CTSP Chainsaw Use and PPE 4

Question 1

What chainsaw maintenance task must be performed every time the chain is sharpened?

Accepted Answer

Check and adjust the depth gauge (raker) height

Answer

Depth gauges must be checked and filed down periodically as the cutters are sharpened, because if gauges become too tall relative to cutters, cutting efficiency drops and kickback risk can increase.

Question 2

According to ANSI Z133, what is the minimum distance ground workers must maintain from a felling tree's potential strike zone?

Accepted Answer

Twice the tree's height

Answer

ANSI Z133 requires bystanders to be at least twice the tree's height away from the felling zone to account for bounce, roll, and unexpected fall direction.

Question 3

Chainsaw-resistant gloves (cut-resistant) protect against incidental contact but are NOT designed to stop a direct:

Accepted Answer

Full-speed chainsaw blade contact

Answer

Cut-resistant gloves provide protection against incidental chain contact and abrasions but cannot stop a direct, full-speed chainsaw cut — they are supplemental protection only.

Question 4

The OSHA Hazard Communication standard (29 CFR 1910.1200) applies to chainsaw fuel because bar-and-chain oil and gasoline mixtures are:

Accepted Answer

Hazardous chemicals requiring SDS documentation

Answer

Fuels and lubricants are hazardous chemicals under HazCom, requiring Safety Data Sheets (SDS) and proper labeling wherever they are used or stored.

Question 5

When operating a chainsaw on a slope, the arborist should position themselves:

Accepted Answer

To the side and slightly uphill

Answer

Standing to the side and slightly uphill keeps the operator out of the path of a rolling log or kickback while maintaining stable footing.
