Maintaining Acceptable Indoor Environmental Quality (IEQ) During Construction and Renovation Projects

NIOSH has conducted several Health Hazard Evaluations in workplaces with reported health concerns associated with construction and renovation in occupied buildings. During these evaluations, NIOSH investigators identified issues that could affect indoor environmental quality (IEQ) such as a lack of dust control, the use of high emission building materials, and limited communication with occupants about hazards related to the work being done. After its evaluations, NIOSH made detailed recommendations to help employers reduce exposures and maintain acceptable IEQ.
