A potential source of harm or adverse health effect on a person or persons is called Hazard.

The Hazard and Risk terms are normally used interchangeably but the following simple example explains the difference between these two.

If there was a spill of water on the floor then that water would present a slipping hazard to persons passing through it. If access to the area was prevented by some physical barrier then the hazard would remain though the risk would be minimized.
