Each mine shall have a check-in and check-out system which
will provide positive identification of every person underground
and will provide an accurate record of the persons in the mine
kept on the surface in a place that will not be affected in the
event of an explosion. Said record shall bear a number or name
identical to the identification check that is securely fastened to
the lamp belt of all persons underground. The identification check
shall be made of a rust-resistant metal of no less than sixteen
gauge.
