Room D13 had an aroma resembling a rubber floor / new product. A source could not be identified. An observation, no action necessary. Room D16 had a wicker basket on top of the supply diffuser of the ventilation unit located along the exterior. Besides partially obstructing air flow, during cooling, the basket material could become damp and form mold growth. School administration is to remind staff not to place items on top of the unit's air supply diffuser.

The exposed side of the supply air diffusers have dust accumulation and/or dirt smears in room D24. School custodial staff is to clean diffusers not leaving any visible residue.

Condition

No
An air freshener aroma was detected in room B59. The air freshener was not observed. School administration is to remind staff air fresheners of any kind are not permitted and is to be removed if present. Air fresheners may mask an odor of concern or be an irritant to others. Room D16 had a large stuffed bear on a file cabinet and several other stuffed animals along the windows. School administration is to determine if these are required for educational instruction and if not have them removed or ensure they are vacuumed periodically.
No stained or damage ceiling tiles
No
Water stained ceiling tiles were observed in rooms A71 and C18 (near VAV marking on ceiling grid). If not already being addressed, school custodial staff is to submit a work order for Building Services to evaluate, correct leak, and replace ceiling tile.
No visible mold present (walls, cabinets, under sinks, behind posters)
No
The window sill in portable 191 was discolored / stained (not mold growth) from a past water event (rained evening prior to inspection and no moisture detected). Work order 206722.
Relative Humidity
Not above 70%
No
The dehumidifiers present in portables 190 and 191 were not turned on at the time of the inspection (inspector turned on at the time of the finding). The relative humidity in portable 190 was at 68% and portable 191 was 72%. The dehumidifiers have been temporarily provided to portable classrooms to prevent possible mold growth due to extended elevated interior relative humidity (70%+) from the ventilation unit's fan being set to "on" instead of "auto" as a COVID precaution (ensures constant introduction of outdoor air).
