3. Certification and Marking Make sure that the relevant Certificate has been obtained before taking the rope into use for a lifting operation. Check to verify that the marking on the rope or its package matches the relevant Certificate. Note: The rating of a component part of a machine or lifting accessory is the responsibility of the designer of the machine or accessory. Any re-rating of a lifting accessory must be approved by a competent person. Retain the Certificate in a safe place for identification of the rope when carrying out subsequent periodic statutory examinations in service.
