You’re a dispatcher. What do you call right after an EMS call?
Picture this: a 911 caller says, “There’s a fire in the kitchen.” You’re on the line, heart racing, trying to keep calm. The first thing you do is dispatch EMS. But that’s not the end of the story. In the real world, you’re also pulling in a squad of other resources—firefighters, police, hazardous‑materials teams, even a mobile command center—almost simultaneously. If you miss one, the outcome can change. That’s why knowing exactly which resources to request in addition to EMS is as critical as any other skill in emergency response.
What Is “Resources in Addition to EMS”?
When we talk about additional resources, we mean every support unit that can help solve a scene faster, safer, and more efficiently. Think of the emergency scene as a complex puzzle: EMS handles the medical side, but the rest of the puzzle pieces—fire suppression, law enforcement, hazardous‑materials containment, structural engineering, and even public information—must fit together. Dispatchers are the glue that pulls them all together Simple, but easy to overlook..
The Building Blocks
- Fire and rescue units – for structural fires, vehicle extrications, and water rescues.
- Police or security – for crowd control, scene safety, and incident command.
- Hazardous‑materials (Haz‑Mat) – for chemical spills, gas leaks, or toxic exposures.
- Structural or engineering teams – for building stability assessments.
- Public information officers (PIOs) – to keep media and the public informed.
- Medical transport (ambulance, helicopter) – for patient care beyond the scene.
These aren’t just optional extras; they’re often mandatory based on the incident type and local protocols.
Why It Matters / Why People Care
You might wonder, “Why do I need to call for all these units? And isn’t EMS enough? ” The answer is simple: EMS alone can’t always handle the whole picture.
- Safety first – Firefighters can secure a burning building, police can control a crowd, Haz‑Mat can neutralize a chemical threat. Without them, EMS crews risk getting trapped or exposed.
- Efficiency – Each unit brings specialized tools. A single unit trying to do everything is slower and more dangerous.
- Legal and liability – Many jurisdictions mandate certain resources for specific incidents. Failure to deploy them can lead to fines or lawsuits.
- Outcome – Faster, coordinated response means more lives saved, less property damage, and a smoother recovery.
In short, the right resources can turn a chaotic scene into a controlled operation And that's really what it comes down to..
How It Works (or How to Do It)
Step 1: Gather Scene Information
The first call is all about data: location, nature of the incident, number of people involved, hazards, and any immediate threats. The more accurate the info, the better you can match resources.
- Ask open‑ended questions: “What’s happening?” “Are there any fires, chemicals, or structural concerns?”
- Confirm the address: Use GPS coordinates if possible.
- Note any special conditions: “Is it a school? A nursing home? A high‑rise?”
Step 2: Apply Dispatch Protocols
Every agency has a dispatch matrix that maps incident types to required resources. Familiarize yourself with:
- Incident categories (fire, medical, chemical, structural collapse, etc.).
- Resource thresholds (e.g., a fire in a residential building usually needs two engines; a chemical spill over 10 gallons requires Haz‑Mat).
- Priority levels (Level 1 = life‑threatening, Level 2 = urgent but not immediate).
Step 3: Pull the Right Units
Once you’ve matched the incident to its protocol, send out the units. A typical dispatch sequence looks like this:
- EMS – usually first on the scene.
- Fire engines or ladders – if there’s a fire or structural risk.
- Police or security – for crowd control, perimeter security, or suspect apprehension.
- Haz‑Mat – if chemicals or hazardous materials are involved.
- Engineering or structural – for building stability checks.
- Public Information Officer – if media presence is expected.
Use your dispatch software’s resource request function to queue each unit. If you’re on a manual system, make separate phone calls or send radio messages—speed matters.
Step 4: Confirm Arrival and Status
After units are dispatched, keep the line open:
- Ask for ETA: “When will the engines arrive?”
- Check for updates: “Has the Haz‑Mat team arrived?”
- Relay new information: If the scene evolves, update all units instantly.
This loop ensures everyone stays informed and can adjust their plans on the fly Worth knowing..
Common Mistakes / What Most People Get Wrong
-
Assuming EMS Is Enough
A lot of dispatchers default to calling EMS only, especially for “medical” calls. In reality, many medical incidents involve fire, hazardous materials, or structural hazards Small thing, real impact.. -
Delaying Resource Requests
Waiting for a “second look” before pulling a fire unit can cost precious minutes. Trust the initial information; you can always cancel if it turns out unnecessary. -
Misreading Protocols
Every agency’s dispatch matrix is different. Relying on memory or outdated charts leads to under‑ or over‑deployment. -
Neglecting Scene Safety
Failing to call police or Haz‑Mat for a potentially dangerous scene can expose first responders. -
Over‑Complicating the Call
Trying to cram every detail into one line can confuse the dispatcher. Keep it concise: “Fire in kitchen, chemical spill 5 gallons, 3 injuries.”
Practical Tips / What Actually Works
- Keep a quick‑reference cheat sheet of resource thresholds for your most common incidents. Stick it to the side of your screen or in your headset.
- Use a “first‑call” checklist that prompts you to ask for fire, police, Haz‑Mat, and engineering before sending EMS. A simple tick‑box system can prevent omissions.
- Practice scenario drills with your team. Simulate a chemical fire or a collapsed building and run through the dispatch process.
- use technology. Modern dispatch software can auto‑populate resource requests based on input fields. Set up templates for high‑risk calls.
- Stay updated on local regulations. New laws or ordinance changes can alter required resources for specific incidents.
- Build relationships with field units. Knowing the capabilities and limitations of each squad helps you make smarter dispatch decisions.
FAQ
Q: When should I call Haz‑Mat?
A: Call Haz‑Mat if there’s any indication of chemicals, gas leaks, or toxic substances—especially if the volume is above the local threshold (often 10 gallons or more) Easy to understand, harder to ignore..
Q: Do I need to call police for a medical call?
A: If the scene is potentially dangerous (e.g., a suspect, a scene of violence, or a crowded area), call police for safety and crowd control And that's really what it comes down to..
Q: How do I handle a call with incomplete information?
A: Gather what you can, use the protocol to pull the minimum required resources, and stay on the line to update as you learn more.
Q: What if all units are busy?
A: Prioritize based on the incident’s severity. If you can’t get a fire engine for a small kitchen fire, at least get a ladder or a police unit for perimeter control.
Q: Is it okay to cancel a unit after it’s dispatched?
A: Only if the situation changes drastically and the unit’s presence would be a liability. Communicate the cancellation immediately to the unit’s dispatcher.
Closing
Dispatching is more than just a phone call. Remember: the first call is your chance to set the tone. It’s a rapid decision‑making dance where every second and every resource counts. By mastering the art of calling the right units—EMS, fire, police, Haz‑Mat, engineering, and public information—you become the linchpin that keeps scenes safe, efficient, and ultimately, life‑saving. Use it wisely.
Some disagree here. Fair enough.
