How do you extinguish a Class D fire?
To effectively fight a class D fire, you should use a dry powder fire extinguisher. Dry powder extinguishers will smother the oxygen from the fire, meaning it cannot maintain itself or grow any further.
What is a Class D extinguishing agent?
A Class D fire extinguisher is used on combustible metals, such as magnesium, titanium, sodium, etc., which require an extinguishing medium that does not react with the burning metal. These extinguishers are identified by the letter K.
Are Class D fires hard to extinguish?
Unless you work in a laboratory or in an industry that uses these materials, it is unlikely you’ll have to deal with a Class D fire. It takes special extinguishing agents (Metal-X, foam) to fight such a fire.
What is a Class D fire and how are those types of fires extinguished?
Class D fires involve combustible metals, such as magnesium, titanium, and sodium. Extinguishers with a D rating are designed to extinguish fires involving combustible metals. Note: Common extinguishing agents may react with a combustible metal fire causing the severity of the fire to increase.

Which is the most common type of Halon extinguishing agent?
Halon 1211 is a “streaming agent,” and more commonly used in hand-held extinguishers because it discharges mostly as a liquid stream.
How does DCP extinguish fire?
Dry chemical extinguishers put out fire by coating the fuel with a thin layer of dust, separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out fire.
Which type of extinguishing agent is used to extinguish a Class B fire?
CO2
CO2: A carbon dioxide fire extinguisher works on a Class B fire by expelling CO2 to suffocate the fire, removing the oxygen necessary to keep it burning. It also helps with removing the heat, as the discharge is very cold.
How do Halon and Halon replacement agents extinguish fire?
Halon is a liquefied, compressed gas that extinguishes fires by reacting with the fire’s elements and breaks the chemical chain reaction. A fire needs three elements to sustain – oxygen, heat, and fuel. When you disrupt or remove an element, the fire cannot sustain itself.
