Which of the following is NOT considered a part of hazardous materials?

Civilian equipment is not classified as a part of hazardous materials because it typically refers to non-toxic items and devices used in daily activities that do not pose a significant risk to health or the environment. In contrast, hazardous materials include substances that can pose risks such as chemicals, biological agents, and waste products.

Chemicals can be hazardous if they are toxic, corrosive, flammable, or reactive, which can result in damage to living organisms or the environment. Biological agents, such as pathogens and toxins, can cause diseases or adverse health effects. Similarly, waste products often contain hazardous substances that can be harmful during disposal or if released into the environment. The classification of civilian equipment as non-hazardous helps to distinguish everyday items from those that need to be handled with special care due to their potential dangers.
