Metal fires occur when unstable metals are brought to their ignition temperature and there is a source of ignition. For instance, a car fire could ignite certain metallic components used in engines or exhaust systems.
Flammable metals include lithium, magnesium, and even shredded or powdered aluminum.
Class D fire extinguishers contain chemicals designed to extinguish metal fires.

What are two common fire extinguishers that are ineffective on alkali metal fires?
Water and carbon dioxide fire extinguishers are ineffective on alkali metal fires because they can react violently with alkali metals, such as sodium or potassium, and actually make the fire worse. It is recommended to use a Class D fire extinguisher specifically designed for metal fires in this case.
Why are flammable chemicals stored in a metal cupboard?
Flammable chemicals are stored in a metal cupboard to reduce the risk of fire. Metal is non-combustible and helps contain fires if the chemicals ignite. It also provides some level of protection from external heat sources.

Why cant dry powder be used on metal fires?
Dry powder fire extinguishers are generally effective for various types of fires, including those involving flammable liquids and gases. However, they are not suitable for metal fires (Class D fires) because certain metals, like magnesium or sodium, can react violently with the chemicals in dry powder extinguishers. These reactions can exacerbate the fire or create hazardous situations. Specialized extinguishing agents, such as sodium chloride or graphite powder, are required to safely extinguish metal fires.
