livslängd på sele

[Mezzner]

Du hade ju en ganska heltäckande disclaimer .

Sen är det väl så att det är rätt subjektivt och kan finnas viss variation mellan tillverkarna också.
Jag har t o m för mig att jag har WC-hardware där max livslängd varit angiven, medan man svarade lite annorlunda på en direkt fråga.

Man ska väl trots allt se till att man alltid har osäkerhetsintervallen på rätt sida i sin bedömning, inte minst eftersom man i praktiken ofta nyttjar utrustningen gemensamt i ett replag och då bör man ju kanske se till att man kan stå för sina bedömningar.

Personligen kommer jag nog knappast att kassera nån karbin som är väl bibehållen, men äldre än en viss ålder bara för att jag med nån karbin fått en varudeklaration där det hävdats att så ska göras. Självklart är dock detta ingen rekommendation åt andra som jag tar ansvar för...

"When working in a vertical environment, it’s important to
know that your harness is in the best shape possible. To ensure
this, a harness must be cared for and inspected regularly. While
each harness is built differently, the following is a series of
general recommendations on how to inspect your harness
1. Under ideal storage conditions, the shelf life of an
unused harness is between 4-7 years. After being
used, most harness manufacturers recommend a 2-3
year maximum service life.
2. Harnesses should be inspected before each use, as
well as undergoing a regular maintenance check by a
qualified person. Equipment found to be damaged in
any way should be taken out of service immediately.
3. Visual indications of damage to webbing and rope include:
a. Shriveled brownish appearance. When exposed to excessive heat, fibers shrink and turn
brownish in color. Fibers may break when flexed. Harnesses should not be stored in
environments exceeding 180°F.
b. Unusual smears or smudges. Chemical damage can appear as discolored patches on the
harness, usually turning brown in color.
c. Cracks in the harness.
d. Loss of elasticity in the webbing.
e. Hard shiny spots or brittle feel. This can be the result of direct exposure to flame, which
causes the webbing to fuse together.
f. Discoloration, including paint spots. When paint penetrates and dries, it restricts movement
of fibers. Drying agents and solvents in some paints may also cause chemical damage.
g. Pulled/Loose threads
h. Any other unusual/obvious signs of damage
4. During the regular maintenance check, a qualified person should check the following (depending
on your harness, some may not apply):
a. Webbing. Grasp the webbing with your hands 6 to 8 inches apart. Bend the webbing in an
inverted “U”. Inspect the full length of both sides of each strap, looking specifically for
frayed edges, broken fibers, pulled stitches, cuts, burns and chemical damage.
b. D-Rings. D-Rings should be inspected for distortions, cracks, breaks, and rough or sharp
edges. D-rings should move freely. The attachment points should be free from unusual
wear and frayed or cut fibers.
c. Buckles. Like D-Rings, buckles should be
free of distortions, cracks, breaks, and rough
or sharp edges. All bars should be straight,
and the center bar should overlap with the
outer frame of the buckle. All moving
parts should also be free to move properly.
Attachment points should be free from
unusual wear and frayed or cut fibers.
d. Tongue. The part of the harness that passes
through a buckle (known as the tongue)
receives a lot of wear from repeated
buckling and unbuckling. It should be
inspected for loose, distorted or broken
grommets, as well as for additional holes
punched through the webbing.
e. Back pads. Back pads should be inspected
for any signs of obvious wear or damage.
As always, it is ultimately up to you to judge
whether or not your equipment is safe to use.
While harnesses are expensive items, it is better to
err on the side of caution and replace it rather than
running the risk of a potential accident."
