Abstract
An elevator installation includes a car within a shaft, a buffer mounted in a pit of the shaft and a barrier located in the pit surrounding or within an area wherein a vertical clearance between the pit floor and the car or equipment mounted thereon is less than a regulatory threshold value when the car fully compresses the buffer. The barrier acts to physically deter personnel within the pit from inadvertent presence in the area of reduced vertical clearance.
