About the TTT-2 Exam
The National Wireless Safety Alliance (NWSA) Telecommunications Tower Technician
Level 2 (TTT-2) certification exam is designed for technicians who perform intermediate-
level rigging, rescue, and installation tasks independently and can supervise Level 1
technicians .
Exam Domains & Weighting :
Domain Weight
Safety and Health (RF, Electrical, LOTO, PPE) 30-35%
Hoisting Equipment and Rigging 20-25%
Tower Structures 15-20%
Installation, Maintenance, and Modification 15-20%
Climbing, Rescue, and Fall Protection 10-15%
Key Updates: As of 2026, exam content reflects the revised ANSI/ASSP A10.48-2023
standard . The practical exam includes five main tasks: PPE inspection, capstan hoist
setup, hoisting with trolley/tag and heel block systems, and guy wire component
selection/installation .
Section 1: Safety and Health (Questions 1-45)
1. The primary difference between a TT1 and a TT2 technician is the TT2 technician's
ability to:
A) Perform basic climbing only
B) Work under direct supervision at all times
C) Perform intermediate rigging, rescue, and installation tasks independently
D) Only conduct ground operations
Answer: C
, TT2 certification focuses on intermediate-level skills, including independent rigging, rescue,
and installation responsibilities beyond entry-level TT1 work. TT2 technicians can also
supervise TTT-1 trainees .
2. Before ascending a tower, a TT2 technician must first verify:
A) Weather forecast for the next week
B) Client billing approval
C) Site-specific safety and rescue plan
D) Availability of replacement antennas
Answer: C
A site-specific safety and rescue plan is required to address hazards, access, and
emergency procedures before work begins .
3. When using a controlled descent device for rescue, the technician must ensure:
A) The device is rated for single-person loads only
B) The device is compatible with rope diameter and load rating
C) The rope is dry and unused
D) The device is attached below the victim
Answer: B
Descent devices must be compatible with the rope and rated for the combined load
(rescuer + victim) to ensure safe controlled lowering .
4. The primary purpose of a double lanyard system is to:
A) Increase comfort while climbing
B) Allow continuous 100% tie-off when moving around obstacles
C) Reduce the number of connection points needed
D) Provide backup in case the primary lanyard fails
Answer: B
A double lanyard (dual lanyard) allows the climber to remain attached at all times while
moving past intermediate anchors, maintaining 100% tie-off .
5. RF exposure awareness is important because:
A) RF energy always causes immediate injury
B) Excessive RF exposure can cause thermal and biological effects
,C) RF only affects equipment, not people
D) RF exposure is only a concern indoors
Answer: B
Excessive RF exposure can cause heating of body tissues (thermal effects) and potential
biological effects, particularly to skin and eyes .
6. When inspecting a harness, cuts or fraying in webbing indicate:
A) Normal wear
B) Cosmetic damage only
C) The harness must be removed from service
D) The harness can be repaired with tape
Answer: C
Any damage to webbing (cuts, fraying, burns, chemical damage) compromises fall
protection and requires immediate removal from service .
7. Weather conditions that require stopping tower work include:
A) Light clouds
B) Moderate temperatures
C) Lightning within the area
D) Overcast skies
Answer: C
Lightning presents an extreme hazard to tower workers due to height and conductivity.
Work must stop immediately when lightning is in the area .
8. The minimum approach distance to energized power lines is determined by:
A) Tower height
B) Weather conditions only
C) Voltage of the power line
D) Type of antenna being installed
Answer: C
Minimum approach distance is based on voltage to prevent arcing and electrocution risks.
Higher voltage requires greater clearance .
9. LOTO stands for:
, A) Load On Take Off
B) Lock Out Tag Out
C) Lower Outer Tower Opening
D) Line Out Tag Out
Answer: B
LOTO stands for Lock Out Tag Out, a safety procedure to isolate energy sources and
prevent accidental energization during maintenance .
10. On a job site, who can signal the crane operator to stop?
A) Only the foreman
B) Only the certified signal person
C) Anyone on the crew
D) Only the crane operator
Answer: C
Any worker who observes an unsafe condition can signal the crane operator to stop
immediately .
11. PPE is an abbreviation for:
A) Personal Protective Equipment
B) Primary Power Equipment
C) Personnel Positioning Equipment
D) Portable Power Extension
Answer: A
PPE refers to Personal Protective Equipment such as hard hats, harnesses, gloves, and
safety glasses .
12. Which certified stamp is required on safety glasses?
A) ANSI Z87.1
B) OSHA 1910
C) ASTM F2413
D) ISO 9001
Answer: A
