Question 1

What is the primary purpose of a pre-planned aerial rescue procedure in arboricultural operations?

Accepted Answer

To ensure a trained rescuer can reach and lower an incapacitated climber to safety within minutes

Answer

Suspension trauma and other injuries can be fatal within minutes, so a rapid, rehearsed rescue plan is life-critical, not just a paperwork exercise.

Question 2

Per ANSI Z133, how many ground crew members must be trained in aerial rescue for every climber working aloft?

Accepted Answer

At least one ground worker trained and capable of performing aerial rescue

Answer

Having at least one trained rescuer on the ground ensures immediate response if the climber is incapacitated without waiting for emergency services.

Question 3

What is a 'pick-off rescue' in tree climbing?

Accepted Answer

A second climber ascends to the stricken climber and assists or lowers them to the ground

Answer

The pick-off method is the most common aerial rescue technique and requires a second, trained climber and a lowering device.

Question 4

Why is suspension trauma a serious concern when a climber is left hanging unconscious in a harness?

Accepted Answer

Blood pools in the legs and can cause cardiac arrest when circulation is restored upon lowering

Answer

Orthostatic intolerance from prolonged suspension causes venous pooling; sudden restoration of circulation can trigger fatal cardiac arrest—known as 'rescue death.'

Question 5

What rescue equipment must be on site during every aerial tree operation?

Accepted Answer

A second climbing system, a descent device, and first aid supplies including a trauma kit

Answer

ANSI Z133 requires equipment capable of reaching and lowering an incapacitated climber, which means a functional second climbing system and lowering device must be present.
