Section 18 AAC 30.330 - Heating(a) Classrooms must be kept at a minimum temperature of 65 degrees F. at desktop level.(b) The heating system in a school must be installed in a manner which prevents drafts from being directed on students.(c) Heat sources in a school must be shielded in a manner that prevents burn injury. The shield must be far enough from the heat source to prevent it from smoldering or burning.(d) Heating units and other devices which employ a flame must be vented to the outside. Vents or stacks leading from a heating unit must be airtight at all joints so that fumes, smoke, or unburned gases cannot pass from the device, vent, or stack into the school.Eff. 4/18/82, Register 82
