What is the minimum safe working distance from overhead power lines for an arborist using non-insulated equipment?
Answer: 10 feet
OSHA requires a minimum clearance of 10 feet from power lines for unqualified workers using non-insulated equipment. Greater distances may be required for higher voltages.
Before starting any tree work, what is the first step in a job hazard assessment?
Answer: Conducting a 360-degree walk-around inspection of the tree and site
A 360-degree walk-around identifies hazards including dead branches, power lines, decay, lean direction, target zones, and ground conditions before any work begins.
When operating a chainsaw, what personal protective equipment (PPE) is required?
Answer: Hard hat, eye protection, hearing protection, chainsaw chaps or pants, and boots
Complete chainsaw PPE includes a hard hat with face screen, eye protection, hearing protection, cut-resistant chainsaw chaps or pants, and steel-toed/chainsaw-resistant boots.
What is the 'two-tie' or 'two-point' rule in tree climbing?
Answer: The climber must be secured by two independent attachment points at all times
The two-point rule requires climbers to maintain two independent points of attachment to the tree whenever possible, so that failure of one doesn't result in a fall.
What is a 'drop zone' and who is responsible for maintaining it?
Answer: The area below where branches and debris will fall; the ground crew
The drop zone is the area where cut material will fall. The ground crew is responsible for keeping this area clear of workers, pedestrians, and obstacles.
Why must arborists never work alone when performing aerial tree work?
Answer: A ground person is needed for emergency rescue if the climber is injured or trapped
A ground person trained in aerial rescue is essential. If a climber becomes injured, unconscious, or entangled, immediate rescue by a trained colleague can be life-saving.
