A hazard refers to anything that has the potential to cause harm. In the case of electrical arc, the potential to cause harm will vary depending on many factors. A risk is the likelihood- high or low - that someone/something might be harmed by the hazard.
a. what could cause injury or harm
b. whether the hazards could be eliminated and, if not,
c. what preventive or protective measures are, or should be, in place to control the risks.
At DuPont, we use the "4P" approach to risk assessment.
