Question: 1 / 400

What must a hose used for CNG service be distinctly marked with?

Manufacturer's name, CNG service, and working pressure

A hose used for CNG service must be distinctly marked with the manufacturer's name, the designation of "CNG service", and the working pressure. This marking is crucial for safety and compliance with regulations. The manufacturer's name ensures that the hose can be traced back to its source, allowing for quality assurance and accountability. The indication of "CNG service" specifies the intended use of the hose, informing users that it is suitable for handling compressed natural gas, which has specific material and pressure requirements. Additionally, marking the working pressure is vital for safety, as it indicates the maximum pressure the hose is designed to handle, thereby preventing the risk of failure or accidents during operation. Distinct marking helps prevent mishandling and ensures that proper equipment is always used when dealing with CNG, which is essential for both safety and regulatory compliance.
