Dry Powder Fire Extinguisher

• Extinguishing Agent: Dry powder fire extinguishers typically use a fine powder composed of chemicals such as monoammonium phosphate, ammonium sulfate, or sodium bicarbonate. The powder works by interrupting the chemical reaction that sustains the fire, suppressing the flames.
• Fire Class: Dry powder fire extinguishers are versatile and can be used on different fire classes. They are suitable for Class A fires (ordinary combustibles like wood, paper, cloth), Class B fires (flammable liquids and gases), and Class C fires (electrical fires). Some dry powder fire extinguishers may also have limited effectiveness on Class D fires (involving flammable metals).
• Usage: When using a dry powder fire extinguisher, follow these steps:
  • Pull the safety pin to unlock the extinguisher.
  • Aim the nozzle or hose at the base of the fire, standing a safe distance away.
  • Squeeze the handle to discharge the dry powder onto the fire.
  • Sweep the extinguisher from side to side, covering the area of the fire until it is fully suppressed.
