• Inspection: visual inspection of the condition of the sling to identify any obvious damage or wear which could adversely affect its operating capabilities.

• Thorough examination: a visual examination performed by a skilled person who, if necessary, uses other means such as non destructive tests, in order to identify any damage or wear which could adversely affect the operating capabilities of the sling.
