Mindless pig ignorant waffle. Have fun explaining why
its so rare with unvented natural gas room heaters.

Now it's "so rare" instead of never? Who's waffling now?

My mother was on a coroner's inquest
about someone who died from CO poisoning.

Because of dustbunnies obstructing a natural gas appliance's air supply.

Easy to claim. Hell of a lot harder to actually prove.

Proving what went wrong is what coroner's inquests _do_,
and that's exactly what they did.

And it wouldnt happen with a dryer anyway, they
have fans that most natural gas appliances dont.

Not if the lint filter has been allowed to clog, or,
a misplaced sock ended up where it shouldn't.
