INDOOR ENVIRONMENTAL QUALITY
Health Hazard Evaluations
NIOSH conducts investigations of possible health hazards in the workplace. These investigations, called Health Hazard Evaluations (HHEs), are conducted under the authority of the Occupational Safety and Health Act of 1970 and the authority of the Mine Safety and Health Act of 1977, which authorize the Secretary of Health and Human Services, following a written request from employees, authorized representative of employees, or employers, to determine whether any substance normally found in the place of employment has potentially toxic effects in such concentrations as used or found.
NIOSH researchers have conducted many HHEs related indoor environmental quality issues. To learn about our evaluations and findings, go to the HHE database and search on a related term. To learn more about the HHE program, go to https://www.cdc.gov/niosh/hhe/about.html.
