What is the format required for marking on CNG labels?

The requirement for marking on CNG labels is to use a blue background with silver or white reflective luminous material. This specific format is crucial for ensuring that CNG vehicles are easily identifiable, especially in low-light conditions. The reflective qualities of the materials enhance visibility, making it easier for emergency responders and others on the road to recognize the presence of compressed natural gas, which is important for safety reasons. The blue color is standardized within the industry for clear communication and to prevent confusion with other types of fuel.

This adherence to specific labeling requirements helps avoid accidents and ensures that regulations are met. Proper marking plays a significant role in overall safety and operational effectiveness in environments where CNG is used.
