Air Contaminants Initiative

Hazardous chemicals (e.g. air contaminants) are present in almost every work environment.  These contaminants can have a profound negative effect on the health of workers which may reduce productivity and the profitability of a business.  The following resource has been developed to assist employers and employees in identifying air contaminants present in the work environment and determining the best way to anticipate, evaluate, control or eliminate those hazards.
