What labeling is required for gas cylinders?

Gas cylinders must be properly labeled with accepted color-coding to ensure the safety of all personnel handling or working near these cylinders. Proper labeling is critical because it allows individuals to quickly identify the contents of the cylinder, which is essential for safe handling and use. Each type of gas is associated with a specific color-coding system, which provides immediate visual cues on what is inside the cylinder. This helps prevent dangerous mix-ups and ensures appropriate precautions can be taken based on the type of gas being used.

Using numeric codes or unlabeled cylinders poses significant safety risks, as it can lead to confusion and accidents, particularly in environments where multiple gases are in use. Additionally, optional labeling would compromise safety standards and could result in hazardous situations if workers cannot confidently identify the gases present. Proper, standardized labeling is not just a best practice; it is often mandated by safety regulations to promote a safe working environment.
