Fire Safety Types and Extinguishers

Study Notes

Types of Fires

Class A Fire: Involves ordinary combustible materials such as wood, paper, and clothing.
Class B Fire: Combustion of flammable liquids and vapors, including paint, oil, grease, and gasoline.
Class C Fire: Fire involving electrical equipment, requiring specialized extinguishing methods.
Class D Fire: Involves combustible or reactive metals like sodium, potassium, magnesium, and lithium.
Class K Fire: Associated with high-temperature cooking oils, grease, or fats, commonly found in kitchens.

Fire Extinguishing Methods

Class A Extinguishing: Requires water or water-based solutions to effectively cool or quench the fire.
Class B Extinguishing: Involves blocking the source of oxygen or smothering fuels, utilizing foam, dry chemical, or carbon dioxide.
Class C Extinguishing: Necessitates non-conducting agents to avoid electrical hazards when extinguishing fires involving electrical equipment.
Class D Extinguishing: Requires dry powder agents or sand to handle fires involving reactive metals.
Class K Extinguishing: Utilizes agents that prevent splashing and cool while smothering the fire, specifically designed for kitchen fires.

Extinguishers Overview

Class A Extinguishers: Utilize soda and acid or water to effectively cool down fires involving ordinary combustibles.
Class B Extinguishers: Use foam, dry chemical, or carbon dioxide to extinguish fires from flammable liquids.
Class C Extinguishers: Include dry chemical (ABC), carbon dioxide (BC), halon, or other non-conducting agents.
Class ABC Extinguishers: Multipurpose units that use dry chemical reagents effective against Class A, B, and C fires.
Class K Extinguishers: Use potassium-based alkaline liquid specifically designed for high-temperature grease fires while also applicable for Class A, B, and C fires.
