27-348. Shaft stations
Stations or levels shall have a passageway around the working shaft so that crossing
over the hoisting compartments may be avoided. Sumps shall be securely covered. At
shaft stations a gate or guard rail shall be provided and kept in place across the shaft,
except when a cage, skip or bucket is being loaded, but may be temporarily removed for
repairs or other operations if proper precaution is taken to prevent danger to
persons. The top of the shaft shall be protected by a substantial gate or guard rail.
