How To Clean Up Fire Extinguisher Residue

The use of a fire extinguisher is an invaluable tool to help save lives and property. But after using one, it’s important to clean up the residue. The recommended cleaning methods vary depending on the type of extinguisher you used. This guide will show you how to do it safely.

Dry Chemical Extinguisher

Dry chemical fire extinguishers work by spraying a powder-like substance on the fire that smothers it and prevents it from receiving oxygen. These fire fighting agents leave behind a corrosive powder that can damage metal surfaces if left in contact with the fire for a long period of time. If you’re cleaning up the residue of a dry chemical fire extinguisher, make sure you wear a dust mask, goggles and gloves as you vacuum. A dry vacuum cleaner is a good way to remove any residue that’s left behind from a dry chemical fire extinguisher without inhaling the dust.

Wet Chemical Extinguisher

If your extinguisher uses a wet chemical extinguisher, you can quickly clean up the residue it leaves behind. This type of extinguisher does not leave any powdery residue behind, but it’s important to clean up its discharge quickly to avoid irritation to skin and eyes or lungs. To clean up any dry chemical extinguisher residue, vacuum or sweep the area and then spray it with a solution of 50 percent isopropyl alcohol and warm water to get rid of any stuck-on particles. It’s also very easy to clean up if the extinguisher is in good condition and you have an industrial HEPA filter vacuum cleaner. And if neither of those solutions are convenient for you, you can always try cleaning it with a dry brush or soft sponge. But if there’s a lot of powder, you’ll have to use a wet brush or a combination of detergent and water to get rid of the residue completely.

Dry Powder Extinguisher

If you are using a dry powder extinguisher, you must take extra care when cleaning it. This is because the powder is corrosive and can irritate the eyes and lungs. Before you begin, ensure that you are wearing a dust mask and gloves. This will prevent the powder from getting into your lungs and eyes. When you are ready to clean your extinguisher, follow these steps: Spray the stuck-on residue with isopropyl alcohol diluted 50 percent in water. Then Let the solution sit for several minutes before wiping away with a damp cloth.
