Dry Chemical Fire Extinguishers

Dry chemical fire extinguishers are the most widely used extinguisher type in Thailand. The familiar red cylinder contains monoammonium phosphate powder pressurized with nitrogen. ABC-rated powder covers three fire classes: Class A (wood, paper, fabric, plastics), Class B (fuel, thinner, grease), and Class C (energized electrical equipment), smothering the fuel surface to break the combustion reaction.

Sizes range from 5 lb through 10, 15, and 20 lb. The 5-10 lb units are right for homes, vehicles, and small shops, while 15-20 lb units suit office buildings, warehouses, construction sites, gas stations, and factories. Thai building regulations require at least one extinguisher per 1,000 square meters of floor area, spaced no more than 45 meters apart and mounted no higher than 1.50 meters from the floor.

ABC dry chemical extinguishers are the most economical option and the most versatile across fire types. Each unit has a pressure gauge for quick readiness checks. Invert the cylinder every 3-6 months to keep the powder from compacting, and replace the powder every 5 years.
