Understanding the Different Classes of Fires and How to Extinguish Them

Fire safety is a critical aspect of workplace and residential safety. Understanding the different classes of fires and knowing how to extinguish them effectively can help prevent property damage, injuries, and loss of life. Additionally, having appropriate safety measures such as fire doors Melbourne, fire extinguisher training Melbourne, and evacuation diagrams Victoria ensures that businesses and individuals are prepared for emergencies.

Fire Classifications

Fires are categorized into different classes based on their fuel source. Each class requires a specific extinguishing method to prevent escalation and ensure safety.

Class A: Ordinary Combustibles

Class A fires involve common combustible materials such as wood, paper, fabric, and plastics. These fires are commonly found in homes, offices, and warehouses.

How to Extinguish:

• Use water or foam extinguishers to cool the flames and prevent re-ignition.

• Avoid using CO2 or dry chemical extinguishers, as they may not be effective in fully suppressing the fire.

Class B: Flammable Liquids and Gases

Class B fires involve flammable liquids like gasoline, oil, grease, and alcohol, as well as gases like propane and butane. These fires are often seen in industrial settings and kitchens.

How to Extinguish:

• Use foam, dry chemical, or CO2 extinguishers to smother the fire and cut off its oxygen supply.

• Never use water, as it can spread the flammable liquid and make the fire worse.

Class C: Electrical Fires

Class C fires are caused by electrical faults such as short circuits, faulty wiring, or overheating appliances. These fires pose significant risks in workplaces and homes.

How to Extinguish:

• Use CO2 or dry chemical extinguishers, which do not conduct electricity.

• Do not use water or foam extinguishers, as they can increase the risk of electrocution.

• Disconnect the power source if it is safe to do so.

Class D: Metal Fires

Class D fires involve combustible metals such as magnesium, titanium, and aluminum. These fires occur in laboratories and industrial facilities where metals are processed.

How to Extinguish:

• Use specialized Class D fire extinguishers containing dry powder to smother the fire.

• Water, foam, and CO2 should never be used, as they can cause violent reactions.

Class F: Cooking Oil and Grease Fires

Class F fires, also known as kitchen fires, involve cooking oils and fats commonly found in commercial and residential kitchens.

How to Extinguish:

• Use wet chemical extinguishers, which cool the flames and form a soapy barrier to prevent re-ignition.

• Never use water, as it can cause the burning oil to splatter and spread the fire.
