A great new product idea would be an airline travel hood. It would attach a hose to the overhead air vent and feed a plastic bag that the passenger would then place over their head and secure around their neck. It would have some air holes at the bottom to allow airflow which would be covered by a filter to prevent droplets from escaping.
Of course if the pilot cycles the power the air duct would shut down and everyone would suffocate but until then it would be totally safe.

Does not safe < 19.5% is unsafe.
“Since you are too lazy to look it up here is a start.”
Nope. Just fun to see people pull bs out of their rear.
For 150 years masks were worn in operating rooms and where procedures were performed to keep from spreading bacteria to open wounds. Masks at best filter to 5 microns and viruses are 150 time smaller. In 1918-19, they wore masks and the virus still spread quickly and widely. If you spent time in the hospital before the scamdemic, the nurses, doctors, and staff didn’t wear masks nor did the visitors. If hospitals deal with an active and dangerous viral infection, you are isolated in a sealed laminar flow area and the staff wear hazmat suits and decontaminate as soon as the leave. Even that doesn’t always keep them safe. At the height of flu season, few if any wore masks. You want to wear a mask every day then go for it. Masks do reduce blood oxygen saturation, and concentrate bacteria for you to rebreath, over and over. Go for it. It protects you from jack and crap.
Going outside the optimal range is not unsafe.
I missed that, in the links that have been posted to you, providing the optimal range, that YOU said was WRONG and that YOU requested.
Links have been given to you.
So, AGAIN, PLEASE PROVIDE A LINK, to where experts say “going outside optimal range is NOT UNSAFE”, and how long these experts claim is safe to do so.
Lol!!! Now we finally know her secret.
No mask.
;-)
“Links have been given to you.”
No link has been provided that say < 19.5% is unsafe per OSHA.
try wearing a mask while physically working for 12 hrs...

and clarification from OSHA on the specs: https://www.osha.gov/laws-regs/standardinterpretations/2007-04-02-0
I had a little notebook when I was a kid and would cut out and past different news items in it....the Thresher is in there....

Odd game you play.
Okay, how about you provide a scientific link (finally ;) that says it’s perfectly safe, per OSHA, to work in a prolonged (you know, like a work day) atmosphere or situation, with 19.5 %, or less?
Truth.
29 CFR 1910.134
Thanks for the links.
Lots of great, OSHA qualified info, regarding oxygen level requirements and standards.
But, you should have posted those to Texas gator. S/he’s the one needing additional proof.
;-)
“Odd game you play.”
No. The article says that <29.5% is unsafe. All I am asking is for the OSHA regulation that says that.
“Okay, how about you provide a scientific link (finally ;) that says it’s perfectly safe, per OSHA, to work in a prolonged (you know, like a work day) atmosphere or situation, with 19.5 %, or less?”
Do you realize that going to 3000 feet Altitude you will have less oxygen than 19.5% at Sea level?
From people that don’t know what they are talking about.
“29 CFR 1910.134”
Anyone can pull a number out of the internet. What is your point?
