Bill,
Check the cartridges or the filters on your mask. Ammonia uses a different type of
cartridge than for acetic acid. any good safety supply store should carries these as
stock items, perhaps even a combination cartridge to both ammonia and acid gases.
Though an organic vapor mask may work for glacial acetic acid as well, since it is an
organic acid.
