The major difference (Apart from the electrocution risk when doing extractions) is that in an EV fire, Hydrogen Flouride can also be released, which is an uber nasty colorless gas.
From what I was explained it is a grim mechanism, the gas reacts with water, forming a highly corrosive acid. In humans the gas reacts with the moisture in your eyes and your airway forming an acid and doing a massive chemical burn. You basically choke with burned lung tissue while going blind all at the same time.
Gas detection was a big health and safety component in an EV charger company I worked for in the past.
