• B. One arm raised horizontally with palm facing the operator
• C. Both arms crossing in front of the body

Answer: (B)

The "stop" signal is crucial for maintaining safety on construction sites, and it is characterized by one arm raised horizontally with the palm facing the operator. This specific gesture is universally recognized by signal persons and operators as an immediate indication to halt all operations. The horizontal arm position and the open palm serve as clear visual communication, effectively conveying the message that the equipment should stop moving. This signal is designed to be easily distinguishable from other signals, ensuring that it captures the operator's attention quickly in various working conditions. Proper training emphasizes the importance of using the correct hand signals, as miscommunication could lead to accidents or mishaps on site.
