What kind of materials are classified as "Class 3" hazardous materials?

Class 3 hazardous materials are defined as flammable liquids, which are substances that can easily ignite and produce fire. This classification is particularly important for first responders, such as those in the FDNY Hazardous Materials team, as it indicates that these liquids pose a significant risk if not handled properly. Flammable liquids can include a wide range of substances, such as gasoline, alcohol, and certain solvents, which can emit vapors that ignite at relatively low temperatures.

Understanding the properties of Class 3 materials is essential for effectively managing incidents involving them, including fire prevention, containment, and appropriate firefighting techniques. Flammable liquids can lead to explosive fire hazards, so recognizing their classification assists responders in assessing the risk and implementing safety measures.

The other classifications include corrosive substances, which can chemically burn or damage living tissue or materials upon contact; explosive materials, which can detonate or explode upon certain conditions; and toxic gases, which can cause harm or death due to inhalation. However, these substances belong to different classes and require different handling and response protocols.
