  1. ANSI Z133 is the primary safety standard governing which type of work?

    Answer: Arboricultural operations

    ANSI Z133 is the American National Standard for Arboricultural Operations — Safety Requirements, covering climbing, aerial lifts, and ground operations.

  2. When using a chainsaw in a tree, the operator must ensure the chain brake is functional primarily to protect against:

    Answer: Bar tip contact causing kickback

    The chain brake is designed to stop the chain instantly if kickback occurs, most commonly caused by contact with the upper tip (kickback zone) of the bar.

  3. Under ANSI Z133, what minimum distance must workers maintain from energized power lines when using aerial lift equipment rated under 46 kV?

    Answer: 10 feet

    ANSI Z133 requires a minimum approach distance of 10 feet from energized conductors up to 50 kV when using aerial lift equipment.

  4. A work zone for tree removal on a public street should be established using traffic control measures that comply with which document?

    Answer: MUTCD (Manual on Uniform Traffic Control Devices)

    The MUTCD sets the national standard for traffic control devices and work zone setup on public roadways.

  5. Which Personal Protective Equipment (PPE) is specifically required by ANSI Z133 when operating a chainsaw on the ground?

    Answer: Cut-resistant leg protection (chainsaw chaps or pants)

    ANSI Z133 mandates cut-resistant leg protection such as chaps or chainsaw pants whenever a chainsaw is operated on the ground.

  6. Before beginning any tree work near an electrical utility line, the arborist's FIRST action should be to:

    Answer: Contact the utility company to identify line voltage

    Identifying line voltage by contacting the utility is the essential first step before determining safe approach distances and required PPE.

  7. The term 'qualified line-clearance arborist' under ANSI Z133 refers to a worker who:

    Answer: Has been trained and authorized to work within the minimum approach distance of energized conductors

    A qualified line-clearance arborist is specifically trained and authorized by their employer to work within the established minimum approach distances of energized lines.
