What should be the first step when a spill is identified during operations?

When a spill is identified during operations, the appropriate first step is to secure the affected area. Securing the area is crucial because it helps to prevent further exposure or contamination of individuals and protects the surrounding environment from potential hazards caused by the spill.

By securing the area, you effectively minimize the risk of others inadvertently walking into the contaminated zone, which could lead to increased exposure or complicate the cleanup efforts. Once the area is secured, the next logical steps would involve notifying a supervisor and assessing the situation for safe cleanup procedures, but the initial action should always prioritize safety by controlling access to the affected area.

It's essential to address spills in a systematic way to ensure the safety of all personnel and to handle radiological materials responsibly.
