Not sure if this is the appropriate way to handle this but here is @FloofahNZ@lemmy.nz'a comment. If they want to repost it themselves I can delete this one:

I’d guess the contractors were not properly instructed. This brings a point, who were the contractors working on this? Did they have any relevant experience, or were they simply casual labour?

I’d expect all procedures to be fully documented and importantly regimented into crews. But seemingly not in this case, how the hell could this happen?
