Introduction
*This comprehensive examination is designed to assess the knowledge and applied skills required for the NWSA
Tower Technician Training – Level 2 (TTT-2) certification. Candidates will demonstrate proficiency in advanced
tower safety, fall protection systems, RF hazard awareness, rescue procedures, structural hardware identification,
rigging techniques, and regulatory compliance. Questions include multiple‑choice and scenario‑based items
,that emphasize real‑world decision‑making, risk assessment, and proper execution of climbing and rescue
operations. Successful completion verifies that a technician can work independently and lead tasks at height
while maintaining the highest safety and ethical standards.*
SECTION ONE: QUESTIONS 1 – 100
Question 1
Which of the following is the primary purpose of a pre‑climb hazard assessment?
A. To satisfy documentation requirements for the site owner
B. To identify potential risks and determine necessary controls before ascending
C. To assign blame in the event of an accident
D. To estimate the time needed for tower maintenance
🟢B
🔴 RATIONALE: The primary purpose of a pre‑climb hazard assessment is to proactively identify hazards (e.g.,
weather, structural damage, RF energy) and implement controls to prevent injury. Documentation is secondary,
and assigning blame is never a goal.
,Question 2
A technician notices a worn section of their full‑body harness webbing. What is the correct action?
A. Continue using it if the wear is less than 50% of the width
B. Repair the webbing with heavy‑duty stitching
C. Immediately remove the harness from service and destroy it
D. Wrap the worn area with electrical tape as a temporary fix
🟢C
🔴 RATIONALE: Damaged or worn webbing must be immediately removed from service and destroyed to
prevent inadvertent reuse. Repair is not permitted, and temporary fixes are unacceptable for fall protection
equipment.
Question 3
According to OSHA, what is the maximum free fall distance permitted when using a personal fall arrest system
(PFAS)?
A. 2 feet
B. 4 feet
C. 6 feet
D. 12 feet
🟢C
🔴 RATIONALE: OSHA 1926.502(d)(16)(iii) limits free fall to 6 feet or less for personal fall arrest systems to
reduce arrest forces and prevent injury.
, Question 4
During a tower climb, you hear a sudden increase in RF power warning from the site controller. You have not yet
reached the first safe zone. What should you do?
A. Continue climbing quickly to reach the safe zone faster
B. Descend immediately to ground level
C. Stop climbing and maintain position until the RF level drops
D. Call the site manager and ask for permission to continue
🟢B
🔴 RATIONALE: An unexpected increase in RF power requires immediate descent to a safe RF level (usually
ground), as remaining at height could result in over‑exposure. Do not wait or continue upward.
Question 5
Which type of antenna typically presents the highest RF exposure hazard to a climbing technician?
A. Omni‑directional broadcast antenna
B. Parabolic (dish) antenna
C. Panel antenna
D. Yagi antenna
🟢B
🔴 RATIONALE: Parabolic dish antennas focus RF energy into a narrow beam, creating very high power density
