Findings

Date(s) of Assessment:  November 21, 2018

The Office of the Environment instructed the school to clean or discard the instrument cases when the concern was originally submitted.

Instrument cases (especially older ones) are susceptible to relative humidity mold growth in the summer time.

In addition to room 006, Rooms 004 (art) and 008 (choral) were inspected for relative humidity mold related to this past summer weather pattern of extended and excessive moist (air) weather.  The rooms are served by the same ventilation unit.

Mold growth was observed on the casing of a speaker within room 006.

Suspect mold growth was observed on surfaces of the art tables and a chair strap.

Corrective Actions
November 21st, 2018
