Summer Safety is a Gas, Gas, Gas!
What do all of these activities have in common? Compressed gases!
Whether for bug spray or beer, compressed gases make being outside even more enjoyable. We use propane for grills and lanterns and compressed air for blowing up tires and inner tubes. They use loads of them at the fair – helium for balloons, liquid nitrogen to make Dippin’ Dots®, and even Whac-A-Mole® at one time used air cylinders to raise and lower the moles.
While compressed gases can make our lives easier and fun, there are several hazards associated with them. All compressed gases pose a physical hazard because they are pressurized. Some are also poisonous, corrosive, extremely cold, or can cause fires and explosions.
Even non-flammable, non-toxic gases can cause oxygen deficiency and create an asphyxiation hazard. Cylinders of pressurized gases can range from small pocket size sprays to large cylinders that are used to heat and/or cool entire facilities. Improperly used, stored, or transported cylinders can cause major incidents. The gas can escape so fast that the cylinder becomes a rocket.
Many compressed gases pose multiple hazards, and should be used with extreme caution, both in the workplace and at home, regardless of the size or type of hazard.
OSHA Safety Standards for Compressed GasesThere are two standards that OSHA enforces when it comes to all compressed gases. First, 29 CFR 1910.1200, the Hazard Communication (HazCom) Standard requires that employees receive information and training on hazards they are exposed to.
Second, 29 CFR 1910.101, the Compressed Gases Standard, provides personnel with general requirements to follow when inspecting, handling, storing, or using compressed gases. In addition, if you deal with certain gases, such as acetylene, hydrogen, oxygen, or nitrous oxide, there are additional OSHA regulations that may apply to you.
Per the HazCom standard, OSHA divides gases under pressure into four categories:
- Compressed gas (e.g., helium)
- Liquified gas (e.g., propane)
- Dissolved gas (e.g., acetylene)
- Refrigerated liquified gas (e.g., liquid nitrogen)
US DOT Hazmat Regulations for Compressed GasesUS DOT hazardous materials regulations (HMR) define hazard class 2, compressed gases, in 49 CFR 173. The three divisions found in Class 2 are based on type of additional hazard the gas has, if any.
- Division 2.1: Flammable (e.g., acetylene and propane)
- Division 2.2: Non-flammable, non-poisonous compressed gas (e.g., helium and nitrogen)
- Division 2.3: Gas poisonous by inhalation (chlorine)
While there are fun applications for compressed gases, the main thing to remember is that the damage hazardous gases can do is no joke! Compressed gases are always dangerous, so learn how to store, handle, use, and ship them safely by taking Lion’s HazCom: Compressed Gases Online Course.
For training to inform and protect employees who work with other common hazardous materials, take a whack at any of our online OSHA/HazCom training courses.

Excellent class, super instructor, very easy to follow. No rushing through material. Would like to take his class again.
EH&S Facility Maintenance & Security Manager
Lion is my preferred trainer for hazmat and DOT.
I like the consistency of Lion workshops. The materials are well put together and instructors are top notch!
Permitting, Compliance & Environmental Manager
I have been to other training companies, but Lion’s material is much better and easier to understand.
Lion is at the top of the industry in compliance training. Course content and structure are updated frequently to make annual re-training enjoyable. I like that Lion has experts that I can contact for 1 year after the training.
Amazing instructor; real-life examples. Lion training gets better every year!
Having the tutorial buttons for additional information was extremely beneficial.
These are the best classes I attend each year. I always take something away and implement improvements at my sites.
The instructor was excellent. They knew all of the material without having to read from a notepad or computer.
The instructor was probably the best I ever had! He made the class enjoyable, was humorous at times, and very knowledgeable.
