruin the equipment. Another advantage of halon is it assembles to hard-to-reach areas and around obstructions, quenching fire in places other extinguishers can't touch.

Many fire extinguishers contain compounds for putting out mix fires; in actuality, extinguishers classed B:C as well as ARC are more broadly available for home use than extinguishers designed just for individual types of fires. All-purpose ARC extinguishers are the best choice for any household place nonetheless, B:C extinguishers put out grease fires more effectively (their charge of sodium bicarbonate reacts with fats and cooking oil to produce a moist foam that smothers the flame ) and so should be the first choice in a kitchen.

"Rating" is a dimension of a fire extinguisher's effectiveness on a particular type of fire. The higher the score, the more effective the extinguisher is against the class of passion to which the score is assigned. Actually, the rating system is somewhat more complicated: evaluation numbers assigned to a Class A extinguisher suggest that the approximate gallons of water required to rival the extinguisher's capacity (for example, a 1A score indicates that the extinguisher functions as well as approximately a gallon of water), whereas numbers assigned to Class B extinguishers indicate the approximate square footage of fire which can be extinguished by an average nonprofessional user. Class C extinguishers carry no ratings.




For protection on an entire floor of a house, purchase a comparatively large extinguisher; for instance, a model rated 3A:40B:C. These weigh about ten pounds and cost around $50. In a kitchen, select a 5B:C device; these weigh around three pounds and cost approximately $15. For greater kitchen protection, it's probably better to purchase two little extinguishers than a single larger model. Kitchen fires generally start small and may be managed by a small extinguisher; smaller extinguishers are more manageable than larger ones, especially in confined spaces; yet, because a partially used extinguisher must be recharged to prepare it for further use or replaced, having multiple tiny extinguishers makes better sense.

A 5B:C Amp is also a fantastic selection for protecting a garage, where dirt and oil fires are probably. For workshops, utility rooms, and related places, obtain IA: lOB:C extinguishers. These, also, weigh around three pounds (some weigh up to five pounds) and cost approximately $15. In all cases, purchase only extinguishers listed by Underwriters Laboratories.

Mount fire extinguishers in plain sight on walls near doorways or other potential escape routes. Use mounting brackets made for the purpose; these connect with extended screws to wall studs and allow extinguishers to be immediately eliminated. Instead of the plastic brackets that come with a lot of fire extinguishers, think about the sturdier sea mounts approved by the U.S. Coast Guard. The proper mounting height for extinguishers is between four and five feet above the ground, but bracket them as large as half an hour if needed to keep them out of the reach of young kids. Do not keep fire extinguishers in closets or elsewhere from sight; in an emergency they are likely to be missed.

Purchase fire extinguishers that have pressure gauges that enable you to check the state of the charge at a glance. Inspect the gauge once a month; possess an extinguisher recharged where you purchased it or through the regional fire department if the gauge indicates it has dropped pressure or after it has been used, even if just for a few seconds. Fire extinguishers that cannot be recharged or have outlasted their rated life span, which can be printed on the tag, must be substituted. In no case should you maintain a fire extinguisher longer than ten decades, whatever the maker's claims. Regrettably, recharging a smaller extinguisher often costs nearly as much as replacing it and may not restore the extinguisher to its initial state. Wasteful as it seems, it is normally better to replace most residential fire extinguishers rather than have them recharged. To try it, release the extinguisher (the contents are nontoxic) to a paper or plastic bag, and then discard both the bag and the extinguisher from the trash. Aluminum extinguisher cylinders can be recycled.

Everyone in the family except young kids should practice using a fire extinguisher to learn the technique if a fire breaks out. A good means to do this is to disperse a huge sheet of plastic on the floor and use it as an evaluation place (the contents of the majority of extinguishers will kill grass and blot pavement). To operate a fire extinguisher correctly, stand or kneel six to ten feet in the fire with your back to the nearest exit. (If you cannot get within six feet of a fire due to smoke or extreme heat, don't try to extinguish it; evacuate the house and call the fire department.) Holding the extinguisher upright, pull the locking pin from the grip and then aim the nozzle at the base of the flames. Then squeeze the grip and then extinguish the fire by sweeping the nozzle from side to side to blanket the fire with retardant until the flames go out. Watch for fires to rekindle, and be prepared to spray again.

Chimney Fire Extinguishers

If you run a fireplace or wood-burning stove, continue hand three or two oxygen-starving sticks, available at fireplace and woodstove dealers. In the event of a chimney fire, then tossing the sticks into the fires will immediately quench a fire inside the chimney flue or stovepipe. Evacuate the home and call the fire department immediately in any case. To know more information click fire extinguisher inspection and maintenance
