Ventilation Studies

SES staff can assist employers in assuring safe workplaces by performing industrial hygiene evaluations, which may include review of workplace practices, ventilation studies and personnel monitoring.

SES staff routinely perform investigations to determine causes of poor indoor air quality and make recommendations on how to alleviate problems.  Typical parameters monitored include temperature, relative humidity, carbon dioxide and carbon monoxide.  Workplace evaluations may also include sampling for human and commensal bacteria, thermophilic bacteria, fungi, and chemical compounds which may be indicative of an indoor air quality problem.
