A 19 mm 6x19 IWRC wire rope sling is being inspected. In a single lay length, you observe three wires broken at the termination point of the eye splice and one wire broken in the running section. Additionally, the outer wires show 1/3 loss of their original diameter due to abrasion. Based on CSA Z150, which defect alone necessitates immediate removal from service?

Question: A 19 mm 6x19 IWRC wire rope sling is being inspected. In a single lay length, you observe three wires broken at the termination point of the eye splice and one wire broken in the running section. Additionally, the outer wires show 1/3 loss of their original diameter due to abrasion. Based on CSA Z150, which defect alone necessitates immediate removal from service?

Answer options:

• The combination of three broken wires at the termination point and one in the running section.
• The single broken wire in the running section.
• The 1/3 loss of outer wire diameter due to abrasion. ✅ All defects listed are individually grounds for removal.

Correct answer: All defects listed are individually grounds for removal.

Explanation: According to CSA Z150, three broken wires in a single strand in one lay (or six random broken wires in one lay) AND critical abrasion (typically 1/3 reduction in outer wire diameter) are individual grounds for immediate removal. The question presents both scenarios. Termination point breaks are especially critical. Therefore, all listed defects individually warrant removal.
