Why Choose the 4KG AB Dry Powder Fire Extinguisher?

Heavy-Duty Commercial Knockdown Power
The 4KG Dry Powder extinguisher is designed for environments requiring substantial fire-suppression capability and extended discharge duration. Equipped with a flexible discharge hose for precise aim and rapid coverage, it provides enhanced protection for high-traffic commercial spaces, storage facilities, industrial workshops, and large residential estates.

How It Protects You
Liquid and solid combustible fires escalate rapidly. This extinguisher discharges a specialized, siliconized monoammonium phosphate dry chemical that blankets active flames. Upon contact with high heat, the powder melts into a solid thermal barrier that starves the flame of ambient oxygen, cooling the combustion zone and preventing re-ignition.

✅ Effective against Class A & B fires (Including Electrical & Gas Origins)

Class A Fires: Organic solid combustibles such as wood, paper, cardboard, and textiles.

Class B Fires: Flammable liquids such as petrol, oil, thinners, and paints.

Electrical & Gas Origin Hazards: Under Singapore Standard SS 578:2019, portable extinguishers no longer carry standalone icons for electrical or gas fires. Always isolate the energy source (shut off the electrical main or gas supply) before suppression. Once isolated, the fire involves Class A or Class B materials, which this extinguisher rapidly suppresses.

⚠️ Application Limitations

Dry powder is not recommended for Class F cooking oil fires (deep-fryers or burning cooking pans in kitchens) as the pressurized blast can splash burning oil. Use an EN 1869 Certified Fire Blanket instead.

Dry chemical powder cannot extinguish thermal runaway in Lithium-Ion battery fires (e.g., PMDs, e-bikes, power banks).

Application & Regulatory Guidance

For Homeowners: Ideal for landed residences, home workshops, and garages. Portable fire extinguishers in private residential premises are not subject to mandatory annual FSM regulatory audits, but routine visual inspections of the pressure gauge are recommended every 6 months.

For Commercial Premises: Fulfills and exceeds baseline Class A fire hazard ratings under SS 578:2019 for office, commercial, and industrial spaces. The affixed serial label verifies third-party product listing under the accredited Product Listing Scheme (PLS).

✅ Ideal For: Commercial Offices, Warehouses, Retail Stores, Light Industrial Workshops, Storage Depots, Carpentry Yards, and Landed Properties

💡 Commercial Buying Tip: Under Singapore Standard SS 578:2019, commercial workspaces generally require a minimum 13A rating for general Class A fire hazards. This 4KG Dry Powder model carries a 34A rating, providing generous margin to satisfy workplace compliance requirements.

Standards & Third-Party Certification

Maintenance & Servicing Guidelines

Residential Use: Annual servicing is not mandatory for private residential properties. Standard portable extinguishers generally have an operating lifespan of up to 5 years before hydrostatic testing or replacement is advised by manufacturers. We recommend checking the pressure gauge once a month to ensure the needle remains in the green zone.

Commercial & Business Premises: Under Singapore Standard SS 578:2019, fire extinguishers deployed in commercial and industrial workplaces must undergo inspection and servicing at least once every 12 months by a qualified service provider. Units must be tagged with an up-to-date maintenance record label to satisfy workplace fire safety audits.
