Masks are no longer required per State regulations but are highly recommended by the Palo Alto Adult School.
Teachers with underlying medical conditions or are immunocompromised may request masking at their discretion.
Social distancing is no longer required.
We have worked with mechanical engineers, heating, ventilation, and air conditioning (HVAC) design professionals, and mechanical contractors in order to evaluate our ventilation systems in regards to the ASHRAE guidance.
We have maximized air filtration for HVAC systems by using filters with a minimum efficiency reporting value (MERV) of at least 13 and made other modifications to increase the quantity of outside air and ventilation in classrooms, offices and other spaces.
Portable high-efficiency air cleaners have also been deployed where needed.
Engineering systems are in place for when the amount of outside air needs to be minimized due to other hazards, such as heat and wildfire smoke.
