What is the difference between a hazard and a risk?

• A. A hazard is a source of potential harm; risk is the likelihood and consequence of that harm occurring.
• B. Hazard is the probability of harm; risk is the severity of harm only.
• C. Hazard and risk are identical concepts.
• D. Risk is a physical hazard, while hazard is a financial risk.

Answer: (A)

Understanding the difference between a hazard and risk is essential in safety management. A hazard is a source or situation with the potential to cause harm. Risk, on the other hand, combines that potential with how likely the harm is to occur and how severe the consequence would be if it does, taking into account exposure and controls in place. This aligns with the idea that risk depends on both the probability of an event and the severity of its outcome. For example, a hot surface is a hazard because it can cause burns. The risk of injury from that hazard depends on how likely someone is to touch it and how bad the burn would be, which can be reduced by using guards, signs, or training. Other statements are not accurate because hazard is not the probability of harm, and risk is not solely about severity or solely about probability. Hazard and risk are not the same thing, nor are they limited to physical versus financial contexts.
