What is the difference between dry powder and CO2 fire extinguisher?
Carbon dioxide can be used on Class B & C fires. They are usually ineffective on Class A fires. Dry Chemical fire extinguishers extinguish the fire primarily by interrupting the chemical reaction of the fire triangle.
What can CO2 fire extinguishers not be used on?
Dangers: CO2 extinguishers should not be used on fires involving solid materials, such as paper, wood and fabric, and also are not suitable for use on flammable gases.
Does CO2 fire extinguisher leave residue?
They do not leave any residue after the fire is extinguished. Carbon dioxide cuts off the oxygen supply and brings down the temperature of the fire with its cold presence. Once the CO2 gas has extinguished the fire, it will dissipate into the atmosphere without leaving a trace. No residue typically means no damage.
What are dry powder extinguishers used for?
Dry powder extinguishers smother fires by forming a barrier between the fuel and source of oxygen. The label colour for this type of extinguisher is yellow. Wet chemical extinguishers can also be used for fires caused by various organic materials including wood, coal, textiles, fabrics, cardboard and paper.
What advantage does CO2 have over a dry chemical extinguisher?

Is carbon dioxide a fire extinguisher?
Carbon dioxide extinguishes fire by displacing the air that supplies oxygen for combustion . Its normal uses are Class B (flammable liquids) and Class C (electrical ) fires. Carbon dioxide also is used to a lesser extent on Class A (textile, wood, and paper) fires.
What type of fire extinguisher is dry powder?
