Dear Mr. Osborne:

This is in response to your inquiry concerning the positioning of the safety line on billboards for the protection of employees.

The method of protecting employees working on elevated billboard platforms two to three feet wide, with a safety belt and lanyard 4 feet long attached to a safety line approximately 12 inches above the platform does not comply with the intent of 29 CFR 1910.23(c)(1). However, a system designed (such as shorting the lanyard) so as to prohibit employees from backing off the front edge of the platform, thereby preventing any fall possibility would appear to comply with the intent of the standard.

If I may be of further assistance, please feel free to call or write.



John K. Barto Chief,
