There’s been a lot of discussion concerning shop safety and how to protect ourselves. There really hasn’t been too much discussion about fire extinguishers. I can’t emphasize enough the value of having one close by. I’ve always kept one in or near the kitchen and garage area, and many in the shop. Knowing how to use one and which ones are for what type of fires is important. I’ve had a few fires and in a shop area, especially a wood shop, a fire can get rampant in a hurry. Here’s a short description of the types.
Fire Extinguisher Ratings
Class A Extinguishers will put out fires in ordinary combustibles, such as wood and paper. The numerical rating for this class of fire extinguisher refers to the amount of water the fire extinguisher holds and the amount of fire it will extinguish.
Class B Extinguishers should be used on fires involving flammable liquids, such as grease, gasoline, oil, etc. The numerical rating for this class of fire extinguisher states the approximate number of square feet of a flammable liquid fire that a non-expert person can expect to extinguish.
Class C Extinguishers are suitable for use on electrically energized fires. This class of fire extinguishers does not have a numerical rating. The presence of the letter “C” indicates that the extinguishing agent is non-conductive.
Class D Extinguishers are designed for use on flammable metals and are often specific for the type of metal in question. There is no picture designator for Class D extinguishers. These extinguishers generally have no rating nor are they given a multi-purpose rating for use on other types of fires.
