Question 1Maritime Craft Fundamentals and Safety

Before entering a confined space aboard a vessel, what must be verified first?

  1. The space lighting is connected to shore power
  2. The ventilation fan has been running for one hour
  3. The space has been tested for oxygen and hazardous gases Correct answer.
  4. The crew has finished loading cargo

Explanation

Confined space entry requires atmospheric testing for oxygen content and toxic or flammable gases before anyone enters, and testing must continue while the space is occupied. Ventilation and lighting are supporting controls, but they do not replace verified test results.

Question 2Maritime Craft Fundamentals and Safety

A worker on a vessel's deck must wear a personal flotation device whenever the worker is:

  1. Working over or near the water Correct answer.
  2. Inside the engine room
  3. Eating lunch in the mess hall
  4. Handling mooring lines on the pier

Explanation

Fall-overboard risk drives the requirement: a PFD is worn when work is performed over or adjacent to water, and often when working on open decks. The other listed locations or tasks do not present the same immediate immersion hazard.

Question 3Maritime Craft Fundamentals and Safety

Which signal should a rigger give the crane operator when the load must be stopped immediately, regardless of any prior command?

  1. A thumbs-up gesture
  2. A circular motion of the arm
  3. A raised clenched fist Correct answer.
  4. A hand waved side to side

Explanation

The emergency stop signal is a raised clenched fist, and it overrides any other signal being given. Standard hand signals must be agreed on before the lift so the operator reacts instantly.

Question 4Maritime Craft Fundamentals and Safety

What is the primary purpose of a vessel's muster list?

  1. To list the vessel's cargo stowage plan
  2. To assign each crew member a specific emergency duty and station Correct answer.
  3. To track the fuel consumption of the main engine
  4. To record the crew's daily work hours

Explanation

The muster list assigns every person aboard a station and duty for emergencies such as fire or abandon ship. It is posted so crew can learn their roles before an emergency occurs.

Question 5Maritime Craft Fundamentals and Safety

When lifting a load with a chain hoist, the load should be raised:

  1. Rapidly to reduce the time under load
  2. Just enough to clear the deck before checking the rigging Correct answer.
  3. While a crew member steadies it by hand underneath
  4. With the chain at an angle to the vertical

Explanation

A trial lift of a few inches lets the rigger confirm balance, sling seating, and brake function before the load is committed to full height. Rapid lifts and angled pulls increase shock loading and loss of control.

Question 6Maritime Craft Fundamentals and Safety

A fire on a vessel involving cooking oil in a galley deep fryer is best classified as which class of fire?

  1. Class D
  2. Class C
  3. Class A
  4. Class K Correct answer.

Explanation

Class K fires involve combustible cooking media such as vegetable oils and animal fats, and they require a wet chemical extinguishing agent. Water or standard dry chemical can cause the burning oil to splash and spread.

Question 7Maritime Craft Fundamentals and Safety

Before a wire rope sling is used for a lift, the rigger should reject it if it shows:

  1. A tag showing a capacity greater than the load
  2. Broken wires, kinks, or crushed sections Correct answer.
  3. A slightly oily coating from storage
  4. Light surface rust that wipes off

Explanation

Broken wires, kinks, birdcaging, and crushed or heat-damaged sections reduce sling strength and are grounds for removal from service. Surface conditions that do not affect strength are not automatic rejection criteria.

Question 8Maritime Craft Fundamentals and Safety

What does the term 'dead ship' mean in the context of vessel operations?

  1. The vessel is moored with no crew aboard
  2. The vessel is carrying a deceased crew member
  3. The vessel has lost all power and cannot operate its propulsion or steering Correct answer.
  4. The vessel has completed its final voyage before scrapping

Explanation

A dead ship condition means the main and auxiliary power sources have failed, so propulsion, steering, and essential systems are unavailable. This is a serious emergency because the vessel may drift and lose control.

Question 9Maritime Craft Fundamentals and Safety

A worker must cross a gangway between ship and shore. Which practice is correct?

  1. Use the gangway only when the safety net and handrails are in place Correct answer.
  2. Carry a heavy load on the shoulder while crossing
  3. Run across quickly to reduce the time on the gangway
  4. Cross when the tide is changing without checking the gangway angle

Explanation

A gangway must have handrails and a safety net, and it must be properly secured and at a safe angle before use. Running, carrying awkward loads, or crossing during tide changes increases the risk of a fall into the water.

Question 10Maritime Craft Fundamentals and Safety

When a vessel is taking on water in a compartment, the first response should be to:

  1. Open the compartment to equalize pressure
  2. Pump the water overboard without locating the leak
  3. Wait for the next scheduled watch change
  4. Sound the alarm, notify the bridge, and locate the source Correct answer.

Explanation

Flooding requires immediate alarm and notification so the crew can respond as a team, followed by locating and controlling the source. Delaying notification or acting alone allows the flooding to spread.

Question 11Maritime Craft Fundamentals and Safety

Which item is part of a mariner's personal protective equipment for hot work on deck?

  1. Steel-toe boots only
  2. Leather gloves and a face shield Correct answer.
  3. Safety glasses only
  4. A hard hat only

Explanation

Hot work such as welding and cutting requires protection against sparks, heat, and ultraviolet light, so leather gloves and a face shield are standard. Single items like a hard hat or glasses leave other exposure uncovered.

Question 12Maritime Craft Fundamentals and Safety

What is the main purpose of a vessel's fire control plan?

  1. To document the results of the last safety drill
  2. To list the vessel's fuel and lube oil inventory
  3. To show the location of fire boundaries, extinguishing systems, and escape routes Correct answer.
  4. To record the names of crew assigned to cargo watch

Explanation

The fire control plan is a posted drawing showing fire zones, extinguishing equipment, and escape routes so responders can act quickly. It is a reference for emergency response, not an administrative log.

Question 13Maritime Craft Fundamentals and Safety

A mooring line is being led to a bollard. Which practice protects the crew?

  1. Place a foot on the line to control it
  2. Stand clear of the line's snap-back zone Correct answer.
  3. Stand between the line and the bitt
  4. Hold the line with bare hands to feel tension

Explanation

A parting or surging mooring line can snap back with lethal force, so crew must stay outside the snap-back zone. Hands and feet must never be placed on or under a loaded line.

Question 14Maritime Craft Fundamentals and Safety

Which condition indicates that a portable fire extinguisher must be removed from service?

  1. The extinguisher has a current inspection tag
  2. The extinguisher is mounted in a bracket
  3. The pressure gauge needle is in the recharge range Correct answer.
  4. The extinguisher has been shaken during inspection

Explanation

A gauge reading in the recharge or low-pressure range means the extinguisher may not discharge properly and must be recharged or replaced. A current tag and proper mounting are signs of a serviceable unit.

Question 15Maritime Craft Fundamentals and Safety

What is the correct action when a crew member discovers a small fire that can be safely extinguished?

  1. Raise the alarm, then attack the fire with the correct extinguisher Correct answer.
  2. Extinguish it quietly and report it at the end of the shift
  3. Spray water on any fire to cool it quickly
  4. Open nearby doors to ventilate the smoke

Explanation

The alarm must be raised first so the crew and bridge are aware, then a trained person may attack a small fire with the correct agent while keeping an escape route. Failing to alarm or ventilating the space can let the fire spread.

Question 16Maritime Craft Fundamentals and Safety

In a permit-to-work system aboard a vessel, the permit primarily serves to:

  1. Replace the need for a supervisor during the task
  2. Document that specified hazards were assessed and controls put in place before work starts Correct answer.
  3. Authorize overtime pay for the crew
  4. Record the vessel's position at the start of the job

Explanation

A permit-to-work formalizes the hazard assessment, isolations, and controls for high-risk tasks such as hot work or confined space entry. It supplements supervision rather than replacing it.

Question 17Maritime Craft Fundamentals and Safety

Which factor most increases the risk of a fall when working aloft on a mast?

  1. Working in daylight with a spotter below
  2. Using a safety harness without a proper anchorage point Correct answer.
  3. Inspecting the harness before climbing
  4. Wearing a hard hat with a chin strap

Explanation

A harness only protects the worker if it is attached to a suitable anchorage that can arrest a fall. Unanchored or improvised attachment defeats the purpose of the fall protection system.

Question 18Maritime Craft Fundamentals and Safety

What does the term 'man overboard' require the crew to do first?

  1. Reduce speed only after the person is recovered
  2. Sound the alarm, notify the bridge, and keep the person in sight Correct answer.
  3. Continue the current task until the watch changes
  4. Launch the rescue boat before alerting the bridge

Explanation

Immediate alarm and bridge notification allow the vessel to maneuver for recovery, while keeping visual contact guides the rescue. Launching a boat or slowing without coordination delays the response.

Question 19Maritime Craft Fundamentals and Safety

A hydraulic line on deck has burst and fluid is spraying near a hot exhaust. What is the priority action?

  1. Increase engine speed to clear the line
  2. Wipe the fluid with rags while the system runs
  3. Stop the equipment, isolate the pressure, and remove ignition sources Correct answer.
  4. Continue working until the shift ends

Explanation

Pressurized hydraulic fluid is a fire and injection hazard, so the system must be shut down and depressurized and ignition sources controlled. Cleaning while the system runs or continuing work leaves the hazard active.

Question 20Maritime Craft Fundamentals and Safety

When using a lifebuoy with a light and smoke signal, the purpose of the smoke is to:

  1. Mark the position for recovery in daylight and low visibility Correct answer.
  2. Provide warmth to a person in the water
  3. Signal the vessel to increase speed
  4. Indicate the wind direction to the bridge

Explanation

The smoke and light on a lifebuoy mark the location so the vessel can maneuver back to the person. They are position markers, not heating or signaling devices for speed changes.

Question 21Maritime Craft Fundamentals and Safety

Which statement about a vessel's stability is correct when a heavy weight is lifted by the ship's crane?

  1. The center of gravity falls and stability always improves
  2. The metacenter moves below the keel
  3. The vessel's draft decreases in all cases
  4. The center of gravity rises and the vessel's stability may decrease Correct answer.

Explanation

Lifting a weight with the ship's own crane raises the combined center of gravity, which can reduce metacentric height and increase the risk of a dangerous list. Stability must be checked before heavy lifts.

Question 22Maritime Craft Fundamentals and Safety

What is the function of a vessel's inert gas system on a tanker?

  1. To cool the cargo tanks during loading
  2. To provide breathing air for the crew
  3. To pressurize tanks for faster discharge
  4. To keep tank atmospheres below the flammable range by reducing oxygen Correct answer.

Explanation

Inert gas systems fill cargo tanks with oxygen-depleted gas so the atmosphere stays too lean to support combustion. They are a fire and explosion prevention measure, not a cooling or breathing-air supply.

Question 23Maritime Craft Fundamentals and Safety

A crew member is directed to work on a suspended stage over the side. Which control is essential?

  1. A life jacket worn under the harness
  2. A spotter on the bridge wing
  3. A radio kept in the tool bag
  4. A fall arrest system with an independent lifeline and a standby person Correct answer.

Explanation

Over-the-side work on a stage requires fall arrest with an independent lifeline and a standby person to monitor and assist. A life jacket under a harness can interfere with the harness, and a radio in a bag is not immediately accessible.

Question 24Maritime Craft Fundamentals and Safety

Which action best reduces the risk of a dropped object injuring crew on the deck below?

  1. Passing tools by hand between levels
  2. Tethering tools and barricading the area beneath the work Correct answer.
  3. Working faster to shorten the exposure time
  4. Relying on hard hats to stop falling tools

Explanation

Dropped object prevention relies on tool tethering and excluding people from the area below the work. Hard hats offer limited protection against heavy falling objects, and speed or hand-passing increases risk.

Question 25Maritime Craft Fundamentals and Safety

What is the correct way to store a charged CO2 extinguisher aboard a vessel?

  1. Kept in a locked cabinet with no access during emergencies
  2. Stored in the engine room next to the exhaust manifold
  3. Secured upright in its designated bracket, clear of heat sources Correct answer.
  4. Laid horizontally in a storage locker

Explanation

Extinguishers must be secured upright in their designated locations so they are accessible and ready for use. Storage near heat or in locked, inaccessible places defeats their purpose and can damage the unit.

Question 26Maritime Craft Fundamentals and Safety

Under the maritime safety color code, what does a red marking on a piece of deck equipment typically indicate?

  1. Electrical hazard requiring lockout
  2. Fire protection equipment or its controls Correct answer.
  3. Potable water supply line
  4. Safe walking route during emergencies

Explanation

In the standard maritime color-coding scheme, red identifies fire protection appliances and their operating controls, such as hydrant valves and extinguisher stations. Crew members learn this code so they can locate firefighting gear quickly under smoke or low light.

Question 27Maritime Craft Fundamentals and Safety

A seafarer is assigned to chip and paint steel on the foredeck. Which personal protective item is specifically required to protect the eyes from flying scale?

  1. Tinted sunglasses
  2. A cloth dust mask
  3. Safety goggles or a face shield Correct answer.
  4. A welding helmet with a dark lens

Explanation

Chipping hammers and needle guns throw sharp scale and metal fragments at high speed, so impact-rated eye protection such as goggles or a full face shield is required. Tinted or dark lenses do not provide impact resistance.

Question 28Maritime Craft Fundamentals and Safety

Which statement correctly describes the purpose of a vessel's muster list?

  1. It lists the cargo stowage plan for each hold
  2. It records the watch schedule for deck officers
  3. It tracks the maintenance history of lifesaving appliances
  4. It assigns each crew member a specific station and duty during an emergency Correct answer.

Explanation

The muster list, required under SOLAS, tells every person aboard where to go and what to do when an emergency alarm sounds. It covers duties such as firefighting teams, lifeboat preparation, and manning of emergency equipment.

Question 29Maritime Craft Fundamentals and Safety

During a lifeboat drill, a crew member must don an immersion suit. Which check confirms the suit is properly fitted before entering the water?

  1. The face seal allows only a small trickle of water
  2. The suit is stored in its original packaging
  3. The wearer can don it within two minutes and it covers the whole body except the face Correct answer.
  4. The wearer can climb a ladder unaided within the suit

Explanation

An immersion suit must be donned quickly, usually within two minutes, and must enclose the entire body except the face so that trapped air provides insulation. A properly sized suit still allows the wearer to climb a ladder and perform essential tasks.

Question 30Maritime Craft Fundamentals and Safety

Which knot is best suited for temporarily securing a line to a bollard or post so it can be released quickly under load?

  1. Bowline
  2. Figure-eight knot
  3. Sheet bend
  4. Clove hitch Correct answer.

Explanation

The clove hitch is a quick, adjustable hitch used to secure a line to a post, rail, or bollard, and it can be cast off rapidly. Other knots serve different purposes, such as forming a fixed loop or joining two ropes.

Question 31Maritime Craft Fundamentals and Safety

What is the primary reason a vessel maintains a watertight integrity log and keeps weathertight closures secured at sea?

  1. To preserve the vessel's reserve buoyancy and prevent progressive flooding Correct answer.
  2. To comply with cargo ventilation requirements
  3. To reduce wind resistance on deck
  4. To keep deck machinery free of salt spray

Explanation

Closing watertight doors, hatches, and vents preserves the subdivision and reserve buoyancy designed into the hull. If a compartment floods, properly secured closures limit the water to that space and keep the vessel afloat.

Question 32Maritime Craft Fundamentals and Safety

A crew member is handling a mooring wire on a winch drum. Which hazard is the most serious and requires keeping hands and feet clear?

  1. Wire rope snap-back and crushing at the drum nip Correct answer.
  2. Vibration transmitted through the deck
  3. Sunburn from prolonged exposure
  4. Noise from the winch motor

Explanation

Mooring wires store enormous energy, and a parted wire can snap back across the deck, while the drum nip can crush hands or feet. Crew must stand clear of the bight and the drum during tensioning.

Question 33Maritime Craft Fundamentals and Safety

Which of the following best describes the role of a vessel's safety committee?

  1. It investigates and reports on accidents and recommends corrective measures Correct answer.
  2. It certifies the seaworthiness of the hull
  3. It approves the vessel's cargo manifest
  4. It negotiates crew wages with the shipping company

Explanation

A shipboard safety committee brings together crew and management to review hazards, investigate incidents, and recommend improvements to working practices. It does not handle commercial or classification matters.

Question 34Maritime Craft Fundamentals and Safety

A tanker crew is preparing to enter an empty cargo tank for inspection. Which condition must be confirmed before entry is authorized?

  1. The adjacent tanks are loaded to full capacity
  2. The tank has been filled with seawater to displace residue
  3. The tank hatch has been left open for at least one hour
  4. The tank has been ventilated and tested to show acceptable oxygen and hydrocarbon levels Correct answer.

Explanation

Enclosed-space entry requires atmospheric testing for oxygen content, flammable gas, and toxic gas, plus continuous ventilation, before a permit is issued. An open hatch alone does not guarantee a safe atmosphere.

Question 35Maritime Craft Fundamentals and Safety

A vessel's fixed CO2 firefighting system is about to be discharged into the engine room. What must be confirmed first?

  1. That the watertight door to the space is propped open
  2. That the engine room ventilation fans are running at full speed
  3. That the fuel oil transfer pump is still operating
  4. That all personnel have evacuated the space and the space is sealed Correct answer.

Explanation

CO2 displaces oxygen and is lethal to anyone inside the protected space, so the space must be evacuated, accounted for, and sealed before release. Ventilation and openings must be shut so the gas is not swept away.

Question 36Maritime Craft Fundamentals and Safety

A bosun must choose a lifting sling for an abrasive steel load with sharp edges. Which sling type is most appropriate?

  1. Chain sling with worn links
  2. Natural fiber rope sling
  3. Wire rope sling without protection
  4. Synthetic webbing sling with edge protectors or a wire rope sling with softeners Correct answer.

Explanation

Sharp edges cut synthetic webbing and damage wire rope, so edge protection such as softeners or corner saddles is essential whatever sling is chosen. Worn chain links or unprotected slings risk sudden failure under load.

Question 37Maritime Craft Fundamentals and Safety

A crew member notices that a portable fire extinguisher's pressure gauge needle rests in the red zone. What does this indicate?

  1. The gauge is only a decorative label
  2. The extinguisher lacks sufficient pressure and must be recharged or replaced Correct answer.
  3. The extinguisher is overcharged and safe to use
  4. The extinguisher is fully charged and ready

Explanation

The gauge shows the internal pressure of the extinguisher; a needle in the red zone means the pressure is too low for reliable discharge. The unit must be removed from service and recharged or replaced.

Question 38Maritime Craft Fundamentals and Safety

During a man-overboard recovery, what is the purpose of the Williamson turn?

  1. It stops the vessel immediately in its track
  2. It increases speed to outrun the casualty
  3. It brings the vessel back along its original track to the casualty's position Correct answer.
  4. It turns the vessel broadside to the wind for shelter

Explanation

The Williamson turn is a maneuver that reverses the vessel's course and returns it along the reciprocal of the original track, which helps bring the ship back to where the person entered the water. It is especially useful at night or in reduced visibility.

Question 39Maritime Craft Fundamentals and Safety

Why must a vessel's lifeboat be lowered to the embarkation deck and checked before it is used in a drill?

  1. To warm the engine by running it at full throttle
  2. To test the lifeboat's radio at maximum range
  3. To confirm the release gear, falls, and brake function operate correctly under controlled conditions Correct answer.
  4. To empty the fuel tank before launching

Explanation

Lowering to the embarkation deck lets the crew verify that the davit brake, falls, and on-load release gear function properly without launching the boat. This controlled check reduces the risk of failure during a real abandonment.

Question 40Maritime Craft Fundamentals and Safety

A crew member is exposed to continuous noise from a deck winch measured at 95 dB(A). What is the correct response under a hearing conservation program?

  1. Use cotton wool as ear protection
  2. Increase the winch speed to shorten the exposure time
  3. No action is required because the exposure is below 100 dB(A)
  4. Wear hearing protection and limit the duration of exposure Correct answer.

Explanation

Sustained exposure at 95 dB(A) exceeds the typical 85 dB(A) action level, so hearing protection and exposure-time limits are required. Cotton wool does not provide adequate attenuation.

Question 41Maritime Craft Fundamentals and Safety

Which practice best prevents the buildup of static electricity when transferring flammable liquid between containers?

  1. Transferring at the highest possible flow rate
  2. Using plastic funnels and hoses throughout
  3. Bonding the containers together and grounding them to the vessel structure Correct answer.
  4. Wiping the containers with a dry cloth before transfer

Explanation

Bonding equalizes potential between containers and grounding drains the charge to the vessel's structure, preventing a spark that could ignite vapor. High flow rates and non-conductive equipment increase static generation.

Question 42Maritime Craft Fundamentals and Safety

A vessel's lifting appliance has a safe working load of 5 tonnes. What does this value represent?

  1. The weight of the appliance itself
  2. The maximum load the appliance may lift under the stated conditions Correct answer.
  3. The load at which the appliance begins to deform permanently
  4. The breaking strength of the wire rope divided by two

Explanation

The safe working load is the maximum load that may be lifted, derived from the breaking strength divided by a factor of safety and valid only for the specified configuration. Exceeding it removes the margin of safety.

Question 43Maritime Craft Fundamentals and Safety

A worker must descend into a cargo hold using a portable ladder. Which practice is correct?

  1. Carry tools in both hands for balance
  2. Slide down the side rails for speed
  3. Face the ladder and maintain three points of contact while descending Correct answer.
  4. Descend facing away from the ladder

Explanation

Maintaining three points of contact and facing the ladder keeps the body centered and reduces the chance of a slip. Tools should be hoisted or carried in a bag so both hands remain free.

Question 44Maritime Craft Fundamentals and Safety

A hydraulic crane on deck is being operated near the vessel's rail. Which factor most affects the crane's stability during the lift?

  1. The color of the crane's paint
  2. The temperature of the hydraulic oil reservoir
  3. The age of the crane operator's gloves
  4. The combined effect of the load moment and the vessel's list Correct answer.

Explanation

A crane's stability depends on the load moment relative to its rated capacity curve, and a vessel's list or trim shifts the effective load and can cause the crane to exceed its limits. Operators must account for list when slewing the load outboard.

Question 45Maritime Craft Fundamentals and Safety

A vessel is preparing for heavy weather. Which measure best protects the crew and cargo?

  1. Securing loose gear, checking lashings, and closing watertight openings Correct answer.
  2. Opening hatches to equalize pressure
  3. Leaving deck cargo unlashed so it can shift freely
  4. Increasing speed to reach port before the storm

Explanation

Heavy-weather preparation focuses on securing movable items, verifying lashings, and closing watertight and weathertight openings to preserve stability and prevent flooding. These actions reduce the risk of shifting cargo and water ingress.

Question 46Maritime Craft Fundamentals and Safety

A deckhand is asked to enter a pump room where the atmosphere has just been tested as safe. Which additional control is still required?

  1. A standby person at the entrance and a means of communication Correct answer.
  2. Locking the door from the outside
  3. Closing the ventilation to keep the air still
  4. Removing all lighting from the space

Explanation

Even after testing, enclosed-space entry requires a standby person at the entrance and a reliable means of communication so the entrant can be rescued if conditions change. Ventilation must continue and lighting must be provided.

Question 47Maritime Craft Fundamentals and Safety

A vessel's emergency generator fails to start during a blackout test. Which consequence most directly threatens the vessel's safety?

  1. Increased fuel consumption at the main engine
  2. Reduced speed of the main propulsion engine
  3. Loss of steering, emergency lighting, and fire pump power Correct answer.
  4. Loss of the galley refrigeration only

Explanation

The emergency generator supplies steering gear, emergency lighting, navigation lights, and the emergency fire pump, so its failure removes critical systems during a blackout. This is why it is tested regularly under load.

Question 48Maritime Craft Fundamentals and Safety

During a stability assessment, a vessel's metacentric height is found to be very small but positive. What is the primary concern?

  1. The vessel will have no reserve buoyancy
  2. The vessel will be excessively stiff and snap-roll
  3. The vessel will be unable to make headway
  4. The vessel will have a long, sluggish roll and may be tender in a seaway Correct answer.

Explanation

A small positive metacentric height means weak righting moments, producing a long roll period and a tender vessel that may heel excessively. Too large a value causes stiffness and violent rolling, so the value must be balanced.

Question 49Maritime Craft Fundamentals and Safety

A permit-to-work is issued for hot work on a tank that previously carried flammable cargo. Which condition makes the permit invalid?

  1. The atmosphere is re-tested and found to contain flammable vapor above the safe limit Correct answer.
  2. The fire watch is posted at the worksite
  3. Firefighting equipment is staged nearby
  4. The tank has been gas-freed and certified

Explanation

A hot-work permit depends on a continuously safe atmosphere, so any reading above the permitted flammable-vapor limit voids the permit and work must stop. The permit is only valid while all its stated conditions remain satisfied.

Question 50Maritime Craft Fundamentals and Safety

A vessel's mooring arrangement uses a mixed set of lines with different elastic properties. Which practice best reduces the risk of line failure?

  1. Leaving all lines slack so none carries load
  2. Leading lines so they share the load evenly and have similar elastic behavior Correct answer.
  3. Tightening one line to carry the entire load
  4. Using the shortest line for the heaviest load

Explanation

Lines with different elasticity share load unevenly, and the stiffer line may take most of the strain and part. Matching lines and adjusting them so they share load evenly is the recommended practice.
