AppId is over the quota
Fire extinguishers can save lives and every home and business should have one. Unfortunately, with the different classes and types how does anyone know which one is best? Does the kitchen require a different type than the garage? Is there a simple multipurpose option or will you need 5 or 6? Let's see if we can sort this out.
5 Different Classes To Consider
The class (rating) of a fire extinguisher tells what type of fire it should be used on. There are five different classes: class A, B, C, D, and K.
Class A is for ordinary combustibles like paper, wood, fiberglass, and cloth.
Class B is for burning liquids like gasoline, diesel fuel, cooking oil, kerosene, and propane.
Class C is for live electrical equipment fires like motors, appliances, wiring, fuse boxes, circuit breakers, machinery, and switches.
Class D is for combustible metals like magnesium, sodium, potassium, sodium-potassium alloy uranium, powdered aluminum, and lithium.
Class K is for cooking materials like grease, fats, and cooking oils. It is specifically designed for use in the kitchen and restaurants.
An easy way to remember what the letters mean is:
A for things that need Air to burn; B for things that come in Barrels; C for things with a Current; and K for common Kitchen fires.
