Which option is not a sling load classification?

• A. Certified
• B. Unique
• C. Prohibited
• D. Invalid

Answer: (D)

Sling load classifications tell you whether a load is eligible for sling loading and what handling it requires. The official categories are Certified, Prohibited, and Unique. Certified means the load has been evaluated and approved for sling loading under the standard rigging and procedures. Prohibited means the item must not be sling loaded due to safety or compatibility concerns. Unique covers items that don’t fit the standard categories and require special handling or approvals. Invalid, however, isn’t a sling load classification; it signals an input or status issue rather than a way to categorize the load.
