CTSP Incident Prevention and Response 5

Question 1

Which investigation method focuses on understanding the sequence of events and decisions that led to an incident, rather than assigning blame?

Accepted Answer

Root cause analysis

Answer

Root cause analysis systematically traces an incident back to its underlying systemic failures to prevent recurrence.

Question 2

When a chainsaw operator experiences 'kickback,' the saw's bar tip rotates upward and toward the operator primarily because:

Accepted Answer

The upper quadrant of the bar tip contacts wood and the chain's rotational force is redirected

Answer

Kickback occurs when the rotating chain at the bar tip's upper quadrant contacts an object, converting chain energy into rapid rotational force toward the operator.

Question 3

An OSHA recordable injury in tree care is defined as one that results in:

Accepted Answer

Death, days away from work, restricted duty, medical treatment beyond first aid, or loss of consciousness

Answer

OSHA defines recordable injuries by specific criteria including fatalities, lost workdays, restricted duty, or treatment beyond basic first aid.

Question 4

A crew is felling a tree and the escape route becomes blocked by a fallen limb mid-cut. The operator should FIRST:

Accepted Answer

Stop cutting, secure the saw, and clear the escape route before continuing

Answer

A clear escape route is non-negotiable; work must stop to restore the route before any felling cut continues.

Question 5

Which personal protective equipment item is SPECIFICALLY designed to protect an arborist from chainsaw contact to the legs while working on the ground?

Accepted Answer

Chainsaw-protective chaps or pants

Answer

Chainsaw chaps or pants contain cut-resistant fibers that clog the chainsaw drive sprocket, stopping the chain upon contact with the legs.
