addition, a verification inspection
should be carried out, by a
competent person every year that a
unit remains in service. A written
record of such inspection should be
retained on file.
4.3 OSHA defines a competent person
as one who is capable of identifying
hazardous or dangerous conditions
in the personal fall arrest system or
any component thereof, as well as
in their application and use with
related equipment.
4.4 WHAT TO LOOK FOR WHEN
CHECKING OVER YOUR
EQUIPMENT:
Webbing:

sides and from end to end. Flex the
webbing over your fingers, bending it to

webbing, straps, and reinforcing points
carefully for wear and tear from fastening
and unfastening buckles, and attaching
snap hooks.
Look for cut, pulled or broken stitches,
or frayed or damaged strands in the
woven web. Discolored, fused, brittle or
melted fibers may signs of chemical,
paint, solvent, burning or heat damage
(figure 2).
Hardware:
Inspect all buckles, D-rings
and other metal components for cracks
that may signal the beginning of metal
fatigue. Also check for sharp or rough
edges that could cut webbing, rust or
other corrosion, distortion, or other signs
of wear. Check the metal wear pad at the
base of D-rings and make sure the
D-ring pivots freely. Tongue buckles
should have rollers that turn freely;
tongues should not be bent out of
shape, should move freely back and
