Under the Health Protection and Promotion Act, which statement defines a health hazard?

• A. A condition of a premises
• B. A substance, thing, plant or animal other than man
• C. A solid, liquid, gas or combination of any of them that has or that is likely to have an adverse effect on the health of any person
• D. All of the above

Answer: (C)

The essential idea is that a health hazard is defined by its potential to harm health. The test looks for the criterion that the hazard has or is likely to have an adverse effect on the health of any person. Describing a solid, liquid, gas, or a combination of them that has or is likely to have such an adverse effect matches this definition precisely. Statements about a condition of a premises or about a substance, thing, plant or animal are examples of possible sources, but they don’t themselves state the defining test; they only become health hazards if they actually have or are likely to have an adverse health effect. Therefore, the statement that directly expresses the adverse-health-effect criterion is the correct definition.
