Morphology

nonhazardous = hazardous (transparent) = non + hazard + ous

The prefix 'non-' clearly negates the meaning of 'hazardous'.

Etymology

Nonhazardous begins with non- meaning 'not' and the part hazard, which means 'danger' or 'risk' and once named a dice game that stood for 'chance'. So nonhazardous means 'not dangerous' or 'not likely to cause harm'.
