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: October 24, 2024
The Office of the Environment spoke with custodial staff regarding the IEQ Concern.
Staff member indicated that area of suspect mold was identified underneath an area rug under the handwashing sink outside the bathroom (outside room C08). Staff member indicated that this was the first time that suspect mold was observed. Staff member recalled excess moisture being underneath the carpet. It was reported that students like to "play" at the sink area.
No visible mold was observed at the time of assessment.
Loose floor tiles were observed around handwashing sink underneath the area rug.
The source of suspect mold growth was likely from excess water from handwashing sink being trapped underneath the rug.
Loose and unsecure floor tiles to be re-adhered.
The below suggestions can be followed to prevent future fungal growth while maintaining occupant safety (slips/trips/falls):
- Increase supervision of students during high volume times of handwashing reduce to incidental spills/splashing.
- Replace area rug with a rubber mat with holes. This will provide traction and additional air flow for drying.
