13. CARE AND MAINTENANCE.--All charging and cleaning of apparatus,
generation of gas and execution of repairs must be done during daylight
hours only, and generators must not be manipulated or in any way tampered
with in the presence of artificial light.
This will require gasholders of a capacity sufficient to supply all
lights installed for the maximum lighting period, without the necessity
of generation of gas at night or by artificial light.
In the operation of generators of the carbide-feed type it is important
that only a limited amount of carbide be fed into a given body of water.
An allowance of at least one gallon of generating water per pound of
carbide must be made in every case, and when this limit has been reached
the generator should be drained and flushed, and clean water introduced.
These precautions are necessary to avoid over-heating during generation
and accumulation of hard deposits of residuum in the generating chamber.
(Rule 14, referring to the storage of carbide, has been quoted in Chapter
II. (page 19)).
RULES FOR THE CONSTRUCTION OF GENERATORS.
The following Rules are intended to provide only against the more
hazardous defects usually noted in apparatus of this kind.
