That is the best advice for disconnecting batteries, negative cable first off, last on.
I had a long discussion with a fireman at MCACN a few years back because he was telling people to remove the Positive cable ! I tried, in vain, explaining to him that it was actually not safe doing it that way......and he said....."That's the way our Chief wants it"
