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(s): May 23, 24, 25, and 26, 2022
Building Maintenance reported a leak associated with the fire suppression system on May 23.
The Office of the Environment arrived onsite on the 23rd. A contractor was onsite correcting the leak however, the leak was still active (leaking water being collected in a container).
Water had entered Room 54 and impacted wood casework and carpeting. Building Maintenance had already drilled holes in casework and placed fans on the impacted carpeted areas to facilitate drying.
The carpet had already been extracted by Custodial Services.
The Office of the Environment identified additional casework (at entry door) that was impacted and removed the cove base and drilled additional holes.
Additionally, an area rug was impacted and left in place. The Office of the Environment placed the area rug on chairs to dry the carpet underneath and to facilitate drying the underside of the area rug.
Areas were re-assessed on the 24th, 25th, and 26th. Approximately 2 linear feet of casework was identified to have elevated moisture. Additionally, a one square foot area of carpet was also identified with elevated moisture. On the 26th, the casework was determined to be sufficiently dry. Cove base was to be re-installed following the long weekend in order to provide extra drying time.
A small portion of the carpet was still showing elevated signs of moisture, however it was dry to the touch. The flooring specialist (Building Maintenance) also assessed the area with no concerns identified. The moisture meter reading is expected to be an anomaly (possible contact with a metal object under the floor). No further action appears warranted.
The following response actions are intended to prevent microbial growth.
