A manufacturer's certificate of proof test may satisfy the initial test requirements for rigging equipment.

• A. True
• B. False
• C. Not sure
• D. Only certain equipment

Answer: (B)

Initial testing of rigging equipment is about verifying that the item is safe and suitable for your specific use, in your actual setup and conditions. A manufacturer’s certificate of proof test shows that the item withstood a prescribed load during manufacturing, but it doesn’t address how the equipment will perform in your particular use, with your attachments, handlers, and environment. It also doesn’t replace the field checks, inspections, and any additional proof testing required by the standards you’re following. Because of that, you can’t rely solely on the factory proof-test certificate to satisfy the initial test requirements. You need the appropriate field or independent verification as specified by the applicable rigging standards.
