was not operating during the assessment. In addition, exhaust vents in restroom/shower areas in the girls’ locker room gym office were not operating. Exhaust vents in locker rooms and restroom/shower areas should be activated/repaired to remove odors, excess heat and moisture. Strong tire/rubber odors were detected in the gym equipment room, which was not equipped with any means of exhaust ventilation. Exhaust ventilation for classrooms in the original portion of the building is provided by floor level cubby holes. Air is drawn into these cubby holes and ducted to rooftop motors. The design of these exhausts makes them prone to blockage by classroom items (Picture 4). Exhaust ventilation in the remainder of the building is provided by wall-mounted vents, which were also found obstructed in several areas at the time of the assessment (Picture 5). Both wall and cubby hole exhausts were found not drawing or weakly drawing air in a number of areas (Table 1). In some rooms exhaust vents are located near hallway doors, which reportedly are generally left open. With the hallway doors open, the exhaust vent will tend to draw air from the hallway into the classroom, instead of drawing stale air the classroom. Therefore it is recommended that from classroom doors remain shut while exhaust vents are operating. To maximize air exchange, the MDPH recommends that both supply and exhaust ventilation operate continuously during periods of occupancy. In to have proper ventilation with a mechanical supply and exhaust system, the systems must be balanced to provide an adequate amount of fresh air to the interior of a room while removing stale air from the room. It is recommended that heating, ventilating and air conditioning (HVAC) systems be re-balanced every five years to ensure adequate air systems function (SMACNA, 1994). The date of the last balancing of these systems was not available at the time of assessment.
