What is the proper position of the arms when using the emergency hand stop signal?

The proper position of the arms when using the emergency hand stop signal is arms extended horizontally with palms down. This hand signal is universally recognized in various industries, particularly in construction and rigging, as a clear and immediate way to communicate the necessity to halt operations. By extending the arms horizontally and facing the palms down, it creates a visual cue that is easily noticeable and conveys urgency.

Using this specific position ensures that all personnel on site, whether they are familiar with each other or not, can quickly recognize the signal and respond appropriately. It is designed to minimize confusion and enhance safety in situations where immediate action is required to prevent accidents or injuries. Proper training in these signals is essential for maintaining a safe working environment, highlighting the importance of clear communication among team members.
