Important! What kind of mask are you wearing? "If work requires you to wear a mask, OSHA requires that your employer verifies you are receiving a minimum of 19.5% oxygen level by law!" Here’s more mask info from a poster “Jim” in response to an article re: face masks: “ I don’t really know WHY OSHA hasn’t come forward and stopped the nonsense BUT wanna cover kinds of masks: • N95 masks and masks with exhale ports • Surgical masks • Filter or cloth masks Okay so upon further inspection OSHA says some masks are okay and not okay in certain situations. If you’re working with fumes and aerosol chemicals and you give your employees the wrong masks and they get sick you can be sued. • N95 masks: are designed for CONTAMINATED environments. That means when you exhale through N95 the design is that you are exhaling into contamination. The exhale from N95 masks are vented to breathe straight out without filtration. They don’t filter the air on the way out. They don’t need to. Conc
