- 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: February 26, 2020
A strong musty odor was detected upon entering the space. The odor seemed to be strongest in the front right corner of the classroom.
This odor apparently had migrated to the adjoining classroom (66) over time.
No elevated moisture was detected in or on the casework (cubbies and book-bag hangers) in the corner of the room.
No thermal anomalies indicative of moisture intrusion were identified.
No concerns were noted above the drop-ceiling in Room 65 or the adjoining hallways.
Several books were located on-top of the shelf in the corner of the room. One of the dividers (dividing the books) appeared to have water marks, however no other books or materials showed any indication of water staining or moisture.
One of the cubbies contained a small plastic bag. The plastic bag was opened and contained wet clothes and a strong musty odor. The bag was removed from the room by the teacher and the odor dissipated.
