Fire extinguishers are something that no home should be without. Small fires could turn into big fires quickly.
There are many different types of extinguishers, but the ABC extinguishers are by far the most versatile for household use.
ABC – This is the multipurpose dry chemical extinguisher. The ABC type is filled with monoammonium phosphate, a yellow powder. The chemical is non-conductive and can be mildly corrosive if moisture is present. In order to avoid corrosion, it is necessary to scrub and thoroughly cleanup the contacted area once the fire is out.
An ABC extinguisher will work on the three most common types of fires.
When you purchase an extinguisher check to be sure that it is UL-listed (Underwriters Laboratory). The extinguisher will also be marked with a rating for example a standard 5lb extinguisher will normally be rated 3-A-40-BC. This tells you how much fire the extinguisher should handle. If these are not shown on the label do not purchase the fire extinguisher, it is probably cheaply made overseas and may not be reliable.
Where to place an extinguisher and how to use it.
Always place your extinguisher near an exit. If it fails to function or is insufficient to extinguish the fire you want an escape route. Be familiar with your extinguisher prior to ever having to use it. Know how to pull the pin to activate the extinguisher.
If you need to extinguish a fire, point the extinguisher at the base of the flames, squeeze the lever sweeping the extinguisher from side to side. If the fire is not put out, get out don’t be a dead hero. If the fire is out, check carefully for hot embers. If you can, wet everything down.
By law in most if not all states an extinguisher in a commercial establishment needs to be serviced annually. The reason an extinguisher needs to be serviced is because the powder compacts and settles to the bottom. If this happens you will not get a proper flow of powder.
Fire extinguishers have become so inexpensive, that instead of servicing them every couple of years you could buy a new one.
