In a radio blackout or power loss, safety hinges on built-in redundancy and multiple ways to stay in touch. The supervisor should immediately switch to backup channels, use predefined hand signals or other agreed signaling methods, and keep contact through any available means. This approach ensures direction and coordination aren’t lost when the primary system goes down, preserving situational awareness and enabling continued safe management of the re-entry operations. Preplanned hand signals and alternate signaling methods should be practiced so all team members recognize and respond quickly, and other methods of communication—such as visual signals, written notes, or auxiliary devices—should be leveraged as available to maintain continuous contact. Relying only on the primary channel risks losing coordination during the outage, stopping operations is unsafe, and ceasing signaling eliminates crucial information flow when it’s most needed.
