What specific labeling must cylinders have?

The labeling on cylinders used for Compressed Natural Gas (CNG) is specifically designated to indicate that they are intended for CNG use only. This is crucial for ensuring safety and correct handling, as various gases can have different properties and hazards associated with them. Proper labeling helps differentiate CNG from other gases and substances, ensuring that individuals handling the cylinders are aware of the specific gas contained within.

Using CNG-specific labels helps prevent any potential mix-ups that could lead to dangerous situations. It's important for cylinders to clearly state the type of gas they contain, reflecting the standards set by regulatory organizations and safety protocols. This precise identification is vital in environments where multiple gases may be present, ensuring that personnel can respond appropriately in case of leaks or other emergencies related to gas usage or transport.
