SCISSOR LIFTS

By Jill Hoffmann

STATISTICS 3/4 of tip-overs resulted in fall deaths—in the

remaining accidents, workers died from being struck by the falling scissor lift

2/5 of the tip-overs occurred when the scissor lift was extended over 15 feet, mostly while driving the lift

STATISTICS (Cont.)

In 1/5 of falls the worker was ejected from the scissor lift, mostly when an object struck the scissor lift.

Other fall deaths occurred after removal of chains or guardrails, or while standing on or leaning over railings.

operations

TRAINING REQUIREMENTS Employees should be trained on:
