Video of a man using an air quality monitor to prove that wearing masks creates unsafe work conditions is going viral as the national debate about masks intensifies in the face of rising coronavirus cases.
“Lotta people are saying they’re getting headaches and stuff from wearing a mask that they’re requiring us to wear pretty much everywhere we go,” the man says. “And I’m gonna test oxygen level under a mask using an OSHA-approved air quality monitor that tests for oxygen levels, hazardous gas levels, LEL, CO, and H3H2, stuff like that.”
“OSHA requires 19.5% oxygen to work in a space. Look it up. Normal oxygen level is anywhere from 20 to 21.”
He then demonstrates the normal oxygen level without wearing a mask by placing the reading tube near his uncovered mouth, which gave a normal reading.
“I’ve got 20.5. That is the oxygen level without the mask,” he says.
