Rigging Week 1

What is the primary objective of a personal fall arrest system in the power delivery industry?

• To allow workers to climb without any restrictions

• To reduce the amount of arresting force on the employee during a fall

• To ensure workers can work with both hands free

• To provide comfort during long working hours

Answer explanation

section 1.2

Why is it important to limit the free fall distance to 6 feet or less in a fall arrest system?

• To ensure the employee can reach the ground safely

• To prevent the employee from swinging into structures

• To minimize the risk of suspension trauma

• To prevent the employee from contacting any lower level

Answer explanation

How does a shock absorbing lanyard reduce the arresting force on an employee during a fall?

• By increasing the free fall distance

• By absorbing the energy of the fall

• By shortening the lanyard length

• By providing additional support to the harness

Answer explanation

section 1.2.2

What is the role of a rope grab in a vertical lifeline system?

• To allow multiple employees to use the same lifeline

• To provide a connection point for the lanyard and lock during a fall

• To increase the length of the lifeline

• To act as a backup in case the lifeline fails

Why is it critical to ensure the D-ring on a body harness is positioned at the center of the employee’s back?

• To enhance the comfort of the harness

• To ensure the harness meets ANSI standards

• To distribute arresting forces evenly during a fall

• To allow for easy attachment of the lanyard

What is the significance of the ANSI Z359.1 standard in the context of body harnesses?

• It specifies the materials used in harness construction

• It ensures the harness can withstand a tensile load of 3,000 pounds

• It guarantees the harness meets OSHA’s maximum arresting force requirement

• It defines the proper sizing of body belts

How do self-retracting lifelines function similarly to a car seatbelt?

• They allow for unlimited free fall distance

• They lock up almost instantaneously during a fall

• They provide continuous support without locking

• They require manual adjustment to lock

What is the primary reason for using positioning device systems in the power delivery industry?

• To allow workers to climb without any fall protection

• To support workers on vertical surfaces with both hands free

• To provide a backup in case the fall arrest system fails

• To ensure compliance with OSHA regulations

Why is it important to keep the anchor point as high as practical while maintaining the ability to perform work?

• To reduce the risk of suspension trauma

• To minimize the swing fall distance

• To ensure the lifeline is always taut

• To allow for easier attachment of the lanyard

What is the potential consequence of suspension trauma if not addressed promptly?

• Increased comfort for the employee

• Enhanced mobility while suspended

• Loss of consciousness and risk of death

• Improved circulation to the legs
