Hazard Meaning

The word hazard definition is very difficult to explain since it is mixed with other terms like danger and risk. We can define hazard as a cause or source of potential loss/danger. Hazard can be a situation or an object that may cause harm to personnel or property if handled improperly.

If a person is working on height there is hazard of fall that could lead to death or injury. If welding work is being done there is a fire hazard, there can be fire if proper measures are not taken. In short we can say that ” A Hazard Can Cause Damage or Harm“.
