What compatibility considerations must be checked when using different types of rigging gear together?

• A. Ensure compatible WLL ratings, chemical compatibility, temperature limitations, and proper spread of load across different gear types; avoid mismatched assemblies.
• B. Mixing gear is acceptable if loads are small.
• C. Cross-compatibility is irrelevant as long as load is small.
• D. Use only the same manufacturer, ignoring other properties.

Answer: (A)

When you mix different rigging gear, you have to check how they work together in four areas: the ratings, how each material reacts to chemicals, the temperatures it can withstand, and how the load is shared across the different pieces. The strongest reason this option is best is that the overall safety of the lift depends on making sure every component can handle its part of the load; if one piece has a lower working load limit, or if a material is damaged by a chemical or heat, the whole assembly can fail even if the others seem fine. So you verify that the working load limits are compatible so the weakest link governs the capacity, confirm chemical compatibility so solvents or cleaners don’t weaken fibers or coatings, check temperature limits because heat can degrade some gear, and ensure the load is spread properly across the gear types to avoid overloading any single piece. This approach prevents dangerous mismatches and hidden overloading. Mixing gear simply because the loads are small or using gear from the same manufacturer does not guarantee safety if these compatibility factors aren’t addressed.
