Roof Sailing Rigging and Line Systems 3

Question 1

Which factor most directly determines the 'total fall distance' a worker could travel before stopping in a fall arrest system?

Accepted Answer

Free-fall distance plus lanyard deployment plus worker height above lower level

Answer

The rated breaking strength of the anchor

Answer

The pitch of the roof surface

Answer

The diameter of the rope used in the lifeline

Question 2

When rigging a horizontal lifeline across a roof span, the anchor points must be positioned to minimize which hazard?

Accepted Answer

The swing-fall (pendulum) effect

Answer

Rope UV degradation

Answer

Harness fit changes

Answer

Tool drop distance

Question 3

What is the purpose of inspecting the rope's 'eye splice' before using it as a rigging attachment?

Accepted Answer

To verify the splice has the correct number of tucks and shows no pulled or broken strands

Answer

To check the rope's color coding is still visible

Answer

To confirm the rope is the correct color for the job

Answer

To measure the total length of the rope

Question 4

Which ANSI standard governs the design, performance, and testing of self-retracting lifelines (SRLs) used in roof rigging?

Accepted Answer

ANSI/ASSE Z359.14

Answer

ANSI A10.32

Answer

ANSI Z87.1

Answer

ANSI A14.3

Question 5

A worker notices the sheath of their kernmantle rope has a shiny, glazed appearance in one section. This most likely indicates:

Accepted Answer

Heat or friction damage that has weakened the fibers

Answer

Normal wear that does not affect safety

Answer

Exposure to moisture that has tightened the weave

Answer

Manufacturer's quality marking applied during production

Question 6

When using a descending device (rappel device) during roof access, the safety backup for the descender should be:

Accepted Answer

A friction hitch (prusik or klemheist) on a separate strand below the device

Answer

A second anchor tied off to the same point

Answer

A spotter holding the rope at the base

Answer

A locking carabiner clipped to the harness only

Question 7

What is the correct procedure when a rope used in a fall arrest system has actually arrested a fall?

Accepted Answer

Remove it from service immediately and label it for inspection or destruction

Answer

Inspect it visually and return it to service if no damage is visible

Answer

Dry it out and re-coil it for the next job

Answer

Have a coworker inspect it and decide on reuse
