Hazard and Risk

Hazard refers to potential for harm and risk refers to chances of being harmed under real-world conditions. Sharks are a hazard. They are fierce predators with sharp teeth, and have attacked humans in the past, but for most people, sharks are not a risk.

If you are swimming in a tank full of sharks, your risk is high. If you are mowing your lawn, your risk is low. The hazard does not change.
