One dead, one injured in elevator fall at construction site in Missouri.
NIOSH 1985 Apr; :1-4
A fatal accident circumstances and epidemiology report on an accident involving an elevator fall at a construction site is presented. The report is part of a NIOSH project in which data on confined space or electricity related accidents are collected. On March 13, 1985, two workers were attempting to hook the permanent hoisting system to an elevator that had been assembled in the shaft and raised to the sixth floor of a building by a temporary hoisting system. The accident occurred when the elevator car descended unexpectedly and suddenly 75 feet to the bottom of the pit. Both workers were found atop the elevator. Both were injured, one fatally. The fatally injured worker was found draped across the cross head attached to the roof of the elevator car. It was believed that he fell until he struck the crosshead, a rigid steel structure, and received severe multiple injuries including a severed spine and broken neck. The survivor's injuries were less severe. He was assumed to be have been in constant contact with the elevator car top. Upon impact, the flexible roof of the elevator absorbed much of the energy. No conclusive cause for the accident could be determined. The governor may have been accidentally tripped, improperly adjusted, or not functional. Recommendations include testing the operating parameters of the governor and not using the elevator safety system as the primary holding device.
