(5) No corrosive fluids or gases that may escape from any lithium ion battery may damage surrounding structure or any adjacent systems, equipment, or electrical wiring of the airplane in such a way as to cause a major or more severe failure condition
Quoting RickNRoll (Reply 130):
It doesn't say "fluids or gases that may escape", it says "NO corrosive fluids or liquids that may escape", there is a big negative at the start of that sentence. So I asked, in his terms, does that mean that they have changed their minds, since their statement clearly indicates that corrosive fluids or liquids that have escaped are an issue for them.
If the word "that" was not in the sentence, your interpretation would be correct.
But it is not correct, because "that" is there.
Maybe it is easier if you pull out the subject and break it into phrases.
No corrosive fluids or gases that may escape from any lithium ion battery.....
[nothing that escapes]
may damage surrounding structure or any adjacent systems, equipment, or electrical wiring of the airplane ....
[may damage stuff around it]
in such a way as to cause a major or more severe failure condition,
[in a bad way]
"Nothing that escapes may damage stuff around it in a bad way."
If stuff does escape - but does not damage anything around it
... you are okay
If stuff does escape - and damages stuff around it,
... but does not damage it in way that make the airplane go bad
... you are okay.
Making a mark, making a stain, such-n-stuff - is allowed.
Maybe item 5 needs to be re-written - and it may as a result of this - but that is the way it is written.
(I can't believe I'm still doing this....)
