Three Rivers Dynamics

Many of the fires we face today are ventilation limited.
Open a door. Break a window. Add oxygen. Conditions can change fast.
Three Rivers Dynamics props let you see that cause and effect on a smaller, repeatable scale.
Read the smoke. Watch the flow path. Open the door. Open the window. See what changes—and understand why.
Train smart. Get the reps.
Observation is your last chance at preparation.

Observation is your last chance at preparation—and conditions can change fast.
Train for what happens next.

Which one would you use?
Both modes show the convection currents coming from the stairwells—but look at how differently they present the environment.
Does one give you more detail?
Does one wash out the screen more than the other?
What information are you actually looking for?
Each TIC mode has a purpose. Sometimes you're using the camera for situational awareness. Other times, you're using that information to help make a decision.
Knowing how to operate a TIC is one thing. Understanding what the image is telling you is another.
Get your reps. Know your camera. Know your modes.
Observation is your last chance at preparation.

Started the day out my pumping for an essentials class. Finished the day catching a job an hour after they were certified. Proud to moment with these young men.

Basement fires. Balloon-frame construction. Hidden fire travel.

We talk about them in the fire service—but seeing how fire actually moves through a structure changes the conversation.

Our props incorporate balloon-frame construction and stairwells to demonstrate how fire can rapidly travel throughout a structure—and how poorly coordinated ventilation can have deadly consequences.

See the flow path. Read the smoke. Understand where the fire is going before you commit.

Train smart. Train with purpose.

🔥 Observation is your last chance at preparation.

Observation is your last chance at preparation.

Before you make entry, what is the building telling you?

What’s the smoke telling you? What color is it? How fast is it moving? Is it turbulent? What heat signatures are showing up on your TIC?

These are all things we need to slow down, recognize, and process before crossing the threshold.

The fireground isn’t the place to see these indicators for the first time. Get the reps in during training so recognition becomes second nature when it matters most.

Train. Observe. Recognize. Repeat. 🔥


Training props built to help firefighters understand fire behavior through repetition and realistic observation.

On the right: a brand-new RES 1 ready to start its journey.
On the left: one of our demo units with hundreds of burns and plenty of miles under its belt.
During delivery, we run through our Train-the-Trainer demonstration using one of our seasoned demo props. We want our customers to see firsthand how these units operate after repeated burns—not just when they're brand new.
Because confidence in your training equipment shouldn't end after the first few burns. You should know that years and hundreds of training evolutions later, your prop will still be ready to go to work.
Built to train. Built to last. Built for the fire service.
