Which class of hazardous material is identified as flammable solids?

The classification of hazardous materials is based on their physical and chemical properties, which is essential for ensuring safety during transport, storage, and handling. Flammable solids fall within Class 4 of the hazardous materials classification system. This class specifically includes substances that are solid and can ignite quickly, presenting a significant fire hazard when exposed to a flame or heat source.

Flammable solids can easily catch fire under normal conditions, and their combustion can lead to severe consequences, making it crucial for responders and handlers to recognize them as such. Understanding this classification helps emergency responders develop appropriate handling and response strategies when dealing with incidents involving these materials.

In contrast, the other classes pertain to different types of hazards: Class 5 encompasses oxidizers, which can enhance the combustion of materials, Class 6 includes toxic and infectious substances, and Class 7 pertains to radioactive materials. Each of these classes presents unique risks that are distinctly different from those associated with flammable solids.
