MS-FE-02 Small CO2 Fire Extinguisher

MS-FE-02 Small CO2 Fire Extinguisher Introduction

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.
CO2 cylinders are red and range in size from 5 lbs to 100 lbs or larger. In the larger sizes, the hard horn will be located on the end of a long, flexible hose.
 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.
 2. How to use:
 1. Pull the Pin at the top of the extinguisher. The pin releases a locking mechanism and   will allow  you to discharge the extinguisher.
 2. Aim at the base of the fire, not the flames. This is important - in order to put out the fire, you must extinguish the fuel.
 3. Squeeze the lever slowly. This will release the extinguishing agent in the extinguisher. If the handle is  seleased, the discharge will stop. 
 4. Sweep from side to side. Using a sweeping motion, move the fire extinguisher back and forth until the fire is completely out. Operate the extinguisher from a safe distance, several feet away, and then move  towards the fire once it starts to diminish. 
 5. Be sure to have read the instructions on your fire extinguisher.
