A continuous safety railing of not less than 3/4-inch iron should run around the sides and ends of the tank
at a height of not less than 30 and not more than 60 inches above the platform. It should be securely fastened to

extend down the entire length on both sides and be fastened to upright corner posts. This kind of railing
requires an end handhold on each end of the tank that must extend to within 6 inches of the outer sides of the

length of the tank on each side. The minimum width of this running board on the sides is 10 inches, and on the
ends 6 inches. Figure 7.3 shows side and end running boards.
These cars must have sill steps located at each end on each side under the side handhold. The outside edge
of the tread of this step is not more than 4 inches inside the face of the side of the car and preferably flush with
