How to Clean Up Fire Extinguisher Chemicals

Cleaning up the leftover residue from using a fire extinguisher can be as easy as simply letting the chemicals evaporate, or it may involve some scrubbing to remove any remaining traces of the chemicals. It all depends on what type of fire extinguisher you have. Different types of fire extinguishers require different Below are the different types of fire extinguishers and directions as to how to clean up each one.

Things You'll Need

• Water
• Gloves
• Vacuum
• Broom and dustpan
• Soap
• Scrubbing brush

Instructions

1. Let it dry without doing anything at all. Some fire extinguishers simply contain carbon dioxide or halotron, which leaves no residue and is environmentally friendly. These are commonly used in places that are sensitive, such as in a computer lab. The downside is that they can be used only at close range.

2. Wash and evaporate. For fire extinguishers that use foam, which prevents flash fires and serves to tamp them down, you must let the foam evaporate, then mop it up. You can also rinse the foam to another location, then let it evaporate. The evaporating foam and leftover residue are not harmful. Foam fire extinguishers are usually used in workshops, garages and kitchens.

3. Sweep and scrub. Some fire extinguishers contain mono ammonium phosphate, which is a dry chemical that works well on all types of fires. This chemical can be corrosive. First, sweep and vacuum the affected area, removing as much of the chemical as possible. Then, scrub any areas that may be affected by corrosion, such as metals and floors. These fire extinguishers are used in areas where multiple types of fires can be a concern, such as hospitals, labs or public buildings.

4. Sweep and rinse. Another type of dry chemical fire extinguisher uses sodium bicarbonate. It is often used in homes. Because it is non-toxic, you can simply sweep, vacuum and wash it away without worry.

5. Mop it up. Some fire extinguishers simply contain pressurized water. These are often used in schools or other places where simple fires, fueled by paper or cloth, occur. To clean up, first throw ruined items away, then mop up any remaining water.
