This is Insanity!! Face masks don’t do Jack,and are probably worse for you and the spread of the benign chicom flu
Hmmmmm.. Do the home made cotton/filter/cotton material masks induce nausea, light headness, low oxygenation of blood, increase of CO2 inhalation??? Are these conditions placing young children, the elderly at risk???Seems there are more and more anecdotal stories regarding these conditions.
And just how do they intend to enforce this ridiculous edict
I’m an indoor air quality consultant so I get to read and study some obscure stuff.
Please see below, this was a USA, OSHA document from 2009
Very small excerpt from a document entitled
PANDEMIC INFLUENZA PREPAREDNESS AND RESPONSE GUIDANCE FOR HEALTHCARE WORKERS AND HEALTHCARE EMPLOYERS. Occupational Safety and Health Administration 2009
“When personal protective equipment is necessary to protect against droplet transmission of infectious agents, employees must place a barrier between the source of the droplet (e.g., a sneeze) and their mucosal surfaces. Such protection could include a surgical mask to cover the mouth and nose and safety glasses to cover the eyes. Recent studies show that aerosol penetration through a surgical mask is highly dependent on particle size, mask construction, and breathing flow rate.
One study showed that penetration rates for submicron particles could be as high as 80 percent for surgical masks.36
Even relatively unconventional uses (e.g., the wearing of multiple surgical masks) have been shown to be less protective than NIOSH-certified respirators. For example, research has shown that the use of up to five surgical masks worn by volun teers results in particle reduction of only 63 percent for one mask, 74 percent for two masks, 78 percent for three masks, and 82 percent for five masks, compared with a recommended reduction of at least 95 percent for properly fitted N95 respirators.37”
