PSD Interagency Coordination and Mutual Aid 3 — Questions and Answers
Question 1: When two agencies operate under Unified Command, how are tactical operations typically directed?
- Each agency independently directs its own personnel
- Through a single Operations Section Chief acting under the unified commanders (Correct answer)
- By rotating command authority hourly between agencies
- Through a joint dispatch center that issues all orders
Correct answer: Through a single Operations Section Chief acting under the unified commanders
Under Unified Command, a single Operations Section Chief is typically designated to direct tactical operations, even though strategic decisions are made jointly.
Question 2: A dispatcher is tracking mutual aid units from three different counties. Which ICS tool is BEST suited for maintaining real-time status of these resources?
- The Incident Action Plan
- The Resource Status Unit (T-CARD) system (Correct answer)
- The Common Operating Picture display
- The Communications Plan (ICS 205)
Correct answer: The Resource Status Unit (T-CARD) system
The Resource Status Unit uses T-CARDs or equivalent tools to track real-time status (available, assigned, out-of-service) of all resources including mutual aid units.
Question 3: In the context of public safety dispatching, 'interoperability' most accurately refers to:
- Sharing personnel between agencies during emergencies
- The ability of agencies to communicate seamlessly across different systems (Correct answer)
- Joint training exercises conducted between departments
- Common database access for records management
Correct answer: The ability of agencies to communicate seamlessly across different systems
Interoperability is the ability of public safety agencies to communicate with one another across different radio systems, frequencies, or technologies during an incident.
Question 4: During a declared disaster, a dispatcher coordinates with a National Guard liaison. Which principle ensures the Guard operates under appropriate civilian authority?
- Posse Comitatus Act
- Civil Support authority under Title 32 (Correct answer)
- EMAC interstate compact provisions
- Stafford Act disaster declaration requirements
Correct answer: Civil Support authority under Title 32
National Guard forces operating under Title 32 (state active duty or federally funded state service) remain under the governor's authority, ensuring civilian control during disasters.
Question 5: A dispatcher's agency is the 'host' in a mutual aid event. What is the host agency's primary responsibility regarding incoming mutual aid resources?
- Providing fuel and maintenance for all incoming vehicles
- Briefing, assigning, and tracking incoming resources effectively (Correct answer)
- Reimbursing all mutual aid costs within 30 days
- Allowing incoming resources to self-dispatch to incidents
Correct answer: Briefing, assigning, and tracking incoming resources effectively
The host agency is responsible for effectively briefing, assigning work, and tracking all incoming mutual aid resources throughout the incident.
Question 6: Which radio interoperability solution allows agencies on different frequencies to communicate by retransmitting signals across channels?
- ISSI (Inter-RF Subsystem Interface)
- Cross-band repeater/patch system (Correct answer)
- P25 conventional channel
- Mutual Aid channel (VTAC/ITAC)
Correct answer: Cross-band repeater/patch system
A cross-band repeater or radio patch retransmits audio from one frequency or radio system to another, enabling agencies on incompatible systems to communicate.
Question 7: When documenting a mutual aid unit's activity in the CAD system, what is the MOST important data element the dispatcher must capture?
- The mutual aid unit's home agency radio identifier
- The unit's assigned task, location, and status changes with timestamps (Correct answer)
- The name of the mutual aid coordinator who approved deployment
- The estimated fuel consumption of the responding unit
Correct answer: The unit's assigned task, location, and status changes with timestamps
Capturing assigned task, location, and timestamped status changes ensures accurate resource tracking and supports post-incident reimbursement and documentation.
