What are standards used to make decisions on whether to remove an object from service called?

The correct answer is "rejection criteria." This term refers to the specific standards and guidelines that determine whether an object, such as lifting equipment or rigging gear, should be removed from service due to safety concerns or potential failure. Rejection criteria are essential in ensuring that equipment remains safe to use, helping to identify when it has reached a point of deterioration or damage that could lead to accidents or injury during operations.

Rejection criteria typically include parameters such as wear and tear, deformation, corrosion, or any other condition that compromises the integrity of the equipment. By adhering to these criteria, personnel can make informed decisions about the usability of equipment, thus maintaining safety standards in the workplace.

Other options may refer to various concepts in safety or operational processes, but they do not specifically address the metrics or standards set for determining the unsuitability of an object for continued use.
