Electrically Non-Conductive Ladder Fall Protection

摘要

NASA's Kennedy Space Center developed an electrically non-conductive ladder fall protection system for the Launch Complex (LC) 39B lightning towers. The towers include a 100-foot fiberglass mast at the top of the tower structure. The fiberglass masts insulate the metallic tower structure from the lightning strike protection system that is housed at the top of the fiberglass masts. All of the components contained within the fiberglass mast are required to be electrically non-conductive including bolts, screws, washers, ladders, and platforms. A 100-foot vertical ladder runs through the longitudinal center axis of the fiberglass mast, allowing for a service access at the top of the mast. Occupational Safety and Health Administration (OSHA) standard 1910.28(b)(9) requires that fall protection on fixed ladders of 24 feet or taller be installed on or after November 19, 2018.
