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: December 30, 2020
The incident occurred because the main utilities had been shut-down for the building to repair a water main break. A slop sink was apparently on when the water main was shut-off and not turned to the off position.
Once water was restored, the slop sink began running water (during off-hours) and overflowed, impacting the main hallway (non-porous surfaces) and the health suite.
Building Maintenance (Plumbing) discovered the issue while assessing the building after water had been restored.
Materials within the Health Suite impacted by the leak included wooden casework and drywall.
Impacted drywall and fiberglass insulation was removed.
The cove based was removed from the wooden casework and holes drilled to facilitate drying.
The Office of the Environment inspected the site on December 30, 2020. The impacted materials were determined to be dry. Building Maintenance was contacted to inform them that the space was ready for new materials.
The response actions above are conducted to prevent microbial growth.
