Core Concepts and Principles Flashcards

What is the minimum experience typically required before a SPRAT Level I can test for Level II?

Answer: 500 hours and 6 months

SPRAT requires 500 logged rope access hours and 6 months at the previous level to advance.

How often must SPRAT certification be renewed?

Answer: Every 3 years

SPRAT certifications are valid for three years and require recertification.

Under OSHA 29 CFR 1910.27 for rope descent systems, what minimum strength must each anchorage support per worker?

Answer: 5,000 pounds

OSHA requires rope descent anchorages capable of supporting at least 5,000 lbs per attached worker.

Which statement correctly describes chemical vulnerability of rope fibers?

Answer: Nylon is more vulnerable to acids, while polyester is more vulnerable to strong alkalis

Nylon degrades in acids and polyester degrades in strong alkalis, so chemical exposure must be assessed.

Why is a pre-use buddy check performed before going on rope?

Answer: A second technician verifies harness, connectors, devices, and rigging to catch errors

Peer checks catch rigging and equipment errors before the technician is committed to the ropes.

What is the main hazard of hot work, such as welding, near nylon or polyester ropes?

Answer: Heat and sparks can melt or weaken synthetic fibers

Synthetic rope fibers melt at relatively low temperatures, so ropes must be protected from heat and sparks.

What is the minimum rope access team size under SPRAT safe practices?

Answer: Two technicians, so one can perform rescue

Rope access work requires at least two technicians so rescue is always possible.
