CTSP CTSP Tree Climbing and Rigging Safety 2 — Questions and Answers
Question 1: How frequently must climbing equipment be inspected according to ANSI Z133 best practices?
- Monthly by a qualified arborist
- Weekly by the crew supervisor
- Before each use by the climber (Correct answer)
- Annually by the equipment manufacturer
Correct answer: Before each use by the climber
Climbing equipment must be inspected before each use to identify wear, damage, or defects that could compromise safety.
Question 2: What is the purpose of a redirect in a tree climbing system?
- To lower cut limbs to the ground crew
- To change the direction of the climbing line to improve the climber's position (Correct answer)
- To tie off the climbing line to a ground anchor point
- To increase the mechanical advantage of the rigging setup
Correct answer: To change the direction of the climbing line to improve the climber's position
A redirect changes the direction of the climbing line, allowing the climber to maneuver more effectively and safely within the canopy.
Question 3: Per ANSI Z133, why is a secondary attachment system required for all tree climbing operations?
- It is required only for climbs above 30 feet
- So that if the primary attachment fails the climber is still protected from a fall (Correct answer)
- To meet OSHA electrical safety requirements
- It is recommended but not required by ANSI Z133
Correct answer: So that if the primary attachment fails the climber is still protected from a fall
ANSI Z133 mandates a secondary attachment to provide redundancy so that failure of the primary system does not result in a fall.
Question 4: Weight ratings for climbing saddles used in tree care are determined by which of the following?
- OSHA 1910 standards for fall protection
- ANSI Z133 universal rating of 300 lbs
- The specific manufacturer's stated capacity for that model (Correct answer)
- The climber's body weight only, not including tools
Correct answer: The specific manufacturer's stated capacity for that model
Weight ratings for climbing saddles vary by model and must be determined from the manufacturer's specifications for that specific equipment.
Question 5: What does 'body-to-work' positioning describe in tree climbing practice?
- Working only from the ground for safety
- Positioning so the work is between the climber and the attachment point (Correct answer)
- Using the climber's body weight as a counterweight during rigging
- Orienting the chainsaw body away from the climber at all times
Correct answer: Positioning so the work is between the climber and the attachment point
'Body-to-work' means positioning the work between the climber and their attachment point, providing maximum stability and control.
Question 6: What is the minimum number of full wraps typically required when tying a Prusik knot for climbing use?
- 1 full wrap
- 2 full wraps
- 3 full wraps (Correct answer)
- 5 full wraps
Correct answer: 3 full wraps
A Prusik knot requires a minimum of 3 full wraps to generate sufficient friction for reliable climbing use.
