Indoor Air Quality Studies

HygieneTech offers a full range of services devoted to investigating the specific cause(s) of compromised air quality within structures. Our staff occupational health professionals and engineers are well qualified to identify sources of odors, determine concentrations of airborne and/or surface contaminants, interview building occupants to evaluate exposure potentials and episode trends, and perform ventilation system analyses, as well as conduct literature search and evaluate the potential for disease clusters. Typically during indoor air quality surveys, we interview building occupants to evaluate exposure potentials and episode trends, we inspect HVAC systems, and we collect air samples as deemed appropriate to determine actual exposures to various chemical substances such as fibrous and non-fibrous dusts, carbon dioxide, formaldehyde, carbon monoxide, volatile organic compounds, pesticides, ozone, asbestos, and ioaerosols (fungi and bacteria). We also have the capability to assess surface microbial growth contamination and to assess the presence of dust mites and other insects, pollens, animal dander, or other potential allergens; as well as verify pest infestation.
Comprehensive reports are prepared which include background information; observations of operations and work practices; descriptions of environmental conditions and ventilation system design; sampling and analytical methods; data interpretation; explanations of applicable U.S. or foreign non-industrial exposure standards; conclusions; and recommendations concerning regulatory compliance, engineering controls, and employee training. All data are evaluated in light of current OSHA or foreign permissible exposure limits, TLVs, or other exposure guidelines such as the American Society of Heating, Refrigerating, and Air-Conditioning Engineers, Inc. (ASHRAE) recommendations for indoor environments or, for informational purposes, World Health Organization or foreign standards established for non-occupational exposures.
