The ________ is responsible for all responders moving between control lines.

The ________ is responsible for all responders moving between control lines.

• A. Incident Commander
• B. Site access control leader
• C. Safety Officer
• D. Public Information Officer

Answer: (B)

Controlling who moves across the different incident zones is the job of the Site Access Control Leader. This role sits at the access points and is responsible for authorizing entry and movement between control lines, ensuring that only trained and properly equipped responders cross into a new zone. They verify credentials, monitor decontamination status, and coordinate with the decontamination and operations teams so that crossing zones does not spread contamination or expose personnel. In short, this position keeps the flow of responders orderly and safe, maintains accountability, and prevents uncontrolled crossings. The Incident Commander provides overall incident command and decision-making; the Safety Officer focuses on hazard controls and worker protection but does not manage the day-to-day movement between zones; the Public Information Officer handles communications with external audiences.
