Aerial Lifts
Most aerial lifts have extensible or articulating mechanisms that can position workers up, down, or sideways.
Most accidents involving aerial lifts can be traced to untrained or improperly trained workers.
ANSI defines and sets operating standards for four different types of aerial lifts in ANSI/SAIA A92.22-2018, Safe Use of Mobile Elevating Work Platforms (MEWPs).
How Aerial Lift Falls Occur
Most accidents involving aerial lifts can be traced to untrained or improperly trained workers. Reasons for falls:
- A hydraulic cylinder fails and causes the boom to drop.
- Outriggers are not used or improperly placed and the lift vehicle overturns.
- Workers are not tied off while they are in the bucket.
- Workers fall or are pulled off the platform when the lift vehicle is struck by another vehicle or moves unexpectedly.
