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: December 27 and 30, 2022 and January 1 and 3, 2023
HCPSS Facilities initially responded to the incident by isolating the source of the leak, extracting water, and start the drying process.
On December 27, the Office of Environment performed an assessment (visual and moisture detection meters) to assess the drying process. The media darkroom and closet C-225 within 225 were additional areas that needed to be included in the drying process.
The materials impacted included the base of drywalls and wood casework. Building Services removed the cove base from the impacted items, drilled holes within, and placed air movers to direct air onto and into the base of the items to facilitate drying.
On December 30, the Office of Environment determined areas were not completely dry and informed Building Maintenance to continue the drying process.
On January 1, the Office of Environment determined all areas were dry with exception to the base of drywall in room 225-A and a portion of the wall in 225 near C-225. Building Maintenance was instructed to remove one side of the drywall (2' from floor) and the fiberglass insulation within the wall cavity then dry the remaining side of the drywall provided no visible mold growth was present.
On January 3, the remaining drywall was assessed and determined to be dry. Building Maintenance was informed the areas were ready for repairs and finishing work.
The above actions are meant to prevent the potential for microbial growth.
