This is supplemented by specialized training in industrial hygiene. The science of industrial hygiene is dedicated to anticipating, recognizing, evaluating and controlling the causes of occupational illness. Since industrial hygienists are trained to evaluate environments for factors that affect health and comfort, qualified industrial hygienists are key members in most indoor air quality investigations. Engineers are invaluable in understanding the intended design parameters of HVAC systems. Their input is essential when it comes to designing retrofits to existing HVAC systems to improve indoor air quality.
Architects are in a position to understand how building design can affect indoor air quality.
They are also responsible for specifying interior building finishes and building components which are part of the total IAQ equation. Look for an architect with formal training or experience in preventing indoor air quality problems. Occupational physicians and occupational health nurses have specific training in aspects of the work environment, and can help IAQ investigators target potential sources of health complaints. Although occupants may identify these symptoms as being related to building air quality, some of these reports may actually be associated with improper lighting, noise or poorly designed work stations. Many industrial hygienists have the expertise to assess and resolve most lighting, noise or ergonomic problems.
