Which statement best defines risk in occupational health?

• A. Risk is simply the hazard itself without considering exposure.
• B. Risk is the same as hazard.
• C. Risk is only the frequency of exposure without considering severity.
• D. Risk is the likelihood and severity of harm given exposure.

Answer: (D)

Risk in occupational health is the chance that harm will occur as a result of exposure to a hazard, considering both how likely the harm is and how severe it would be under the actual exposure conditions. It's not just the hazard itself; exposure and the potential consequences drive the real level of risk. A highly hazardous substance with minimal exposure can pose low risk, while substantial exposure to a less hazardous substance can still produce meaningful risk. By combining probability of harm with the severity of that harm given exposure, you capture the true likelihood and impact of adverse health effects.
