Date of Assessment: August 14, 2020.
On August 12, 2020, the work order 164006 was generated by the school regarding a water leak.
On August 14, 2020, the Office of Environment arrived to asses the water leak. After speaking with Day Building Supervisor, it was learned the work order had the wrong room location (C35) when Building Services initially responded (they could not locate problem). The leak occurred in the custodial office and impacted the drywall wall shared between the custodial office and a custodial closet (C125). The leak was condensate from the custodial office's fan coil unit (FCU).
Office of Environment notified Building Services the drywall (~1.5 linear foot) to the right of the FCU was moist and to peel back the vinyl base, drill holes in base, and place carpet blowers to force air onto/into impacted drywall for three days..
On August 18, 2020, Building Services removed the carpet blowers and repaired the vinyl base.
The above actions were to prevent microbial growth as a result of the water incident.
Building Services dried and repaired drywall via work order 164006.
Building Services is to review the FCU's condensate pan and drain line to prevent recurring incidents.
