Class D Fires: Understanding the Risks and Extinguishing Techniques
In the firefighting industry, fires are classified into different categories based on the type of fuel that is burning. One of these categories is Class D fires, which are defined as fires that involve combustible metals such as aluminum, magnesium, titanium and other similar metals.
Class D fires are particularly challenging to extinguish because of the unique properties of the burning metals, which can cause intense heat and release toxic fumes. These types of fires can occur in industrial and laboratory settings, and can be caused by a variety of factors such as human error, equipment malfunction, and chemical reactions.
To extinguish Class D fires, firefighters typically use special dry powder extinguishers specifically designed for combustible metals. These agents smother the fire by creating a barrier between the burning metal and the oxygen, and also cool down the metal. They also use special tools such as tongs and shovels to remove the burning metal, which can be safely transported to a safe area.
In addition to using extinguishing agents, firefighters also use other techniques such as isolation and ventilation to control the fire. They also use safety equipment such as full face piece self-contained breathing apparatus (SCBA) to protect themselves from toxic fumes.
Overall, understanding Class D fires and how to extinguish them is crucial for firefighters and is an essential part of firefighting operations. It’s important to note that Class D fires are not common, and it’s important to have a proper training and equipment to handle them.
