If trends are observed, a systematic evaluation of the indoor environment will be undertaken. This evaluation will consist of collecting indoor air samples for biological or chemical analyses. Biological analyses requires an allergic profile from affected individuals prior to sample collection. As of the date of this draft, OSHA nor the EPA has developed standards which describe acceptable levels of airborne bioaerosols. In lieu of this deficiency, CSUF considers environments in which indoor biological levels greater than outdoor levels as unhealthy.
Chemical analyses of indoor air requires a less invasive approach.
If the source cannot be removed, efforts to contain or isolate the source will be undertaken. In addition to biological and chemical assessments, physical assessments will also be conducted. Monitoring of temperature and humidity will round out the systemic approach to solving an IAQ issue. This range is dependent on dew point temperature and season. Dry or humid air may respectively lead to upper respiratory irritation and microbiological growth.
