D Class Powder fire extinguishers are used for fighting metal fires. Whether it is an naturally reactive metal like potassium or just waste cuttings and swarf, metal fires are very dangerous and are easily spread by the use of a high pressure extinguisher.
D class powders have a specially formulated extinguishant to deal with the reactive properties of metal fires, and are easily distinguished by the Low Velocity Applicator – meaning that the powder gently falls onto the fire, while the operator stands at a safe distance.
M28 Powder is suitable for use on all metal fires except lithium, while L2 Powder can be used on all metal fires including lithium.
