What must be ensured regarding the signal before moving equipment?

Before moving equipment, it is essential to ensure that the signal is unmistakably clear. This clarity is vital for safety and effective communication on a worksite. A clear signal helps prevent accidents and misunderstandings among workers, particularly in environments where loud machinery and multiple activities are occurring simultaneously.

An unmistakably clear signal means that all personnel involved understand the intention behind the signal and can respond appropriately without ambiguity. It serves as a critical safety protocol to ensure that everyone is aware that movement is about to occur, thereby reducing the risk of collisions or injuries.

While some might argue for other aspects such as the signal being given by an authority figure, or that it can be optional, these concepts do not address the fundamental need for clarity in communication to maintain a safe working environment. Ignoring the signal based on assumed knowledge of conditions further increases the likelihood of dangerous situations. The necessity for clarity emphasizes the priority of safety in operational procedures.
