TS 13660

TS 13660 is a standard that sets rules for workplace arrangement, operating practices, employee qualifications, and safety in compressed natural gas (CNG) filling plants. CNG filling plants are technical and operational facilities where natural gas is transferred under high pressure for vehicle refuelling or similar uses; because of that, the layout of the plant, the organization of personnel, and the safety regime must be considered together.

Plant structure and operating practice

The standard focuses on aligning the physical characteristics of the filling plant with its management approach. In general technical terms, CNG facilities rely on proper equipment layout, safe gas routing, access control, emergency preparedness, and disciplined maintenance. The purpose is to reduce the risks inherent in working with compressed gas and to keep the refuelling process under controlled conditions.

Personnel competence and safety

The standard also covers employee characteristics and safety matters. In practical terms, this points to the importance of having personnel who are suitably informed, attentive, and organized for the tasks they perform in a CNG filling plant. In the broader technical context, safety in pressurized gas systems is closely tied to correct operating procedures, appropriate training, equipment awareness, and the ability to respond promptly and correctly to abnormal situations.
