What is the primary purpose of a safety culture in utility vegetation management?
To ensure all workers prioritize safe behaviors, hazard awareness, and risk reduction in every task.
What is the definition of a “critical risk” in utility line-clearance operations?
A risk likely to cause severe injury, fatality, or major system damage if not properly controlled.
Which of the following is not considered a critical risk in UVM work? A. Electrical contact B. Chainsaw operation C. Animal identification D. Traffic exposure
C. Animal identification
What is the Minimum Approach Distance (MAD)?
The closest a worker or tool may approach an energized conductor without additional protective measures.
What determines the specific MAD for a job?
System voltage, worker qualification level, and regulatory standards.
Who is allowed to work inside the MAD? A. Any ground worker B. Only qualified line-clearance arborists C. Anyone wearing PPE D. Anyone supervised by a foreman
B. Only qualified line-clearance arborists
What is the purpose of a job briefing?
To communicate hazards, procedures, controls, and emergency plans before work begins.
When must a job briefing be repeated or updated?
Whenever hazards change or new workers join the task.
What are the three steps of hazard identification?
Recognize hazards, assess risks, and implement controls.
Give examples of common site hazards in UVM.
Energized lines, unstable trees, traffic, slopes, wildlife, and severe weather.
Why is situational awareness vital?
Because job sites change rapidly and new hazards can appear without warning.
The leading cause of fatalities in line-clearance tree work is: A. Chainsaw cuts B. Electrocution C. Heat stress D. Falls
B. Electrocution
Define “energized conductor.”
Any conductor carrying current.
What three factors influence the severity of electrical injury?
Voltage, current, and duration of contact.
What is the purpose of grounding and bonding?
To prevent hazardous voltage buildup and reduce shock risk.
PPE is used when: A. Hazards are fully eliminated B. Controls can’t completely remove risk C. A worker is inexperienced D. Only during storms
B. Controls can’t completely remove risk
List the minimum PPE normally required for line-clearance.
Helmet, eye protection, hearing protection, leg protection, gloves, and proper footwear.
What is the purpose of a second observer?
To monitor electrical clearance and warn if unsafe proximity occurs.
When must electrical line-clearance work stop because of weather?
When lightning, high winds, or poor visibility make conditions unsafe.
What is an unintentional conductor?
An object that can unexpectedly conduct electricity, such as a branch or tool.
What is a major chainsaw safety concern near energized conductors?
Chainsaws can conduct electricity if they contact or approach energized lines.
Before starting a chainsaw, a worker must: A. Engage the chain brake B. Stabilize the saw C. Ensure the area is safe D. All of the above
D. All of the above
Why is communication essential during rigging operations?
To ensure coordinated movements and prevent contact with energized equipment.
What are key rigging planning steps near utilities?
Load assessment, anchor selection, predicting line-of-fall, and evaluating electrical hazards.
