 (f)  American and Continuous System Rope drives, so located that the conditions of the rope, particularly the splice, cannot be constantly and conveniently observed, shall be equipped with a telltale device, preferably electric bell type that gives a warning when the rope begins to fray.

 (g)  The guarding of belts, ropes and chains shall be by one of the following methods:

   (1)  Vertical belts, ropes and chains when required to be guarded shall be enclosed to the upper pulley, sheave or sprocket guard or to a height of at least 6 feet from the floor or working platform when the guard is not more than 4 inches from the belt, rope or chain at any point, or to a height of 5 feet if it is between 4 inches and 12 inches from the belt, rope or chain at any point. Guarding by standard railing may be used when approved by the Department if the railing is at least 15 inches but not over 20 inches from the belt, rope or chain at all points.
