TS 11939

TS 11939 addresses safety rules for LPG refueling stations used to supply motor vehicles. Its technical focus is the safe arrangement of the station, the associated equipment, and the operating conditions needed to reduce the risks created by storing and dispensing liquefied petroleum gas under pressure. In practical terms, the standard is about making LPG vehicle refuelling infrastructure safe to install and operate in a public or semi-public service setting.

How LPG station safety is understood technically

An automotive LPG refuelling station is typically a coordinated system of storage vessels, pumps or dispensers, piping, safety accessories, electrical installations, and emergency arrangements. The standard’s scope is the establishment and safety requirements for these stations, so it is concerned with both the physical layout and the technical provisions that support safe operation. Compared with petrol or diesel dispensing, LPG requires special attention because it is handled as a pressurised fluid with significant vapour-release and ignition considerations, which makes separation, equipment selection, and control measures especially important.

What this document covers, and what it is supported by

• It covers LPG refuelling stations for motor vehicles; it should not be read as a general LPG storage standard for all installation types.
• The document uses the term LPG throughout, matching the subject matter of the standard.
• Referenced TS and EN standards support related areas such as fire protection, electrical safety, tank construction, and equipment suitability.
• The cited UKLPG and NFPA documents show the broader technical context used as reference material, not a claim that this standard reproduces those codes in full.
