NWSA Telecommunications Tower Technician 1 (TTT-1) — Questions and Answers

Question 1: What PPE is required as a minimum for all workers at a tower work site?

Only a hard hat
Hard hat, safety glasses, high-visibility vest, and work boots with appropriate soles (Correct answer)
Steel-toed boots only
No PPE is required on the ground

Correct answer: Hard hat, safety glasses, high-visibility vest, and work boots with appropriate soles

Minimum site PPE protects against falling objects, eye hazards, visibility to equipment operators, and foot injuries.

Question 2: How should a foreman handle a crew member who refuses to follow safety procedures?

Wait until the end of the day to discuss it
Address the behavior immediately, document the incident, and remove the worker from hazardous work if they continue (Correct answer)
Let other crew members handle it
Ignore it if the worker is experienced

Correct answer: Address the behavior immediately, document the incident, and remove the worker from hazardous work if they continue

Immediate correction is essential because unsafe behavior puts the entire crew at risk.

Question 3: What are the three main types of telecommunications tower structures?

Wood, plastic, and concrete
Single-pole, double-pole, and triple-pole
Self-supporting lattice, guyed, and monopole (Correct answer)
Residential, commercial, and industrial

Correct answer: Self-supporting lattice, guyed, and monopole

Self-supporting lattice towers use a wide base for stability, guyed towers use wire supports, and monopoles are single tubular structures.

Question 4: What is the primary function of a Material Safety Data Sheet (MSDS)?

To schedule maintenance checks
To list employee contact information
To provide information on the safe use of chemicals (Correct answer)
To document daily work activities

Correct answer: To provide information on the safe use of chemicals

An MSDS provides detailed information on the properties of chemical products, including handling, storage, and emergency measures.

Question 5: When working at height in conditions below freezing, which adaptation to PPE is most important for maintaining safety?

Relying on body heat to compensate and using standard PPE unchanged
Wearing thicker gloves without regard to dexterity loss
Removing the hard hat to wear a winter hat underneath without re-checking fit
Using thermal inner layers under the harness and ensuring harness fit is re-checked after layering (Correct answer)

Correct answer: Using thermal inner layers under the harness and ensuring harness fit is re-checked after layering

Wearing thermal layers under a harness can change its fit and adjustment; workers must re-check and re-adjust harness fit over cold-weather clothing to ensure it remains snug and effective.

Question 6: A tower technician is tasked with weatherproofing a newly installed N-type connector on an antenna jumper. Which of the following describes the proper layering sequence for maximum protection?

A single layer of UV-resistant electrical tape.
Two layers of butyl rubber tape with no outer covering.
A primary wrap of butyl rubber tape followed by an outer wrap of UV-resistant electrical tape. (Correct answer)
An initial wrap of electrical tape, followed by butyl rubber tape.

Correct answer: A primary wrap of butyl rubber tape followed by an outer wrap of UV-resistant electrical tape.

The industry-standard method for weatherproofing RF connectors involves a two-stage process. First, a layer of butyl rubber (or similar self-fusing/mastic) tape is stretched and wrapped to create a watertight seal. This is followed by a protective outer layer of high-quality, UV-resistant electrical tape to shield the butyl from sunlight and physical abrasion.

Question 7: During an inspection of a monopole, a technician ensures the small opening at the base of each slip joint is clear of debris. What is the primary purpose of this component, known as a weep hole?

To provide a lifting point for maintenance activities.
To allow for the attachment of grounding conductors.
To permit the drainage of internal condensation and moisture. (Correct answer)
To verify the proper overlap distance of the sections.

Correct answer: To permit the drainage of internal condensation and moisture.

Weep holes are designed to allow any moisture that accumulates inside the hollow sections of a monopole to drain out. This prevents the buildup of water which can lead to internal corrosion and damage from freeze/thaw cycles.

Question 8: While performing a hands-on inspection of a guy wire, a technician discovers two broken wires within a single strand lay length. What is the generally accepted course of action according to industry standards?

Immediately report the condition for engineering review and likely replacement. (Correct answer)
Apply a serving wire over the break as a temporary repair.
Clean and lubricate the area to prevent further breakage.
Note the finding for monitoring during the next inspection cycle.

Correct answer: Immediately report the condition for engineering review and likely replacement.

Most standards and best practices for wire rope and guy strand inspection state that finding two or more broken wires in one lay length is cause for immediate removal from service or replacement. This condition significantly compromises the strength and safety of the guy wire.

Question 9: What is the primary purpose of a hoisting grip when lifting transmission lines?

To serve as the primary, permanent support for the cable's weight after installation.
To provide a permanent grounding point for the cable.
To safely distribute the pulling force over a section of the cable without causing damage. (Correct answer)
To protect the connector from damage during the lift.

Correct answer: To safely distribute the pulling force over a section of the cable without causing damage.

A hoisting grip is a woven mesh device that tightens around the cable as tension is applied. Its purpose is to distribute the load of the cable's weight over a large surface area during the hoist, preventing kinks, dents, or other damage that would occur if the cable were pulled by a single point.

Question 10: What documentation should be produced after completing a tower structural inspection?

A verbal summary to the tower owner is sufficient
Only a pass/fail determination
Documentation is only needed if problems are found
A written report with photographs, deficiency ratings, measurements, recommendations, and comparison to previous inspection findings (Correct answer)

Correct answer: A written report with photographs, deficiency ratings, measurements, recommendations, and comparison to previous inspection findings

Comprehensive inspection documentation provides the record needed for engineering evaluation, maintenance planning, and regulatory compliance.

Question 11: During a tower inspection, what should be checked at the foundation level?

Just the tower identification plate
Concrete condition, exposed rebar, soil erosion, grout pad integrity, anchor bolt condition, and drainage (Correct answer)
Only the paint condition
Foundation inspection is only needed during construction

Correct answer: Concrete condition, exposed rebar, soil erosion, grout pad integrity, anchor bolt condition, and drainage

The foundation is what holds the tower up. Deterioration at the foundation affects the entire structure's stability.

Question 12: What determines the safe working load limit for a shackle used in tower rigging?

The foreman's estimate based on experience
The working load limit stamped on the shackle body by the manufacturer, which must never be exceeded (Correct answer)
Its physical size alone
Shackles have unlimited capacity

Correct answer: The working load limit stamped on the shackle body by the manufacturer, which must never be exceeded

Every rated shackle has a working load limit permanently marked on its body. Exceeding this limit risks catastrophic failure.

Question 13: A competent person inspects a full-body harness and discovers a frayed stitch on a load-bearing strap. What is the correct course of action?

Immediately remove the harness from service and destroy it to prevent reuse.
Note the fraying in the inspection log and allow continued use for one more week.
Apply duct tape over the frayed area to prevent further damage.
Use a lighter to carefully melt the frayed ends of the stitch. (Correct answer)

Correct answer: Use a lighter to carefully melt the frayed ends of the stitch.

According to ANSI Z359 standards and manufacturer requirements, any fall protection equipment that shows signs of wear, damage, or defects such as fraying, cuts, or chemical damage must be immediately removed from service. The harness should be tagged as unusable and preferably destroyed to ensure it cannot be accidentally used again.

Question 14: How should medications that cause drowsiness be handled for workers performing tower climbing?

Workers taking medications that impair alertness, balance, or coordination must not climb and should report medication use to their supervisor (Correct answer)
Only illegal drugs are a concern
Workers can take any prescribed medication
Medication use is a private matter that doesn't affect work

Correct answer: Workers taking medications that impair alertness, balance, or coordination must not climb and should report medication use to their supervisor

Medications causing drowsiness, dizziness, or impaired coordination create extreme fall risk when climbing.

Question 15: What is the difference between ionizing and non-ionizing radiation, and which type do tower antennas emit?

Tower antennas emit non-ionizing radiation, which causes tissue heating but does not have enough energy to break molecular bonds like ionizing radiation (Correct answer)
There is no difference between the two types
Tower antennas emit ionizing radiation
Both types are emitted equally by tower antennas

Correct answer: Tower antennas emit non-ionizing radiation, which causes tissue heating but does not have enough energy to break molecular bonds like ionizing radiation

RF energy from telecommunications antennas is non-ionizing — it can heat tissue but lacks the energy to damage DNA.

Question 16: What safety precaution must be taken when using a capstan hoist for tower work?

The operator must maintain proper wraps on the drum, never allow the rope to override, and keep hands clear of the pinch point (Correct answer)
Only wear sunglasses to prevent rope glare
Capstan hoists should never be used on towers
No precautions are needed — capstan hoists are self-regulating

Correct answer: The operator must maintain proper wraps on the drum, never allow the rope to override, and keep hands clear of the pinch point

Capstan hoists rely on friction between the rope and rotating drum. Improper wraps or contact with the pinch point can cause serious injuries.

Question 17: What is the primary purpose of a lift plan for tower hoisting operations?

To schedule material deliveries
To determine how many breaks workers get
To calculate labor costs
To document the load weight, rigging configuration, equipment ratings, and step-by-step procedure to ensure a safe lift (Correct answer)

Correct answer: To document the load weight, rigging configuration, equipment ratings, and step-by-step procedure to ensure a safe lift

A lift plan ensures all aspects of the hoisting operation have been thought through and equipment is properly rated.

Question 18: What is the difference between a bridle hitch and a basket hitch for sling use?

A bridle hitch uses two separate slings to support a load from above, while a basket hitch wraps a single sling under and around the load (Correct answer)
A bridle hitch is only for wire rope
A basket hitch is only for synthetic slings
They are the same thing

Correct answer: A bridle hitch uses two separate slings to support a load from above, while a basket hitch wraps a single sling under and around the load

Different hitch configurations provide different load control and capacity characteristics.

Question 19: Why is weld inspection important on welded tower structures and components?

Welds never fail once they are completed
Welds can develop cracks, porosity, and corrosion that reduce structural capacity, especially under cyclic wind loading (Correct answer)
Weld inspection is only needed for new construction
Only the tower manufacturer needs to inspect welds

Correct answer: Welds can develop cracks, porosity, and corrosion that reduce structural capacity, especially under cyclic wind loading

Welds are subject to fatigue cracking under cyclic loading from wind, thermal cycling, and vibration.

Question 20: What is a critical lift and what additional precautions does it require?

Any lift over 10 pounds is critical
Only lifts performed with a crane are critical
Critical lifts only occur during initial tower construction
A lift involving maximum equipment capacity, irreplaceable items, proximity to hazards, or unusual conditions requiring enhanced planning and supervision (Correct answer)

Correct answer: A lift involving maximum equipment capacity, irreplaceable items, proximity to hazards, or unusual conditions requiring enhanced planning and supervision

Critical lifts involve higher-than-normal risk factors that require additional planning and supervisory oversight.

Question 21: What RF safety signage is required at telecommunications tower sites?

Signs are required only for broadcast towers
Signs are only needed at the tower top
No signage is required
Warning signs must be posted at all access points to areas where RF levels may exceed general public exposure limits (Correct answer)

Correct answer: Warning signs must be posted at all access points to areas where RF levels may exceed general public exposure limits

FCC regulations require RF warning signs at boundaries where RF levels exceed uncontrolled/general public limits.

Question 22: What coordination is required with wireless carriers regarding RF safety before performing tower work?

Only the nearest carrier needs to be contacted
Coordination is only needed for new antenna installations
Workers must contact all carriers on the tower to request RF power reduction or shutdown for antennas in the work area, and verify confirmation before entering RF hazard zones (Correct answer)
No coordination is needed if you have an RF monitor

Correct answer: Workers must contact all carriers on the tower to request RF power reduction or shutdown for antennas in the work area, and verify confirmation before entering RF hazard zones

Modern towers may host equipment from multiple carriers. All carriers must be contacted because each contributes to the cumulative RF environment.

Question 23: A crew is preparing to work on a tower located near overhead power lines. Which of the following is the MOST critical initial safety precaution?

Determining the voltage of the power lines to establish the minimum approach distance (MAD). (Correct answer)
Verifying that the crane has a current annual inspection.
Checking the local weather forecast for the next 48 hours.
Ensuring all crew members are wearing high-visibility vests.

Correct answer: Determining the voltage of the power lines to establish the minimum approach distance (MAD).

When working near energized power lines, the most critical first step is to identify the line's voltage to determine the OSHA-mandated Minimum Approach Distance (MAD). All work, including the movement of personnel and equipment, must be planned to stay outside this distance to prevent electrocution.

Question 24: How should a hard hat suspension system be inspected for serviceability before each use?

Check only the outer shell for cracks and dents
Replace the suspension every 6 months regardless of condition
Inspect suspension bands for fraying, tears, loss of elasticity, and check that all attachment points are secure (Correct answer)
Clean the suspension with solvent to check for hidden cracks

Correct answer: Inspect suspension bands for fraying, tears, loss of elasticity, and check that all attachment points are secure

The suspension system absorbs impact energy; it must be checked for fraying, tears, loss of elasticity, and secure attachment to the shell before each use to ensure it will perform correctly in an impact.

Question 25: A gin pole is being used to lift a new tower section. Which component of the gin pole assembly is primarily responsible for attaching the entire apparatus to the existing tower structure?

The load block
The tag line
The rooster head
The clamp assembly (Correct answer)

Correct answer: The clamp assembly

A gin pole consists of three basic parts: a pole (mast), a pulley assembly (rooster head/load block), and the clamp assembly. The clamp assembly is what physically secures the gin pole to the leg or a structural member of the tower, providing the foundation for the lift.

Question 26: What is the maximum free-fall distance allowed by OSHA when using a personal fall arrest system?

10 feet
12 feet
6 feet (Correct answer)
4 feet

Correct answer: 6 feet

OSHA 1926.502(d)(16) limits free-fall distance to 6 feet when using a personal fall arrest system.

Question 27: Which of the following is a primary responsibility of the foreman during the daily Job Safety Analysis (JSA) or tailgate meeting?

To complete the JSA paperwork alone before the crew arrives to save time.
To have each crew member quickly sign the JSA form without discussion to get the day started.
To lead a discussion of the day's tasks, associated hazards, and mitigation plans, ensuring all crew members understand and provide input. (Correct answer)
To delegate the JSA meeting to the most senior technician on the crew.

Correct answer: To lead a discussion of the day's tasks, associated hazards, and mitigation plans, ensuring all crew members understand and provide input.

The JSA is an essential, interactive safety planning tool, not just a piece of paperwork. The foreman must lead the discussion, actively engaging the entire crew to identify hazards and agree on controls. This collaborative process ensures everyone on site is aware of the risks and the plan to work safely.

Question 28: A signal person is communicating with a crane operator to swing the boom to the left. What is the standard OSHA hand signal for this command?

Forearm vertical, index finger pointing up, making small circles.
Arm extended, thumb pointing down, flexing fingers in and out.
Both arms extended horizontally, swinging them back and forth.
Arm extended horizontally, with the index finger pointing in the direction of the swing. (Correct answer)

Correct answer: Arm extended horizontally, with the index finger pointing in the direction of the swing.

The standard OSHA and ASME hand signal for swinging a crane boom is to extend the arm horizontally with the index finger pointing in the intended direction of the boom's movement.

Question 29: How does a foreman ensure effective crew resource management during complex tower operations?

Distribute tasks based on individual competencies, maintain situational awareness, and encourage open communication among all crew members (Correct answer)
Focus only on the fastest workers
Assign the most experienced worker to do everything
Let crew members choose their own tasks

Correct answer: Distribute tasks based on individual competencies, maintain situational awareness, and encourage open communication among all crew members

Effective crew resource management matches workers to tasks based on their skills and creates an environment where anyone can raise safety concerns.

Question 30: What is the correct response when weather conditions deteriorate while workers are on a tower?

Continue working if the job is almost complete
Wait on the tower for the weather to pass
Workers must descend immediately when lightning, high winds, or severe weather threatens (Correct answer)
Only the foreman needs to descend

Correct answer: Workers must descend immediately when lightning, high winds, or severe weather threatens

Lightning and high winds pose immediate life-threatening risks to tower workers at elevated, exposed positions with metal structures.

Question 31: A technician is using a personal fall arrest system while working on a tower. What is the maximum allowable free-fall distance permitted by OSHA and ANSI standards?

2 feet
12 feet
6 feet (Correct answer)
4 feet

Correct answer: 6 feet

Both OSHA (e.g., 29 CFR 1926.502) and ANSI Z359 standards specify that a personal fall arrest system must be rigged such that an employee cannot free fall more than 6 feet. Positioning device systems are limited to a 2-foot free fall.

Question 32: Which glove material offers the best protection against cuts and abrasions while maintaining dexterity for tower climbing tasks?

Standard leather work gloves
Cut-resistant ANSI Level A4 gloves (Correct answer)
Latex gloves
Disposable nitrile gloves

Correct answer: Cut-resistant ANSI Level A4 gloves

ANSI Level A4 cut-resistant gloves provide high protection against lacerations from sharp metal edges and hardware while retaining sufficient dexterity for climbing and rigging tasks.

Question 33: A technician is installing antenna mounting hardware that specifies a torque value of 60 ft-lbs for the 5/8" bolts. The technician only has a torque wrench that measures in inch-pounds. What value should the technician set the wrench to?

660 in-lbs
600 in-lbs
720 in-lbs (Correct answer)
120 in-lbs

Correct answer: 720 in-lbs

To convert foot-pounds (ft-lbs) to inch-pounds (in-lbs), you multiply by 12, because there are 12 inches in a foot. Therefore, 60 ft-lbs multiplied by 12 equals 720 in-lbs.

Question 34: According to OSHA and ANSI Z359 standards, a personal fall arrest system (PFAS) anchorage point must be capable of supporting a minimum of how many pounds per attached worker?

5,000 lbs (Correct answer)
3,600 lbs
2,500 lbs
1,800 lbs

Correct answer: 5,000 lbs

OSHA 29 CFR 1910.268(g) and ANSI/ASSP Z359.1-2016 require that anchorages used for personal fall arrest systems must be capable of supporting at least 5,000 pounds (22.2 kN) per employee attached, or be designed, installed, and used as part of a complete personal fall arrest system which maintains a safety factor of at least two, under the supervision of a qualified person.

Question 35: Suspension trauma following a fall arrest event occurs because:

Blood pools in the legs while hanging motionless, restricting its return to the heart (Correct answer)
Harness straps overheat in direct sunlight and restrict breathing
Dehydration is accelerated when working at elevated heights
The impact forces during the fall cause internal bruising

Correct answer: Blood pools in the legs while hanging motionless, restricting its return to the heart

When a worker hangs motionless in a harness, the leg muscles stop pumping blood back to the heart, causing blood to pool and potentially leading to circulatory collapse.

Question 36: What should a foreman do if they determine a tower structure appears to be compromised or damaged?

Reinforce the damaged area with available materials
Stop all work, evacuate workers from the tower, secure the site, and report the condition to the tower owner and engineer (Correct answer)
Proceed with caution and climb slowly
Only report it after the current job is complete

Correct answer: Stop all work, evacuate workers from the tower, secure the site, and report the condition to the tower owner and engineer

A compromised tower could fail catastrophically. Work must stop immediately and structural assessment by a qualified engineer must be completed.

Question 37: What is the proper method for storing rigging equipment between uses?

Store clean, dry equipment in a protected location organized by type, with synthetic slings away from chemicals and UV light (Correct answer)
Store everything in one large container for convenience
Pile everything in the back of the truck
Storage doesn't matter as long as equipment is inspected before use

Correct answer: Store clean, dry equipment in a protected location organized by type, with synthetic slings away from chemicals and UV light

Proper storage prevents deterioration from moisture, UV exposure, chemical contact, and physical damage.

Question 38: What emergency equipment must be readily available at every tower work site?

First aid kit, rescue equipment, fire extinguisher, emergency communication devices, and eyewash if chemical hazards exist (Correct answer)
Only a cell phone
Emergency equipment is only required for large crews
A ladder is sufficient

Correct answer: First aid kit, rescue equipment, fire extinguisher, emergency communication devices, and eyewash if chemical hazards exist

Immediate access to emergency equipment can mean the difference between life and death on a tower site.

Question 39: A capstan hoist is being used to lift materials up a tower. What is a primary safety prohibition regarding the use of this type of hoist?

Running the engine for more than 30 minutes continuously
Operating it in wet weather conditions
Using it to lift loads heavier than 100 lbs
Using it for hoisting personnel (Correct answer)

Correct answer: Using it for hoisting personnel

OSHA regulations and industry standards, such as ANSI/ASSP A10.48, explicitly prohibit the use of capstan hoists for lifting personnel. These hoists are designed for materials only, and a base-mounted drum hoist is required for personnel lifts.

Question 40: According to FCC OET Bulletin 65, the human body most efficiently absorbs RF energy, and thus the Maximum Permissible Exposure (MPE) limits are most restrictive, within which frequency range?

3 kHz to 300 kHz
1 GHz to 10 GHz
30 GHz to 300 GHz
30 MHz to 300 MHz (Correct answer)

Correct answer: 30 MHz to 300 MHz

FCC OET Bulletin 65 specifies that whole-body absorption of RF energy by humans is most efficient in the 30-300 MHz frequency range. Because of this higher absorption rate, the MPE limits are at their most restrictive in this range to provide adequate protection.

Question 41: According to OSHA directives regarding hoisting personnel on communication towers, if a hoist has a maximum rated load capacity of 2,000 lbs for materials, what is its maximum load capacity when used for lifting personnel?

500 lbs
1,500 lbs
1,000 lbs (Correct answer)
2,000 lbs

Correct answer: 1,000 lbs

OSHA directive CPL 02-01-056 specifies that when hoisting personnel, the hoist's specified rated capacity must be de-rated by a factor of 2 (reduced by half). Therefore, a hoist rated for 2,000 lbs for materials would have a personnel load capacity of 1,000 lbs. This provides an increased safety factor for lifting people.

Question 42: Which of the following best describes a 'fall restraint' system?

A net system designed to catch a falling worker
A system that prevents a worker from reaching a fall hazard (Correct answer)
A system that arrests a worker's fall after it has begun
A system designed to lower a worker at a controlled speed

Correct answer: A system that prevents a worker from reaching a fall hazard

A fall restraint system is designed to prevent the worker from reaching an edge or other area where a fall could occur. It typically consists of a body harness, a lanyard of a specific length, and an anchorage, which physically prevents the worker from stepping off the edge. This is different from a fall arrest system, which stops a fall in progress.

Question 43: What does OSHA's General Duty Clause (Section 5(a)(1)) require of employers?

Employers must pay for all worker training
Employers must provide a workplace free from recognized hazards likely to cause death or serious harm (Correct answer)
Employers must provide health insurance
Employers must hire only certified workers

Correct answer: Employers must provide a workplace free from recognized hazards likely to cause death or serious harm

The General Duty Clause requires employers to furnish a place of employment free from recognized hazards causing or likely to cause death or serious physical harm.

Question 44: In the event of a chemical spill, what is the first action you should take?

Try to clean up the spill immediately
Cover the spill with absorbent material
Ignore it if it seems minor
Evacuate the area and notify the appropriate personnel (Correct answer)

Correct answer: Evacuate the area and notify the appropriate personnel

The first action should be to evacuate the area to ensure personal safety and then notify the appropriate personnel to handle the spill.

Question 45: Which of the following PPE is essential for protecting workers from falling objects?

Earplugs
Safety goggles
Hard hat (Correct answer)
Safety harness

Correct answer: Hard hat

A hard hat is essential PPE for protecting workers from head injuries caused by falling objects.

Question 46: What is the purpose of a structural analysis when adding new equipment to an existing tower?

To determine the best paint color for new equipment
Structural analysis is only needed for new tower construction
To verify the tower can safely support the additional weight and wind loading without exceeding structural capacity (Correct answer)
To calculate the cost of the installation

Correct answer: To verify the tower can safely support the additional weight and wind loading without exceeding structural capacity

Every piece of equipment added increases both gravity loading and wind loading. Without analysis, additions may overload the tower.

Question 47: What is the shelf life of most latex and rubber PPE components such as rubber insulating gloves when stored properly?

They have no shelf life; replace only on visible damage
Indefinite if stored in a cool, dark place
Determined by the manufacturer with periodic retesting required (Correct answer)
3 years from manufacture date

Correct answer: Determined by the manufacturer with periodic retesting required

Rubber and latex PPE components such as insulating gloves have manufacturer-specified shelf lives and must be periodically retested for continued electrical protection, regardless of appearance.

Question 48: When installing jumper cables between the main transmission line and antenna ports, what critical specification must be maintained?

Jumpers must be exactly 6 feet long
The jumper color must match the main cable
The jumper brand must match the antenna brand
The jumper impedance must match the system impedance, typically 50 ohms (Correct answer)

Correct answer: The jumper impedance must match the system impedance, typically 50 ohms

Impedance mismatches between jumpers and the system create signal reflections and power loss, degrading the antenna system's performance.

Question 49: Which NWSA guideline addresses the maximum weight limit that a full-body harness must be rated for, including tools and equipment?

310 lbs (141 kg) total, including worker, clothing, tools, and equipment (Correct answer)
500 lbs (227 kg) for heavy-duty harnesses
250 lbs (113 kg) body weight only
400 lbs (181 kg) combined weight

Correct answer: 310 lbs (141 kg) total, including worker, clothing, tools, and equipment

NWSA and ANSI Z359 standards require full-body harnesses used in tower work to be rated for a total system load of 310 lbs (141 kg), encompassing the worker, clothing, and all carried tools and equipment.

Question 50: Current American Heart Association (AHA) guidelines recommend a CPR chest compression rate of:

80 compressions per minute
150 compressions per minute
100–120 compressions per minute (Correct answer)
60 compressions per minute

Correct answer: 100–120 compressions per minute

The AHA recommends a compression rate of 100–120 per minute to generate adequate blood flow during cardiac arrest.

Question 51: What must be done before using a synthetic sling for hoisting on a tower?

Synthetic slings don't need inspection because they don't rust
Only check the color coding
Nothing — synthetic slings are always ready to use
Inspect for cuts, abrasion, UV degradation, knots, acid damage, and verify the sling is rated for the intended load (Correct answer)

Correct answer: Inspect for cuts, abrasion, UV degradation, knots, acid damage, and verify the sling is rated for the intended load

Synthetic slings degrade from UV exposure, chemicals, heat, and physical damage. Pre-use inspection prevents sling failure.

Question 52: How should bolt connections be evaluated during a tower inspection?

Only check bolts that appear loose
Bolt connections last forever and don't need inspection
Visual inspection from the ground is sufficient
Check for proper torque, corrosion, missing nuts or washers, thread engagement, and cracks around bolt holes (Correct answer)

Correct answer: Check for proper torque, corrosion, missing nuts or washers, thread engagement, and cracks around bolt holes

Bolted connections are the critical links. Failed connections can cause progressive collapse.

Question 53: After a fall arrest event, why must the harness and connecting devices be immediately removed from service?

They only need inspection, not removal
It is a superstition in the industry
They need to be cleaned before reuse
The shock-absorbing components may have deployed and structural integrity may be compromised (Correct answer)

Correct answer: The shock-absorbing components may have deployed and structural integrity may be compromised

Fall arrest subjects equipment to extreme forces that can cause invisible damage to webbing fibers, deform hardware, and deploy shock absorbers.

Question 54: On a lattice-type self-supporting tower, what is the primary function of the diagonal members that crisscross between the main tower legs?

To provide attachment points for antennas and transmission lines.
To serve as the primary climbing facility for technicians.
To act as the main vertical load-bearing components of the structure.
To resist shear forces from wind and transfer loads between horizontal members. (Correct answer)

Correct answer: To resist shear forces from wind and transfer loads between horizontal members.

In a truss structure like a lattice tower, the diagonal members are critical for providing rigidity and resisting shear (side-to-side) forces. They create triangular shapes, which are inherently stable, and transfer the wind and other lateral loads down the tower to the foundation.

Question 55: An AED (Automated External Defibrillator) is specifically designed to treat:

Ventricular fibrillation and pulseless ventricular tachycardia (Correct answer)
Anaphylactic shock reactions
Traumatic injuries causing blood loss
Respiratory arrest with absent pulse

Correct answer: Ventricular fibrillation and pulseless ventricular tachycardia

AEDs deliver a controlled electrical shock to reset shockable cardiac rhythms — specifically ventricular fibrillation and pulseless ventricular tachycardia.

Question 56: A Class E hard hat is rated to protect against electrical exposure up to what voltage?

30,000 volts (Correct answer)
20,000 volts
10,000 volts
5,000 volts

Correct answer: 30,000 volts

Class E (Electrical) hard hats are tested and rated to protect against electrical shock up to 20,000 volts phase-to-ground, with a 30,000-volt dielectric strength test.

Question 57: How does ice loading affect tower structural integrity?

Ice adds substantial weight to all structural members and equipment, increases wind loading due to larger cross-section, and can cause member failure (Correct answer)
Ice has no significant effect on towers
Ice damage only occurs in arctic regions
Ice only affects guy wires

Correct answer: Ice adds substantial weight to all structural members and equipment, increases wind loading due to larger cross-section, and can cause member failure

Ice accumulation dramatically increases both dead weight and wind load on towers.

Question 58: Which document should be consulted for information on handling hazardous materials?

Lockout/Tagout (LOTO) procedures
Safety Data Sheet (SDS) (Correct answer)
Job Safety Analysis (JSA)
Emergency Action Plan (EAP)

Correct answer: Safety Data Sheet (SDS)

An SDS provides detailed information about hazardous materials, including safe handling, storage, and emergency procedures.

Question 59: What is the primary purpose of a Job Safety Analysis (JSA)?

To evaluate job performance
To increase work speed
To identify and control hazards (Correct answer)
To schedule work shifts

Correct answer: To identify and control hazards

A Job Safety Analysis (JSA) is used to identify potential hazards associated with job tasks and to develop strategies to control or eliminate those hazards.

Question 60: During a rescue operation of a conscious suspended worker, what action can the worker take to help mitigate the effects of suspension trauma while awaiting rescue?

Remain as still as possible to conserve energy.
Tuck their chin to their chest to protect their airway.
Cross their arms tightly across their chest.
Push against a structure or use suspension trauma relief straps to create a foothold. (Correct answer)

Correct answer: Push against a structure or use suspension trauma relief straps to create a foothold.

Using leg muscles by pushing against a surface or using specially designed suspension trauma relief straps helps to pump blood back toward the heart. This muscular contraction counteracts the venous pooling in the legs that causes suspension trauma. Remaining still is the worst thing a suspended worker can do.
