Saturday I was doing some work on an old corvette project. My corvette had been sitting in the garage for several months, and Saturday I started it up and pulled it out of the garage. I let it run for about 10 minutes and then pulled it back into the garage. While pulling into the garage I noticed smoke inside the car, and then I realized that there was a fire under my console. Fortunately I had a fire extinguisher mounted on the wall in the garage. I put the fire under the console out with the extinguisher. In addition, I realized that the fire was coming from under the car, and the heat and flames caused the fire in the console. This car was in my garage and was on fire. Without a fire extinguisher readily available in my garage, the situation could have gotten bad.
Fire extinguishers are divided into four categories, based on different types of fires. Each extinguisher has a numerical rating that serves as a guide for the type of fire. The types of fires include:
Class A - This extinguisher is for ordinary combustible materials such as paper, wood, etc. This extinguisher is a water type extinguisher, and this extinguisher should never be used for grease fires.
The other three extinguishers consist of some sort of dry chemical; also they could be filled with foam, powder, and are pressurized with nitrogen.
Class B - This extinguisher is for flammable or combustible liquids such as gas, grease, etc.
Class C - This extinguisher is for electrical equipment, such as wiring, circuit breakers, appliances, etc. The extinguisher has a non-conductive agent.
Class D - This extinguisher is for chemical fires such as metals, magnesium, etc.
The extinguisher I used was an ABC extinguisher, and this is a typical extinguisher you can buy at your local Wal-Mart, Kmart, etc.
