Which signal can be given by any worker during crane operations?

The emergency stop signal during crane operations is critical because it can be called by any worker present on the site. This is vital for ensuring safety, as it allows anyone who notices a dangerous situation or potential hazard to intervene immediately, regardless of their role.

The ability for any worker to give an emergency stop signal is a fundamental safety protocol in the operation of cranes. It ensures that all individuals involved in or around the lifting operation can take proactive measures to prevent accidents, injuries, or damage. This emphasizes the importance of communication and authority in regard to safety, as conditions at a worksite can change rapidly and unexpectedly.

In contrast, signals like the load up, boom down, or load down signals are typically designated to specific personnel, such as the crane operator or the designated signal person. This structured signaling system helps ensure that the lifting operations are conducted safely and efficiently, as only trained individuals are directing these more routine movements based on the established procedures.
