Question 1
A safety professional is reviewing a fall protection plan for a telecommunications tower. Which of the
following best describes the primary purpose of a certified anchor?
A) To provide a temporary attachment point for tool lanyards
B) To support a fall arrest system with a minimum load capacity of 3,000 lbs per attached worker
C) To act as a tie-off point for positioning only, not fall arrest
D) To replace the need for a deceleration device
Rationale: A certified anchor must be designed, installed, and used under the supervision of a qualified
person to support at least 5,000 lbs per attached worker or twice the maximum arrest force (typically
3,000 lbs minimum). Correct answer: B – Certified anchors for fall arrest require a minimum load
capacity of 3,000 lbs when certified by a qualified person; 5,000 lbs is for uncertified anchors.
Question 2
During a CUSP inspection, you find a damaged RF transmission line with exposed inner conductor.
What is the most immediate hazard?
A) Electrical shock from 120 VAC
B) RF burns and high-voltage RF shock
C) Structural collapse from cable tension loss
D) Chemical leakage from dielectric coolant
Rationale: Damaged RF transmission lines can carry high-power RF energy, leading to severe RF
burns and shock even at low voltages due to high-frequency currents. Correct answer: B
,Question 3
According to OSHA’s telecommunications standard (29 CFR 1910.268), what is the minimum
approach distance for an unqualified worker to an energized 500V overhead line?
A) 2 feet
B) 4 feet
C) 6 feet
D) 10 feet
Rationale: *1910.268(n)(11) requires unqualified workers to maintain a 10-foot clearance from
energized lines up to 50 kV; for 500V (below 300V, special rules apply, but under 50kV, it’s 10 ft).*
Correct answer: D
Question 4
What is the maximum free fall distance permitted when using a personal fall arrest system (PFAS) in a
telecommunications climb?
A) 2 feet
B) 6 feet
C) 10 feet
D) 12 feet
Rationale: OSHA 1926.502(d)(16)(iii) limits free fall to 6 feet or less for PFAS unless using a lanyard
with a deceleration device specifically designed for longer free falls. Correct answer: B
Question 5
A tower crew is using an RF awareness monitor. The monitor alarms at 6% of the Maximum
Permissible Exposure (MPE). What action is required?
A) Full evacuation of the site
B) Continue work but log the event
C) Implement an RF protection plan and reduce exposure
D) No action because 100% MPE is the limit
Rationale: Many RF safety programs require controls at a lower threshold (e.g., 6% or 10% of MPE)
to ensure no worker exceeds 100% MPE under real conditions. Alarms require protective measures.
Correct answer: C
,Question 6
Which of the following is a required component of a Competent Person’s tower inspection?
A) RF reading only
B) Climbing system inspection including bolts, welds, and corrosion
C) Environmental noise assessment
D) Ground resistance testing
Rationale: *The competent person must inspect the structural integrity of the tower, including bolts,
welds, corrosion, and climbing systems per industry standards (ANSI/ASSE A10.48).* Correct answer:
B
Question 7
What does the term “100% tie-off” mean in tower work?
A) Tie off only when climbing past an obstacle
B) Tie off 100% of the time when on the ground
C) Being attached to an approved anchor at all times when exposed to a fall
D) Using two lanyards but only attaching one
Rationale: *“100% tie-off” requires continuous protection while climbing, transitioning, and working
at heights, using dual lanyards or a climbing system.* Correct answer: C
Question 8
A worker receives an RF burn on the wrist. What is the most likely injury mechanism?
A) Contact with a DC power source
B) Arc flash from a lightning strike
C) Induced current from an energized antenna
D) Reflection from a glass fiber
Rationale: RF burns occur due to induced currents from touching ungrounded conductive objects near
high-power antennas. The wrist is a common entry point due to jewelry or skin contact. Correct
answer: C
, Question 9
Which deceleration device is required for a fall of more than 6 feet?
A) Shock-absorbing lanyard with max 3.5 ft deceleration
B) Self-retracting lifeline (SRL)
C) Rope grab on a static line
D) Lanyard without a shock absorber
Rationale: *SRLs limit free fall to 2 feet or less and can be used for longer fall clearances;
shock-absorbing lanyards require free fall under 6 feet total.* Correct answer: B
Question 10
In RF safety, the “controlled environment” (Occupational/Controlled) exposure limits apply to:
A) The general public
B) Workers aware of RF exposure and able to take protective action
C) Any person near a cellular tower
D) Only workers with RF monitors
Rationale: *FCC defines Occupational/Controlled limits for workers informed of RF risks and able to
implement controls; General Population limits are 5x stricter.* Correct answer: B
Question 11
What is the primary purpose of a climbing rest platform on a tower?
A) Tool storage
B) *Provide a point for 100% tie-off transition and fatigue relief*
C) Antenna mounting
D) RF shielding
Rationale: Rest platforms are designed for worker safety to transition fall arrest systems and reduce
fatigue during long climbs. Correct answer: B
Question 12
A CUSP-D candidate must demonstrate proficiency in:
A) Tower structural design
