Which administration control can be implemented to work in both directions, whereby emitter controllers or operators and maintenance personnel are both made aware of each other's actions before proceeding into the hazardous area?

• A. Flashing Lights/Audible Signals
• B. Prior Coordination
• C. Electric Shock or Burn Safety Equipment
• D. Laser Radiation

Answer: (B)

Prior coordination is an administrative control that ensures both emitter controllers or operators and maintenance personnel communicate and confirm each other’s actions before anyone enters a hazardous area. By requiring mutual notification, confirmation of shutdowns or energy isolation, and agreement on the sequence of tasks, both sides stay informed and avoid unexpected energy release or equipment start-up. This bidirectional awareness is what makes it effective for coordinating work across teams. Warning signals like flashing lights or audible alarms can alert people but don’t guarantee that both parties are aligned on what’s happening; safety equipment protects individuals but doesn’t establish communication or sequencing; and laser radiation is a hazard itself, not a coordinating control.
