Gas cylinders are reliable sources of high-pressure gases, prized for their economic, safe, and readily available attributes. They find extensive applications in laboratories, pilot plants, and manufacturing due to the diverse nature of gases they can contain, ranging from inert to oxidizing, flammable, or toxic. Massive leaks of these gases can lead to irreversible harm to personnel and property. Hence, comprehensive understanding of gas cylinder-related knowledge is crucial to minimize improper handling and ensure their safe and rational use.
Recently, the Key Laboratory of Low-Carbon Catalysis and CO2 Utilization at the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, jointly with Lanzhou University, published an overview article on the introduction and safe use of gas cylinders in China. The article was published in ACS Chemical Health & Safety.
The article discusses the classification, color coding, composition, and identification of gas cylinders. It groups them based on the critical temperature of compressed gases, their physical state inside the cylinder, and chemical properties such as combustibility and toxicity. It also lists common coatings, markings, colors, and color rings on the outer surface of gas cylinders, along with components like cylinder stamps, caps, valves, and regulators. Storage conditions, transportation, operational methods, and inspection procedures for gas cylinders in Chinese university laboratories are emphasized, highlighting the dangers of improper gas cylinder use.
