FAQs

What types of fires is the CommanderEDGE 6 Litre Water Extinguisher suitable for?

This extinguisher is rated 13A and designed specifically for Class A fires involving solid combustible materials such as wood, paper, textiles, fabrics and other carbonaceous materials. It should not be used on Class B fires involving flammable liquids, Class C fires involving flammable gases, Class D fires involving combustible metals, or Class F fires involving cooking oils and fats.

Can this water extinguisher be used near electrical equipment?

The CommanderEDGE 6 litre water extinguisher has passed the 35kVa dielectric conductivity test in accordance with BS EN3-7:2004 Clause 9, demonstrating it has met the required electrical safety standards. However, water extinguishers should only be used on or near live electrical equipment if they specifically display the electrical safety symbol on the front label and contain demineralised water suitable for this purpose.

How does a water fire extinguisher work?

Water extinguishers work by cooling the burning material below its ignition temperature. When water is sprayed onto a fire, it absorbs large amounts of heat energy, rapidly reducing the temperature and preventing the fire from continuing to burn. The water penetrates deep into burning materials to ensure complete extinguishment and prevent re-ignition. This cooling action makes water extinguishers highly effective against Class A fires.

What makes the CommanderEDGE range stand out from other extinguishers?

The CommanderEDGE range from market-leading Commander offers BS EN3 Kitemark approval across all models, providing reassurance of dependable design and manufacture. These extinguishers feature high-quality brass valve assemblies, thick polyethene internal linings, strong plastic base skirts for protection, and corrosion-resistant finishes. Each unit is supplied with a 5-year warranty and full technical support, combining performance, quality and value for professional fire safety applications.

Why choose a water extinguisher over other types?

Water extinguishers remain the most popular choice for Class A fire risks due to their affordability, effectiveness, and environmental credentials. They contain no chemicals, leave no harmful residue, are easy to maintain and service, straightforward to refill, and simple to dispose of at end of life. Water is also the most economical extinguishing medium available, making water extinguishers a cost-effective solution for protecting premises against the most common type of fire.

What servicing does this extinguisher require?

All fire extinguishers require annual servicing by a qualified technician to ensure they remain in good working order and comply with fire safety regulations. The service includes checking the pressure gauge, inspecting the cylinder for damage or corrosion, examining seals and safety components, and verifying the unit is fully charged and ready for immediate use. Extended servicing is required every five years, involving internal inspection of the cylinder and valve mechanism.

Where are water fire extinguishers most commonly used?

Water fire extinguishers are suitable for any environment where Class A fire risks are present, including offices, schools, retail premises, warehouses, factories, hotels, public buildings and residential properties. They are ideal for areas containing combustible materials such as paper, cardboard, wood furniture, textiles and fabrics, but should not be placed in locations with significant electrical equipment, flammable liquid storage or commercial cooking facilities without appropriate additional extinguisher types.
