Carbon dioxide fire extinguishers are generally used because they absorb the oxygen content present in the air and thus help in extinguishing fire.
I need the answer please
Class A fire extinguishers - used for fires caused by "ordinary combustibles" aka paper, wood, plastic, cardboard, etc.Class B fire extinguishers - used for fires caused by flammable liquids such as gasoline and oil.Class C fire extinguishers - used for electrical firesClass D fire extinguishers - used for fires caused by explosive or flammable metals (most commonly found in laboratoriesClass K fire extinguishers - used for fires found in commercial kitchens
Class B: Class B extinguishers are used on fires involving flammable liquids, such as grease, gasoline, oil, and oil-based paints.
A self-contained fire extinguisher includes an extinguishing agent and usually a pressurized gas. In a CO2 extinguisher, the pressurized gas is also the agent.
Carbon monoxide is flammable so is not used in fire extinguishing systems. The carbon dioxide that is used in extinguishers can be deadly to humans as it displaces oxygen that a fire needs to burn, and humans need to breathe.
There are several types of fire extinguishers that one should purchase that rely on their compact form and low weight such as Alert 5 Rechargeable fire extinguishers, and Tundra Tundra extinguishers.
Water extinguishers are common and inexpensive to maintain. Dry chemical extinguishers are more versatile and thus quite common, although more expensive, and they are not susceptible to damage from freezing temperatures.
Fire extinguishers should be stored and mounted where they are readily accessible on a boat, where they will not be damaged and where they can be inspected regularly.
C02 is a clean and gaseous agent which displaces oxygen. These fire extinguishers are good for Class B flammable liquids and Class E electrically energised equipment fires.
Where they are readily available
