Hazard can be an object or a set of circumstances that could potentially harm a
person’s health. Risk is the likelihood, or probability, that a person will be harmed
by a particular hazard .
The more clearly the hazard is understood, the sooner a
safety procedure can be established. In the end, safety is a social choice that people,
governments, and organizations make. It assumes that the cost−benefit ratio is favorable, and that an option for minimizing exposure exists.
