Designated Substance

Last updated: October 13, 2016

What Does Designated Substance Mean?

Designated substances are specifically identified hazardous chemicals that require special considerations when working with or near said chemicals. These considerations include determining the existence of the chemical, conducting an assessment, reviewing handling and application, and developing controls to minimize or eliminate the hazard.

Safeopedia Explains Designated Substance

A designated substance is typically determined by a government agency. Such chemicals include arsenic, asbestos, benzene, lead, mercury, and silica. A review of the chemical inventory will aide in identifying the presence of the majority of these substances. Once the hazard is determined to be present, an assessment must be performed that will outline the acceptable use, handling, storage and disposal instructions. Once this consideration is made, the level of exposure must be evaluated to determine if there are specific control methods that should be considered. Control methods can include elimination of the hazard, engineering controls, or personal protective equipment.
