Whether or not specific regulations exist for a particular danger, if a company or individual can be found to be aware of the negative consequences of their use of certain compounds and they don't publicly document those dangers they can (in the US anyway) and should absolutely be held legally accountable for failure to warn.
History is rife with companies/industries who were well aware of the dangers they were creating to people for decades while actively suppressing the evidence of such that they themselves discovered.
Which companies this applies to for Asbestos in particular, I couldn't tell you, but it would be shocking if there weren't lots of bad actors who knew they were bad actors considering there has been research on the dangers of Asbestos since 1927 -- nearly a full century ago.
