All common, union free, central, central high schools, city school districts and boards of cooperative educational services shall develop a policy for ensuring the health and safety of students, faculty, and other employees, on extreme heat condition days. For the purpose of this section, extreme heat condition days shall be defined as days when the occupiable educational and support services spaces are found to be eighty-two degrees or greater Fahrenheit. For the purpose of this section, support services spaces shall not include kitchen areas used in the preparation of food for consumption by students. For the purpose of this section, room temperature shall be measured at a shaded location, three feet above the floor near the center of the room. Schools shall be required to take action to relieve heat-related discomfort when the occupied space temperature reaches eighty-two degrees Fahrenheit. These actions may include, but are not limited to, turning off the overhead lights, pulling down shades or blinds, turning on fans, opening classroom doors and windows to increase circulation, turning off unused electronics that produce heat, and providing water breaks. Educational and support services spaces cannot be occupied if room temperature reaches eighty-eight degrees Fahrenheit.
