When choosing between chains and strap-type tie-downs, what guidelines govern their use?

• A. Chains are for heavier loads and rough surfaces; straps are easier on cargo; ensure correct working load limit, avoid twists, and secure with appropriate tension.
• B. Chains are preferred for all loads; straps are never allowed.
• C. Straps are for heavy loads on rough surfaces; chains for light loads; no tension required.
• D. There are no guidelines; either can be used interchangeably without tension.

Answer: (A)

Choosing between chains and strap-type tie-downs centers on matching the hardware to the load and the surface, while following safe securement practices. Chains are suited for heavier loads and rough or uneven surfaces because of their greater strength and resistance to movement under harsh conditions. Straps, on the other hand, are easier on cargo and work well for lighter loads or smoother surfaces where less aggressive restraint is sufficient. Regardless of which you use, you must select gear with an appropriate working load limit for the payload, inspect for wear or damage, avoid twists or knots that can reduce effectiveness, and apply the proper tension so the load doesn’t shift. When there are sharp edges, edge protection helps prevent strap fraying or chain damage, and proper attachment and tensioning ensure the restraint remains secure during transit.
