Question

2.How many types of fire extinguisher used in school/home?​

Answer 1

There are several types of fire extinguishers commonly used in schools and homes. The specific types of fire extinguishers used vary depending on the location and nature of potential fire hazards. The most commonly encountered fire extinguishers include:

1. Water fire extinguishers (Class A): These are suitable for fires involving ordinary combustible materials, such as wood, paper, and fabric.

2. Foam fire extinguishers (Class A and B): These are effective against fires caused by flammable liquids, such as gasoline, oil, and paint.

3. Carbon dioxide (CO2) fire extinguishers (Class B and C): These are used for fires involving flammable liquids and electrical equipment, as CO2 does not leave a residue that can damage electrical components.

4. Dry powder fire extinguishers (Class A, B, C, and sometimes D): These extinguishers are versatile and can be used on fires involving flammable solids, flammable liquids, flammable gases, and electrical equipment.

5. Wet chemical fire extinguishers (Class A and K): These are designed for fires involving cooking oils and fats commonly found in kitchens.

It's imperative to note that fire extinguishers should be selected based on a proper assessment of fire risks and in compliance with local regulations and guidelines. Additionally, fire safety training and knowledge of how to use fire extinguishers correctly are crucial for effective fire response.

Answer 2

There are 5 primary types of fire extinguishers that are designed to put out different kinds of fires. Let's break them down:

1. Water, water mist, or water spray fire extinguishers: These types use water to extinguish fires. They are effective against fires caused by solid materials like paper, wood, and fabric.

2. Foam fire extinguishers: Foam extinguishers work by forming a film over the fire, preventing oxygen from reaching it. They are suitable for fires involving flammable liquids like gasoline or oil.

3. Dry Powder fire extinguishers: Dry powder extinguishers are versatile and can tackle various types of fires. They are effective against fires caused by flammable liquids, gases, and electrical equipment.

4. Carbon Dioxide (CO2) fire extinguishers: CO2 extinguishers work by displacing oxygen and suffocating the fire. They are ideal for electrical fires and fires involving flammable liquids.

5. Wet Chemical fire extinguishers: Wet chemical extinguishers are specifically designed for fires involving cooking oils and fats. They react with the oil to form a soapy film that seals the surface and extinguishes the fire.

For home use, the most common fire extinguisher type is the ABC fire extinguisher. It's a combination-type extinguisher that can handle fires of classes A, B, and C. This means it's suitable for fires involving common combustible materials, flammable liquids, and electrical equipment.

It's always important to have the right type of fire extinguisher available and to understand its proper use. Stay safe and be prepared!
