NWSA TTT-2 EXAM 300 ACTUAL QUESTIONS AND
CORRECT ANSWERS WITH RATIONALE LATEST
UPDATE ALREADY GRADED A+
This comprehensive practice exam is meticulously designed to prepare candidates
for the rigorous NWSA Telecommunications Tower Technician 2 (TTT-2)
certification, thoroughly evaluating their advanced knowledge and practical skills
in tower climbing and telecommunications infrastructure. It covers all essential
domains including fall protection systems, tower rescue procedures, hoisting and
rigging operations, electrical safety and RF awareness, guy wire systems, tower
equipment installation, and supervisory leadership. The exam also assesses
understanding of safety regulations (ANSI/ASSP A10.48), emergency response
protocols, inspection and maintenance procedures, and communication systems.
Candidates must demonstrate proficiency in real-world tower work scenarios and
pass the accredited certification to qualify for the advanced Antenna and Line
Specialty (ALS) credential.
Section 1: Fall Protection Systems and PPE
1. According to industry standards, at what working height is fall protection
required?
A) 4 feet
B) 6 feet
C) 10 feet
D) 15 feet
Answer: B
Rationale: Fall protection is generally required at heights of 6 feet or more in
general industry and telecommunications, per OSHA construction standards .
2. What is the maximum arresting force allowed in the event of a fall?
A) 900 lbs
B) 1,800 lbs
C) 3,600 lbs
D) 5,000 lbs
Answer: B
,Rationale: The maximum arresting force on a worker in a fall is limited to 1,800
lbs under OSHA standards to prevent serious injury from the sudden deceleration .
3. A vertical lifeline must have a minimum breaking strength (MBS) of:
A) 2,500 lbs
B) 3,600 lbs
C) 5,000 lbs
D) 10,000 lbs
Answer: C
Rationale: Vertical lifelines must have a minimum breaking strength of 5,000 lbs
for fall protection per OSHA standards .
4. What does the term "free fall" refer to in fall protection?
A) The distance between anchor points
B) The distance between a fall occurring and the fall being arrested
C) A controlled descent using a belay device
D) Unrestrained movement on a flat roof
Answer: B
Rationale: Free fall is the period from the moment a fall begins until the fall
protection system stops the fall .
5. Fall restraint is defined as:
A) Arresting a fall after it occurs
B) Preventing a fall entirely
C) Stopping a fall within 6 inches
D) Slowing the rate of descent
Answer: B
Rationale: Fall restraint systems prevent a fall from occurring, rather than arresting
one after it has begun. This is different from fall arrest systems .
6. The standard cable size used on a safety climb system is:
A) 1/4 inch
B) 3/8 inch
C) 1/2 inch
D) 5/8 inch
Answer: B
Rationale: Safety climb systems typically use 3/8 inch diameter cable to work with
cable-grabbing fall arrest devices .
7. All carabiners used for fall protection must have a locking gate strength of:
,A) 1,800 lbs
B) 3,600 lbs
C) 5,000 lbs
D) 7,200 lbs
Answer: B
Rationale: Carabiners used in fall protection must have a minimum gate strength of
3,600 lbs to ensure they can withstand the forces of a fall .
8. What is the fall protection latch mechanism load rating?
A) 1,800 lbs
B) 3,600 lbs
C) 5,000 lbs
D) 7,200 lbs
Answer: B
Rationale: The fall protection latch mechanism is rated at 3,600 lbs, matching the
gate strength requirement for carabiners .
9. All connecting devices (lanyards, rope grabs, etc.) must be:
A) Manual locking and manual closing
B) Auto locking and auto closing
C) User-checked before each climb
D) Manufacturer-certified annually
Answer: B
Rationale: Connecting devices must be auto-locking and auto-closing to prevent
accidental opening during use .
10. The primary purpose of a double lanyard (dual 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
Rationale: A double lanyard allows the climber to remain attached at all times
(100% tie-off) while moving past intermediate anchors, maintaining continuous
fall protection .
11. When working on a rooftop site with no barricade or parapet wall, what can be
used to avoid falling over the edge?
A) Fall arrest system
B) Travel restraint system
, C) Positioning system
D) Rope grab
Answer: B
Rationale: Travel restraint systems prevent a fall from occurring by restricting
movement to safe areas, making them ideal for rooftop work without barriers .
12. What does the "three points of contact" rule accomplish?
A) Increases climbing speed
B) Distributes load across major muscles, reduces fatigue, and improves stability
C) Ensures the climber can reach the top faster
D) Prevents the need for fall protection
Answer: B
Rationale: Three points of contact distributes load across major muscles, reduces
fatigue, and improves stability during climbs .
13. OSHA requires a ______ Person on-site to oversee fall protection systems.
A) Competent
B) Qualified
C) Certified
D) Authorized
Answer: A
Rationale: OSHA requires a Competent Person on-site to oversee fall protection
systems, someone capable of identifying hazards and having authority to correct
them .
14. If a climber discovers a defect in their fall protection equipment, what should
they do?
A) Continue using it if the defect is small
B) Immediately remove it from service and report it
C) Use it anyway if the climb is short
D) Temporarily bypass it with a lanyard
Answer: B
Rationale: Defective fall protection equipment must be immediately removed from
service, tagged, and reported for repair or replacement .
15. What is the primary purpose of a full-body harness in fall protection?
A) Comfort during climbing
B) Distributing fall arrest forces across the body
C) Providing storage for tools
D) Allowing faster climbing speed
