I grew up with a firefighter dad, and because of that, fire safety has been ingrained into me. I keep three fire extinguishers in my shop (see below). Not to mention, I also have two large buckets full of water at all times that I use for cooling steel. Anyone using a forge or working around power tools and other heat sources should have a fire extinguisher on hand.

When selecting a fire extinguisher it’s important to understand the different types. The most common types are classified as Class A, B, or C.

Keep Class A and Class B fire extinguishers nearby.

Class A fire extinguishers are effective against fires involving wood, paper, trash, textiles, or plastics. Class B fire extinguishers are effective against liquid fires involving gasoline, kerosene, oils, or even paints. Class C fire extinguishers are effective against electrical fires involving live electrical equipment. So just try to remember: Class A is for trash, Class B is for liquid, and Class C is for electrical.

I recommend keeping a Class A or a general-purpose extinguisher on hand in case of emergency. And if you’re quenching a hot blade into oil (a step that I cover later on), keep a Class B fire extinguisher nearby too. Never dump a bucket of water on an oil fire. Oil has a lower density than water, meaning it will always float on top. Adding water to an oil fire will only help the fire travel. A bucket of sand or fine dirt would do a better job than water.
