s in mines.=] The owner, lessee or agent of each
mine shall provide an enclosed lard or signal oil lamp or lantern or
incandescent electric light at such point or points in the mine as
may be necessary for the proper safety of persons, especially at the
top of extreme grades. No open light shall be used for fixed or
stationary purposes; no open torches or lamps larger than the lamps
provided for in this act for use as open lights, and no coal oil or
kerosene lamp or lanterns, shall be used in a mine. This, however,
shall not prevent the use of a torch or blow-torch for mechanical
purposes other than illumination. (Sec. 961.)

[=Light or signal on locomotives and trains.=] The owner, lessee or
agent of a mine at which locomotives are used for hauling the coal,
shall keep a light on the front end of the locomotive when it is in
use, and when the locomotive is run ahead of the trip, and the
trip-rider is not required to ride the rear car of the trip, a
signal, light or marker, approved by the district inspector of
mines, shall be carried on the rear end of the trip to indicate when
the trip has passed. Cars shall not be pushed ahead of the
locomotive where it can be avoided, and when cars are run ahead of
the locomotive a light shall be carried on the front end of the trip
and the cars shall not be moved at a speed greater than four miles
per hour. When rope haulage is used, an enclosed light shall be
carried on the front end of each train so hauled. When a mechanical
haulage trip passes through an automatic door having no attendant
other than persons in charge of such trip, the trip-rider shall be
required to ride the rear car of the trip while passing though such
door, and see that it closes after the trip passes through. (Sec.
923, 958; Penalty, Sec. 976.)

Sec. 944. [=Employment of minors.=] The owner, lessee or agent of a
mine shall not employ, or permit to work therein, any boy under
fourteen years of age; nor employ, or permit to work therein, any
boy under fifteen years of age during a term of the public schools,
in the district in which he resides. (Sec. 912, 953.) (See Child
Labor Law, Sec. 13002, page ----).

"The provisions of Section 912, 944 and 953 G.C. do not
permit the employment of children under 16 years of age in,
about or in connection with any mine. Such employment is
governed by the provisions of Section 13002 G.C."
