Note: The Office of the Environment has recently transitioned to a new Online IEQ platform (as of August 2018). The new platform does not allow the back-dating of IEQ concerns. This concern is inappropriately dated September 4, 2018. The concern should be dated May 16, 2018.
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)
The suspect mold growth had been cleaned prior to the Office of the Environment arriving.
A thermal infrared screening within the freezer indicated that the pipe insulation associated with the cooling unit had failed (wet and deteriorating).
The condensation drain for the cooling unit had been caulked over, likely backing up condensation into the unit.
It was reported that the freezers compressor was not working properly.
Under work Order #71790, the caulk was removed from the drain allowing condensation to flow out of the system.
The freezers deteriorated pipe insulation was replaced by a Food Services contractor.
The freezers compressor was replaced by a Food Services contractor.
