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 of Assessment: August 11 and 14, 2023
Custodial Staff requested the Office of the Environment assess suspect mold growth on the carpet in Room 406.
Approximately two square feet of mold growth was observed on the carpet.
It was reported that Custodial staff had cleaned the carpet using wet methods on Friday, August 11, 2023. It was reported that floor fans were not placed in the area after cleaning.
The mold growth likely occurred due to lack of Heating Ventilation and Air Conditioning (HVAC) over the weekend, closed room conditions, and a lack of airflow.
Custodial staff recleaned impacted carpet with wet methods and placed fans within the classroom to dry out the carpet. The Office of the Environment re-assessed after the cleaning. No visible mold growth was observed. The carpet was also probed with a moisture meter. No elevated moisture was detected.
It is recommended to use floor fans in the future. Custodial Services can also request ventilation to assist with drying efforts.
