How to Properly Classify Gas Cylinders for Safety and Compliance

In the industrial, medical, and research sectors, gas cylinders play a vital role in storing and transporting various gases. However, improper classification of these cylinders can lead to safety hazards and compliance issues. This article will guide you on how to properly classify gas cylinders to ensure both safety and compliance.

Understand the Types of Gas Cylinders

Before classifying gas cylinders, it’s essential to understand the different types. Compressed gas cylinders, liquefied gas cylinders, and dissolved gas cylinders are the three main categories. Compressed gas cylinders store gases under high pressure, while liquefied gas cylinders contain gases that are liquefied under pressure. Dissolved gas cylinders, on the other hand, store gases dissolved in a solvent.

Identify the Gas Type

The first step in classifying gas cylinders is to identify the type of gas they contain. Different gases have different chemical properties, hazards, and handling requirements. It’s crucial to know the exact gas type to ensure proper handling and storage. Labels and markings on the cylinders often provide this information.

Determine the Pressure Rating

Gas cylinders are designed to withstand a specific pressure range. The pressure rating indicates the maximum pressure the cylinder can safely contain. To properly classify gas cylinders, you need to determine the pressure rating. This information is usually stamped on the cylinder’s shoulder or neck.

Assess the Size and Capacity

The size and capacity of gas cylinders are also important considerations for classification. Larger cylinders can store more gas, but they may require special handling and storage arrangements. It’s crucial to assess the size and capacity of the cylinders to ensure they meet your needs and comply with safety regulations.

Apply Color Coding

Color coding is a widely used method for visually identifying the type of gas in a cylinder. Standard color codes are assigned to different gases to provide quick and easy identification. Applying the appropriate color code to your gas cylinders can help ensure correct handling and reduce the risk of mix-ups.

Label and Mark the Cylinders

Properly labeling and marking gas cylinders is essential for safety and compliance. Labels should include information such as the gas type, pressure rating, manufacturer’s information, and safety instructions. Markings such as expiration dates, inspection dates, and hazard symbols should also be applied to the cylinders. Ensure that all labels and markings are clear, legible, and up-to-date.

Follow Industry Standards and Regulations

Different industries have their own standards and regulations for gas cylinder classification. It’s crucial to be familiar with the specific standards and regulations applicable to your industry. This will ensure that your gas cylinders comply with all relevant safety and compliance requirements.


Proper classification of gas cylinders is crucial for ensuring safety and compliance in various industries. By understanding the different types of gas cylinders, identifying the gas type, determining the pressure rating, assessing the size and capacity, applying color coding, labeling and marking the cylinders, and following industry standards and regulations, you can ensure that your gas cylinders are classified correctly and safely. Remember, safety always comes first, so be sure to handle and store your gas cylinders with care.
