It is a safe light, Acetylene being less poisonous than coal gas. As the issue from an open burner is so small, it would have to be left open for a very long period in a closed room to render the air dangerous to breathe. The slow issue of gas is also an element of safety against explosion, for a burner would require to be left open several days to make an explosive mixture in a room.
A good and reliable Generator is of course necessary to ensure the foregoing.
New piping, if required, is inexpensive, as it only needs to be one-third the size of piping for coal gas. Small pipes are inconspicuous when run in finished rooms.
The Generator here illustrated is the Cavendish “A.B.C.” (automatic), and is considered the most simple and economical now before the public. The attention needed that of a lad or odd man, is not more than ten minutes daily, and much less than the time required by lamps. There are no mechanical parts except two water taps, and nothing to get out of order or readily wear out. The generating apparatus consists of the central gas holder, on each side of which is a generating chamber and a condenser. The generating chambers are in duplicate and work independently, which is a great advantage in admitting of re-charging always being done in daylight without wasting unspent material. The gas given is cool and clean. There is no compression of gas or variable pressure from the holder. There is a positive working escape pipe if the holders should be carelessly over-charged. The Insurance Companies charge no extra premiums where this Generator is used.
