Fire Extinguisher Charge

Fire extinguisher charges are substances or agents that are used to extinguish fires. They are typically stored inside fire extinguishers and are released when the extinguisher is activated. The specific type of charge used depends on the type of fire the extinguisher is designed to combat. Here are some common types of fire extinguisher charges:

1. Water: Water is a common fire extinguisher charge used for Class A fires, which involve ordinary combustible materials such as wood, paper, and cloth.

2. Foam: Foam charges are used for Class A and Class B fires. They create a blanket of foam that helps to smother the fire and prevent re-ignition.

3. Carbon Dioxide (CO2): CO2 charges are used for Class B and Class C fires. Carbon dioxide displaces oxygen, effectively suffocating the fire.

4. Dry Chemical: Dry chemical charges are versatile and can be used for Class A, Class B, and Class C fires. They work by interrupting the chemical reaction of the fire.

5. Halon: Halon charges are effective for Class B and Class C fires. However, they are no longer widely used due to their negative impact on the environment.

6. Clean Agent: Clean agent charges, such as FM-200 or Novec 1230, are used for Class A, Class B, and Class C fires. They are non-toxic and leave no residue, making them suitable for use in sensitive areas.

It is important to note that the specific charges used may vary depending on the regulations and standards of different countries or regions. It is recommended to consult local fire safety authorities or professionals for the most accurate and up-to-date information on fire extinguisher charges.
