Red Fire Extinguishers: For The Common Combustibles

Red fire extinguishers are the all-rounder of fire safety tools. Packed with compressed water, they are designed to combat Class A fires involving ordinary combustible materials. When wood, paper, fabric, and plastic catch fire, these fire extinguishers can manage the resulting conflagration.

Cream Fire Extinguishers: Putting Out Flammable Liquids

Cream fire extinguishers, equipped to extinguish Class B fires, are your go-to option when flammable liquids catch fire. Filled with foam, these extinguishers are designed to create a blanket over the burning liquid, starving the fire of oxygen and cooling the flammable vapours. Whether it's petrol in a vehicle, oil in a heating system, solvents in a workshop, or paints in an art studio, cream extinguishers can keep these fires under control.

Blue Fire Extinguishers: Dealing With Gaseous Threats

Blue fire extinguishers, earmarked for Class C fires, come into play when dealing with flammable gases. They contain a dry powder that interrupts the chemical reaction within the fire, effectively smothering it. Fires caused by propane, methane, butane, and natural gas are managed effectively using these extinguishers.

Black Fire Extinguishers: The Metal Tamers

Fires involving flammable metals, known as Class D fires, may be rare but deadly. Black fire extinguishers, designed specifically for such instances, help manage fires involving metals like lithium, magnesium, potassium, and sodium. They contain a special powder that smothers the fire and forms a layer over the hot metal, preventing it from re-igniting.

Yellow Fire Extinguishers: Your Guard Against Electrical Fires

Electrical equipment can sometimes pose fire hazards. Yellow fire extinguishers, designed for Class E fires, are adept at combating fires caused by electrical equipment. Filled with carbon dioxide, a gas that displaces oxygen, these extinguishers remove the oxygen from the equation, without which the fire cannot burn. Furthermore, CO2 doesn't conduct electricity, making it safe to use around electrical appliances without the risk of electrocution.
