Overview

EN 45545-7:2013 is a CEN European standard for fire protection on railway vehicles focused on flammable liquid and liquefied petroleum gas (LPG) installations. It defines safety objectives and technical requirements to prevent ignition and limit fire spread due to leakage or spray of flammable liquids/gases, in line with the general objectives of EN 45545‑1. The part excludes most technical liquids (e.g., hydraulic oil, transformer oil) except where guidance addresses spillages, leakage and spray generation, and it does not cover flammable gases other than LPG or vehicle preservation during fire.

Key Topics and Requirements

• Scope and objectives
  • Protect passengers and staff by preventing fires and limiting spread from liquid/gas leaks.
• General system requirements
  • Design assessments considering leakage paths, ignition sources, detection (LPG), and means to stop flow or contain/exhaust fuel.
  • Electrical bonding to rail via vehicle structure (per EN 50153).
  • Material certification (test reports/certificates per EN 10204).
• Tanks and tank location
  • Tanks must be protected from track debris and not sited in energy-absorption zones, passenger areas, luggage compartments or driver cabs.
  • Minimum wall thickness guidance (example: steel ≥2.0 mm for ≤2 000 dm3; aluminium ≥3.0 mm for ≤2 000 dm3; thicker for larger volumes).
  • Maximum fill level 90% with readable filling limit indicators; clear labelling consistent with safety data sheets (ISO 11014).
  • Required danger signage (Directive 92/58/EEC symbols).
• LPG installations (portable catering use)
  • Cylinders must remain within the same vehicle; coupling between vehicles prohibited.
  • Cylinder cabinets: sheet‑metal, upright, secured to meet crashworthiness (EN 15227).
  • Catering limits: up to two cabinets per vehicle, each with max two cylinders of 14 kg; if two cabinets, at least 8 m apart on opposite sides.
  • Cabinet ventilation: minimum 200 cm2 per cylinder at the bottom; vents must not be closable or obstructed.
• Pipework and fittings
  • Mount pipework above max tank fill level where possible, minimize joints, provide shut‑down valves close to tanks, and make flexible connections accessible for inspection.
  • Pressure regulators required for gas distribution systems.
• Operational and conformity
  • Includes requirements for operation instructions, inspection access, signage and conformity evaluation. Annexes cover required signs and links to EU directives.

Applications and Users

EN 45545‑7:2013 is relevant to:

• Rolling stock designers and system integrators specifying fuel and LPG systems (traction, auxiliary power, heating, catering).
• Railway vehicle manufacturers and component suppliers (tanks, valves, regulators, cabinets).
• Safety engineers, auditors and authorities responsible for vehicle fire safety compliance and conformity assessment.
• Maintenance teams responsible for inspection, labelling and safe operation of flammable liquid/gas installations.

4 General system requirements There shall be a design assessment, and the following factors shall be considered:  possible sources and paths of leakage, and for LPG installations, there shall be means of detecting any leakage;  flammability characteristics of flammable liquids and gases including the effects of any combustible or absorbing materials;
 possible ignition sources, including electrical faults, overheating of equipment, and malfunctioning of protective devices; SIST EN 45545-7:2013

In each area where a flammable liquid or a flammable gas might escape, there shall be means to reduce: a) the probability of ignition; and b) the consequences if ignition does occur. Some materials that have a fire prevention function may be operating at an elevated temperature as a result of being near equipment operating at high temperatures (e. g. exhaust pipe insulation). In such cases, degradation of the material could impair its ability to perform its function, and its propensity to ignite may be increased. Care shall be taken to ensure that such materials will not degrade in this manner. Metal containers and pipes fixed permanently on railway vehicles or stored movable containers shall be electrically bonded to the rail via the vehicle structure in accordance with EN 50153. For each metal used for flammable liquid or flammable gas installations, certified material test reports or test certificates according to EN 10204 shall be submitted. When selecting materials used in the vicinity of equipment which may generate flammable liquids or gases, care shall be taken to ensure that the material surface cannot absorb these species.
5 Flammable liquids and gas tanks 5.1 General Tanks shall be built, located or protected so that they or their piping cannot be punctured or fractured by debris thrown up from the track. Tanks shall not be installed in:  energy absorption zones;  passenger areas;  luggage compartments;  driver’s cabs. For tanks that are divided internally by partition walls, the complete tank shall fulfil these requirements. 5.2 Tanks for flammable liquids Tanks constructed to the following requirements are deemed to satisfy the minimum impact performance. If other materials are used, equivalent safety shall be demonstrated. The thickness of walls shall have a minimum according to Table 1. SIST EN 45545-7:2013

Tanks for flammable liquid shall be located and designed so that no ignition can occur at normal temperatures. The design of flammable liquid tanks shall ensure, as far as reasonably practicable, that during filling or draining or in the event of leakage from a tank or its pipe work, flammable liquids cannot:  come into contact with rotating machinery which might result in a spray;  be drawn into any device in suction e. g. ventilators and coolers;  come into contact with hot components, or electrical devices which may produce an electrical spark;  penetrate into layers of thermal or acoustic insulation material. Tanks for flammable liquids shall not be filled more than 90 % of their nominal volume. Filling limit indicators shall be provided. The output from a limit indicator device shall be easy to read from the filling position. To avoid confusion, the kind of appropriate flammable liquid shall be clearly labelled at or adjacent to the filling pipe of the tank. The labelling of the flammable liquid shall be given textual in accordance to safety data sheets according to ISO 11014. In the vicinity of the filling pipe the following danger signs shall be displayed:  danger sign P02 “No naked flames, no smoking” in accordance with Directive 92/58/EEC (see Figure A.1);  danger sign W01 “Warning of flammable liquids" in accordance with Directive 92/58/EEC (see Figure A.2).
