Yes, there are industry standards regarding horizontal lifelines.  29 CFR 1910 and I believe 29 CFR 1926 (CFR = Code of Federal Regulations) both discuss horizontal lifeline sytems (I'm more familiar with the 1910 provisions).  There's also an excellent book you can buy from the American Society of Safety Engineers,  Introduction to Fall Protection, 3rd Edition J. Nigel Ellis, Ph.D., CSP, P.E..  Also checkout the ANSI Z359 standard.  Horizontal lifeline systems need careful consideration due to cable deflections & restraint points.  You may also want to consider purchasing a horiztonal lifeline system from someone like DBI / SALA that is preengineered and you need only worry about proper restraint to the structure.

Subject: Life Line Reference

I received an inquiry today from a steel fabricator regarding criteria for installation of a life line cable around the perimeter of upper level floors. He's proposing use of an eyebolt spaced along the steel spandrel beams at each floor. The eyebolts will support the cable life line to which the workers can attach their safety harnesses. Are industry standards (OSHA?) available that provide guidance or criteria for this situation?
