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)
Findings

Dates of Assessment:  September 2 and 8, 2020.

HCPSS Project Manager contacted the Office of Environment regarding the incident.  The following items were wet / impacted.  

  • carpet (~10' x 10' area)
  • several ceiling tiles (discarded)
  • base of drywall of shared walls with the hallways and storage / electrical closet within the hallway.
  • drywall above the drop ceiling where pipe was disconnected.

Office of Environment directed the HCPSS Project Manager and roofing contractor of the materials impacted and how to dry those not needing to be discarded.  The roofing contractor had their own drying equipment.   Dehumidifiers and carpet blowers were utilized to dry impacted materials.  Holes were made within impacted drywall to force air into the drywall cavity. The equipment was to run until the Office of Environment reassessed the impacted materials .

On September 8, 2020, the Office of Environment determined impacted materials were dry and equipment could be removed.

This response is meant to prevent microbial growth from forming as a result of the incident.
