The company ensures that all its products are nonhazardous and environmentally friendly.
Nonhazardous → It is formed from "non-" (meaning not) and "hazardous" (from Old French *hasard*, meaning risk or danger). The word "nonhazardous" means not involving risk or danger.
Think of 'not' ('non-') being combined with 'risk' ('hazardous') to remember that nonhazardous means something that does not pose a risk.
