Fading of webbing color.
Nylon and polyester web slings possess a limited useful
service life due to the degradation caused by exposure
to sunlight or other measurable sources of UV radiation.
Lift-All web slings that are regularly exposed to UV
radiation should be identi昀椀ed with the date they are
placed into service and should be proof-tested to twice
their rated capacity every six months.
Visible indication of such environmental
deterioration can include the following:
•
•
Sunlight / UV Exposure Service Life
Web
Slings
Exposure to sunlight and other environmental
factors can result in accelerated deterioration of
web slings. The rate of this deterioration varies
with the level of exposure and with the thickness of
the sling material.
