How should communications be established and maintained between the entry team and the RCS?

• A. Rely on visual hand signals only, with no radio use.
• B. Conduct a pre-entry brief, assign radio channels and call signs, maintain continuous monitoring, implement defined check-ins at intervals, and use hand signals if radios fail.
• C. Communications are not necessary once entry begins.
• D. Only the Facility Owner should communicate with the entry team.

Answer: (B)

Establishing and maintaining communications during entry hinges on a structured, redundant approach that keeps the entry team and the Re-Entry Control Supervisor (RCS) in lockstep. Start with a pre-entry briefing that clearly defines the mission, hazards, roles, and the communication plan so everyone knows how and when to communicate. Assign fixed radio channels and call signs to prevent message mix-ups, especially in environments with multiple teams or concurrent operations. Keep continuous monitoring by the RCS to have real-time awareness of the team’s status and changing conditions, and implement defined check-ins at regular intervals to verify safety and time management. Have hand signals ready as a backup for immediate, non-electronic communication if radios fail, and ensure all team members understand them before entry.

This combination creates a reliable, auditable flow of information that preserves situational awareness and provides redundancy. Relying only on hand signals can miss messages in limited visibility or noisy environments. Communications aren’t unnecessary once entry begins because conditions can change rapidly and require ongoing contact. Limiting communication to the Facility Owner excludes the RCS and entry team from critical updates and decision-making.
