Introduction
This comprehensive assessment is designed to rigorously evaluate the knowledge and practical skills
of a Level 2 Tower Technician. The exam covers a wide array of critical topics, from advanced tower
hardware identification and complex rigging scenarios to strict adherence to OSHA, ANSI, and FCC
regulations. Candidates will demonstrate their competence through a series of multiple-choice and
scenario-based questions that emphasize real-world application and sound decision-making. Success
on this exam signifies a technician’s readiness to perform advanced duties safely and effectively,
ensuring structural integrity, personal safety, and regulatory compliance in the dynamic and
demanding field of tower maintenance and construction.
SECTION ONE: QUESTIONS 1-100
1. What is the primary purpose of a "dead-end" grip on a tower guy wire?
A. To provide a temporary attachment point for hoisting equipment.
B. To permanently terminate the guy wire at the anchor or tower.
C. To create a loop for attaching a turnbuckle.
D. To protect the wire from abrasion where it passes over a sheave.
🟢 B. To permanently terminate the guy wire at the anchor or tower.
🔴 Explanation: A dead-end grip, also known as a preformed dead-end, is specifically designed to
provide a permanent, full-strength termination for guy wires at their anchor points. Options A, C,
and D describe functions of other types of hardware like slings, thimbles, or chafe guards.
2. How often should a full-body harness be inspected according to ANSI/ASSE Z359 standards?
A. Annually.
B. Before each use.
,C. Weekly.
D. Only after a fall event.
🟢 B. Before each use.
🔴 Explanation: ANSI/ASSE Z359 standards mandate that a full-body harness must be inspected by
the user before each and every use to ensure it is free of wear, damage, or defects. While a formal
documented inspection is required annually, the pre-use check is the most critical.
3. A technician is about to climb a tower that has a transmitting antenna with a high Effective
Radiated Power (ERP). What is the FIRST action they should take before climbing?
A. Ensure their RF monitor is functioning and in alarm mode.
B. Request that the transmitter power be reduced or turned off.
C. Wear a full-body harness with a dielectric rating.
D. Use a hot-stick to measure the RF field strength.
🟢 B. Request that the transmitter power be reduced or turned off.
🔴 Explanation: The primary and most effective control for RF radiation exposure is to reduce the
source power. According to the hierarchy of controls, eliminating the hazard (by reducing power to
zero or a safe level) is the preferred first step before relying on administrative or PPE controls.
4. When performing a rescue from height, what is the maximum recommended time a
suspended worker should remain in a harness before experiencing serious orthostatic
intolerance?
A. 30 minutes.
B. 15 minutes.
C. 1 hour.
D. 5 minutes.
🟢 D. 5 minutes.
🔴 Explanation: Suspension trauma (orthostatic intolerance) can begin within 5-15 minutes. It is a
life-threatening condition where blood pools in the lower extremities. A prompt rescue, ideally
within 5 minutes, is crucial to prevent loss of consciousness or death.
5. Which type of load is experienced by a guy wire during a severe windstorm?
A. Live load.
B. Dead load.
C. Environmental load.
D. Impact load.
🟢 C. Environmental load.
🔴 Explanation: Environmental loads are forces from natural events such as wind, ice, and
earthquakes. While the wind load is a live load, in the context of tower design, it is classified as an
environmental load which is a type of transient or live load. 'Dead load' refers to the static weight
of the structure itself. 'Impact load' is sudden, like a dropped tool.
6. A turnbuckle is found to be severely corroded and the threads are no longer visible. What is
the appropriate course of action?
A. Wire brush the corrosion and apply anti-seize compound.
, B. Replace the turnbuckle with a new one of the same size and rating.
C. Use a large pipe wrench to force the threads until they move.
D. Weld a reinforcing bar to the turnbuckle frame for added strength.
🟢 B. Replace the turnbuckle with a new one of the same size and rating.
🔴 Explanation: Severe corrosion that obscures threads compromises the structural integrity of the
turnbuckle. It must be replaced. Repairing or forcibly moving corroded threads weakens the
hardware and is not an acceptable practice, as it could lead to catastrophic failure.
7. According to OSHA, what is the minimum breaking strength required for a vertical lifeline
used in a personal fall arrest system?
A. 3,500 lbs.
B. 5,000 lbs.
C. 10,000 lbs.
D. 15,000 lbs.
🟢 B. 5,000 lbs.
🔴 Explanation: OSHA regulation 1926.502(d) requires that vertical lifelines have a minimum
breaking strength of 5,000 pounds. This standard is in place to ensure the lifeline can withstand the
dynamic forces of a fall arrest.
8. When installing a new antenna, what is the most important factor in determining the torque
value for the bolts?
A. The size of the wrench being used.
B. The age of the antenna.
C. The manufacturer's specifications.
D. The experience of the technician.
🟢 C. The manufacturer's specifications.
🔴 Explanation: The correct torque for any fastener is specified by the manufacturer of the
equipment to ensure proper clamping force without over-stressing or stripping the threads. This is
critical for structural integrity and electrical performance.
9. What does the term "wind loading" refer to in tower engineering?
A. The total weight of the tower.
B. The force exerted by the wind on the tower and its appurtenances.
C. The noise generated by wind passing through the tower structure.
D. The speed at which the tower sways in the wind.
🟢 B. The force exerted by the wind on the tower and its appurtenances.
🔴 Explanation: Wind loading is a critical design parameter. It quantifies the dynamic force that
wind applies to the entire surface area of the tower, including antennas, cables, and other
equipment, which the structure must be able to withstand.
10. A co-worker is unresponsive and not breathing after an electrical shock. What is the FIRST
priority?
A. Check for a pulse.
B. Begin CPR immediately.
