Which statement best defines risk?

• A. The cost of safety measures
• B. The probability of a hazard causing an incident
• C. The severity of potential harm
• D. The likelihood of harm arising from exposure to a hazard

Answer: (D)

In safety terms, risk is about the chance that someone will be harmed by exposure to a hazard. It isn’t just how bad the harm could be or simply that a hazard exists; it’s about the likelihood that harm will occur given people’s exposure to that hazard and how serious that harm could be. Think of a sharp edge as a hazard. If no one touches it or gets near it, exposure is low and so is the risk. If someone works near it without protection, exposure increases and so can the potential for harm. The statement that best defines risk reflects this likelihood of harm arising from exposure to the hazard. The other ideas don’t fit because they focus only on the severity of harm, or only on the existence of the hazard, or on the cost of safety measures. Risk is specifically about the chance of harm occurring due to exposure to a hazard.
