An. Code, 1924, sec. 129. 1922, ch. 307, sec. 128.

129. Whenever any working of a coal mine approaches a place sus-

safety lamp or other light approved shall be allowed or used.

An. Code, 1924, sec. 130. 1922, ch. 307, sec. 129.

130. Whenever safety lamps are required to be used in any mine, such
lamps shall be provided by the operator for maintenance and use of which
actual cost may be charged; and of such lamps a quantity one-fourth
larger than may be in immediate use shall always be kept on hand, ready
for use. A competent person shall be appointed to examine every such
safety lamp immediately before it is taken into the workings for use, who
shall ascertain that such lamp is clean, safe and secure before it is used.

An. Code, 1924, sec. 131. 1922, ch. 307, sec. 130.

131. No safety lamp shall be entrusted to any person for use in a
mine, until said person has given satisfactory evidence to the mine fore-
man that he understands the proper use, and the danger of tampering
with the same. No one, except a person authorized, shall have in his
possession any key or other instrument for unlocking any safety lamp,
while within any gaseous mine. Any person found, while within any such
mine, to have any such key or other instrument for unlocking any safety
lamp, or found opening or tampering with or to have tampered with any
such lamp, or to have matches or any unauthorized lighting device in his
possession, shall be deemed guilty of a misdemeanor; and any operator
or any person by such operator authorized, who shall fail to supply prop-
erly cleaned, safe and safely secured safety lamps for use in such mine
whenever necessary, shall be deemed guilty of a misdemeanor; Provided,
that this shall not prohibit the use of a flame in the intake air only, for
the purpose of making necessary repairs to machinery or wires, when in
charge of persons authorized to do such work.

An. Code, 1924, sec. 132. 1922, ch. 307, sec. 131.

132. The mine foreman, whenever in his opinion the mine is becom-
ing dangerous from accumulations of gas, and additional ventilation is
required, beyond the capacity of the ventilating equipment, shall notify
the district mine inspector, who shall make an immediate personal ex-
amination, and if such inspector finds that the ventilating equipment is in-
sufficient, he shall by special safety order require the operator to provide
adequate equipment, and if necessary to make additional openings from
the surface, or bore holes to furnish a vent in the case of gas accumulations.
