Here's our handy guide to clear out the residue and get your Whangarei business back to business:

Residue from Foam Type Fire Extinguishers

Foam fire extinguishers are used in offices and homes, but they are more powerful because they form a thick layer of foam on the fire that cuts off the oxygen supply.

Residue from Powder Fire Extinguishers (Dry Chemical)

Powder type fire extinguishers leave a lot of residue behind, necessitating thorough cleanup after each usage. Monoammonium phosphate, sodium bicarbonate, and potassium bicarbonate are among the firefighting ingredients found in dry chemical fire extinguishers.

Dry chemical fire extinguisher residue needs to be cleaned up right away because the powder they leave behind is very corrosive to metal surfaces.

Residue from Wet Chemical Fire Extinguishers

Wet chemical fire extinguishers are made of potassium and they are often used on kitchen fires. Potassium salts are sprayed out in a fine mist (carefully, so that the burning oil or fat doesn’t spread), and these salts react to make a soapy film on the surface of the burning substance. So when you clean up, you’ll have to deal with soapy residue, and you should clean up the mess before you start cooking again.

Safety First

Cleaning off residue is part of post-fire care. It offers your space a fresh start.

But no matter what kind of fire extinguisher you use, there are some general precautions you should take because some of them have the texture of fine baby powder and can irritate the skin particularly if you have allergies or skin asthma. Also some may contain chemicals that can trigger respiratory problems, so be on the safe side and put on some protective gear.
