§ 19.09.

Such passageways must be so graded and drained that it will be impossible for water to accumulate in any depression or dip of the same in quantities sufficient to obstruct the free and safe passage of men. No passageway to an escapement shaft shall pass through a stable. At all points where the passageway to the escapement shaft or other place of exit is intersected by other roadways or entries, conspicuous signboards shall be placed indicating the direction it is necessary to take in order to reach such place of exit. New shafts and partitions therein shall be fireproof. Buntons and guides may be of wood.
