Question 1

When rigging a large limb for removal, which rigging point placement best reduces the risk of the limb swinging back and striking workers?

Accepted Answer

Attach the rigging above the limb's center of gravity

Answer

Rigging above the limb's center of gravity keeps the load balanced and prevents uncontrolled swinging that could strike workers.

Question 2

A climber is working in a tree near a road. Which measure is MOST effective in protecting passing motorists from struck-by hazards?

Accepted Answer

Posting a flagger and using proper traffic control devices

Answer

ANSI Z133 requires proper traffic control including flaggers and devices that meet MUTCD standards when working near roadways.

Question 3

What is the primary purpose of establishing a 'drop zone' during aerial tree work?

Accepted Answer

To designate a controlled area where cut material will land, keeping it clear of personnel

Answer

A drop zone is a predetermined, clearly communicated, and personnel-free area where cut material is directed to land safely.

Question 4

Which factor most significantly increases the danger of a struck-by injury from a thrown chain during chainsaw kickback?

Accepted Answer

Operating the saw above shoulder height

Answer

Operating a chainsaw above shoulder height places the kickback zone closer to the operator's face and increases the severity of any chain contact.

Question 5

During a tree removal in a confined space, a co-worker is struck by a small piece of wood ejected from the chipper. What does this incident MOST likely indicate?

Accepted Answer

The operator fed material into the chipper while a co-worker was within the danger zone

Answer

Chipper struck-by incidents most commonly occur when personnel enter the infeed danger zone or when material is fed while others are nearby.
