Look closely, the 5400lb requirement may be the caternary reaction at the supporting steel member. -----Original Message----- From: RajSTC(--nospam--at)aol.com [mailto:RajSTC(--nospam--at)aol.com] Sent: Tuesday, November 16, 1999 7:36 AM To: seaint(--nospam--at)seaint.org Subject: Fall Protection System - Loading Recently, I was involved with the design of a fall protection system, for personnel engaged in activities on top of trucks in petroleum product loading rack. I was asked to follow OSHA guidelines. According to OSHA, "Lifelines shall be secured above the point of operation to an anchorage or structural member capable of supporting a minimum dead weight of 5,400 pounds". Design based on this requirement resulted in lot of structural steel, which seems to me to be an overkill. The project was on a fast track, so I could not do enough research before sketching the details. Now that the project is behind me (except for comments from all those self-styled structural engineers, like "which idiot designed this ?") I can get to the bottom of the design philosophy. I am curious to know the basis on which OSHA came up with their recommendation. Yes, it is a dynamic problem, but what assumptions or tests led to the 5,400 load? Am I justified in stressing the steel members to their yield limit, considering the loading to be extraordinary? Is it possible to get theoretical basis for the recommendation etc. I am looking forward to some lively discussions on the topic. Thanks, in advance. Raj.
