Yeah, LittleInch, the fellow was also "here on the visa from his employer" so it started from a highly awkward situation for the employee. Forget it, Jake, it's Chinatown. Keep in mind the vast numbers of similar visa from the employer folks are in Redmond, WA, and San Jose, CA, for example. Although they aren't likely to get into an OSHA tangle, they are not in a fantastic legal situation to be a whistleblower, similar to that guy.
The bit about "no jurisdiction," there's at least something to that, the thing only operated in international waters, the "passengers" were "crew members", etc. etc. etc. there was a lot going on and lot of nuance as well.
It looks like my question has been answered, there were quite a few dives, the vast majority weren't to that depth. 13 of 90 did not reach the target depth.
Titan sub only reached the depth of the Titanic on 13 out of 90 dives, says the waiver OceanGate passengers had to sign, Jyoti Mann, BusinessInsider.com, July 9, 2023, accessed 6/21/2024.
The OSHA regulations for the construction of the sub would apply to the workers on the site in the building performing any work on the site, it has nothing to do with the safety of the submersible. OSHA regulations apply to workplaces, so and Amazon warehouse, sure, but the regulations do not apply to the contents of the warehouses, because they aren't people.
