Training Objectives

Learn the three main types of compressed gases and their properties
Identify the hazards of compressed gas cylinders
Practice safe storage, transport, and use of gas cylinders
Learn the dangers of liquefied gases, cryogenic risks and asphyxiation
Choose and use the right PPE for compressed gas tasks

Course Overview

Compressed gas cylinders are a vital tool in the trades, used daily by welders, HVAC technicians, plumbers, and mechanics. But with gases pressurized at over 2500 psi, they also carry serious hazards. Compressed Gas Safety: For the Trades is designed to help you understand not just the rules, but the reasons behind them—so you can work with confidence and respect for the power in your hands.

You’ll learn to identify the three main gas types—liquefied, non-liquefied, and dissolved—and why cylinder labels are the only reliable way to confirm contents. The course covers both chemical hazards, such as flammability and asphyxiation, and physical hazards, like unsecured cylinders becoming dangerous projectiles. It also stresses critical practices for storage, transport, and use, from proper securing methods to keeping oxygen fittings free of oil and grease.

Special attention is given to liquefied gases, which can cause severe frostbite and displace oxygen in confined spaces. You’ll see why selecting the right PPE—goggles, face shields, and loose gloves—is essential for protection. By mastering safe handling practices and understanding the risks, you’ll be able to control hazards and ensure you return home safe after every shift.

This program is available with Spanish and French closed captions.

No Worries. Here’s Some Helpful Info.

What are the three types of compressed gases?


The three types of compressed gases are liquefied gases, non-liquefied gases and dissolved gases.


Why is it dangerous to handle an unsecured cylinder?


An unsecured cylinder that falls and has its valve snap off can become an unguided missile with enough force to launch through concrete walls, causing fatal injuries.


What are the specific dangers of liquefied gases like refrigerants?


Liquefied gases can cause severe, deep-tissue frostbite almost instantly upon contact due to auto-refrigeration. They can also pose an asphyxiation hazard as they are often heavier than air and displace oxygen.


What's the cardinal rule for using oxygen cylinders?


The cardinal rule is to keep all oil and grease away from oxygen fittings, as pressurized oxygen can cause these substances to spontaneously and violently combust.


Why shouldn't I lift a cylinder by its valve cap?


The valve protection cap is designed to protect the delicate valve assembly, not to support the cylinder's weight. Lifting by the cap can cause it to break off, potentially dropping the cylinder and damaging the valve, which can turn it into a missile.
