What must be avoided during periods of emergency communication?

During periods of emergency communication, it is essential to avoid interference from non-emergency messages because such interference can create confusion and potentially prevent critical information from getting through. Emergency communications are time-sensitive and require clear and immediate transmission of distress signals or important safety information. When non-emergency messages are transmitted simultaneously, they can obstruct the frequency or channel being used by those in distress, leading to a delay in response from rescue services or other vessels. This principle is critical in ensuring that the communication channel remains clear for urgent matters, differentiating between life-threatening situations and routine exchanges.

In contrast, changes in communication protocols may delay the response but could also enhance overall communication effectiveness if properly executed. Excessive radio checks could contribute to congestion but are usually considered a lesser issue than outright interference. Over-reliance on visual signals might be discussed regarding redundancy, as it is important not to depend solely on one form of communication in emergencies. However, the primary focus remains on ensuring that communication channels are free from any non-emergency traffic that could hinder timely and effective emergency responses.
