		Dry Chemical Fire Extinguisher Dry chemical fire extinguishers are usually rated for multi-use, and have more than one designator (A-B, B-C, or A-B-C, etc.). It is important to have the correct dry chemical fire extinguisher as each is filled with a different chemical. A general purpose fire extinguisher with a rating A-B-C is usually suitable for most homes, and many businesses, depending on the particular hazard. The advantage to dry chemical is that they leave a blanket of residue over the fire preventing reigniting.

		Carbon Dioxide Fire Extinguisher CO2 fire extinguishers are used for class B and C fires. They work by displacing the oxygen in a given area, suffocating and cooling the fire. These extinguishers should not be used on class A fires because they may reignite. They also should not be used on class D fires as reaction may occur. The advantage to using carbon dioxide is that is does not leave behind any harmful residues, making it suitable for fires involving delicate electronic equipment.

	WHAT TO DO AFTER USING AN EXTINGUISHER After an extinguisher has been used, even just a little bit, you must report it to our Office so that it can be recharged or replaced. While CO2 and Halon extinguishers will generally hold their pressure after a slight discharge, BC and ABC rated DRY CHEMICAL extinguishers will usually NOT hold a charge after partial use. While the gauge may hold steady in the green immediately after a light use, check it the next day and you'll find the gauge on EMPTY! This is because upon use the dry powder gets inside the seals and allows the nitrogen carrier gas to escape over a period of time. You can't "test" an extinguisher and put it back in the cabinet! Any discharge must be reported and the extinguisher recharged or replaced!!!
