Workplace exposure standards are ai

Workplace exposure standards are airborne concentrations of a particular chemical or substance in the workers’ breathing zone that should not cause adverse health effects or cause undue discomfort to nearly all workers. Exposure standards are legal concentration limits that must be adhered to.

A person conducting a business or undertaking (PCBU) must ensure that a worker is not exposed to airborne contaminants above the workplace exposure standard. The official list of workplace exposure standards for airborne contaminants is contained within the publication Workplace Exposure Standards for Airborne Contaminants. Workplace exposure standards are also available within the Hazardous Substances Information System database here. This database contains additional information and guidance for many substances.
