They must be so arranged that the escaping
gases and vapours cannot enter rooms or chimneys.
6. The contacts of any electrical warning devices must be outside the
apparatus shed.
7. Acetylene plants must be prevented from freezing by erection in frost-
free rooms, or by the employment of a heating apparatus or other suitable
appliance. The heat must only be that of warm water or steam. Furnaces
for the heating appliance must be outside the rooms containing
generators, their subsidiary apparatus, or holders; and must be separated
from such rooms by fire-proof walls.
8. In one of the walls of the apparatus shed--if possible not that having
a door--a window must be fitted which cannot be opened; and outside that
window an artificial light is to be placed. In the usual way acetylene
lighting may be employed; but a lamp burning paraffin or oil, or a
lantern enclosing a candle, must always be kept ready for use in
emergencies. In all circumstances internal lighting is forbidden.
9. Every acetylene installation must be provided with a main cock, placed
in a conveniently accessible position so that the whole of the service
may be cut off from the plant.
