Hazard Class 4 covers which category?

• A. Poisons/Infectious Substance Class
• B. Organic Peroxide Class
• C. Flammable/Combustible Solids Class
• D. Explosives and Blasting Agents Class

Answer: (C)

Hazard Class Four is about solids that pose a fire risk because they ignite easily. This includes flammable solids that can catch fire from friction or heat, substances that may ignite spontaneously, and materials that release flammable gas when in contact with water. In this set, the descriptor that fits Class Four is Flammable/Combustible Solids. The other options point to different hazard classes: poisonous/infectious substances belong to a different class, organic peroxides are treated as a separate oxidizing/reactive category, and explosives and blasting agents are classified as a separate class altogether.
