“OSHA requires a minimum reading of 19.5 oxygen for a safe working environment.”
Where is. this requirement?
Paragraph (d)(2)(iii) of the Respiratory Protection Standard considers any atmosphere with an oxygen level below 19.5 percent to be oxygen-deficient and immediately dangerous to life or health. To ensure that employees have a reliable source of air with an oxygen content of at least 19.5 percent, paragraphs (d)(2)(i)(A) and (d)(2)(i)(B) of the Respiratory Protection Standard require employers working under oxygen-deficient conditions to provide their employees with a self-contained breathing apparatus or a combination full-facepiece pressure-demand supplied-air respirator with auxiliary self-contained air supply. In the preamble to the final Respiratory Protection Standard, OSHA discussed extensively its rationale for requiring that employees breathe air consisting of at least 19.5 percent oxygen. The following excerpt, taken from the preamble, explains the basis for this requirement:
Human beings must breathe oxygen . . . to survive, and begin to suffer adverse health effects when the oxygen level of their breathing air drops below [19.5 percent oxygen]. Below 19.5 percent oxygen . . . , air is considered oxygen-deficient. At concentrations of 16 to 19.5 percent, workers engaged in any form of exertion can rapidly become symptomatic as their tissues fail to obtain the oxygen necessary to function properly (Rom, W., Environmental and Occupational Medicine, 2nd ed.; Little, Brown; Boston, 1992). Increased breathing rates, accelerated heartbeat, and impaired thinking or coordination occur more quickly in an oxygen-deficient environment. Even a momentary loss of coordination may be devastating to a worker if it occurs while the worker is performing a potentially dangerous activity, such as climbing a ladder. Concentrations of 12 to 16 percent oxygen cause tachypnea (increased breathing rates), tachycardia (accelerated heartbeat), and impaired attention, thinking, and coordination (e.g., Ex. 25-4), even in people who are resting.
At oxygen levels of 10 to 14 percent, faulty judgment, intermittent respiration, and exhaustion can be expected even with minimal exertion (Exs. 25-4 and 150). Breathing air containing 6 to 10 percent oxygen results in nausea, vomiting, lethargic movements, and perhaps unconsciousness. Breathing air containing less than 6 percent oxygen produces convulsions, then apnea (cessation of breathing), followed by cardiac standstill. These symptoms occur immediately. Even if a worker survives the hypoxic insult, organs may show evidence of hypoxic damage, which may be irreversible (Exs. 25-4 and 150; also reported in Rom, W. [see reference in previous paragraph]).
I was on a sub on mission, we could not surface, we lost 1 of 2 o2 generators and 1 of 2 co2 cow scrubbers.
We were burning o2 candles, it was not a good place.
So amazing! For 150 years tens of millions have worn masks without problems, so glad they found there actually are problems. Now, let’s go spread the virus and really show them!
And there you go.
post 22 BTW.
OSHA requires a minimum reading of 19.5 oxygen for a safe working environment.”
Where is. this requirement?
The Occupational Safety and Health Administration, OSHA, determined the optimal range of oxygen in the air for humans runs between 19.5 and 23.5 percent.

Now, please provide link/info that proves any of the sentence you posted and labeled as WRONG!
TIA.
An advocate for tyranny?
Oxygen BTTT
That is a letter, not a rule. Show me the rule.
God bless you. That is a place I would not want to be. I was a kid when the Thresher incident happen. Couldn’t get it out of my head for weeks.
If he stuck the tube down into his trachea, he would get the same results with no mask.
“optimal range “
Going outside the optimal range is not unsafe.
I take 60mg Zinc, 10,000 units of D3 and 1,000 units of C, daily, along with 23 other Rx and OTC pills.
i have breathing problems too and wear my mask UNDER my nose and have had no pushback here in colorado ...
“Paragraph (d)(2)(iii) of the Respiratory Protection Standard”
Link please.
I just checked all my hundreds of test results on the Wellspan Portal, going back to 2017, and see no Vit D3 level, specifically. Is there an abbreviation I should be looking for, instead of D3?
Since you are too lazy to look it up here is a start.
