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)
Date(s) of Assessment: January 11 and 23, 2019
No mold growth was observed within the room.
Odors associated with cooking were observed within the room (FACS Room) and in the nearby hallways in the vicinity of the room.
The room was screened with a thermal infrared camera. No thermal anomalies indicative of moisture intrusion were observed.
The drier vent appeared properly connected and properly vented out of the building.
A stained ceiling tile was observed. No active leak was observed in the vicinity of the stained ceiling tile.
The supply diffusers were dirty.
The condition above the drop-ceiling was acceptable.
The temperature was acceptable.
Relative humidity was "low" (24.9%, typical of the winter season). Low humidity could play a role in the health symptoms described, however HCPSS does not add humidity (humidifying can introduce other clinical environmental concerns such as humidifier fever).
There were no chemicals in the area, only cooking supplies.
The Air Handling Unit (AHU) that services the space was assessed. The unit was in good condition, however the outside air dampers were closed.
While on the roof, the penthouse was inspected. The penthouse contained a former AHU that is no longer in use. The duct work from the unit has been sealed off, eliminating the former penthouse as a concern.
Custodial Services cleaned the supply diffusers.
Building Services (HVAC) identified issues with the wiring/controls of the outside air dampers for RTU-1 and RTU-7. Both were repaired.
Custodial Services is to change the stained ceiling tile. If a leak persist, submit a working for Building Services to assess and address the cause of the leak.
