Question: According to CSA Z150, when is it permissible to temporarily 'field repair' a damaged wire rope sling and return it to service?
Answer options:
- When minor broken wires are noted but the core is intact.
- When the sling has been load tested after the repair.
- Only when authorized by a qualified person and documented. ✅ Never; damaged wire rope slings must always be removed from service.
Correct answer: Never; damaged wire rope slings must always be removed from service.
Explanation: CSA Z150, and generally all safety standards, strictly prohibit field repairs of damaged wire rope slings. Once a wire rope sling exhibits damage criteria for removal, it must be removed from service and either discarded or sent to a qualified professional for full recertification if possible (which is rare for a sling).
