Final answer:
A hazard is a potential source of harm or danger, a risk refers to the likelihood of harm, and an incident is an unexpected event causing harm or damage.
Step-by-step explanation:
A hazard is a potential source of harm or danger that can cause injury, illness, or damage to property or the environment. Examples of hazards in the context of safety can include physical hazards (such as sharp objects or slippery floors), chemical hazards (such as toxic substances or flammable materials), and biological hazards (such as infectious diseases or biohazards like bloodborne pathogens).
A risk, on the other hand, refers to the likelihood or probability that a hazard will actually cause harm. It involves assessing the potential consequences of exposure to a hazard.
An incident, in the context of safety, refers to any unexpected or unplanned event or occurrence that results in harm, injury, illness, or damage. It could be an accident, a near miss, or any other event that deviates from the norm and has safety implications.
