On which VHF channel should safety information be provided after an initial call?

Safety information after an initial call is typically provided on Channel 06, which is designated for intership safety communications and is commonly used for relaying safety information among vessels in proximity. This channel allows for efficient communication of urgent safety details without congesting the more widely monitored emergency channel, which is Channel 16.

Channel 16 is the internationally recognized distress, urgency, and safety calling channel, primarily used to initiate calls and signal emergencies. After establishing communication, the transition to Channel 06 for specific safety messages helps to maintain the clarity and accessibility of emergency broadcasts.

Channel 12 and Channel 22 are not generally utilized for disseminating safety information in the same manner as Channel 06. Channel 12 is often used for port operations, while Channel 22 may be allocated for specific regional communications, which do not specifically cater to safety information post-initial call.

Thus, using Channel 06 for safety communications is based on efficient maritime communication protocols, ensuring that critical information is shared effectively without interfering with emergency services.
