4. 1.Background – Chemical Hazards & Risk EDMS No. ???Slide 4 of ## Hazard refers to the inherent properties of a chemical substance that make it capable of causing harm to a person or the environment. Exposure describes both the amount of, and the frequency with which, a chemical substance comes into contact with a person, group of people or the environment. Risk is the possibility of harm arising from a particular exposure to a chemical substance, under specific conditions.
