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 Assessments: November 24 and December 1, 2020
A plumbing leak occurred in association with the sink in Room C120. The leak had already been corrected when the Office of the Environment arrived. Additionally, the cove base had been removed in impacted areas and fans were already in place to facilitate drying.
Room C120 - A moisture meter was used to determine the extent of the impact. The carpet and drywall were dry upon arrival. Residual staining was visible on the carpet. A faint odor likely associated with wet carpet was also noted. Custodial Services was in route to perform additional cleaning on the carpet.
Room C122 - A moisture meter was used to determine the extent of the impact. The carpet and drywall were dry upon arrival. Additionally, two linear feet of casework had also been impacted. The cove base was removed and a hole drilled to facilitate drying.
Fans were left in place to re-dry the carpet after custodial cleaned and to continue to dry the casework.
The areas were re-checked on December 1st. No elevated moisture was detected in the drywall or casework. The residual staining and faint carpet-like odor in C120 were no longer present.
The response actions above are intended to prevent microbial growth.
