CTSP Aerial Lift Operations Safety 4

Question 1

Which type of aerial lift is specifically designed for tree care work and allows 360-degree continuous rotation?

Accepted Answer

Articulating knuckle boom with continuous rotation

Answer

Articulating knuckle booms with continuous rotation are preferred in tree care because they allow full access around a tree without repositioning the truck.

Question 2

Before entering the aerial lift work zone, what must a tree care crew establish?

Accepted Answer

A hazard communication plan and designated drop zone with cones or flagging

Answer

Establishing a defined drop zone with visible barriers and a hazard communication plan protects ground crew and the public from aerial hazards.

Question 3

What is the primary purpose of the boom's load moment indicator (LMI) or capacity chart on an aerial lift?

Accepted Answer

To warn the operator when the load and reach combination approaches the machine's tip-over limit

Answer

The LMI or capacity chart tells operators the safe load limits at various boom angles and extensions to prevent tip-over caused by exceeding stability limits.

Question 4

A worker in an aerial lift bucket is struck by a falling branch and becomes unresponsive. The ground crew's first action should be:

Accepted Answer

Activate the ground controls to lower the bucket immediately

Answer

The ground crew must use the emergency ground controls to lower the incapacitated worker to safety as quickly and carefully as possible.

Question 5

Which hazard is unique to aerial lift operations compared to conventional tree climbing?

Accepted Answer

Tip-over of the support equipment

Answer

Tip-over of the truck itself is a hazard specific to aerial lift operations that tree climbers do not face; improper setup or slope can cause catastrophic vehicle overturn.
