FIBER
OPTIC INSPECTION
FO All Twin-Path® slings have the Fiber Optic
inspection. The condition of the internal core
yarn can be inspected by checking the continuity
of the fiber optic cable. If heat, chemicals, crushing
or cutting has occurred then the damage to the
fiber optic cable will destroy its ability to transmit
light from one end to the other giving the inspector
a reason to remove the sling from service and send
it for repair evaluation. The fiber optic cable
will conduct light using natural, overhead or flashlight
sources.
