Section 1 – Fall Protection, Rescue & Climbing Safety (Q1–40)
1. According to OSHA and typical tower safety standards, at what height above a
lower level must fall protection be used on a communications tower?
A. 4 feet
B. 6 feet
C. 10 feet
D. 15 feet
OSHA requires fall protection at 10 feet or more for general industry, including tower work.
,2. Which component of a personal fall arrest system (PFAS) is designed to limit the
force on the body during a fall?
A. Lanyard only
B. Shock-absorbing lanyard or self-retracting lifeline (SRL)
C. Climbing belt only
D. Work positioning strap
Shock absorbers reduce arrest forces to survivable levels.
3. A technician is climbing a 250-foot lattice tower and must maintain 100% tie-off.
Which system is most appropriate?
A. Single lanyard with no climber
B. Dual-lanyard system with a climbing device or SRL
C. No fall protection until reaching the work area
D. Only a work positioning belt
Dual lanyards or approved climbing devices allow continuous tie-off.
4. Which of the following is the correct anchorage strength requirement for a
personal fall arrest system anchor point?
A. 1,000 lbs per worker
B. 3,000 lbs per worker
C. 5,000 lbs per worker, or designed by a qualified person with a safety factor of 2
D. 10,000 lbs per worker
OSHA requires 5,000-lb capacity or engineered equivalent.
5. A technician’s fall arrest harness shows frayed webbing and cracked D-rings. What
is the most appropriate action?
A. Use it for short climbs only
B. Remove it from service immediately and tag it “Do Not Use”
C. Repair it with duct tape
D. Use it only for work positioning
,Damaged PPE must be taken out of service.
6. Which of the following best describes “work positioning” on a tower?
A. Allowing a free fall of up to 6 feet
B. Using a system that supports the worker on an elevated vertical surface with
minimal free fall
C. Using only a ladder without fall protection
D. Working without any tie-off
Work positioning supports the worker hands-free with limited fall distance.
7. A rescue plan for tower work must be prepared:
A. Only after an incident occurs
B. Before work begins, and must be site-specific
C. Only for towers over 300 feet
D. Only if the client requests it
OSHA requires a rescue plan before work starts.
8. What is the maximum allowable free fall distance for a personal fall arrest system
under OSHA?
A. 2 feet
B. 4 feet
C. 6 feet
D. 10 feet
Maximum free fall is 6 feet for PFAS.
9. A technician is working on a small roof-top monopole. Which hazard must still be
considered for fall protection?
A. No hazard if under 10 feet
B. Fall hazard if any edge or opening is 10 feet or more above a lower level
, C. Only RF hazard
D. Only electrical hazard
Height above a lower level determines fall protection requirements.
10. Which of the following is the primary purpose of a tower climbing safety device
(e.g., rail or cable system)?
A. Hold tools
B. Provide continuous fall protection while climbing
C. Support body weight for work positioning only
D. Act as a radio ground
Climbing safety devices are engineered fall protection systems.
11. A technician is using a self-retracting lifeline (SRL). Which practice is correct?
A. Allow the SRL to hang loose and drag on the ground
B. Keep the SRL above the dorsal D-ring when possible and avoid sharp edges
C. Use it as a tow line for equipment
D. Share it with another climber at the same time
SRLs must be used per manufacturer instructions to avoid damage and excess fall
distance.
12. Which of the following is an acceptable method for rescuing an injured climber
from a tower?
A. Let them climb down on their own regardless of condition
B. Use a pre-planned rescue system (e.g., descent device, tag line, or trained rescue
team)
C. Cut their fall protection and lower them with a rope only
D. Wait for fire department without doing anything
Pre-planned, controlled rescue is required.
