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

    Answer: Check and adjust the depth gauge (raker) height

    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.

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

    Answer: Twice the tree's height

    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.

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

    Answer: Full-speed chainsaw blade contact

    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.

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

    Answer: Hazardous chemicals requiring SDS documentation

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

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

    Answer: To the side and slightly uphill

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

  6. What is 'reactive forces' in chainsaw terminology?

    Answer: Forces including kickback, pushback, and pull-in that can cause loss of control

    Reactive forces — kickback (upward rotation), pushback (saw thrust backward), and pull-in (saw pulled forward) — are the three dangerous force reactions that can cause the operator to lose control.

  7. Chainsaw PPE boots should meet which standard for cut protection?

    Answer: ASTM F2413 with cut-resistant protection

    Chainsaw-protective boots must meet ASTM F2413 with the appropriate cut-resistance rating to protect against accidental chainsaw contact to the foot.
