What are the three categories of hazardous materials hazards?

The correct categorization of hazardous materials hazards is based on the nature and impact of these materials in various environments. Among the options presented, thermal, mechanical, and etiological hazards each represent distinct types of risks associated with hazardous materials.

Thermal hazards relate to extreme temperatures that can cause burns or other heat-related injuries when dealing with heat-generating or heat-absorbing materials. Mechanical hazards focus on potential injuries that may occur from the physical equipment or the behavior of hazardous materials under physical stress. Etiological hazards refer to biological agents that can cause infectious diseases or other health issues.

Understanding these categories is crucial for effective handling, response, and mitigation during hazardous material incidents, preparing first responders to recognize and address the specific threats posed by different materials encountered.

While the other options include valid categories of hazardous materials, they do not align with the defined classifications of hazards as effectively as thermal, mechanical, and etiological. It is important for those in the field to familiarize themselves with these distinctions to enhance safety protocols and response strategies.
