Which of the following is best definition a hazard?

A hazard is a source or situation with the potential to cause harm or damage. In the context of risk management, a hazard can be defined as any event or condition that has the potential to cause injury, illness, damage to property, or loss of business. Hazards can be natural, such as earthquakes or floods, or man-made, such as industrial accidents or chemical spills.

Some of the other options provided are incorrect because they do not specifically address the concept of potential harm or damage. For example, "A hazard is a source of danger" is too broad and does not provide any specific criteria for what constitutes a hazard. "A hazard is a risk that has not yet occurred" is also incorrect because a hazard does not necessarily have to be a risk; it simply has the potential to cause harm or damage.
