Carbon Dioxide extinguishers are filled with non-flammable carbon dioxide gas under extreme pressure. You can recognize a
CO2 extinguisher by its hard horn and lack of pressure gauge. The pressure in the cylinder is so great that when you use one of
these extinguishers, bits of dry ice may shoot out the horn.
Extinguisher LabelCO2s are designed for Class B and C (flammable liquid and electrical) fires only.
Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. The carbon
dioxide is also very cold as it comes out of the extinguisher, so it cools the fuel as well. CO2s may be ineffective at extinguishing
Class A fires because they may not be able to displace enough oxygen to successfully put the fire out. Class A materials may also smolder and re-ignite.
CO2s will frequently be found in laboratories, mechanical rooms, kitchens, and flammable liquid storage areas.
All CO2 extinguishers at USC undergo hydrostatic testing and recharge every five years.

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!!!
