About the course
What this course covers.
A gas monitor is only as good as the person who chose it, placed it and maintained it. Workers often carry a detector every day without knowing what type of sensor is inside, what it can and cannot detect, or why a skipped check matters. This course explains the equipment so the people relying on it can trust what it tells them.
It starts with handheld mechanical testers, devices that work without electricity to measure the concentration of a known gas, and how to use them correctly. It then covers continuous monitors for ongoing testing through the day and the four main sensor technologies: electrochemical, catalytic bead, infrared and photoionization, each designed to detect specific gases in different ways. Placement is next: fixed monitors, placed area monitors and personal monitors carried by workers, with the advantages and drawbacks of each.
Even the right monitor in the right place only works if it is tested and maintained, so the course covers the methods for testing and maintaining monitors. It closes on the hierarchy of hazard control, making the point that monitors are one part of protecting workers from dangerous gases, not a substitute for eliminating or controlling the source. A final exam checks understanding.

Why it matters for compliance
Where workers may be exposed to hazardous atmospheres, Canadian OHS rules require employers to assess the hazard, monitor where necessary, and train workers on the equipment they use. This course provides general knowledge of gas detection equipment; workers must also be trained on the specific monitors, manufacturer instructions and procedures at their site.
Common questions
Questions buyers ask
What sensor types does the course cover?
- Electrochemical, catalytic bead, infrared and photoionization sensors, and how each detects gases differently.
Does it teach me to use my company's specific monitor?
- No. It covers gas detection equipment in general. Follow the manufacturer's instructions and your employer's training for the specific monitor you carry.
How much does the course cost?
- The course is 49.99 CAD per seat. Ask our safety experts for 10 percent off your first course, or a free On-Track Safety corporate account for 20 percent off every course for the first three months.
Why does monitor placement matter?
- A fixed monitor protects an area, a personal monitor protects the worker wearing it, and an area monitor can be moved to where the work is. Each has trade-offs, and the course explains them.
Is a gas monitor enough to protect workers?
- No. The course places monitoring within the hierarchy of controls: eliminating or controlling the source comes first, and monitors are one layer of protection.
How long does it take?
- About 35 minutes, plus the final exam.
What is a handheld mechanical tester?
- A device that measures the concentration of a known gas without using electricity. The course explains how they work and how to use them correctly, alongside electronic continuous monitors.
Who should take gas detection training?
- Anyone who carries or relies on a gas monitor, including confined space entrants and monitors, and the supervisors and maintenance staff who choose, place and look after the equipment.
