Which type of aerial lift is specifically designed for tree care work and allows 360-degree continuous rotation?
Answer: Articulating knuckle boom with continuous rotation
Articulating knuckle booms with continuous rotation are preferred in tree care because they allow full access around a tree without repositioning the truck.
Before entering the aerial lift work zone, what must a tree care crew establish?
Answer: A hazard communication plan and designated drop zone with cones or flagging
Establishing a defined drop zone with visible barriers and a hazard communication plan protects ground crew and the public from aerial hazards.
What is the primary purpose of the boom's load moment indicator (LMI) or capacity chart on an aerial lift?
Answer: To warn the operator when the load and reach combination approaches the machine's tip-over limit
The LMI or capacity chart tells operators the safe load limits at various boom angles and extensions to prevent tip-over caused by exceeding stability limits.
A worker in an aerial lift bucket is struck by a falling branch and becomes unresponsive. The ground crew's first action should be:
Answer: Activate the ground controls to lower the bucket immediately
The ground crew must use the emergency ground controls to lower the incapacitated worker to safety as quickly and carefully as possible.
Which hazard is unique to aerial lift operations compared to conventional tree climbing?
Answer: Tip-over of the support equipment
Tip-over of the truck itself is a hazard specific to aerial lift operations that tree climbers do not face; improper setup or slope can cause catastrophic vehicle overturn.
How often must aerial lift operators receive formal training per OSHA and ANSI standards?
Answer: Every 3 years and whenever an operator is observed operating unsafely
OSHA 1910.67 and ANSI A92.2 require retraining every 3 years and immediately whenever an operator demonstrates unsafe behavior or is assigned a different equipment type.
What is the minimum safe approach distance for an unqualified worker operating an aerial lift near 7,200-volt distribution lines?
Answer: 10 feet
OSHA Table S-5 requires a minimum approach distance of 10 feet for voltages up to 50 kV for unqualified workers using aerial equipment.
