Give Students Real Readings, Not Narration
Walking a crew through an atmospheric monitoring scenario usually means someone holds a real meter while the instructor says what it would be showing. Students hear a number instead of reading one, and the instinct you are trying to build — look at the display, interpret it, act — never gets exercised.
This simulator puts a working 4- and 5-gas monitor on the student’s own device. You control what it says from yours.
Opens in a new tab. The simulator runs full-screen and outside the site layout so nothing interferes with the display or the controls.
What the instructor controls
- Up to four monitors at once. Run separate readings for separate crews, or give an entry team and a backup team different atmospheres in the same evolution.
- Presets for planned scenarios. Step the atmosphere through a predetermined sequence so an evolution runs the same way every time you teach it.
- Live adjustment of any reading. Change O2, LEL, CO, H2S, or a fifth sensor independently, in real time, in response to what the crew actually does.
- Immediate feedback. Because you can see what the student sees, you can correct interpretation errors at the moment they happen instead of at the debrief.
Running a session
- Open the simulator on your device and choose the instructor view.
- Have students open the same link on their phones or tablets and choose the student view.
- Assign each student device to one of your four monitors.
- Load a preset or set readings manually, then run your evolution. Changes appear on student screens as you make them.
Where it fits
Confined space entry, hazmat awareness and operations, below-grade rescue, CO alarm response, tank and vessel work, and any evolution where the decision to enter, ventilate, or withdraw should come from a number on a screen rather than from the instructor’s voice.
Pairs well with the HazMat Awareness prep tools and the confined space rescue resources. Free to use, no account required.
