Experience the Quality With Free Arborist Exam Questions That Helps Candidates Pass

In risk assessment, a target refers to people, property, or infrastructure that could be harmed if a tree or limb fails. The other options are defects, not targets. ISA’s TRAQ framework emphasizes evaluating both defects and targets to determine risk levels.

Severe root decay in a high target-use area presents extreme risk, requiring removal or immediate mitigation. ISA TRAQ emphasizes high-risk response in public spaces.

ANSI Z133 mandates a 10-foot minimum approach distance for unqualified personnel near energized conductors up to 50 kV. This ensures arborist safety. ISA exam safety content heavily features electrical hazard awareness.

Shaving or slicing root balls cuts circling roots and encourages outward growth, preventing girdling. Root washing can damage roots, deep planting suffocates them, and fertilizer is unnecessary at planting. ISA exams emphasize root management at installation.

Container-grown trees generally have intact root systems and higher survival rates if roots are not pot-bound. Bare-root requires careful timing, while large-caliper stock struggles with establishment. ISA exams compare stock types for establishment success.
