An elevator installation comprising a car (1) within a shaft (10), a buffer (16) mounted in a pit (12) of the shaft (10) and a barrier (20;30;40) located in the pit (12) surrounding or within an area wherein a vertical clearance between the pit floor (14) and the car (1) or equipment mounted thereon is less than a regulatory threshold value (C) when the car (1) fully compresses the buffer (16). Accordingly, the barrier (20;30;40) acts to physically deterrent personnel within the pit from inadvertent presence in the area of reduced vertical clearance.
