TS 11939

TS 11939 is a safety standard focused on the safe operation, arrangement, and use of LPG refueling stations for road vehicles. Liquefied petroleum gas is a flammable fuel stored and dispensed under pressure, so station safety involves more than the dispenser itself: layout, leak control, fire-risk reduction, and the safe movement of vehicles and personnel are all part of the technical picture. This document covers safety rules for such stations and frames the safety requirements for this specific application.

Safety considerations in LPG refueling stations

In LPG refueling infrastructure, safety is assessed together with storage vessels, piping, dispensing equipment, ventilation, electrical equipment, and emergency arrangements. Because LPG is heavier than air, any release may accumulate near the ground, making ignition-source control, ventilation, and suitable equipment placement especially important. The standard’s subject is the management of these technical hazards in refueling stations intended for automotive use.

Technical scope and boundaries

• The subject is LPG refueling stations for road vehicles.
• The document covers safety rules, providing a safety-oriented framework for design, installation, and operation.
• It does not state a separate scope for other LPG uses in the supplied text.
• The document is referenced as equivalent to NFPA/ANSI 58:1998.

Standards in this area commonly establish a shared technical language for topics such as site arrangement, equipment suitability, operating procedures, and emergency readiness. TS 11939 should be understood as a technical reference for safe vehicle refueling with LPG. Its withdrawn status is relevant historically, but the title and scope clearly show that its subject is the safety of LPG refueling stations rather than LPG in general.
