4KG DRY POWDER FIRE EXTINGUISHER

A 4kg dry powder fire extinguisher is a portable device used to suppress fires. Here are some key features and considerations related to this type of fire extinguisher:

1. Weight and Capacity: The "4kg" specification indicates that the fire extinguisher can hold 4 kilograms (or approximately 4 liters) of dry powder.
2. Extinguishing Agent: Dry powder fire extinguishers typically contain a fine powder composed of chemicals such as mono ammonium phosphate or ammonium sulfate. The powder works by interrupting the chemical reaction that sustains the fire, effectively suppressing the flames.
3. Fire Class: A 4kg dry powder fire extinguisher is suitable for use on fires classified as Class A, Class B, and Class C. This means it can be used on fires involving ordinary combustibles (Class A), flammable liquids and gases (Class B), and electrical fires (Class C).
4. Usage: When using a dry powder fire extinguisher, it's important to follow the P.A.S.S. technique:
   • P: Pull the pin or safety clip to unlock the extinguisher.
   • A: Aim the nozzle or hose at the base of the fire, standing a safe distance away.
   • S: Squeeze the handle to discharge the powder, sweeping it from side to side across the base of the fire.
   • S: Sweep the extinguisher back and forth until the fire is completely out, while maintaining a safe distance.
