When using chains for securing a load, which guideline is correct?

• A. Chains are for lighter loads and smooth surfaces; verify incorrect guidelines.
• B. Chains are for heavier loads and rough surfaces; verify correct working load limit, avoid twists, and secure with appropriate tension.
• C. Straps are for heavy loads on rough surfaces; ensure correct WLL.
• D. Only use chains with no regard to weight.

Answer: (B)

When securing with chains, the idea is that they are used for heavier loads and rough surfaces where high strength is needed. The best guideline is to verify the chain’s working load limit for the specific setup, avoid twists in the chain, and secure it with the right tension. The working load limit ensures the chain can safely handle the load and any forces encountered during transit. Twists create stress concentrations and can weaken the chain, reducing its effectiveness and increasing the risk of failure. Applying proper tension keeps the load from shifting, which is crucial on rough surfaces where movement is more likely. In contrast, straps are typically used for lighter loads and smoother surfaces, and using chains without regard to weight or WLL is unsafe.
