Tips for schools and childcare settings

General tips

When occupied, keep windows open a few inches (at a minimum two front and two rear windows) to provide adequate ventilation (as long as it does not create a safety or health hazard).
Opening windows is beneficial for daily bus commutes as well as during transportation of school groups to different events (sports, field trips, etc.).
Do not fog/mist the bus with disinfectant, as this can lead to poor air quality.
Leave windows open to air out the bus after use and clean when visibly dirty.

Refer to Washington State Department of Health's K-12 Schools and Child Care Guidance for current requirements and guidance to mitigate COVID-19 transmission in schools and child care settings. It's important that you follow masking and ventilation guidelines for possible COVID-19 cases.
When community transmission levels are high or outbreaks are occurring in a school, eat meals outdoors when feasible. Consider providing distance between each person in dining and snacking areas. Staggering mealtimes may help accommodate physical distancing.
Note: strategies recommended for reducing COVID-19 will also reduce the spread of other airborne illnesses and thus student and staff absences.
