If you are in California, you know that with wildfires, you have to offer your employees masks if the air particulate levels get above 150. And not just any mask, and N-95.
It looks like CalOSHA has bent on that a bit. So here are two guides. 1) who has N-95 masks (although I have found this to be sketchy), plus FINALLY 2) how to get other masks that still ‘count.’ This is a recent change – 9/28/2020.
Also – you can monitor air quality through many different websites, but I find Air Visual works well in looking at large areas on a map, or zooming in.
