Orphaned references in Diving hazards
I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Diving hazards's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "P D Handbook": From Gas blending:  From Diving suit:  From Diving bell:  From Saturation diving:  From Hyperbaric welding:  From Diving supervisor:  

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT ⚡ 15:42, 22 July 2020 (UTC)
