OSHA respirator use regulations

I've been told that OSHA mandates fresh air for workers using respirators every hour. The person who told me this is not entirely reliable, so I'd like some confirmation. I seem to recall something similar but from a confined spaces instruction. I also recall reading that respirators reduce oxygen intake by about 5%.

Is there any regulations on the length of time respirators may be used in the workplace? It'd make healthcare jobs difficult if not impossible if true. Then again, I don't believe that health advice should be based on political considerations.

Also, would it be okay if I post this question on the Science Desk as well? Thank you. 161.185.161.32 (talk) 17:20, 30 July 2021 (UTC)[reply]

It's best to keep things on one desk. With regard to OSHA's regulations, this seems to be the main page for that. Maybe you can find it there. --Jayron 32 17:36, 30 July 2021 (UTC)[reply]

There was a study claiming(?) that kids wearing masks could be endangered by CO2 buildup in the masks, but that study was retracted.[[1]] I don't know whether that's relevant to your question. 2601:648:8202:350:0:0:0:2B99 (talk) 22:27, 30 July 2021 (UTC)[reply]
