(b) All rooms, areas, and equipment, from which contaminated aerosols, obnoxious odors, or noxious fumes or vapor may originate shall be effectively vented to the outside air.

(c) Windows, including louvers opened from the bottom, which cause direct currents of air on students nearby, shall be provided with window ventilators or deflectors.
