Eh. That’s not really comparable to lithium-ion batteries. Lithium-ion batteries are similar to bombs in that they’re highly dense stores of energy. If something goes wrong and that energy storage medium gets exposed to air, or there’s a failure in a charging safety mechanism, that’s a chemical fire at best, explosion at worse, but no matter what, it’s extremely toxic.

A car sitting 6 feet in the air is also a highly dense storage of energy that could be released at any moment. I do get your point, but there are ways to mitigate the dangers associated with working on a pack, and they’re not as volatile as you think. Being exposed to air isn’t going to cause a cell to explode as the lithium is mixed with other chemicals inside the cell to make it fairly inert. The danger comes from short circuits, whether it be a puncture or bridging contacts with something conductive.

Acetylene and oxygen is also explosive, but you’re still allowed to have it and use it. Battery acid is extremely corrosive and poisonous. Gasoline is extremely flammable. A garage is filled with dangers. If you can’t service a lithium-ion battery in a safe way, you shouldn’t do it, just like you shouldn’t service your brakes if you don’t know what you’re doing.

Have you ever attached jumper cables to a dead lead-acid battery?

Lead-acid batteries also present a risk of explosion.

That’s why you attach jumper cables to the dead battery first.

Lol. A single gallon of gasoline contains approximately 34khw of energy. An EV with ~300 miles of range, will have a battery with between 80 and 100 khw. Or the same potential energy as about 3 gallons of gas.

People are familiar with gas, so it seems safe. But every gas tank is a literal bomb, and that’s just for a car. I have no idea how big the storage tanks at gas stations are, but I’m assuming there’s enough explosive in there to level a couple hundred square feet if one of those goes.
