A RISK is the chance that someone or something could be harmed by a hazard.

Explanation:

Risk is the probability of experiencing harm or an adverse side effect from exposure to a hazard, may it be from the workplace, environment, or property.

Hazard is anything that may be a source of possible harm or damage to an individual or property.

Risks within the workplace are assessed to prevent workers from possible exposure or damage, this is called Risk Assessment Control. Here, the  likelihood of a hazard occurring is determined.

An example is medication errors when the nurse/s are overworked.

"Overworked nurses are 15 times (for example) more likely to commit medication errors  than fully-rested nurses."

The likelihood of developing such errors depends on multiple factors like:

"Too much work load"

"Huge number of patients"

"Lack of manpower"
