Teacher working conditions are student learning conditions. 🍎 On #WorldTeachersDay, UNESCO reminds us that protecting the profession means protecting educators. In Ontario, that must include basic workplace safety of clean indoor air free of pollutants and airborne infectious diseases. #OntEd #IAQ

Because young children’s lungs are still developing and smoke can affect anyone’s health even at low levels, governments must take responsibility to ensure that schools and school buses (places where people are required to be!) always have clean indoor air to breathe.

There are NO downsides to improving the quality of air in the spaces in which our kids and their educators spend the most time. Even the cost makes itself up in reducing replacement staffing costs, bettering education, decreasing healthcare burden, etc.

CO2 and PM2.5 monitoring helps us understand the quality of the air we're exposed to indoors and outdoors. They also inform us about the strategies to mitigate exposure, such as wearing an N95, running an air purifier, closing windows and doors, and using MERV13+ furnace filters. #cleantheair

Wildfire season means the tools we have to manage indoor air quality are more important than ever! People are driven into tightly sealed indoor settings, which can lead to increased CO2 levels and illness spread. Outside smoke can still find its way in, impacting our lungs and hearts. #cleantheair

This is the 2nd article I’ve seen that cites illness as the number 1 cause of student absences. No one is suggesting any solutions to the biggest problem, why not? We know improving air quality can reduce many illnesses and improve concentration. Schools already have air filters. What’s the holdup?

If health-related reasons (e.g., respiratory illness, mental health issues, disability) are even partly responsible for this rather dramatic increase in absences, making students' grades contingent on being present could very well make matters worse.
