What is a Safety transmission?

A Safety transmission is defined as a communication that indicates a station is preparing to transmit an important navigation or weather warning. This type of transmission is critical in maritime and aviation contexts, where timely and accurate information is essential for the safety and well-being of individuals and operations.

When a station announces a Safety transmission, it is often alerting other users in the vicinity that vital safety information is about to be communicated, thus helping them to prepare for the information they will receive. Typically, this is associated with broadcasts regarding navigational hazards or urgent weather changes that might affect operations.

This understanding is particularly important for operators who need to recognize the seriousness of the situation being addressed, thus ensuring that they give proper attention to the information being conveyed.
