What does the term "out of service" mean concerning rigging equipment?

The term "out of service" in the context of rigging equipment refers specifically to equipment that is no longer safe for use, often due to visible damage or a decrease in performance. This condition necessitates that the equipment is tagged to indicate that it should not be used until it has been properly inspected, repaired, or deemed safe for operation again.

Safety is paramount in rigging operations, and identifying equipment that is out of service ensures that hazards are minimized and that personnel are protected from potential accidents. If an item shows signs of wear, damage, or has been compromised in any way, its operational capacity is questioned, and its use is prohibited until it meets safety standards again.

In contrast, the other choices describe conditions or states of equipment that do not align with the notion of being "out of service." For instance, being in excellent condition or maintained regularly implies a functional state, while upgrades suggest enhancements rather than deficiencies.
