IEQ Investigation Process

Identify deficiencies that may impact IEQ and/or sources of odor concerns. Typically includes the following depending on the nature of concern, but not limited to:

  • interview/questionnaire of concern individual(s)
  • inspection above drop ceiling (condition of roof deck, pipe insulation, return air plenum)
  • inspection of ventilation system (operation of variable air volume box and outdoor air dampers, check controls, measurements of carbon dioxide, temperature and relative humidity, sources near outdoor air intake, measure return and supply air volume, cleanliness of coils, liner and condensate pan)
  • inspection of exterior
  • inspection below drop ceiling (housekeeping, sink and floor drain traps, signs of past and present moisture concern via visual and/or moisture meter, mold growth, ensure connection of current and capping of abandoned sanitary vents, odorizers, excessive plants and fabric items, identify potential pathways, and measure volatile organic compounds, carbon monoxide, and lighting)
Findings

Water staining and decaying of the wood cabinet was evident.

Several locations of the cabinet were probed with a moisture meter (wood setting). The flooring of the cabinet contained elevated moisture.

The drain-trap associated with the sink above the cabinet was corroded.

Visible mold was observed within the cabinet.

A thin layer of wood was installed on the cabinet floor. A portion of this layer was removed. Mold growth was also observed under this material. 

In general, housekeeping within the cabinet was poor.

No apparent rodent activity was observed.

Corrective Actions
August 29th, 2018

The Office of the Environment cleaned/disinfected accessible materials impacted by mold growth.

August 31st, 2018

Building Services (Plumbing) replaced the sink trap within the cabinet. 

October 19th, 2018

Building Services (Carpentry) plans to replace impacted cabinetry on October 19, 2018. The cabinet is not accessible to students. The Office of the Environment recommends the cabinet remain closed until it is repaired. Repairing the cabinetry and apparent leak will likely reduce the reported rodent activity.
