The ABC Powder Portable Fire Extinguisher (AS-1) is a compact and highly efficient fire safety device designed for quick response to small fire incidents in residential, commercial, and industrial environments. It is filled with multipurpose dry chemical powder (commonly mono ammonium phosphate) that is effective on Class A (solid materials), Class B (flammable liquids), and Class C (gases and electrical equipment) fires, making it a versatile solution for various fire hazards. The extinguisher operates on a stored pressure mechanism, allowing instant discharge when activated, and works by smothering flames, interrupting the chemical reaction of fire, and cutting off oxygen supply.
Typically available in a 1 kg capacity (AS-1 type), it is lightweight, easy to handle, and suitable for use in cars, offices, kitchens, shops, and small installations. It is manufactured with a corrosion-resistant mild steel or aluminum body, equipped with a pressure gauge, safety pin, discharge nozzle, and wall mounting bracket for convenient storage. These extinguishers are usually ISI-marked as per IS:15683 standards and operate effectively within a temperature range of approximately -0°C to +55°C.
