Its not just firefighters, but people who live in shared buildings -- apartment, condominium, co-op, etc. In which case, it would appear evident to me that the real policy issue is one of allowing smoking indoors.
Unfortunately the bureaucratic process tends to lean towards spending enormous amounts of time and resources on issues that could be "hacked" fairly easily.
When we add a lot of variables to a problem we end up with solutions that not only are challenging to rationalize, but also tend to have ugly side effects. This is something I've learned from running my own business, and it seems to be reflected on a government level as well.
Kind of tangentially, down is one of the few products where the "humane" way to harvest involves killing the animal; the "pluck living geese over and over again" method is apparently quite painful for them.
I've been to sheep-shearings - as long as the sheep is regularly sheared, it'll know what's going on and won't be upset; it's not painful (as long as the person with the trimmer is expert enough not to nick the skin), and the wool starts peeling off in chunks anyway if you don't shear it during the summer.
Caveat: I have no idea if there's some horrible mechanized way to shear sheep at greater scale. But on the smaller scale the most efficient way is to keep the sheep calm and cooperative. The cheapest way to keep large numbers of sheep also seems to be to let them wander over a large area of cheap land (rocky, steep, uneven, etc. -- unusable for cow grazing or farming is just fine). On the Isle of Skye in Scotland there are simply sheep wandering everywhere, often in the roads, as the sheep farmers don't always bother with much fencing.
