CommanderEDGE | 4kg ABC Dry Powder Fire Extinguisher

FAQs

What types of fires can the CommanderEDGE FX-PWD-004-DCF extinguish?

This ABC powder fire extinguisher is designed for Class A fires (combustible solid materials such as wood, paper, textiles and plastics), Class B fires (flammable liquids including petrol, oils, paints and solvents in open spaces), and Class C fires (flammable gases such as propane, butane and methane). The ABC powder works by smothering fires with a thick barrier between fuel and oxygen whilst interrupting the chemical reaction of combustion, providing excellent knock-down properties. It should not be used in confined spaces as the powder can be easily inhaled, and is not suitable for Class F fires (cooking oils and fats in deep fat fryers).

What does the 21A 89B C fire rating mean?

The 21A 89B C rating indicates this extinguisher’s enhanced multi-purpose capability. The 21A rating shows effectiveness on Class A fires involving 21 layers of wooden cribs in testing, the 89B rating demonstrates capability on Class B flammable liquid fires covering 89 square decimetres, and the C rating confirms suitability for Class C flammable gas fires. This represents a significant performance increase over smaller capacity models, making it suitable for larger fire risks whilst maintaining portability for transport applications.

What are MED and MER approvals?

MED (Marine Equipment Directive 2014/90/EU) and MER (Marine Equipment Regulations) are certifications that confirm the extinguisher meets stringent quality and safety standards for maritime applications. MED-approved equipment is marked with the ‘Wheelmark’ symbol, whilst MER-approved equipment features the ‘Red Ensign’ flag symbol. These approvals make the FX-PWD-004-DCF suitable for use on vessels and in marine environments as well as land-based applications, providing versatile fire protection across diverse settings including boats, ships, and offshore installations.

What makes CommanderEDGE different from standard Commander extinguishers?

CommanderEDGE represents the premium tier within the CheckFire portfolio, offering BS EN3 Kitemark approval across the entire range as assurance of dependable design and manufacture. The CommanderEDGE range has become the choice of professionals, offering a reassuring mixture of performance, quality and value. The internationally-recognised BS Kitemark provides additional quality assurance beyond standard certification, confirming that the extinguisher has been manufactured to the highest standards and undergone rigorous testing by the British Standards Institution.

Why is the 4kg size ideal for transport applications?

The 4kg capacity provides substantial fire-fighting capability with its impressive 21A 89B C rating, whilst remaining portable enough for mobile applications. At 6.9kg total weight, it offers an optimal balance for vehicles, vans, trucks, and mobile equipment where space may be limited but comprehensive fire protection is required. The multi-purpose ABC rating means a single extinguisher can tackle the various fire risks associated with transport environments, including fuel fires (Class B), cargo fires (Class A), and gas system fires (Class C).

What is the operating temperature range?

This extinguisher operates effectively across a temperature range of -20°C to +60°C, making it suitable for all-year-round external situations and environments subject to temperature variations. Unlike water-based extinguishers which typically operate from +5°C upwards, powder extinguishers can function reliably in sub-zero conditions, making them ideal for outdoor locations, unheated buildings, vehicles, and mobile equipment where temperatures may drop below freezing during winter months or vary significantly throughout the day.
