In none of those did we know about the adverse effects. Those were observed afterwards, and it would have taken longer to know if they hadn't been adopted. But that doesn't invalidate the idea that we have followed "if something bad, collectively don't use it" at various points in time.

The man who invented it got lead poisoning during its development, multiple people died of lead poisoning in a pilot plant manufacturing it and public health and medical authorities warned against prior to it being available for sale to the general public.
