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: November 21, 2018
The Office of the Environment instructed the school to clean or discard the instrument cases when the concern was originally submitted.
Instrument cases (especially older ones) are susceptible to relative humidity mold growth in the summer time.
In addition to room 006, Rooms 004 (art) and 008 (choral) were inspected for relative humidity mold related to this past summer weather pattern of extended and excessive moist (air) weather. The rooms are served by the same ventilation unit.
Mold growth was observed on the casing of a speaker within room 006.
Suspect mold growth was observed on surfaces of the art tables and a chair strap.
The impacted surfaces were cleaned / disinfected at the time of the finding.
These rooms consist of one ventilation zone and will be monitored as necessary during the summer of 2019 to ensure the ventilation system is operating as designed.
