With a BullEx GasTrainer™ system, firefighters can train to confidently make critical decisions responding to HazMat IDLH emergencies through high-impact hands-on training.

Designed to replicate a four-gas meter, the GasTrainer system simulates and “detects” gas clouds and leaks that can be set in realistic scenarios where firefighters are most likely to respond. By detecting, displaying levels and alarming in real time, the GasTrainer system challenges students to interpret and react to a potential gas leak.

Take your training out of the classroom and into the real word with the GasTrainer system from BullEx.



Replace paper and verbal command training with actual active training utilizing tools on-site where dangers may be present

No exposure to IDLH environments necessary, no need for respiratory protection to train

Adjust alarm levels and intensity settings to create various emergency scenarios

Simulates four gases most common to first responder emergencies (Oxygen (O2), Hydrogen Sulfide (H2S) or Carbon Monoxide (CO) and LEL

Instructor controlled
Monitor and control the entire training scenario while on the scene

Train anywhere, anytime – indoors or out


The GasTrainer was developed to safely simulate situations in which the use of a four-gas meter would be required. The GasTrainer can simulate gas leaks/clouds without the hazards of using potentially lethal gases. Instead, electronic transmitters (GasSource emitters) are positioned and used to simulate a gas leak. By varying the position of the emitters and adjusting the settings, it is possible to simulate a variety of HazMat situations, ranging from small leaks to large vapor clouds.

The GasTrainer system is comprised of electronic gas source emitters, a student “gas detector” unit and an instructor unit that allows the trainer to control the scenario and observe the readings on the student unit.

GasSource Emitters can be placed anywhere a potential gas leak may occur, and simulate a leak of one of the four most common gases (Oxygen (O2), Hydrogen Sulfide (H2S) or Carbon Monoxide (CO) and LEL). Automatically simulate gas level behavior, and utilize the instructor’s unit to manually adjust and incorporate the other three gases into the simulation.  The Student Unit and Instructor Unit communicate with each other using a wireless link. The Student Units will respond to the Instructor Unit’s settings for both the default and manually adjusted gases.

The trainee, using the Student Unit, works to determine where the source of the leak is using the gas level readouts on the unit. An alarm sounds if the measured value exceeds a preset value indicating potentially dangerous levels, just like real gas meters.

The trainer, using the Instructor Unit, can create a variety of training scenarios that determine what readout the student unit displays by setting alarm levels, adjusting the gas being monitored and manually increasing or decreasing gas readings to provide additional training challenges. Two separate alarm levels can be set by the instructor per gas; one minimum level and one maximum level. The instructor simultaneously receives the same alarm signal if one of the alarm values is exceeded on the Student Unit.

A Detachable Metering Wand allows students to train on metering confined spaces and locating point source emissions.



Emergency Response
Trainees learn how specific atmospheres (the presence or lack of certain gases) will determine the level of emergency response.

Locate emission sources
Teach trainees how to identify and find the source of a gas leak in order to determine the proper response (simple valve closure or evacuation).

Establish safety perimeters
Learn the proper distances to maintain from certain hazardous environments, understand what respiratory protection and other PPE is required at certain gas concentration levels.


Detachable Metering Wand
A detectable remote sampling wand that allows students to meter confined spaces or to search for gas sources in limited access areas such as confined spaces

Compressed gas cylinder prop with integrated electronics that create a hissing sound effect when the valve is opened

Leaking Propane Tank
Propane cylinder prop (20 lb.) with integrated electronics that create a hissing sound effect when the valve is opened

HazMat Placard Kit
Includes a complete set of magnetic Hazardous Materials placards, a UN number sign and an NFPA 704 diamond

I wanted to take this opportunity to give feedback on our GasTrainer System package, Leaking Propane Tank Prop and HazMat Placard Kit.

In February of 2010 we received our training tools package. This was a significant investment in a single piece of training equipment. The original decision to purchase was based on the lack of practical hands-on training for staff and students in the use of four-gas monitors. Most of the training revolved around verbalizing scenarios and simulated reading changes.

Annually, our department works in concert with several other local departments to conduct a firefighter academy for new recruits. Part of the curriculum is HazMat Operations Responder Training. Utilizing the GasTrainer System with the remote emitters and the Leaking Tank Prop during HazMat training has been a quantum leap ahead for our students. Previously the orientation consisted of the students being shown a meter followed by lecture. The GasTrainer System and props have been integrated into the training and they utilize them on scenarios presented to them in class. From initial scene assessment, scene safety, defensive actions to decon, they utilize the meter, just as they would on an actual call.

We have already noticed an increase in the confidence when utilizing four-gas monitors on the part of our staff and students. Being able to remotely alter readings on the student monitor creates a more realistic environment. Firefighters retain skill information better if they hear, see and do. This tool provides all three.

Three of the most impressive things about the GasTrainer System are:

  • The number of “Ah Ha!” moments experienced by seasoned and new firefighters when working with the simulator, especially for the first time.
  • Our department educators have been able to utilize the unit with minimal training.
  • The equipment is “firefighter resistant” which means it takes a beating and keeps working.

The equipment has met and exceeded our expectations and we look forward to many years of use.
