While a fire extinguisher is an essential home safety tool, that everyone should have in their home and know how to use there is one thing that many homeowners don’t know when it comes to their fire extinguisher, how to clean up the powder after using one. While a fire extinguisher is essential for stopping small fires from raging out of control, the residue that they leave behind requires thorough cleaning. Whether you’re dealing with a small household fire or a larger commercial incident, knowing how to clean up after a fire extinguisher is crucial. Our comprehensive guide will walk you through the steps of cleanup and include tips on how anyone can handle the task, from the fledgling to the most experienced DIYer.

Assessing the Situation

Before diving into cleanup efforts, it’s essential to assess the situation:

  • Safety First: Ensure the area is safe to enter and that there are no lingering fire hazards, smoke, or toxic fumes. If you’ve just put out a fire adrenaline can be running high, so make sure that you and your family are safe before worrying about cleanup. 
  • Extent of Powder Spread: Determine the extent of the fire extinguisher powder spread and identify any areas that require immediate attention. Kitchens are the most common spot for fires in a home, so it is often best to make sure that you aren’t contaminating any food or water sources. Also, if the fire extinguisher was used in a high-traffic area make sure to gameplan where you are going to begin. 
  • Potential Damage: Evaluate any potential damage to surfaces, materials, and electronics caused by the fire extinguisher powder. Fire extinguisher powder is hygroscopic which means that it can form a hard shell around the things it was sprayed onto. Furthermore, it can be corrosive to electronics, wiring, and appliances. Identifying these things can help you to avoid having problems in the long run.  

DIY Cleanup Techniques

For those who feel up to handling clean-up on their own here are the steps and techniques that should be used to effectively clean up fire extinguisher powder:

  • Protective Gear: With adrenaline coursing through your veins it is very easy to put out a fire and then feel the immediate need to go into cleanup mode. However, taking time to change into a different set of clothes and obtain personal protective equipment (PPE), such as gloves, a face mask, and safety goggles would be a great move. Fire extinguisher powder can irritate skin, noses, eyes, ears, throats, and lungs, so it is best to limit the opportunities for the powder to come into contact with you. 
  • Containment: Begin by containing the powder to prevent it from spreading further. The powder is incredibly fine and can be spread through a house extremely fast. If you can, use tarps or plastic sheeting to contain the powder in one area of your home. If you don’t have tarps or plastic sheeting, you can use a set of old sheets, curtains or even large pieces of cardboard. 
  • Vacuuming: Use a high-powered vacuum cleaner with a HEPA filter to carefully vacuum up the fire extinguisher powder. Older vacuums or shop vacuums can get the job done as well but have a higher chance of releasing microparticles of the powder back into the air. Be thorough in your vacuuming to ensure you remove as much powder as possible. A pro tip is to start at the outer edges and work your way towards the center. This creates a surefire way to make sure you are effectively containing the spread of the powder and ensures effective cleanup. 
  • Surface Cleaning: Wipe down surfaces with a damp cloth or sponge to remove any remaining powder residue. Make sure to rinse your rag or sponge frequently to make cleanup more efficient. If you are encountering stubborn powder stains or clumps a mild detergent or cleaning solution can be used to eliminate the problem. Make sure to avoid using harsh chemicals that will stain, corrode, or damage the surfaces you are cleaning. 
  • Air Circulation: The final step once cleanup is complete is to open windows, and use fans, or your home’s air circulation system to help dissipate any powder particles that are lingering in the air. This is the final step as doing this earlier in the cleaning process will only create more work and spread the powder through the house. This will also help to accelerate any drying your home needs and solve any humidity issues you could face after using the extinguisher. 
  • Final Inspection: Once the cleanup is complete, conduct a thorough inspection of the area to ensure that all traces of fire extinguisher powder have been removed. At this point it is easy to imagine that you could be tired, adrenaline could be wearing off, or that you simply want to be done cleaning. Make sure though to pay attention to any hard-to-reach areas, cracks, crevices, or spaces under or around appliances. Catching these hard-to-reach-areas on initial cleanup is much easier than finding and cleaning powder the next day, or days in the future. 

DIY cleanup is suitable for small, localized incidents and can save money in exchange for your time. However, for larger areas or extensive fires that have been put out, the best DIYer may not be as thorough or efficient as a professional restoration company.
