What are the three classifications of loads?

• A. Standard, Heavy, Light
• B. Primary, Secondary, Tertiary
• C. Certified, Suitable, Unique
• D. Open, Closed, Restricted

Answer: (C)

Loads are categorized to determine how much planning, inspection, and supervision a lift requires. The three classifications—certified, suitable, and unique—define that level of control. Certified loads have documented validation of weight, center of gravity, dimensions, and rigging compatibility, with official data or certification backing the lift plan. Suitable loads don’t have formal certification but are within the rigging system’s limits and can be handled using standard procedures and verified data, under appropriate oversight. Unique loads are irregular or nonstandard and require a tailored rigging plan, possible custom hardware, and additional risk assessment and approval due to unusual balance or shape. The other groupings don’t reflect how loads are formally categorized for planning and safety in sling load operations.
