#ventilation

"Tiny particles in the air can cause a range of short-term and chronic health issues, experts say. Wildfire smoke can settle over cities for days — like the recent blanket over parts of the U.S. from burning fires in Canada, which has created hazardous air for millions of people across multiple states. Health officials advise people to stay indoors — and to take steps to keep the air in your home clean." https://apnews.com/article/wildfires-smoke-filters-e39f285bec1eccfdb0fbc33b753a987a #PublicHealth #AirQuality #wildfires #smoke #ventilation

In Belgium, #workplace #heat thresholds are explicit:

• 29°C for #office work
• 26°C for moderate work (such as shelf stacking)
• 22°C for heavy work (such as #warehousing, #construction)
• 18°C for very heavy work (such as #roadwork)

When these temperatures are exceeded, #Belgian #employers must take measures such as #cooling, #ventilation, extra breaks and providing drinks

imagine if i cancelled the remainder of every university class i taught once the CO2 level in the classroom rose to over 1000 ppm, on the basis of that study referred to in the boost. imagine if professors banded together, equipped ourselves with CO2 sensors, and we all did cancelled class time spent above 1000 ppm. then we would get better ventilation on campus. and the students would get better learning experiences!! #CovidIsNotOver #Ventilation #MaskUpIndoors
