Indoor Air Quality Indoor air quality (IAQ, also called "indoor environmental quality") describes how inside air can affect a person's health, comfort, and ability to work. It can include temperature, humidity, lack of outside air (poor ventilation), mold from water damage, or exposure to other chemicals. Indoor Air Quality Hazard Overview Solutions Regulations Learn More What hazards are associated with indoor air quality? Poor indoor air quality can lead to a variety of symptoms. Some workers complain about symptoms that happen at work and go away when they leave work, like having headaches or feeling tired. Fever, cough, and shortness of breath can be symptoms of a more serious problem. Asthma and some causes of pneumonia (for example, Legionnaires’ Disease and Hypersensitivity Pneumonitis) have been linked to IAQ problems. What can I do to protect myself? If a specific air contaminant is known to be present, ask your employer if any air monitoring has been done and if so, ask for a copy of the test results. If you observe the sudden appearance of mold on walls or begin to experience symptoms such as irritation of the throat or other respiratory symptoms, bring this to the attention of your employer. What resources are available to assist employers? Training and Outreach Services Related presentations on hazard communication and toxic and hazardous substances are available for employers to use to train their employees. These presentations should be customized to fit the conditions and hazards identified in the worksite. In addition, the education, training and technical assistance bureau provides free online safety and health training and outreach services (i.e., speaker's bureau requests, safety booths) upon request. Lastly, the NCDOL Library offers free safety and health videos (including streaming video services) and related research assistance on consensus standards (i.e., ANSI, NFPA, NEC). Safety and Health Programs This example program for hazard communication can also assist the employer with the development of a program. A-Z Topics Other resources can be found on the A-Z topics page for hazard communication. Consultation Services The consultative services bureau provides free and confidential onsite consultation regarding worksite safety and health hazards. Which standards apply? There are no specific OSHA or N.C. occupational safety and health standards for Indoor Air Quality. However, specific OSH Division standards may apply to particular contaminants.
