Indoor Air Quality Checklist

Indoor air quality (IAQ) references the quality of air in a home, school, office, or any other building. The concentrations of some pollutants indoors can be up to five times higher than typical outdoor concentrations, which can be detrimental to the health of the immunocompromised. The performance of hazard surveillance rounds, as it relates to IAQ, provides a key opportunity to identify IAQ issues. This checklist can be used to supplement hazard surveillance rounds and incorporate items related to IAQ.
