CTSP CTSP Tree Climbing and Rigging Safety 5

Question 1

A climber is using a mechanical rope-grab ascender. At what point is it MOST dangerous to weight this device?

Accepted Answer

When the rope is kinked or folded back on itself at the device cam

Answer

A kinked or back-folded rope can prevent the ascender cam from seating properly, causing it to fail to grip under body weight.

Question 2

What is the purpose of a 'redirect' in a climbing system?

Accepted Answer

To change the direction of the climbing line to improve positioning or reduce swing potential

Answer

A redirect repositions the climbing line's angle of pull, improving the climber's body position and reducing dangerous pendulum swing potential.

Question 3

When inspecting a wire-core rigging sling before use, which defect requires the sling to be immediately removed from service?

Accepted Answer

Broken wire strands exceeding 10% of total wires in any rope lay

Answer

Broken wire strands exceeding 10% of total wires in any lay indicate significant structural degradation and the sling must be removed from service per industry standards.

Question 4

The ANSI Z133 standard requires that when working aloft, a climber must maintain a second point of attachment before cutting their primary tie-in. This practice is called:

Accepted Answer

Continuous attachment or the never-off-rope rule

Answer

The ANSI Z133 continuous attachment rule requires that at least one attachment point be maintained at all times, so the climber is never completely off rope.

Question 5

A ground worker is tailing a lowering line on a port-a-wrap. The piece being lowered suddenly drops faster than expected. The safest immediate action is to:

Accepted Answer

Add additional wraps to the port-a-wrap to increase friction and slow the descent

Answer

Adding wraps to the port-a-wrap increases friction to slow the load; releasing the rope creates an uncontrolled drop and staying in position maintains control.
