This type of extinguisher is designed for areas requiring heavy-duty fire protection, and the wheels allow for easy movement across different work environments.
It is suitable for Class A fires (involving solid materials like wood, paper, and fabric) and Class B fires (flammable liquids).
The foam works by forming a stable, cooling blanket over the surface of the fire, which cuts off the oxygen supply and prevents re-ignition.
The extinguisher shown is CE certified and Kitemarked to BS EN3 standards.
