How must workers signal for assistance if necessary according to RWP?

Workers must signal for assistance using predetermined hand signals or communication devices as part of Roadway Worker Protection (RWP) protocols. This method ensures a standardized and clear form of communication that is recognized and understood by all workers and operators in the vicinity. By employing predetermined signals or devices, workers can effectively convey their need for assistance without causing confusion or misinterpretation, crucial for maintaining safety on the worksite, especially in noisy or chaotic environments. This approach minimizes risk and enhances coordination among crew members, facilitating swift and effective responses in emergency situations.

Verbal commands, while they can be effective in some contexts, may not be reliable in loud environments where clear communication is essential. Waving arms could lead to ambiguity in the intent of the signal. Utilizing flares, while potentially useful for increasing visibility, does not serve as a direct means of communicating an immediate need for assistance. Thus, the most effective and safe signaling method within the RWP framework is through established hand signals or communication devices.
