Which of the following is true for hazmat class 4?

Hazmat class 4 is specifically designated for flammable solids. This classification includes materials that can ignite spontaneously or are readily combustible when exposed to heat or an ignition source. Flammable solids can pose significant fire hazards, especially when they are present in large quantities or in environments where they can easily come into contact with flames or heat sources.

In contrast, corrosive materials fall under a different classification, which typically includes hazmat class 8. Oxidizers, which support combustion and can intensify fires, are classified under hazmat class 5. Non-flammable liquids belong to class 3, which is focused on flammable liquids. Understanding these classifications is essential for safely transporting and handling hazardous materials and following the appropriate regulations regarding each type.
