Which of the following is NOT considered a physical hazard of hazardous materials?

• A. Corrosivity
• B. Flammability
• C. Reactive properties
• D. Odor

Answer: (D)

Odor is not considered a physical hazard of hazardous materials. Instead, it is often regarded as a sensory characteristic that can provide an indication of the presence of a chemical or compound. While an odor can signal that a hazardous material is present, it does not directly represent a risk or danger in the same way that corrosivity, flammability, and reactive properties do.

Corrosivity refers to a material's ability to cause destruction of living tissue or severe corrosion of material, which presents a clear physical hazard. Flammability indicates how easily a substance can ignite and catch fire, posing significant risks in emergency situations. Reactive properties describe how a substance may react with other materials, potentially leading to hazardous situations such as explosions or the release of toxic gases. These characteristics directly relate to the physical dangers posed by hazardous materials, while odor simply serves as an indicator of potential hazards without being an inherent physical risk.
