How do you differentiate between a hazard and a risk?

• A. A hazard is the actual harm; risk is the probability and severity of harm resulting from exposure to the hazard.
• B. A hazard is a source with potential to cause harm; risk is the probability and severity of harm resulting from exposure to the hazard.
• C. A hazard is a source of safety; risk is the mitigation action.
• D. Hazard and risk are the same concept.

Answer: (B)

Understanding the difference between hazard and risk is key. A hazard is a source or situation with the potential to cause harm. It’s about what could go wrong, not that it has already happened. Risk, on the other hand, describes how likely it is that harm would occur and how severe that harm could be if exposure to the hazard happens. In other words, risk combines both the chance of harm and the seriousness of that harm, given how people might be exposed and what controls are in place. So a broken ladder or a chemical without proper labeling are hazards because they have the potential to cause injury. The risk would be the likelihood of someone getting hurt from using the broken ladder or from exposure to the chemical, taking into account how often it’s used, the degree of exposure, and what safety measures exist (like training, PPE, or guards). This is why the correct description emphasizes hazard as a source with potential to cause harm and risk as the probability and severity of harm from exposure. The other ideas mix up harm with the potential or mislabel controls, which isn’t accurate.
