Shafts to be securely timbered.
Every shaft, incline, slope,
tunnel, level or drift and any working place in the mine shall be, when
necessary, kept securely timbered or protected to prevent injury to any person
from falling material. It shall be the duty of the operator to carry out and
enforce the provisions of this rule, but nothing contained herein shall be
construed to relieve the miner from the duty of caring for his or her own
working place, except as hereinafter provided.
