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: November 10, 2025
The Office of the Environment observed less than two linear feet of stained pipe insulation. The pipe insulation was cleaned out of an abundance of caution with a disinfectant however, staining was still present after cleaning.
No visible evidence of an active leak was observed in the vicinity of the safety shower. No visible evidence of mold growth or staining was observed on the pipe insulation above the ceiling tile.
A root cause was not identified, however the staining/discoloration may have occurred due to a historic leak or humidity concerns identified during the Summer of 2025 (see IEQ Concern: CXMHMS202500035F for additional detail).
Building Maintenance will replace the pipe insulation above the safety shower.
