Chemical and Biological Substances
“Biological substance” means a substance containing living organisms or parts of living organisms in their natural or modified forms. “Chemical substance” means any natural or artificial substance, whether in the form of a solid, liquid, gas or vapour, other than a biological substance. These types of exposures most commonly include workplace exposures to welding fumes, solvents, dusts and gasses.
Chemical exposures are often not seen as important as “safety” but statistics show that more people die from chemical exposures than industrial accidents.
