Knots/Caring for cordage

Cordage is often expensive, and may be difficult to replace. For all cordage, there are some things you can do to maximize its lifespan:
 * Protect cordage from rough treatment
 * Do not stand on cordage, especially synthetics
 * Keep cordage away from chemicals, oil, grease dirt and grit
 * Avoid extremes of cold or heat
 * Limit exposure to sunlight, even for UV-stable cordage
 * Thoroughly wash and rinse your cordage regularly
 * Keep natural fibre ropes dry
 * Only short lengths of non-production rope should be folded; everything else should be coiled.
 * Load-bearing cordage must be inspected regularly
 * Look for cut or frayed fibres, wrinkled or ruptured sheath, glazing/fusing from thermal friction
 * Even though the sheath is flawless, it may mask internal damage
 * Keep a log for load-bearing cordage
 * Cordage with a history of hard work, or severe shock-loading should be retired or downgraded
 * Base your cordage life cycle on the specifications and the specific applications. Ask your vendor for assistance, if necessary, or get training.
