Features of fire extinguishers
Not all fire extinguishers are the same. If you need to choose one of these devices, you have to know the various types so you can get the right one for your needs. Fire extinguishers that have an A classification are for ordinary combustibles, while B means they are for flammable liquids. C means that the device will work with electrical equipment, D means they are for metals, and K means they are for combustible cooking materials including oil and fat. They also have number ratings in addition to the letters.
For the A rated extinguisher, the number 1 means that it is the equivalent of 1.25 gallons of water. A 2 is for 2.5 gallons, and a 3 is for 3.75 gallons. For B and C devices, the numbers relate to the amount of square footage the fire extinguisher can cover. For example, a “5” means it can cover five square feet.
When you choose a fire extinguisher, you have to think carefully about the type of fires that are most likely to break out in a certain area. For example, those who are running a kitchen area would need to have an extinguisher that will work with cooking fires. Those who are working around flammable liquids need to have an extinguisher that will douse flammable liquids.
This might mean that you need to have several different extinguishers on your job site. Get the ones you need, and make sure that everyone on the crew understands how to use them and which fire extinguishers are for which types of fire.
