NLC Rigging Practice Exam 2025 – 400 Free Practice Questions to Pass the Exam

Synthetic slings are primarily designed to address non-conductivity, which is a crucial safety feature in rigging applications. Non-conductive materials in slings are essential for preventing electrical hazards, particularly in environments where there is a risk of exposure to live electrical wires. This characteristic helps ensure that workers are protected from electrical shocks while using the slings for lifting and securing loads.

While the other options touch on important aspects of sling performance, they do not represent the primary safety focus of synthetic slings. Fire resistance, for instance, is beneficial but not as critical as the need to mitigate electrical hazards in many settings. Similarly, while temperature tolerance and weight-bearing capacity are significant factors, they do not specifically address the safety concern of electrical conductivity, making non-conductivity the primary area of safety addressed by synthetic slings.
