Protective Action Criteria (PACs) are exposure guidelines used during chemical emergencies to help protect the public from health effects of short-term exposures to hazardous chemicals in the air. PACs are used by government agencies and the private sector to evaluate the potential impact of a one-time rare exposure to a chemical. Alberta Health conducted a review and prepared a report to provide background information for health professionals who may use protective action criteria. The main objectives of this report are to provide background information on PACs, present a summary of real-world usage of PACs, and discuss the advantages and limitations associated with these guidelines.
