Key Questions
What is an aerial work platform?
A temporary workspace that can be used as an alternative to ladders or scaffolding.
What are the common parts of an aerial work platform?
The chassis (or base), the boom, and the platform or basket.
What are some types of aerial work platforms?
Extensible boom platforms, articulating boom platforms, and vertical towers.
What are some requirements regarding aerial work platforms?
The platform must have guardrails, intermediate rails, and toe-boards on all open sides, or must be fully enclosed; and signs or labels that indicate the safe working load limit and the safe operable wind speed limit be must posted.
How many sets of powered controls does an aerial work platform have?
Two, one on the platform and another on the chassis. The lower set of controls must be able to override the upper set, but only in emergencies or when the person being lifted gives permission.
What are some common causes of injuries and accidents?
Overturning, falling, collision, and electrical shock.
What are some safe work practices when working with aerial work platforms?
Obey the load limit; operate only when under the maximum safe wind speed; evaluate the ground for proper support capacity; place platform on safe grade that’s less than maximum allowed incline; only use outriggers in fully extended position; ensure adequate clearance of buildings, structures, and power lines; never use aerial work platform as a crane or hoist.
Sample Video Transcript
While working on an elevated platform, follow these safe work practices. Always use a personal fall arrest system when occupying the platform or basket. This includes a full body harness attached with a lanyard from the D-ring in the back of the harness to the manufacturer’s anchor point in the basket or platform in a manner that minimizes the fall distance. Do not tie off to any part of the guardrail system nor to nearby poles, structures, or equipment. If the platform or basket does not have an approved anchor point, a personal fall protection system cannot be used. Always stand firmly on the floor of the platform, and wear approved footwear for good traction on the platform. Never step or stand on objects present on the platform floor.
