What is the difference between Arrived at Scene (10-23) and Assignment Completed (10-24)?

• A. 10-23 means task finished; 10-24 arrival
• B. 10-23 indicates you have reached the scene; 10-24 indicates the task is finished.
• C. 10-23 is for backup; 10-24 is for status update
• D. 10-23 means equipment check; 10-24 means incident closed

Answer: (B)

These codes distinguish being on scene from finishing a task. Arrived at Scene signals you have reached the location of the incident and are on-scene, ready to participate in the response. Assignment Completed indicates that the task you were assigned is finished, and you’re no longer actively working on that assignment. So the difference is arrival versus completion: 10-23 marks your physical presence at the scene, while 10-24 marks the finish of the assigned duty. The other options mix up these meanings (e.g., arrival vs. completion or unrelated duties), which doesn’t fit how these codes are used in practice.
