Fraud Blocker

If you recently had to put out a small fire in your home or workplace you may be wondering how to clean up the mess left over from the fire extinguisher. This is important to address quickly since the residue can be corrosive and potentially harmful if not cleaned properly.

What Type of Fire Extinguisher Was Used

First, determine which type of fire extinguisher was used, as this affects the cleanup method. The most common types are:

ABC powder (dry chemical) – A yellow-white powder
Carbon dioxide (CO2) – Leaves minimal residue
Class K (kitchen) – A foamy substance
Class D (metal fires) – A yellow powder

ABC Powder Fire Extinguisher Cleanup

For the most common type, ABC powder, here’s a thorough cleanup process:

Start by ventilating the area well by opening windows and doors. The fine particles can be irritating to breathe. If you’re cleaning indoors, consider wearing a dust mask and gloves to protect yourself.

Begin with a thorough vacuum using a vacuum cleaner with a HEPA filter. The powder is very fine, so a regular vacuum might just redistribute it into the air. Work methodically from the outer edges of the affected area toward the center to prevent spreading the residue further.

For surfaces like floors, walls, and furniture, create a cleaning solution using warm water and either white vinegar or a gentle alkaline cleaner (like baking soda mixed with water). The slightly acidic nature of vinegar helps neutralize the alkaline fire extinguisher powder. Apply the solution with a soft cloth or sponge, working in small sections and rinsing frequently with clean water to prevent smearing.

For delicate materials like upholstery or carpets, first test your cleaning solution on a small, hidden area. Use a gentle blotting motion rather than rubbing, which could drive the powder deeper into the fibers. You might need several passes, allowing the material to dry between cleanings.

For electronic equipment, avoid using water-based solutions. Instead, use compressed air to blow out the powder, followed by careful cleaning with electronics-safe contact cleaner. If valuable electronics were exposed to the powder, consider having them professionally cleaned to prevent corrosion.

After the initial cleanup, inspect surfaces in bright light – the powder often appears more visible from certain angles. You might need to repeat the process in areas where residue remains.

Finally, wipe down all cleaned surfaces with a damp microfiber cloth to remove any remaining cleaning solution. This helps prevent any residual chemical interaction between the cleaner and extinguisher powder.

Other Types of Fire Extinguishers: Class K or D

If you’re dealing with residue from a Class K or D extinguisher, or if valuable items were affected, consider consulting a professional cleaning service, as these require specialized cleaning methods to prevent damage.

Stay Prepared and Vigilant
