When was emergency O2 "required" in standards

[Louma]

I am looking for a way to find the earliest reference in any agencies standards for a instructor to "have oxygen available in case of an emergency". The answer - contact the agencies might not be good enough. My first go around got me nowhere. Thanks in advance.

Although PADI widely recommends oxygen, they do not require it except while conducting the Rescue Course. Can’t determine when that started, but it goes back at least eight years.

Actually thats not totally correct. If the course is being run by a PADI Dive Center or Resort then PADI Resort & Retail Association (IRRA) standards do require that oxygen be available, and that has been the case for some time.
