Ever walked into a chaotic scene—a wildfire blazing on the horizon, a hurricane‑ripped town, or a chemical spill choking a highway—and wondered how anyone ever pulls it together?
Day to day, turns out there’s a playbook humming behind the scenes, and it’s called IS‑700. B.
If you’ve never heard the code before, you’re not alone. That said, most people only see the result—roads closed, shelters opened, news anchors talking nonstop. Because of that, the short version is that IS‑700. B is the backbone of the National Incident Management System (NIMS), the “how‑we‑do‑it” guide that lets dozens of agencies speak the same language when disaster strikes.
In practice, that means a firefighter in Oregon can coordinate with a public health official in Florida without a dozen emails asking, “What do you mean by ‘operational period’?”
What Is IS‑700.B
Think of IS‑700.Day to day, b as the rulebook for the National Incident Management System, but stripped down to the essentials any responder can grab and run with. It’s a 30‑page PDF that lives on FEMA’s website, and it breaks down NIMS into bite‑size concepts: command structures, resource typing, communications, and the whole “incident action planning” workflow.
The Core Idea: A Common Operating Picture
At its heart, IS‑700.That’s just a fancy way of saying everyone sees the same map, the same priorities, and the same timeline. B says every incident—no matter how small—needs a common operating picture. When a tornado touches down in Kansas, the local sheriff, the state Emergency Operations Center, and the Red Cross all pull from the same playbook. No one’s left guessing which road is blocked or which shelter is full.
How It Fits Into NIMS
NIMS is the umbrella; IS‑700.B is one of its most used panels. NIMS has several parts: resource management, communications, preparedness, and the Incident Command System (ICS). IS‑700.B stitches those pieces together with a focus on standardization. If NIMS is the kitchen, IS‑700.B is the recipe that tells you when to add the salt, when to turn the heat up, and how long to let it simmer And that's really what it comes down to..
Why It Matters / Why People Care
Disasters don’t care about jurisdictional lines. A wildfire can leap from a county into a neighboring state in minutes. Without a unified system, you get duplicated efforts, missed resources, and—worst of all—people left in danger.
Real‑World Consequences
Remember Hurricane Harvey in 2017? Early on, multiple agencies sent rescue boats to the same flooded neighborhood while another area waited for help. The lack of a shared incident action plan cost lives and inflated the response budget. Which means after that, critics pointed straight at gaps in NIMS training and the inconsistent use of IS‑700. B.
This is where a lot of people lose the thread.
The Legal Angle
Federal funding for emergency management often hinges on compliance with NIMS. If a state can’t prove it’s using the standard incident management system, it may lose grant money. That’s why you’ll see “NIMS‑compliant” stamped on a lot of after‑action reports.
The Human Side
On the ground, responders talk about “the feeling of being on the same page.” That feeling comes from following the same terminology, the same planning cycles, and the same reporting forms. It reduces stress, cuts down on miscommunication, and—let’s be honest—makes the job a bit safer Less friction, more output..
How It Works
Alright, let’s get into the nuts and bolts. Also, iS‑700. On the flip side, b isn’t a mystery; it’s a step‑by‑step guide that anyone can follow once they’ve done the basic NIMS training. Below is the typical flow from the moment an incident is reported to the final after‑action review Took long enough..
1. Activation and Initial Notification
- Trigger – An event meets a predefined threshold (e.g., wind speeds over 74 mph, a hazardous material release).
- Notification – The incident commander (IC) alerts the agency’s Emergency Operations Center (EOC) using the Incident Notification Form (IN‑F).
2. Establishing the Incident Command Structure
- Command Staff – The IC appoints a public information officer, safety officer, and liaison officer.
- General Staff – Four sections roll out: Operations, Planning, Logistics, Finance/Administration.
Pro tip: Keep the staff list on a laminated card. In the heat of the moment, you’ll thank yourself for not having to hunt down a spreadsheet Which is the point..
3. Developing the Incident Action Plan (IAP)
- Operational Period – Usually 12‑hour blocks; the plan is reviewed and updated at each transition.
- Planning Process – Situation Brief → Resource Assignment → Objectives → Strategies → Tactics → Safety Message.
Example IAP Snapshot
| Element | Detail |
|---|---|
| Incident Objectives | Secure the flood‑affected downtown area, restore power to critical facilities |
| Operational Period | 0800–2000 hrs |
| Assignments | 3 HazMat teams, 2 EMS units, 1 UAV for aerial survey |
| Safety Concerns | Electrical hazards, contaminated water, low visibility |

4. Resource Typing and Mutual Aid
IS‑700.B defines resource types (e.Day to day, g. , Type 1–5 for fire engines) so that a request for “Type 2 engine” means the same thing nationwide. When a state needs help, it sends a Resource Request Form (RRF) that lists the exact type, quantity, and duration Which is the point..
5. Communications and Information Management
- Common Radio Frequencies – 10‑meter band for inter‑agency voice, plus a dedicated data channel for situational reports.
- Message Formats – Use the Incident Status Summary (ISS) template: “Current Incident Size: 3 km radius, 150 structures threatened.”
6. Demobilization and After‑Action Review
When the incident winds down, the IC initiates demobilization: resources are released, equipment is inspected, and personnel complete a “lessons learned” worksheet. The after‑action report (AAR) is then uploaded to the NIMS portal for future reference Worth keeping that in mind..
Common Mistakes / What Most People Get Wrong
Even with a solid guide, people stumble. Here are the pitfalls that keep showing up in after‑action reports.
Skipping the Planning Cycle
A lot of agencies think the “planning” part is optional once the command structure is set. In reality, the planning section is the engine of the IAP. Forgetting to update objectives each operational period leads to outdated priorities and wasted effort.
Mislabeling Resources
You’ll hear the term “resource typing” a lot, but many responders just write “fire truck” on a request. That sounds fine until the receiving agency thinks you need a Type 1 engine when you actually have a Type 3. The result? A bigger, more expensive asset shows up, or worse, the right one never arrives Most people skip this — try not to..
Over‑Complicating Communications
People love acronyms, but when you start tossing “ICS‑209‑R,” “EOC‑SITREP,” and “POS‑UAV” into the same radio transmission, you lose clarity. The rule of thumb: one acronym per sentence, and always define it the first time you use it Turns out it matters..
Ignoring the Safety Officer
The safety officer is often the first to be reassigned when resources get thin. That's why that’s a mistake. The safety officer’s job is to keep the whole operation from turning into a secondary incident Most people skip this — try not to..
Practical Tips / What Actually Works
You’ve seen the theory, now let’s talk about the stuff that makes a difference on the ground.
-
Print the First Page of IS‑700.B and tape it to every command post board. The first page is a quick‑reference flowchart—no one wants to flip through a PDF when a siren sounds That's the part that actually makes a difference. But it adds up..
-
Run a 15‑minute tabletop drill before every shift change. Walk through the activation steps, assign roles, and practice the IAP template. It feels like a waste of time until the real incident hits.
-
Use a “Resource Tracker” app that mirrors the NIMS resource typing fields. Many agencies have built simple spreadsheets, but a mobile app lets you see at a glance which Type 2 engines are en route.
-
Assign a “Communication Champion.” This person monitors the radio traffic, logs all SITREPs, and makes sure every message follows the standard format. One champion can cut miscommunication by half.
-
Debrief with the whole team—not just the command staff. Front‑line responders often notice gaps that leaders miss. A quick 10‑minute “what went well/what could improve” huddle after each operational period is pure gold.
FAQ
Q: Do I need a special certification to use IS‑700.B?
A: No formal certification is required, but most agencies expect you to have completed the basic NIMS/ICS 100–400 courses. Those courses walk you through the same terminology and structure.
Q: How does IS‑700.B differ from the full NIMS manual?
A: IS‑700.B is a concise, user‑focused supplement. The full NIMS manual runs hundreds of pages and includes policy, legal, and technical annexes. IS‑700.B pulls out the day‑to‑day operational steps most responders need.
Q: Can IS‑700.B be used for non‑disaster incidents, like a large public event?
A: Absolutely. The same command and planning structures apply to any multi‑agency operation—think a marathon, a music festival, or a big construction project.
Q: What’s the best way to keep the IAP updated during a fast‑moving incident?
A: Assign a dedicated planner in the Planning Section whose sole job is to capture real‑time changes and re‑issue the IAP at each operational period transition That's the whole idea..
Q: Is there a digital version of the Incident Action Plan template?
A: Yes, FEMA provides an editable Word and PDF version on their website. Many agencies have converted it to an online form that auto‑populates fields from their resource database.
When the sirens wail and the first responders rush out, the real magic isn’t in the gear they wear—it’s in the shared language they use. Day to day, iS‑700. B may look like a dry PDF, but it’s the thread that stitches together fire, law enforcement, public health, and volunteers into a single, effective response And that's really what it comes down to..
So the next time you see a headline about a disaster response, remember the quiet work happening behind the scenes: a command post humming to the same beat, a resource list that means the same thing across state lines, and a plan that gets updated every few hours. In practice, that’s the power of IS‑700. B, and that’s why it matters to anyone who’s ever wondered how chaos turns into coordinated action.
