What action should assist staff refrain from unless absolutely necessary?

The correct answer highlights the importance of structured communication within a team in safety-critical situations. Talking without direction from the leader can lead to confusion, mixed messages, and potentially exacerbate an already tense situation. It's crucial for staff to understand that any communication should be coordinated and purposeful, as this helps maintain clarity and ensures that everyone is aligned with the established response plan.

Clear communication is essential in safety protocols to avoid misunderstandings that might compromise safety or escalate an incident. Team members need to focus on a unified approach directed by leadership to facilitate effective responses. Uncoordinated or unsolicited communication may disrupt this process and hinder safety efforts.

In contrast, the other actions listed—intervening if necessary, following the leader's instructions, and monitoring the situation—are generally encouraged as they contribute to maintaining safety and managing incidents effectively when executed under proper guidance.
