The US EPA has sited poor indoor air
quality as one of the four greatest risks to human health. It is only within the past 30
years that problems with indoor air quality and pollutants have surfaced. In response to
the energy crisis of the 1970s, buildings were designed to minimize heat loss with sealed
windows and insulated walls. In addition to minimizing heat loss, the energy conserving
features significantly reduce the amount of fresh air that was allowed to enter these
buildings. Without the removal of stale air or the addition of fresh air, contaminants,
irritants and hazardous odors or gases could not be removed or diluted to safe levels. Our staff of industrial hygienists have received formal training in
aspects of indoor air quality that are critical to solving problems that face many
facility owners and managers. Areas of expertise include on-site investigative techniques,
evaluation of the heating, ventilation and air conditioning (HVAC) systems, determining
possible contaminant sources and industrial hygiene sampling and analysis.
