Multi-County Winter Storm: Interoperability and Credentialing
A winter storm has dropped 14 inches of snow and caused widespread power outages across three counties. Two hospitals are on generator power; one has 20 hours of fuel. EMS is responding to 40 calls for chest pain and carbon monoxide exposure. Public works has 18 plows, but only 11 are operational; utility crews from two states are arriving without local credentials. A county sheriff is running traffic control, and a state emergency management representative is on scene. The counties have agreed to a single incident command but have not defined transfer of command or integrated communications. Fire, EMS, public works, and utilities are using four different radio systems. The state wants a common operating picture by 06:00.
1. How should the incident command apply the NIMS characteristics of common terminology and integrated communications across these disciplines?

The incident command should establish common ICS terminology and plain language for all positions. That means using standard functional titles such as Operations Section Chief, Division, Group, Staging Area Manager, and Resource Unit Leader, and avoiding agency-specific codes for resource requests, hazards, and locations. A common map grid or named sectors should be used for plow routes and hospital access.
For integrated communications, the Communications Unit Leader should develop a communications plan for the IAP. The plan should identify a common command channel, interoperability channels or patches, and backup methods such as cell phones or satellite phones where coverage allows. Each discipline should have a designated supervisor who monitors the common command channel while maintaining internal tactical channels. A test of the plan should occur before the 06:00 briefing.
The reasoning is that common terminology and integrated communications are not paperwork; they determine whether a plow can be redirected to a hospital fuel delivery or whether EMS and fire arrive at the same cardiac call. With four radio systems, the IC must create a single command net and a clear communications plan, not assume that co-location solves the problem.
2. What should be done about arriving utility crews without local credentials, and which NIMS resource management processes apply?
Read the worked answer
The incident should apply credentialing, resource typing, check-in, and accountability. Arriving utility crews should not be turned away automatically if they are needed, but they should not be assigned without verification. The Planning Section’s Resource Unit should check them in, record crew size, skills, equipment, and employer, and verify identity and qualifications through the utility liaison or state emergency management. If local credentials are missing, command should use a just-in-time verification process with the utility’s representative and document the exception.
Resource typing helps command understand what the crews can do, such as line crews, tree crews, or fuel delivery. The crews should then be assigned through Operations, not self-deploy to hospitals or substations. A staging area manager should track arrival and departure.
The reasoning is that credentialing is a safety and accountability control, not a border-control exercise. Command must balance the urgent need for power restoration with the risk of unverified crews touching energized lines or blocking snow routes. Documenting the exception protects the incident and the workers.
3. Describe the key elements of a transfer of command briefing if the IC changes at 06:00.
Read the worked answer
A transfer of command briefing should be complete enough that the incoming IC can assume authority without restarting the response. It should cover the current situation and objectives; the incident organization and key personnel; resources assigned, en route, and needed; the current IAP and communications plan; safety issues, including generator carbon monoxide, downed lines, and road conditions; hospital generator fuel status; and the status of the 40 EMS calls.
The briefing should also include the incident history, decisions made, unresolved issues, and the planned 06:00 operational period. The outgoing IC should identify the hospitals at risk, the plow status, the utility credentialing exceptions, and any political or intercounty agreements. The incoming IC should confirm receipt of the briefing and announce the transfer over the command channel. The transfer should be documented with time and names.
The reasoning is that transfer of command is a NIMS management characteristic because continuity of command is a safety function. In a multi-county, multi-discipline operation, an incomplete briefing can cause duplicated resource requests or loss of situational awareness at the exact moment the state expects a common operating picture.
