Details on fire class D
Dangers of class D fires
Class D fires are particularly dangerous as they are caused by combustible metals. These metals often react violently with water, oxygen and other common extinguishing agents, which makes the fires difficult to control and can cause potentially dangerous reactions. For example, water hitting a metal fire can break down into hydrogen and oxygen, which can intensify the fire and cause an explosion.
Special extinguishing agents for class D fires
Class D fires require special extinguishing agents known as metal fire powders. These powders work by isolating the metal from the oxygen source to stop combustion. Two common types of metal fire powders are sodium chloride (NaCl)-based powders and graphite-based powders. Each powder is tailored to specific metal fires, so it's important to choose the right extinguishing agent for the specific metal present in your environment.
Are battery or accumulator fires class D fires?
Battery or accumulator fires are generally not class D fires. They are often referred to as thermal overload or running fires and usually fall under Class C, which stands for fires caused by electrical equipment. These fires also require special treatments and extinguishing agents. While some metal fire powders can be effective on certain types of battery fires, it's important to make sure the extinguishing agent you choose is appropriate for the specific fire you're trying to fight.
Buying class D fire extinguishers
Suitability of class D fire extinguishers
Class D fire extinguishers are specifically designed to fight fires caused by combustible metals. This type of fire is often found in industrial environments where metals such as magnesium, aluminum, sodium or potassium are processed.
Criteria when buying a class D fire extinguisher
Effectiveness and capacity
- Check the capacity of the extinguisher and its effectiveness against the specific metals you are working with.
- Make sure that the extinguisher contains a sufficient amount of extinguishing agent to effectively fight the potential fire.
Certification and standards
- Make sure that the fire extinguisher is approved according to the applicable standards and certifications in your country or region.
- Make sure that the product has the required safety markings and instructions.
Shelf life and maintenance
- Check the expiration date of the fire extinguisher. Most fire extinguishers must be replaced or serviced after a certain number of years.
- Find out about the maintenance requirements of the extinguisher. Some extinguishers require regular inspections and maintenance to ensure that they work properly when needed.
