Question: An HEO inspects a chain sling and finds that a link has a 12% elongation. According to CSA B335, what action should be taken?

Answer options:

• The sling can be used but with a reduced Working Load Limit.
• The elongated link can be replaced on-site by the HEO. ✅ The sling must be immediately removed from service.
• The sling should be marked for annual inspection.

Correct answer: The sling must be immediately removed from service.

Explanation: CSA B335 specifies that if a chain link has permanent elongation exceeding 5% of its original dimension, the chain sling must be immediately removed from service because its structural integrity has been compromised and it poses a significant failure risk.
