Awl --
Any thoughts on this, esp. on how likely this all is? Anyone with personal experience?
But what are the likelihoods? wrt to various oils, grease? Motor oils?
A very cautious shop-type friend says this happened to him, burned down part of his house.
Grease fires in vents are a little more understandable, given their proximity to exhaust heat and poss. sparks, but still seems like a long shot. But something to consider, esp. in an old house. I wonder what the buildup is like, with good modern filters. With old mesh washable filters, I saw no buildup in vents that had to be over 30 years old, altho not sure of the cooking hours on these vents.
But I do know that if I were freezing in the wilds with my oily rags and kitchen grease, hell would freeze over before I would be able to ignite this stuff. heh....
