Which statement best defines hazard?

• A. Hazard is a device that emits radiation
• B. Hazard is a source or situation with potential for harm
• C. Hazard is a safety protocol
• D. Hazard is a measure of risk

Answer: (B)

Hazard means any source or situation with potential for harm. It highlights the possibility of injury, damage, or adverse health effects if someone is exposed, rather than something actively causing harm right now. Recognizing hazards helps us manage risk by removing them or reducing exposure, so harm is less likely. For rail safety, examples include an exposed live conductor, a wet platform, or a broken rail joint—each is a hazard because it could cause harm. The statement that hazards are sources or situations with potential for harm best captures this idea. The other options describe a specific device that emits radiation (an instance of a hazard, not the definition), a safety protocol (a method to prevent harm), or a measure of risk (a function of hazard plus exposure and consequences).
