How are fires and fire extinguishers grouped?

Fires and fire extinguishers are categorized based on the type of materials involved and their conditions, which helps in understanding the appropriate methods for extinguishing them. Fires are classified into classes based on the fuel involved:

• Class A fires involve ordinary combustibles such as wood, paper, and cloth.

• Class B fires involve flammable liquids and gases.

• Class C fires are associated with electrical equipment.

• Class D fires are related to combustible metals.

• Class K fires involve cooking oils and fats.

Fire extinguishers are also categorized into classes that correspond to the types of fires they are designed to combat. For instance, a Class A extinguisher is suitable for Class A fires, while a Class B extinguisher is appropriate for Class B fires.

Since both fires and extinguishers rely on this classification system, understanding that fires are grouped into classes while extinguishers are likewise categorized into classes is crucial for effective fire safety and management. This systematic approach ensures that firefighters and individuals can select the correct extinguisher for a specific type of fire, thereby enhancing safety and effectiveness during fire incidents.
