The gauge must not show a loss after generator has
been turned off for at least two hours.
20. After the fittings (pendants, brackets, &c.) have been fixed and all
burners lighted, the gas shall be turned off at the burners and the whole
installation shall be re-tested, but a pressure of 5 inches shall be
deemed sufficient, which shall not drop lower than to 4-1/2 inches on the
gauge during one hour's test.
21. No repairs to, or alterations in, any part of a generator, purifier,
or other vessel which has contained acetylene shall be commenced, nor,
except for recharging, shall any such part or vessel be cleaned out until
it has been completely filled with water, so as to expel any acetylene or
mixture of acetylene and air which may remain in the vessel, and may
cause a risk of explosion.
_Recommendation_.--It being the general practice to store carbide in
the generator-house, the Association recommend that the carbide shall be
placed on a slightly raised platform above the floor level.
THE BRITISH FIRE OFFICES COMMITTEE in the latest revision, dated July 15,
1907, of its Rules and Regulations _re_ artificial lighting on
insured premises, includes the following stipulations applicable to
acetylene:
Any apparatus, except as below, for generating, purifying, enriching,
compressing or storing gas, must be either in the open or in a building
used for such purposes only, not communicating directly with any building
otherwise occupied.
