Paragraph 16

In relation to each shaft, staple-pit and unwalkable outlet provided with winding or haulage apparatus the manager shall determine any signals necessary for the proper operation of that apparatus, and, in particular, where there is more than one entrance underground to such a shaft, staple-pit or unwalkable outlet he shall determine the signals to be used to indicate the entrance to or from which the cage, carriage or kibble is to be raised or lowered.

There shall be kept posted at each entrance for the time being in use to each such shaft, staple-pit or unwalkable outlet, and in the place at which is operated the winding or haulage apparatus provided therefor, a notice specifying the signals determined by the manager for transmission therein.
