1What we will learn today We will talk about different types of fire extinguishers, how to use them safely, and in what situations you would use them.
2We have already learned that: Fire needs heat, fuel and oxygen to create the chemical chain reaction that causes fireIf you remove one of the elements, the fire cannot survive
3Do you have a fire extinguisher in your home? Every home should have oneWhere is it located?Extinguishers should be located in plain view, near an escape routeKitchen, garage, workroom
4Fire extinguishers have chemicals in them that suppress the fire There are four different classes of firesClass of fire determines which extinguisher to useMost common type of extinguisher - use on most household fires - contains a combination of dry chemicals that look like a white powderpowder interrupts the chemical chain reaction and suffocates the fire
5Just like matches and lighters are not toys, a fire extinguisher is not a toy Cause damage if not used properlyShould only be used in emergency situations for one purpose - to extinguish a fire
6Fire extinguishers are identified by a letter that determines what materials it will be most effective on and a number that determines how much area it covers.4-A 20B:CThose two factors determine where and how long a fire extinguisher is most effective
7Letter designation tells us what the extinguisher is most effective on Ordinary combustibles such as wood, paper, clothing, household furnishingsBFlammable liquids such as gasoline, alcohol, paints, motor oil, cooking oil and cleanersCEnergized (plugged in) electrical equipment like televisions, computers or wiring
8The numbers tell us how large an area the extinguisher is most effective on. A number 1 would be on a small area extinguisher, like what you would find in a kitchen.Means there is only contents to be used on a very small, ordinary fire like wood or paperA number 4 rating means that it can extinguish a fire 4 times larger than a number 1 rating
9So the rating on our 4-A 20 B:C extinguisher means: Multipurpose extinguisher because of its A-B-C ratingCan extinguish a Class A fire times larger than a 1-ACan extinguish a Class B:C fire 20 times larger than a B:C4-A 20B:C
10Fire extinguishers should only be used in certain situations: the fire is smaller than a waste basketthe fire is contained to one item (like a small waste basket) and has not spread anywhere elseeveryone else is out of the buildingyou have a clear exit to safetyAnd only if you have been taught how to use it
11It is important to know when to use a fire extinguisher - and when not to. Unless the fire is very small and contained, do not try to fight a fire yourselfGet out, make sure everyone else is out, and call the fire department
12When using a fire extinguisher, remember to PASS Pull the pinAim the nozzleSqueeze the handleSweep the nozzleAlways aim at the base of the fire for the most effective use
13Like your smoke alarms, fire extinguishers need to be checked often to make sure it is in good working orderAfter use, it should be maintained or replaced
14REMEMBER - a fire extinguisher is an important fire safety tool REMEMBER - a fire extinguisher is an important fire safety tool. It should never be played with or pointed at someone.
