Which of the following is NOT a hazard category?

• A. Physical hazard
• B. Environmental hazard
• C. Atmospheric hazard
• D. Chemical hazard

Answer: (D)

This item tests how hazard categories are grouped in a specific risk classification. The listed categories separate dangers by broad kinds of threat: physical hazards cover energy-related dangers like moving machinery or slips; environmental hazards involve impacts on the environment, such as pollution or contamination; atmospheric hazards pertain to risks in the air we breathe, like smoke or toxic gases. Chemical hazard, while real and important, isn’t included as its own category in this particular scheme. In some frameworks chemical risks are treated under a broader physical/chemical umbrella or as a distinct category in other contexts, but here the set uses three specific categories, leaving chemical hazard out. So chemical hazard is the one that doesn’t fit this list.
