NWSA TTT-2 TELECOMMUNICATIONS TOWER
TECHNICIAN LEVEL 2 – PRACTICE QUESTIONS
AND ANSWERS | VERIFIED AND WELL
DETAILED ANSWERS PLUS RATIONALES |
EXAM PREP | STUDY GUIDE | PRACTICE TEST
1. Before beginning work on a telecommunications tower, the crew leader
conducts a Job Hazard Analysis (JHA). What is the primary purpose of the
JHA?
A. To estimate project completion time
B. To identify hazards and determine appropriate controls before work begins
C. To assign payroll codes to employees
D. To determine equipment ownership
CORRECT ANSWER: B. To identify hazards and determine appropriate controls
before work begins
RATIONALE: A Job Hazard Analysis is a systematic process for identifying
workplace hazards, assessing risks, and implementing controls before work
starts. It helps reduce injuries and ensures the crew understands site-specific
hazards.
2. During a pre-climb inspection, a technician discovers a damaged energy
absorber on a personal fall arrest lanyard. What is the most appropriate
action?
A. Wrap the damaged area with tape and continue working
B. Replace the damaged component before climbing
C. Use the lanyard only for positioning
D. Allow another technician to inspect it during the climb
CORRECT ANSWER: B. Replace the damaged component before climbing
RATIONALE: Any damaged fall protection equipment must be removed from
service immediately. Using defective equipment significantly increases the risk of
fall-related injuries.
,3. Which practice best minimizes dropped-object hazards while working at
elevation?
A. Carry as many tools as possible by hand
B. Store loose hardware in open pockets
C. Secure tools using approved tool tethers and maintain housekeeping
D. Throw unused materials to the ground after warning workers below
CORRECT ANSWER: C. Secure tools using approved tool tethers and maintain
housekeeping
RATIONALE: Tool tethering and proper housekeeping are effective methods for
preventing dropped objects, protecting both workers aloft and personnel on the
ground.
4. A technician notices changing weather conditions with lightning
approaching the worksite. What should the crew do first?
A. Continue working until rainfall begins
B. Finish the current installation before descending
C. Immediately suspend climbing operations and move to a safe location
D. Remain attached to the tower until instructed otherwise
CORRECT ANSWER: C. Immediately suspend climbing operations and move to a
safe location
RATIONALE: Lightning presents an immediate life-threatening hazard. Climbing
activities should cease immediately, and workers should move to a safe shelter.
5. Why is maintaining 100 percent tie-off important while climbing?
A. It reduces climbing fatigue.
B. It allows faster movement on the structure.
C. It ensures continuous fall protection throughout the climb.
D. It eliminates the need for rescue planning.
, CORRECT ANSWER: C. It ensures continuous fall protection throughout the
climb.
RATIONALE: Maintaining continuous attachment minimizes exposure to fall
hazards. Rescue planning remains necessary regardless of tie-off practices.
6. Which responsibility belongs to every member of the work crew?
A. Ignoring unsafe conditions until instructed otherwise
B. Reporting hazards and stopping work when an imminent danger exists
C. Approving engineering modifications
D. Performing annual structural inspections
CORRECT ANSWER: B. Reporting hazards and stopping work when an imminent
danger exists
RATIONALE:
Every worker shares responsibility for recognizing hazards,
communicating concerns, and stopping work when conditions present imminent
danger.
7. During lifting operations, why should personnel avoid standing beneath
suspended loads?
A. It improves communication.
B. It reduces lifting time.
C. It prevents exposure to falling objects if equipment fails.
D. It allows easier equipment inspection.
CORRECT ANSWER: C. It prevents exposure to falling objects if equipment fails.
RATIONALE: Suspended loads can fall unexpectedly due to equipment failure or
shifting loads. Exclusion zones protect personnel from serious injury.
8. A technician identifies corrosion affecting a structural connection. What is
the best course of action?
