Risk is the probability that an undesirable event will occur. It is often defined as the likelihood of a negative outcome and its consequences. Risk means the possibility that an event might occur. It does not mean that the event has already occurred.

A hazard has the potential to cause harm. A hazard becomes a risk when there is exposure to it. For example, when it is snowing heavily, then slippery roads, because of snow are a hazard. The risk of an accident increases when driving in such conditions.

Without hazard, there is no risk.
