Fire Extinguisher Types Explained: Selecting the Best Option for Your Needs

Fire Extinguisher Types Explained: Selecting the Best Option for Your Needs: Given the fire extinguishers at work, their hearts are located behind the glass that is probably in danger in the classic fire extinguisher attached to the wall. However, according to the National Fire Prevention Association (NFPA), there are five fire classes, and according to the diverse nature of these fires, they enter. Each is designed to handle different types of fire situations and provide different levels of fire protection. It is therefore essential to have each type of fire extinguisher on hand.

When fire classes are considered, they are determined by the fire hazard that caused the fire and the materials fueling it. 

These are the parameters suggested by National Fire Prevention Association (NFPA).

• Class A fires are caused by flammable materials such as wood, paper, fabric, plastic, and rubber.

• Class B fires involve more highly flammable and combustible liquids. This may include oils, oil-based paints, varnishes, alcohols, petroleum lubricants, and gases.

• Class C fires are started by electrical equipment.

• Class D fires are caused by combustible metals. These may include lithium, potassium, sodium, zirconium, titanium, and magnesium.

• Class K fires are kitchen fires caused by flammable materials such as oil and grease in kitchen equipment.

Depending on the type of fire, take immediate action if the fire alarm sounds. Here we will introduce six types of fire extinguishers and when to use them for each type of fire.

1. ABC Dry Powder Fire Extinguisher

This is the type of fire extinguisher that most people think of. It is a red canister that can be used to fire a dry powder fire extinguisher onto a fire. This is a multi-purpose fire extinguisher that extinguishes fires using a powder fire extinguisher. These are typically used to fight Class A, B, and C fires.

 

2. Water Fire Extinguisher

We all know that water prevents fires, so it's no surprise that water mist extinguishers are effective against a variety of fires, including Class A and Class B fires. Unlike older water extinguishers, newer models use a mist of water that is dispersed over a large area. This fine mist suffocates and cools the fire, reducing the amount of oxygen and heat in the room. The cooling effect of water acts as a double attack against fire. Old water fire extinguishers are still in use, but they can cause damage to your home.

 

3. Fire Extinguisher

The foam of the fire extinguisher operates in the same way as other fire extinguishers, where the fuel fire is squeezed and killed. Foam extinguishers are effective against flammable liquid fires, such as Class B fires, as well as Class A fires involving paper, wood, and other flammable materials.

 

4. Wet Chemical Fire Extinguisher

Wet chemical extinguishers are effective against class A and K fires because of both its wet and cooling properties. The extinguishing agents are distributed in a fine spray texture, which limits fires without giving them fuel to spread.

 

5. Powder Fire Extinguisher

Dry powder fire extinguishers use dry chemicals, such as sodium bicarbonate base or potassium bicarbonate base, to cool and spread fires. Some dry powder fire extinguishers are labeled "BC" while others are labeled "ABC." What exactly do these labels mean? The "BC" and "ABC" markings indicate the types of fires that the extinguisher can extinguish. Dry chemical extinguishers labeled "BC" are designed to extinguish Class B and Class C fires. Dry chemical extinguishers marked "ABC" are designed to extinguish Class A fires, Class B and Class C fires.

 

6. CO2 Fire Extinguisher

Fire supplies oxygen, and carbon dioxide (CO2) quenches the oxygen. This means that the CO2 extinguisher sucks oxygen from the fire and extinguishes the fire's momentum. Effective against Class B fires as well as Class C electrical fires.

 


What is the Most Important Thing When Choosing a Fire Extinguisher?

The best fire extinguisher to use will depend on the type of fire, but the most important factors in choosing the right extinguisher are whether the people at the scene know how to use it and whether it is easily accessible. It's about whether it's in a place where you can do it. Without these two important elements, your fire extinguisher will not work. Train your employees and make sure they know where each fire extinguisher is located.
