c. Periodic Inspection – This inspection shall be conducted by a designated person.Frequency of inspection should be based on:

1. Frequency of use
2. Severity of service conditions
3. Experience gained on the service life of polyester round slings used in similar applications
4. Periodic inspections should be conducted at least monthly


TEMPERATURE: Manufactured from polyester, round slings are seriously graded at temperatures above 200 degrees.
IMPROPER LOADING: Shock loading, unbalanced loading, overloading and inadequate consideration for the effect angle factors can adversely effect strength.
CUTS, PUNCTURES, ABRASIONS: When sleeve on a round sling has been damaged so that the inner load bearing yarns can be exposed, the sling MUST be removed from service.
