Q

What is an SRL and what does it do?

A

Self Retracting Lifeline
or “self-retracting lanyard”

Meet OSHA requirements to stop a fall in progress.
Per OSHA it is “a deceleration device which contains a drum wound line which may be slowly extracted from, or retracted onto, the drum under slight tension during normal employee movement, and which, after onset of a fall, automatically locks the drum and arrests the fall.”
Source: OSHA 1910.66 Appendix C

Q

What is a traveler device and how is it used?

A

Travelers or a “rope grab”
Example: Lad-Saf™ flexible cable system
OSHA says it is “a deceleration device which travels on a lifeline and automatically frictionally engages the lifeline and locks so as to arrest the fall of an employee. A rope grab usually employs the principle of inertial locking, cam/lever locking, or both.”

Q

What is a position system and how is it used?

A

Positioning system (work-positioning system) means a system of equipment and connectors that, when used with a body harness or body belt, allows an employee to be supported on an elevated vertical surface, such as a wall or window sill, and work with both hands free. Positioning systems also are called “positioning system devices” and “work-positioning equipment.”

Q

How ofter should roped access safety gear be inspected?

A

Every 8 hour shift by individual using it
and
More often than yearly by “competent rescuer”

According to ANSI/ASSE Z359.2-2007 American National Standards Section 5.5.2 Fall protection equipment shall be inspected by the authorized person at least once at the beginning of each eight hour shift in which it is used to verify that it has not sustained any wear or damage that would require its removal from service. Fall protection and fall rescue equipment shall be inspected on a regular basis not to exceed one year (or more frequently if required by the manufacturer’s instructions) by a competent person or a competent rescuer, as appropriate, to verify that the equipment is safe for use. The inspection shall be documented

Q

Describe the difference between dynamic and static ropes.

A

Dynamic:
- Sport climbing rope
- Has stretch to absorb energy of fall
- Has elongation > 10%
- Not good for lifting gear, rappelling, or ascending

Static Rope:
- Working or Professional rope
- Little stretch
- Has elongation < 10%
- Good for hauling, lifting gear, rappelling, or ascending
