Graded A+ | 2026
Exam Overview:
The NWSA Telecommunications Tower Technician Level 2 (TTT-2) certification exam is a
comprehensive assessment for tower technicians performing intermediate-level work,
including independent rigging, rescue, and installation tasks beyond entry-level TT1
responsibilities . Successful completion requires passing a combination of a computer-
based written exam and a hands-on practical exam conducted in a real-world environment
using an actual tower and associated materials .
SECTION 1: SAFETY AND HEALTH (Questions 1-50)
Q1. The primary difference between a TT1 and a TT2 technician is the TT2
technician's ability to:
Answer: Perform intermediate rigging, rescue, and installation tasks independently.
Rationale: TT2 certification focuses on intermediate-level skills, including independent
rigging, rescue, and installation responsibilities beyond entry-level TT1 work .
Q2. Before ascending a tower, a TT2 technician must first verify:
Answer: A site-specific safety and rescue plan.
Rationale: A site-specific safety and rescue plan is required to address hazards, access,
and emergency procedures before work begins .
,Q3. A tower technician arrives at a site and discovers wind speeds exceeding the
company climbing limit. What should the technician do FIRST?
Answer: Delay climbing operations until conditions improve.
Rationale: Safety policies prohibit climbing during unsafe weather conditions. Continuing to
climb would violate safety protocols .
Q4. What is the PRIMARY purpose of a fall arrest system?
Answer: Stop a fall safely and minimize injury.
Rationale: Fall arrest systems protect workers from fatal falls. The purpose is to safely
arrest a fall, not to increase speed or secure equipment .
Q5. A technician notices corrosion on a tower anchor bolt. What is the BEST action?
Answer: Report and document the issue immediately.
Rationale: Structural defects must be documented and evaluated. Corrosion can
compromise structural integrity and should not be ignored or painted over .
Q6. Before climbing, technicians should inspect:
Answer: All PPE and climbing equipment.
Rationale: Complete equipment inspection is required before climbing. This includes
harnesses, lanyards, and all climbing equipment .
Q7. A technician drops a wrench from 200 feet. Which safety practice would MOST
likely have prevented this?
Answer: Tool tethering.
Rationale: Tool lanyards prevent falling object hazards. Tethered tools reduce the risk of
dropped objects causing injury below .
,Q8. What is the PRIMARY hazard of RF exposure?
Answer: Tissue heating and burns.
Rationale: RF energy can cause thermal injury to body tissues. Excessive RF exposure
can cause heating of body tissues, particularly the skin and eyes .
Q9. A crew prepares to hoist an antenna. What is the FIRST step?
Answer: Conduct pre-lift meeting and equipment inspection.
Rationale: Before any lifting operation, the crew must conduct a pre-lift meeting and inspect
all equipment to ensure safety .
Q10. A technician observes a coworker climbing without a double lanyard. What
should the technician do?
Answer: Immediately warn the coworker and, if necessary, report the unsafe act to
supervision.
Rationale: Free climbing is prohibited. Workers must remain continuously attached while
climbing. Unprotected exposure at height is extremely dangerous .
Q11. What is the primary benefit of climbing with three points of contact?
Answer: Reduces the risk of falls during ascent.
Rationale: Three points of contact distributes load across major muscles, reduces fatigue,
and improves stability during climbing .
Q12. A worker identifies ice accumulation on tower members. What is the BEST
action?
Answer: Suspend climbing operations.
, Rationale: Ice creates severe slip and falling hazards. Operations should be suspended
until the ice clears .
Q13. Which document outlines site-specific hazards and procedures?
Answer: Job Hazard Analysis (JHA).
Rationale: A JHA identifies risks and controls for the specific site and scope of work .
Q14. What is the PRIMARY danger of dropped objects on tower sites?
Answer: Serious injury or death below.
Rationale: Falling objects are major hazards at height. Exclusion zones below lifts protect
personnel from falling objects and load movement .
Q15. A technician discovers damaged stitching on a harness. What is the correct
action?
Answer: Remove harness from service immediately.
Rationale: Damaged fall protection equipment must not be used. Any damage to webbing
(cuts, fraying, burns, chemical damage) compromises fall protection .
Q16. Which communication practice improves lifting safety?
Answer: Clear designated signal person.
Rationale: Consistent communication prevents lifting accidents. A designated signal person
ensures clear, unambiguous commands .
Q17. A technician working near energized lines should FIRST:
Answer: Identify and maintain required approach distances.
Rationale: Electrical contact hazards can be fatal. Minimum approach distance is based on
voltage to prevent arcing and electrocution risks .
