Dear Mr. Brent:

This is in response to your inquiry addressed to our Chicago Regional Office concerning sectionalized rail systems. This also confirms a telephone conversation between you and a member of my staff.

In 29 CFR 1910.23(e)(1), there is a requirement that the top rail of a standard railing be smooth-surfaced throughout the length of the railing. This means that the surface of the rail regardless of the shape shall be free from projections or irregularities that could injure employees' hands.

The sectionalized rail systems depicted in drawings 2A, 2B, 3A, and 3B free from projections or irregularities that could be injurious to hands appear to meet the smooth-surfaced requirement in 29 CFR 1910.23(e)(1).

If we may be of any further assistance, please feel free to contact me.

Sincerely,



Grover C. Wrenn Director,
Federal Compliance
