The metal siding (end without HVAC unit) has a screw missing allowing an opening for inadvertent rain to enter (the interior drywall was dry per moisture meter). Work order 232320. The condition of the roof on portables 162 (numerous rust spots) and 247 (possible tare in rubber membrane) need to be reviewed and addressed (monitored and/or repaired). Work order 232319.
Classrooms (Assess 2 to 3 per HVAC System Zone)
Check OK Comments
Condition
Room is free of dust and clutter
No
Visible dust accumulation was observed on shelving of casework in room 39. Custodial staff is to clean now and then per their cleaning schedule. Room 42 has excessive fabric items that can collect allergens overtime and when disturbed will release potential allergens, especially if not properly maintained by teaching staff (custodial not responsible). Presently, the materials appear clean. The additional items may also fall under the rule where the school is to apply spray fire retardant on these coverings. A throw rug is on the floor tile near the sink. This throw rug bunches and moves when stepped on presenting a fall hazard. School administration is to assess if these additional items (see photos in the email cover letter to this report) offer any educational value or is meant to enhance student(s) behavior or attentiveness. If not, consider reducing the amount of these additional items. Although not as excessive as room 42, rooms 1C (fabric toys and not wipeable bean bag) and 2B (stuffed animals) have questionable amount of fabric items that need to be addressed by school administration. Food was not adequately protected from pests / rodents in rooms 1C and 2B. School administration is to inform staff to place food items in sealable container.
No stained or damage ceiling tiles
No
Water stained ceiling tile observed in cafeteria (at exit door). If not already being addressed, custodial staff is to submit a work order to Building Maintenance to evaluate and correct the source.
