An etiological hazard is best described as:

An etiological hazard is best described as:

• A. Exposure to microorganism or its toxin
• B. Exposure to heat
• C. Mechanical hazard
• D. Chemical hazard

Answer: (A)

Etiological hazards involve biological agents that can cause disease—such as microorganisms or the toxins they produce. This is why exposure to a microorganism or its toxin best describes an etiological hazard: it centers on biological matter that can lead to illness. Other types of hazards cover heat (thermal hazards), mechanical hazards from physical objects or equipment, and chemical hazards from hazardous substances, which are not about disease-causing biological agents.
