Floats should
not be used except where failure will only render the machine inoperative.
It should be said that the National Board of Fire Underwriters have
established an inspection service for acetylene generators and any
apparatus which bears their label, stating that that particular model and
type has been passed, is safe to use. This service is for the best
interests of all concerned and looks toward the prevention of accidents.
Such inspection is a very important and desirable feature of any outfit and
should be insisted upon.
_Location of Generators._--Generators should preferably be placed
outside of insured buildings and in properly constructed generator houses.
The operating mechanism should have ample room to work in and there should
be room enough for the attendant to reach the various parts and perform the
required duties without hindrance or the need of artificial light. They
should also be protected from tampering by unauthorized persons.
Generator houses should not be within five feet of any opening into, nor
have any opening toward, any adjacent building, and should be kept under
lock and key. The size of the house should be no greater than called for by
the requirements mentioned above and it should be well ventilated.
The foundation for the generator itself should be of brick, stone, concrete
or iron, if possible. If of wood, they should be extra heavy, located in a
dry place and open to circulation of air.
