Knowing the different types of fire extinguishers and what they do will help in the process of cleaning fire extinguisher residue.

Following a fire to your home or business, fire extinguisher residue needs to be cleaned as soon as possible. Some types, depending on the extinguisher, can damage metal surfaces and electronics if left untreated. While SERVPRO® of Central Oklahoma City is always available to provide emergency fire damage clean up services, you may wish to begin the clean up process yourself. Here are some tips and important information regarding fire extinguisher residue and how to clean it up:

What Is Fire Extinguisher Residue?

According to CHEMGUARD, fire extinguisher foam is made of water, foam concentrate, and air. It is considered to be a stable group of tiny air filled bubbles with a lower density than water, oil, and gas. When the ingredients are mixed, they create the homogenous foam we see, that blankets spaces when aerated and discharged.

For cleanup for dry chemical extinguishers that put out class A, B, and/or C fires:

• Vacuum or sweep up as much of the residue as possible.
• Mix a solution of 50% warm water and 50% isopropyl alcohol, then spray the mixture to break up any leftover silicone. Allow the solution to settle for about five minutes, then rinse with warm water.
• Treating sodium bicarbonate and potassium bicarbonate based dry chemicals is handled slightly differently. First, mix 2% vinegar and 98% hot water, then wash the affected area. Allow the solution to sit for about five minutes, then rinse with warm water.
• Treating monoammonium phosphate- first, mix baking soda and hot water. Allow the solution to settle for approximately five minutes, then rinse with warm water.
• Using soap and water, wash and rinse the affected area(s).
• Lastly, use a fan to spot dry any remaining wet areas.

For wet chemical extinguishers that put out class K fires:

• Turn off all fuel sources that may be connected to cooking equipment.
• Using hot water and soap, scrub the residue away with a sponge or cloth.
• Rinse affected areas and surfaces.
• Lastly, let the area dry completely before turning equipment back on.

For dry extinguishers that put out class D fires:

• Use a vacuum or brush to clean up the residue.
• Sweep all the collected residue into a trash bag or other method of containment, then properly dispose of it in a trash can.
• Lastly, use a damp cloth to wipe off any lingering powder from affected surfaces.
