Which HAZMAT class includes flammable solids?

The classification of hazardous materials is critical for ensuring proper handling and safety procedures. Flammable solids fall under Class 4, specifically known as "Flammable Solids." This class is designed to include materials that can catch fire easily and sustain combustion, which poses risks during transport and storage.

Understanding the nature of these substances is essential for firefighters and hazardous material responders. Flammable solids can ignite through friction, moisture retention, or other means, making proper identification and management important in an emergency.

In contrast, other classes such as Class 3 refer to flammable liquids, Class 5 covers oxidizers and organic peroxides, and Class 6 pertains to toxic substances. Each of these classes has unique properties and hazards, necessitating tailored approaches to handling and response procedures. Recognizing the characteristics of each class, especially Class 4 for flammable solids, is vital for effective hazard assessment and ensuring safety during HAZMAT situations.
