Another quirk of nested containers. If you happen to be smoking and you drop the pack or whatever that your lit cigarette is contained in, prepare to lose everything you dropped in a fiery conflagration, assuming that it simply doesn’t just catch you ablaze as well. When people smoke, they obviously keep the thing they’re smoking in their pocket or their backpack, rather than between their fingers or lips. That just makes sense, right?
I’ve brought this up before. It’s nonsensical for dropped cigarettes to be such a fire hazard. They simply do not burn hot enough to catch fabric ablaze, most of the time. The old quadriplegic I used to work for has the burn scars on his chest to attest to that, from when he fell asleep with a lit cigarette or dropped a cherry on himself. They’ll singe a hole in something they’re dropped on, sure enough, but you aren’t generally going to see a cigarette cherry cause something else to burst into open flame.
I’m aware of the isolated reports of people dying in their beds from reportedly falling asleep smoking, but that’s hardly the case most of the time. Those events are tragedies that have been blown heavily out-of-proportion by people who wanted to use them as anti-smoking propaganda.
Drop a lit cigarette into a pile of shredded paper in a contained space, yeah, I can see how that might catch fire. The conditions for catching fire in that situation are extremely favorable. Onto a standard blanket or bed, or a backpack, not so much.
