BullEx has developed the GasTrainer™ system to provide your employees with hands-on experience with a four-gas meter, without the dangers of an actual hazard.

Designed to simulate and “detect” the four most common gases – Oxygen (O2), Hydrogen Sulfide (H2S) or Carbon Monoxide (CO) and LEL – the GasTrainer system can be used in work areas where hazmat dangers actually exist, such as chemical storage facilities or near HVAC equipment.

With the GasTrainer system, employees can learn how different gases behave, how to locate emission sources, what level of each gas is dangerous and how to establish safety perimeters in the event of a hazardous situation. You decide what level of training your employees need for your facility’s safety program.



Conduct effective gas detection training without the threats of actual hazardous environments or the need for respiratory protection.

Train anytime in places where an actual gas leak may occur.

Programmed to train on the four gases most common to first responder emergencies(Oxygen (O2), Hydrogen Sulfide (H2S) or Carbon Monoxide (CO) and LEL).

Instructor controlled
Instructors have full control of every aspect of training, including what the trainee sees on the hand-held training meter, using the instructor’s unit. This allows trainees to get a more comprehensive understanding of how to read and interpret a real gas meter..

Adjust alarm levels and intensity settings to set various emergency scenarios.


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 observe what the student is doing.

GasSource Emitters, which can be placed anywhere a potential gas leak may occur, simulate a gas leak source of one of the four most common gases (Oxygen (O2), Hydrogen Sulfide (H2S) or Carbon Monoxide (CO) and LEL. Instructors can choose which gas leak to simulate, and can also manually adjust any of the other gas levels to incorporate them 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, tries to determine where the source of the leak is using the gas level readouts on the unit, and must correctly respond to the risk.  It measures the signal strength of the emitters that simulate one of the four possible gases. An alarm sounds if the measured value exceeds the preset alarm value.

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 even 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) affect 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


Metering Wand
This detachable wand that allows students to meter and search for gas sources in limited access areas and 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

Safety Training and Consultations – International LLC Richard Shoaf, Senior VP of Operations

STCI has enhanced its quality of training with the addition of BullEx simulators for HazMat training for public safety and general industry.

Q)    How did you hear about BullEx Digital Safety?
A)    “Safety Training and Consultations – International has used other BullEx products in training.”

Q)    How long have you been with Safety Training and Consultations – International?
A)    15 Years

Q)    How long have you been conducting training?
A)    22 years

Q)    How did you conduct gas detection training prior to purchasing the BullEx GasTrainer?
A)    Before purchasing GasTrainer, we used stimulants and other “live” chemical materials for detector response.
Q)    What benefits have you received through the use of the BullEx GasTrainer?
A)    The BullEx Gas Trainer allows students to see a realistic response of instruments in a safe training environment while the instructor is able to monitor their reading for discussion in post scenario discussions. These tools can be used in our public safety as well as general industry training at many levels (Awareness through Specialist).

Q)    How have the BullEx HazMat training tools enhanced your training scenarios?
A)    During our HazSWAT training, our tactical officers are able to see a real     response to the entrance of a concentrated (simulated) hazardous material in a confined area. We could not simulate the concentration of such a hazard prior to our acquisition of this tool. Additionally, the HazardTank used in our mobile drug lab scenarios allowed us to simulate a leaking tank.

Q)    What three to four words would you use to describe GasTrainer?
A)    Excellent training tool!

Q)    Would you recommend the BullEx GasTrainer? Why or why not?
A)    Without a doubt.
