What is the recommended protocol for working during an electrical storm?
Answer: Cease all tree operations and seek appropriate shelter immediately
All tree work must cease during electrical storms. Trees are natural lightning conductors, making any proximity to them extremely dangerous during thunderstorms.
What is the 'two-tie' rule in tree climbing operations?
Answer: A climber must be secured by at least two points of attachment when positioned in the tree
The two-tie rule requires that a climber be secured by at least two separate attachment points whenever they are positioned in the tree, ensuring redundancy if one tie point fails.
According to OSHA regulations, at what trunk diameter should a tree be considered too large for hand-felling without a detailed written plan?
Answer: No specific diameter threshold exists; all felling requires assessment
OSHA does not set a specific diameter threshold. Every tree felling operation requires a hazard assessment regardless of size, as factors beyond diameter affect safety.
What is the proper hand signal for 'stop' during crane-assisted tree removal?
Answer: One arm extended with a closed fist
The standard hand signal for 'stop' in crane operations is extending one arm with a closed fist. This is part of the universally recognized crane hand signal system used across industries.
When performing aerial rescue of an injured arborist, what is the first priority?
Answer: Assess the scene for hazards and ensure rescuer safety before approaching the victim
As with all emergency response, scene safety and rescuer safety must be established first. A rescuer who becomes a second victim doubles the emergency.
What is the purpose of a 'tailboard safety briefing' conducted before the start of each job?
Answer: To communicate the job plan, identified hazards, and safety measures to all crew members
A tailboard (or toolbox) safety briefing is held before each job to ensure all crew members understand the work plan, identified hazards, emergency procedures, and their individual roles.
