When handling booms and rigging, which of the following practices is essential?

Ensuring all parts are supported before removing bolts or pins is crucial for safety when handling booms and rigging. This practice is essential because it prevents the uncontrolled movement of the load, which could lead to accidents or injuries. If components are not adequately supported and are suddenly released from their attachments, they may fall or shift unexpectedly, potentially causing harm to workers or damaging equipment. Securing the entire assembly before any disassembly is a fundamental safety measure in rigging operations.

In contrast, rushing to complete the job increases the risk of mistakes and accidents, as does removing pins without taking the necessary precautions or checks. Furthermore, standing under the boom does not enhance visibility and poses a considerable risk, as it places a person in the path of a potentially hazardous load. Thus, prioritizing support and safety measures is critical in ensuring safe hoisting operations.
