Which hazmat type includes substances that can cause corrosion?

• A. Corrosives
• B. Toxins
• C. Aerosols
• D. Oxidizers

Answer: (A)

Corrosion is the defining hazard here: hazmat types are built around the specific damage a material can cause, and substances that can cause corrosion are classified as corrosives. Corrosives chemically attack metals and living tissue, so the label directly signals the ability to cause corrosion. This makes it the best answer because it explicitly describes the hazard in terms of corrosive action, not merely how the substance is delivered or its other health effects. Toxins describe harmful effects to living organisms, aerosols indicate a dispersed form, and oxidizers are substances that release oxygen or promote combustion; none of these by themselves define a capability to corrode metals or skin in the way corrosives do.
