Just wanted to add that these MSDS's are useful but don't tell the entire story. They hint to the dangers of a fire and the vapors but don't give any details. See my attached advertisement for PlaneGard. There are links to GM and Tesla that know a lot about the dangers of the vapors from a Li-ion battery in thermal runaway. It will explain that the vapors coming from a Li-ion battery fire are poisonous and may even kill you. Some of the by-products of the burning electrolyte are known "neurotoxins" developed first during WWII.
As some of you know, I joined your group because I am a battery expert and know how to cause a battery to catch fire and how to avoid it. I also market a special insulated case (aka PlaneGard) to protect passengers on an airplane from Li-ion battery fires (a burning Li-ion battery is very dangerous in an enclosed space of an airplane or a car). We sell PlaneGard to the airlines and owners of private jets. Some of the private jet people are worried about carrying drone batteries of passengers on their airplanes and therefore say they relax and can store the drone battery in PlaneGard during the flight. Then if the battery just happens to catch fire, the fumes and vapors are fully contained by PlaneGard and its poison gas filters. See
www.PlaneGard.com for lots of information and cool videos of battery fires. For what it's worth.........
