Okay, I’m really curious about this rationale. Why is a J-valve a safety hazard for filling a tank? Could you ask them to explain their reasoning.

IMO because the LDS people were either ignorant about J valves, equipment snobes or wanted to make a sale.

Tell them you are search and rescue diver who sometimes is in black water and can't see your SPG and OSHA requires one.

1910.424(c)(4)
A diver-carried reserve breathing gas supply shall be provided for each diver consisting of:
1910.424(c)(4)(i)
A manual reserve (J valve);

Those are the kind of A-holes that would ask for proof!

How about if I simply showed them these photos for proof?
