Any real or potential condition that can cause injury, illness, or death to personnel; damage to or loss of a system, equipment, or property; or damage to the environment. Thus, the hazard can become a cause of accident or risk and it can exist without accident or risk. When due to hazard, an accident happens, it is converted into an accident. If a hazard still exists, an accident may happen again. (Hazard is a condition that might cause an accident or risk and harm to people, property, and environment).
