^-- Quitting smoking while pregnant can be very hard on the body, the baby, and the mother's mental health. Depending on the circumstances and risk factors, it may be advisable not to quit smoking during a pregenancy. Again, just shows you can't always judge a book by it's cover, and furthermore that "common sense" gut reactions to things isn't always correct...
Getting back to the topic I think the OP only got really defensive after being continually attacked for even asking the question. There is a bizarre undercurrent to this thread with a chorus of voices saying "this shouldn't be talked about, why are we talking about this, please stop talking about it", which is doubly bizarre when the topic itself which concerns a known hazardous material.
If you don't have anything to add to the thread, saying "There is nothing to talk about" as a reply also adds nothing, is needlessly hostile towards the OP, and adds absolutely nothing to the conversation.
If people have external sources which detail the process and methodology that Focal uses in manufacturing Be in their products safely, that is useful knowledge, but I would again point out that the OP reached out to Focal, Focal *DID REPLY* saying they would get back to him, and then *AFTER THAT* proceeded to ignore him. That chain of events is poor customer service, and furthermore, it seems like common sense that even if there was a legal liability with producing Be in consumer products, Focal should have a good answer to concerned customers. If they can assure so called experts, doctors, and even governments that their products are safe - why can't they also reassure customers? "Legal reasons" is a very lame excuse for a customer who is concerned, and I would agree with others, if that answer does not sit well with you as a customer, you should move on to other products.
Finally, even if people present external sources which document Be safely used in other products, I also think the onus is on the company manufacturing the hazardous material into consumer products itself to prove it's usage is safe. Leaning on doctors, so-called experts, and government bodies to provide safety standards is misunderstanding the entire history of how safety standards get developed in the first place, which is typically due to systemic failures with doctors, experts, and government bodies in the first place. They are a safety net, but the real driving force behind higher standards are everyday concerned citizens who loudly speak about potential issues.
Some recommended reading for those unfamiliar with some of this history:
