CTSP Hazard Identification and Control 4

Question 1

A tree assessment reveals a basal cavity that occupies more than one-third of the trunk's circumference. The most appropriate risk management action is:

Accepted Answer

Remove or significantly reduce the tree after confirming no internal sound wood remains

Answer

A basal cavity exceeding one-third of the trunk circumference typically indicates insufficient residual wall thickness to support the tree safely, often warranting removal.

Question 2

Which of the following actions BEST demonstrates the hierarchy of hazard controls in arboricultural work?

Accepted Answer

Eliminating the hazard by removing the dead branch before beginning aerial work

Answer

Elimination is the highest level of hazard control in the hierarchy, and removing the hazardous branch before work is the strongest control available.

Question 3

What does a 'confined space' designation mean for a tree worker operating near a utility vault or below-grade structure?

Accepted Answer

Entry requires specific permits, atmospheric testing, and rescue capability

Answer

Permit-required confined spaces demand atmospheric testing, a confined space entry permit, and an emergency rescue plan before any worker enters.

Question 4

During aerial work in a tree, a climber notices the branch she is attached to has significant bark inclusion. She should:

Accepted Answer

Shift her tie-in point to a structurally sound branch before proceeding

Answer

A climber must relocate her tie-in point to a sound anchor when a structural defect is discovered, as a branch with included bark may fail under load.

Question 5

What is the role of a spotter during mechanical equipment operations in a tree crew?

Accepted Answer

To watch for overhead hazards and direct the equipment operator via clear signals

Answer

A spotter watches for hazards the equipment operator cannot see—especially overhead—and communicates using pre-established signals to prevent collisions and accidents.
