With the exception of Oak Terrace Elementary School, buildings in North Shore School District 112 are not fully air-conditioned During extreme warm weather, district staff take precautions to ensure that children are adequately hydrated and stay as comfortable as possible. Below are guidelines that district staff follow during warm-weather conditions:
- Ensure that drinking water is readily available and that students are well hydrated.
- Remind students and staff to wear lightweight, loose-fitting cotton clothing.
- Prevent students from overexerting themselves.
- Keep children indoors or in shady areas during the hottest parts of the day.
- Avoid taking children outdoors when temperatures are very high.
- Take all necessary steps to ensure keeping classroom temperatures comfortable.
- Keep windows and doors open, and have at least one fan running.
- Avoid use of heat-generating equipment like Promethean boards, projection cameras, etc.
- Monitor temperature and humidity levels throughout the day in rooms expected to have high temperatures, and calculate the effective temperature (ET).
- Move students to cooler areas of the building in rooms where ET exceeds 85 and there are more than 2 hours remaining in the school day.
The district refers to the NOAA National Weather Service’s Heat Index Chart, which provides information about the likelihood of heat disorders due to prolonged exposure to high temperatures and humidity. If the forecasts call for the outdoor heat index to be at the “danger” level or higher, this triggers a decision to either shorten the school day, or close school. When the outdoor heat index is at this level, our indoor classrooms generally have even higher heat indexes, at what the National Weather Service has determined is the danger level. The Illinois School Code allows for the use of interrupted school days or emergency closing days for adverse weather conditions.
