  1. Which type of saw chain requires the sharpest filing angle and delivers the fastest cutting but is most prone to kickback?

    Answer: Full-chisel chain

    Full-chisel chains have square-cornered cutters that cut aggressively and quickly but are more susceptible to kickback compared to semi-chisel designs.

  2. Chainsaw chaps are rated by classes. Class 1 chaps protect against chain speeds up to:

    Answer: 1,650 ft/min

    ASTM Class 1 chainsaw chaps are designed to protect against chain speeds up to 1,650 feet per minute, suitable for lower-speed saws.

  3. What is the purpose of the chainsaw's throttle interlock?

    Answer: Prevents accidental acceleration unless the rear handle is fully gripped

    The throttle interlock requires the rear handle to be gripped before the throttle can be depressed, preventing accidental engagement if the saw is bumped.

  4. During aerial chainsaw work, ANSI Z133 requires a saw to be secured with a:

    Answer: Lanyard or holder while climbing and positioning

    ANSI Z133 requires chainsaws to be secured with a lanyard or tool holder when climbing or positioning in the tree to prevent dropped-tool hazards.

  5. The anti-vibration system on a chainsaw primarily reduces the risk of which occupational health condition?

    Answer: Hand-arm vibration syndrome (HAVS)

    Prolonged chainsaw use without anti-vibration damping causes hand-arm vibration syndrome (HAVS), a permanent vascular and neurological condition affecting the hands and arms.

  6. When a chainsaw stalls while the bar is pinched in a cut, the operator should FIRST:

    Answer: Shut off the saw before attempting to free the bar

    The saw must be shut off before any attempt to free a pinched bar to prevent chain movement and injury during the extraction effort.

  7. Which PPE item protects against chainsaw cuts to the face and is specifically required under ANSI Z133 for chainsaw operation?

    Answer: Full-face shield or face protection

    ANSI Z133 requires face protection (a full-face shield or equivalent) during chainsaw operations to guard against flying debris and chain contact.
