A Comprehensive Guide to Fire Extinguisher Types and Their Uses

When it comes to fire safety, having the right type of fire extinguisher can be the difference between a minor incident and a major disaster. Fire is one of the leading causes of loss in almost every industry, so it's important to not only have fire safety equipment on hand, but to understand how to use it. In this article, SkyGeek dives deep into fire safety, with a guide to fire extinguisher types and their uses. Read a brief description of the different types of fire extinguishers available, what types of fires they're used for, and their effectiveness in combatting various types of fires.

Class A Fire Extinguishers:

Class A fire extinguishers are designed to put out fires that involve ordinary combustibles such as wood, paper, cloth and plastics. Class A fire extinguishers are typically kept in residential spaces because they work on the most common type of fires that occur in homes and offices. Class A fire extinguishers work by cooling the fire and removing heat from the fuel source, thereby extinguishing the flames.

Class B Fire Extinguishers:

Class B fire extinguishers are used to put out fires that involve flammable liquids such as gasoline, oil or grease. These types of fires are common in garages and workshops where these liquids are frequently used. Automotive repair shops, aircraft hangars and similar businesses often have a Class B fire extinguisher available in the event of a fire emergency. Class B extinguishers work by smothering the fire and preventing oxygen from reaching the fuel source, thereby extinguishing the flames.

Class C Fire Extinguishers:

Class C fire extinguishers are used to put out fires that involve electrical equipment such as appliances, computers and wiring. These types of fires can be very dangerous as the electrical current can be conducted through the water or foam used in a standard fire extinguisher, putting the person attempting to extinguish the fire at risk of electrocution. Class C fire extinguishers are often kept in places like server rooms, where the risk of electrical fires is high. Class C extinguishers work by using non-conductive agents to extinguish the fire, such as carbon dioxide or dry chemical powder.

Class D Fire Extinguishers:

Class D fire extinguishers are used to put out fires that involve flammable metals such as magnesium, titanium and sodium. These types of fires are rare, but they can be extremely dangerous and require specialized extinguishers to combat them. Certain types of laboratories may need to have this type of fire extinguisher on hand. Class D extinguishers work similarly to other fire extinguishers, by smothering the fire and preventing oxygen from reaching the fuel source. However, they use an extinguishing agent that will not react with flammable metals.

Class K Fire Extinguishers:

Class K fire extinguishers are used to put out fires that involve cooking oils, grease and fats. These types of fires are common in commercial kitchens and can be extremely dangerous if not dealt with quickly and effectively. Water can cause a grease fire to spread quickly, so these types of fire emergencies require a fire extinguisher the does not use water as the extinguishing agent. Class K extinguishers work by using a wet chemical agent that reacts with the oil or fat to form a soap-like substance, thereby extinguishing the fire.

Conclusion:

Understanding the different types of fire extinguishers available, their uses, and their effectiveness in combatting various types of fires can mean the difference between a minor incident and a major disaster. Be sure to have the proper fire extinguishers on hand and make sure that they're readily available in the event of a fire emergency.
