CTSP Chainsaw Use and PPE 5

Question 1

What does the term 'bore cutting' (plunge cutting) require the operator to use to initiate the cut safely?

Accepted Answer

The lower portion of the bar, rocking into the cut

Answer

Bore cutting should be initiated using the lower quadrant of the bar nose, rocking the saw forward carefully to avoid the upper kickback zone during entry.

Question 2

Which factor has the GREATEST effect on increasing kickback risk?

Accepted Answer

Contact with the upper nose quadrant of the bar

Answer

Contact with the upper nose quadrant is the primary cause of kickback events because that zone causes the chain to catch and rapidly rotate the bar upward.

Question 3

Under hot working conditions, a tree care worker wearing chainsaw chaps and full PPE should be monitored for signs of:

Accepted Answer

Heat stress and heat stroke

Answer

Full chainsaw PPE significantly reduces the body's ability to dissipate heat, greatly increasing the risk of heat stress and heat stroke in warm conditions.

Question 4

The 'dead man's throttle' feature on a chainsaw means:

Accepted Answer

The throttle returns to idle when the trigger is released

Answer

The dead man's throttle (trigger interlock) returns the chainsaw to idle speed as soon as the operator releases the throttle trigger, reducing chain speed immediately.

Question 5

When selecting chainsaw bar length for a climbing operation, the ANSI Z133 guidance recommends:

Accepted Answer

The shortest bar appropriate for the task to limit kickback exposure

Answer

ANSI Z133 recommends using the shortest bar appropriate for the task, as shorter bars reduce kickback severity and are easier to control in confined aerial positions.
