No winze or raise shall be in a direct line with a haulage drift unless such a location is essential to the usage to which the winze or raise is to be put. In such exceptions, guards and protective covering must be provided so that hazards of personnel are no greater than would exist if the winze or raise was not in a direct line with haul- age drift.
