What is the call for a SAFETY signal used for?

The call for a SAFETY signal is specifically used for transmitting essential information regarding navigational hazards or meteorological updates that could affect the safety of navigation. This signal is important for ensuring that mariners are informed about potential dangers that may not be immediately apparent, such as changes in weather conditions or obstacles in the water.

The SAFETY signal serves a critical purpose in maritime communication, allowing vessels to relay important information in a way that helps others avoid accidents and make informed decisions while navigating. This distinguishes the SAFETY signal from distress signals which indicate emergencies requiring immediate assistance, or general announcements, which do not pertain specifically to safety concerns.
