Allowing the quote to be affected by the punctuation around it seems to undermine the “verbatim”-ness of a quote. If the period goes outside of the quote, then the quote is always a discrete unit of text that can be moved around the sentence as needed.

Example:

He said, “It’s fine”.

“It’s fine”, he said.

I would accept always including the period inside the quote for that case, but it causes other problems. If you put the period inside the quote, how do you indicate a quote that must end in a period, but does not end the sentence?

Example:

The spec sheet read “88 m.p.h.” on the back.

Or whenever I please, as in feisty and seize!

I’m no expert, so I can’t tell for sure, but my guess is that they’re storing two different chemicals. The left one looks like it’s a non-flammable, extremely hazardous material that shouldn’t be exposed to water (maybe an alkali metal, like lithium or sodium). The right one is a hazardous material that is a fire hazard above 93°C (200°F), but otherwise stable (maybe some kind of diesel?)

So… If I had to take a wild guess, diesel and lithium batteries?

It sounds like when a person stammers or mumbles because they’re uncertain.
