Which group is responsible for handling external requests for plant information during an emergency?

The spokesperson is specifically designated to manage communication with external parties, especially during emergencies. Their primary role is to ensure that accurate information is disseminated to the media, public, and regulatory agencies, while protecting the integrity and security of the facility's operations. Having a single point of contact helps prevent misinformation and confusion that can arise from multiple individuals providing differing accounts or data.

In emergency situations, it is crucial that consistent and accurate messaging is conveyed, and the spokesperson is trained to handle these situations effectively. This includes being knowledgeable about the facility's protocols and the current status of any incidents. By letting one individual manage external communications, the organization can maintain clarity and control over the narrative surrounding the emergency.

Others in the facility, such as the facility manager, would have a different set of responsibilities focused on operational response, while quality control personnel are concerned with maintaining standards and processes rather than external communications. The option of having all available staff handle communication would likely lead to confusion and a lack of cohesive messaging, which is why it is not the correct answer.
