TS 11939/T1

TS 11939/T1 is a TSE standard focused on safety rules for liquefied petroleum gas refuelling stations serving road vehicles. It addresses LPG automotive fuelling infrastructure, providing a safety-oriented framework for how such stations are handled, including the critical areas of storage, refuelling and station layout.

Why safety is distinctive in LPG refuelling stations

LPG is stored under pressure as a liquid and becomes a gas when released for use. In automotive refuelling locations, this makes not only the fuel’s flammability relevant, but also the behaviour of pressure vessels, leak potential, vapour accumulation and possible ignition sources. From a general technical perspective, LPG stations are designed by considering tanks, dispensing equipment, piping, valves, separation distances and emergency arrangements together. This standard is concerned with that safety framework for such facilities.

Technical frame of this document

• The subject is LPG refuelling stations for road vehicles.
• The document is safety-rule oriented; it is not a product-performance or formulation standard.
• NFPA 58 is given as the source standard and the technical basis linked to this document.
• The document was later withdrawn, so it should be treated as a historical standard.

In practice, standards of this kind create a common technical language for safe station operation. For LPG facilities, the aim is to control risks during fuel transfer and to keep the station’s components aligned within a coherent safety approach.
