Definition - What does Chronic Hazard mean?
A chronic hazard is one that carries with it the potential for a cumulative, long term impact. Often the effects of the hazard are hidden until they cause serious health complications.
Safeopedia explains Chronic Hazard
A chronic health effect will usually develop slowly. Since there are no acute effects, the affected person often continues exposure unaware of the cumulative build-up of the effect. An example is breathing small amounts of asbestos fibers. You do not notice inhaling them and there are no acute effects. Over time, however, the person may develop lung cancer or other respiratory illnesses.
