CTSP Hazard Identification and Control 2

Question 1

When assessing a tree for work, which condition most strongly indicates the presence of internal decay?

Question 3

Which type of cut is most likely to create a reaction wood hazard that causes unexpected stem movement?

Accepted Answer

A top cut on a leaning stem under compression

Answer

Cutting a leaning stem under compression can release stored energy suddenly, causing the wood to kick back or spring unpredictably.

Question 4

According to ANSI Z133, the minimum safe approach distance from an energized conductor rated 50–200 kV for an unqualified worker is:

Accepted Answer

15 feet

Answer

ANSI Z133 requires unqualified workers to maintain a minimum 15-foot distance from conductors rated 50–200 kV.

Question 5

A tree's root plate is partially lifted on one side. This condition most directly indicates a hazard of:
