What should be done if transmission is necessary for safety warnings?

When transmission is necessary for safety warnings, it is critical to transmit the emergency message regardless of any ongoing communications. This is because safety warnings are paramount and may involve urgent situations where lives could be at risk. The priority in these circumstances is to ensure that the warning reaches those who might be affected, as delays can exacerbate hazardous scenarios. The established protocols recognize that communication about imminent dangers takes precedence over routine transmissions.

In emergent situations, waiting for clearance or notifying all stations is impractical and could potentially lead to serious consequences if the information is time-sensitive. Holding the transmission until the channel is clear could also delay the delivery of crucial safety information. Therefore, the appropriate course of action is to prioritize safety warnings by transmitting them immediately.
