OSHA does not have a specific indoor air quality (IAQ) standard for construction or general industry activities, but does provide guidelines addressing the most common workplace complaints about IAQ. These are typically related to temperature, humidity, lack of outside air ventilation, or smoking. OSHA standards address potential hazardous conditions leading to serious physical harm or death. Such standards may include those for specific air contaminants, ventilation systems, or the General Duty Clause of the Occupational Safety and Health Act of 1970 (OSH Act).

For guidelines and additional information on this subject, see OSHA's Safety and Health Topics page on Indoor Air Quality and Frequently Asked Questions about Indoor Air Quality.
