A more accurate announcement would reflect a caution against using silver coated pipes for acetylene transport or high silver solders for joining any pipe work that risks internal exposure to the gas. Using the gas itself (as a fuel) to weld with / using high silver alloys isn't a problem though. I dimly recall in my locale there was a prank back in the 80s that used a Silver acetylide solution that had been dried onto some surface ... but only small milligram [1] amounts I guess.
