Answer:
A RISK is the chance that someone or something could be harmed by a hazard.
Explanation:
Risk is the <u>probability of experiencing harm or an adverse side effect from exposure to a hazard</u>, may it be from the workplace, environment, or property.
Hazard is anything that may be a <u>source of possible harm or damage</u> to an individual or property.
Risks within the workplace are assessed to prevent workers from possible exposure or damage, this is called <u>Risk Assessment Control</u>. Here, the <u>likelihood of a hazard occurring is determined</u>.
An example is medication errors when the nurse/s are overworked.
<em>"Overworked nurses are 15 times (for example) more likely to commit medication errors than fully-rested nurses."</em>
The likelihood of developing such errors depends on multiple factors like:
<em>"Too much work load"</em>
<em>"Huge number of patients"</em>
<em>"Lack of manpower"</em>
