Good points. I tried studying just one small facet of combustion known as the Maillard reaction , as it pertains to food. The short answer is hundreds of interesting (and tasty, though arguably not healthful) substances are created at varying rates and varying times and amounts in an incredibly complex way in every square inch of pan, slightly differently. Even just concentrating on a single food item was reminiscent of Pirsigs ‘the art of motorcycle maintenance’ in the madness of trying to definitively say what is going on in any specific batch. I’m not knowledgeable about previous accidents, how they played out, or what level of testing was performed and by who. But partial combustion thermal decomposition of mixed chemicals is a nasty fucking cup of tea, and in my opinion it’s far far worse on a long term health basis than anyone believes right now. Hell, your proximity in miles to a freeway or a port can change your children’s chance of developing asthma by orders of magnitude. It’s slow, quiet, and hard to assign blame years later. Regardless of who’s to blame, you only get one life and the thought of losing a large chunk of it to shifty toxic smoke is terrifying to me. Someone wrote you should get your health. He led now to have it on record in case you have issues… if you have issues through it’s likely something horrible and terminal, and duck that.
