Fire extinguishers are a handy and effective way of dealing with small fires in your home or business. All you have to do is just spray away in the direction of the flames and you’ve changed a potentially disastrous situation into a manageable one.
While that’s great, of course, all that spraying can leave quite a mess! Before you go back to business as usual, you’re going to want to clean up all that residue. And depending on the type of fire extinguisher, some cleaning methods are certainly better than others.
Before you start cleaning up, make sure you know what chemicals are in your fire extinguisher. Check the tag or label for information about the type and class of the agent inside.
If you find that you have a pressurized water or CO2 extinguisher, then you don’t need to worry about cleaning up any chemical residue. Just thoroughly dry the area and it should be fine.
For foam fire extinguishers, first dilute the residue before allowing it to dry. Afterward, you may also consider sanitizing or spot cleaning if there’s any remaining residue.
These are the most common fire extinguishers out there because they can put out class A, B, and C fires. Dry chemical extinguishers typically contain agents such as monoammonium phosphate, potassium bicarbonate, and sodium bicarbonate, which will leave you with a corrosive powder.
These are typically found in commercial kitchens and restaurants, as they are used to put out grease fires.
You’ll often find these in warehouses and factories as they can be used to put out fires involving titanium, magnesium, and other combustible metals.
