Indoor Air Quality

OCCUPATIONAL & ENVIRONMENTAL HYGIENE ASSOCIATES (OEHA) industrial hygiene professionals perform routine indoor air (IAQ) quality investigations to identify complaint sources in buildings. The frequency of complaints related to Sick Building Syndrome (SBS) and Building Related Illness (BRI) have increased dramatically. Indoor air quality problems can be complex resulting from the many dynamic interactions in a facility. The more appropriate descriptor or label is Indoor Environmental Quality (IEQ). Some of the interacting factors may include lighting, ergonomics, noise and stress. Often times complaints about indoor air may in fact be related to a combination of issues. OEHA will help you address these concerns through cost effective solutions that solve the problem not simply treat the symptoms. We will work with you to resolve your IEQ issues while simultaneously creating an awareness among your management team and staff.

OEHA industrial hygiene professionals use state-of-art testing procedures to test volatile organics, semi-volatile organics, aldehydes, metals, polynuclear aromatic hydrocarbons, pesticides, herbicides, inorganic acids, particulate, mold, pollen, antigens and other contaminants. Laboratories used by OEHA are among the most highly qualified and reputable laboratories in the nation.

OEHA industrial hygiene professionals are well qualified to perform evaluations of local exhaust and general dilution ventilation systems and HVAC systems to detemine operating efficiencies. Outdoor fresh air supply to the building envelope is routinely evaluated using carbon dioxide, temperature and relative humidity indices.
