The 5 Types And Colours Of Fire Extinguishers And Their Uses

• Fire extinguishers are available in different types, including water, foam, dry powder, carbon dioxide (CO₂), and wet chemicals, each designed for specific fire hazards.

• Red, cream, blue, black, and yellow colour codes correspond to water, foam, dry powder, carbon dioxide, and wet chemical extinguishers, respectively.

• Fire extinguisher labels display classification letters, rating numbers, pictograms, certification marks, manufacturer details, and size information to ensure safe and correct use.

• TATA AIG offers fire insurance plans that offer comprehensive business protection with digital access, affordable premiums, and dedicated customer support.

Fire extinguishers are classified into different types based on their formulation. Here are the different classes of fire extinguishers.

• Water Fire Extinguisher

This is the most commonly used fire extinguisher for Class A fire involving combustible materials such as wood, paper, cloth, and plastics. They work by cooling the burning material and reducing the temperature below its ignition point.

• Dry Powder Fire Extinguisher

This type of fire extinguisher is versatile and can be used on Class A, B, and C fires, including fires caused by flammable gases. The powder interrupts the chemical reaction of the fire, quickly extinguishing the flames. They are commonly used in industrial settings and areas with multiple fire risks.

• Foam Fire Extinguisher

Foam fire extinguishers are effective for both Class A and Class B fires. They create a thick layer of foam that cuts off the oxygen supply while cooling the flames, making them ideal for fires involving flammable liquids such as petrol, diesel, and paint.

• Carbon Dioxide Fire Extinguisher

This fire extinguisher is used for Class B fires and electrical fires. They discharge CO₂ gas, which displaces oxygen around the fire and suppresses the flames without leaving any residue. This makes them suitable for offices, server rooms, and locations with sensitive electronic equipment.

• Wet Chemical Fire Extinguisher

Wet chemical fire extinguishers are specially designed for Class F fires involving cooking oils and fats. They release a fine mist and a chemical solution that cools the fire and forms a protective layer over the burning oil, preventing reignition. They are widely used in commercial kitchens, restaurants, and food preparation areas.

Each fire extinguisher comes with a colour code and label. Here is a general overview of different fire extinguisher types and colours and their agent types.

Reading a fire extinguisher label is essential to ensure it is suitable for the type of fire you need to tackle. The label provides important information about the extinguisher's contents, usage instructions, and safety precautions.

Identify Classification Letters

One of the most important details on a fire extinguisher label is the fire extinguisher class category, such as Class A, B, C, D, E and F. These classifications indicate the types of fire hazards the extinguisher is designed to handle. They are usually displayed prominently with letters and corresponding symbols.

Understand Rating Numbers

The fire extinguisher labels also include rating numbers, such as 2A:10B, which indicate the extinguisher's firefighting capacity. A higher rating generally means the extinguisher can handle a larger fire or provide greater extinguishing effectiveness.

Learn About Pictograms

Most fire extinguishers feature pictograms that visually represent the types of fires they can and cannot be used on. These symbols make it easy to identify the appropriate extinguisher even when reading text may not be practical. They also highlight restricted uses to prevent accidental misuse.

Pay Attention to Underwriters Laboratories Mark

The Underwriters Laboratories Mark is a certification that indicates fire extinguishers have been tested and meet established performance standards. Checking for this certification helps ensure the extinguisher is reliable and suitable for use in an emergency.

Know Manufacturer Information and Date Codes

The fire extinguisher label also contains information such as the manufacturer's name, model name, date of manufacture and more. Reviewing these details helps verify the extinguisher's authenticity, determine its age, and ensure it is serviced according to the recommended schedule.

Understand Size and Weight Considerations

The label specifies the extinguisher's size, weight, and the amount of extinguishing agent it contains. Choosing the appropriate size is important: larger extinguishers offer greater firefighting capacity. Still, they may be heavier to operate, while smaller units are easier to handle and are suitable for homes or small offices.

Knowing how to use a fire extinguisher based on the colour type is crucial for individuals and businesses. This will help in understanding which type of fire extinguisher is suitable for them. Along with this, proper safety measures and an emergency plan are also necessary to handle fire-related hazards.

Another crucial aspect of fire safety is having a fire insurance online policy that provides financial protection against unexpected fire-related losses. While fire extinguishers help control or minimise damage during an emergency, fire policy helps cover the cost of repairing or rebuilding the insured property and replacing damaged assets.

We also offer office insurance plans that protect from unexpected risks that can disrupt office operations.
