Yet another reason how masks are causing HARM. Schools should NOT be mandating these -
# OSHA guidelines recommend CO2 levels under 1100ppb indoors.
# We begin to experience Illness at 2000ppb.
# Within seconds of N95 mask, the reading hits 10,000ppb and can not register anymore.
# Within seconds of a surgical mask, levels are above 8,000ppb.
# Within seconds of a bandana cloth mask, levels are above 9,000ppb.
# Even with a face shield, levels approach 1800ppb.
# Not only do masks become Petri dishes of bacteria, viruses and mold, they don’t prevent viral transmission, and they cause CO2 toxicity.
