|
| The National Institute for Occupation Safety and Health (NIOSH) found that up to 52 percent of IAQ problems results from insufficient or ineffective ventilation. |
|
| MSES Industrial Hygienists understand that IAQ problems are difficult to diagnose and solve because of the many types of contaminants or building stressors that can cause problems. In fact, the cumulative effect of many stressors (chemical, biological and physical) is often the most difficult to identify. MSES IAQ diagnostics are conducted in accordance with ASHRAE 62-1989, Ventilation for Acceptable Indoor Quality. |
|
| Water damage to building materials can significantly increase the growth of toxic molds such as Stachybotrys, Aspergillus, and Cladosporium. Mechanical ventilation equipment can also contribute to indoor air contamination and be a source of dust, mold, bacteria and viruses. Improperly located air intake ducts can bring outside pollutants into the indoor environment, and building materials are a source of many different volatile organic compounds (VOCs) and formaldehyde that add contaminants to the indoor air. |
