Access must be controlled through _____ and ____ points to allow for personnel accountability and control.

• A. Front door and back door
• B. entry and exit
• C. Controller and release
• D. Primary and secondary

Answer: (B)

Access control relies on directing personnel through clearly defined entry and exit points to track who is inside a hazardous area at any given time. Having designated points for movement creates choke points where sign-in/sign-out can be recorded, times checked, and PPE and condition verified, so the incident command can maintain accurate personnel accountability and know where everyone is. This approach also supports orderly flow and ensures there’s a clear method to account for all equipment and personnel as people come and go.

The other options are less fitting because they describe specific doors or abstract concepts rather than the mechanism used to manage access and accountability in a collapse environment.
