CTSP Chainsaw Use and PPE Questions and Answers

Question 1

A ground worker is using a chainsaw to cut small-diameter branches on a brush pile.
The worker is wearing a helmet, safety glasses, and hearing protection, but is not wearing chainsaw chaps or pants.
According to the ANSI Z133 standard, what is the correct assessment of this situation?

Accepted Answer

The worker must immediately stop work and put on appropriate leg protection before resuming any chainsaw use on the ground.

Answer

The worker is permitted to continue as long as the chainsaw has a functioning chain brake and low-kickback chain.

Answer

The worker can continue without leg protection if they have documented advanced training in precision cutting techniques.

Answer

The worker is compliant, as leg protection is only required for felling or bucking large logs.

Question 2

An arborist needs to start their chainsaw to begin work. According to ANSI Z133 safety standards, which of the following is a prohibited starting method?

Accepted Answer

Drop-starting the saw by holding it with one hand and pulling the starter cord with the other, without bracing it.

Answer

Starting the saw on the ground with one foot on the rear handle's guard and a firm grip on the top handle.

Placing the rear handle of the saw between the thighs, firmly gripping the top handle, and pulling the starter cord.

Answer

Placing the saw on the ground and securing it with one knee while pulling the starter cord.

Question 5

During a routine equipment inspection, a CTSP notices that a chainsaw's chain catcher—the small tab located beneath the guide bar—is broken off. What is the primary safety function of this component?

Accepted Answer

It intercepts and deflects a broken or derailed chain, preventing it from striking the operator.

Answer

It helps guide the chain back onto the bar if it becomes slightly derailed.

Answer

It prevents the chain from making contact with the ground when the saw is set down.

Answer

It reduces the vibration transferred from the engine to the operator's hands.
