Railway applications - Fire protection on railway vehicles - Part 1: General

The measures and requirements specified in EN 45545 are intended to protect passengers and staff in railway vehicles in the event of a fire on board. EN 45545 specifies:
- fire protection measures for railway vehicles;
- verification methods for these measures.
The protection of passengers and staff is essentially based on measures to:
- prevent fires occurring due to technical faults and due to equipment design or vehicle layout (Part 1, Part 4, Part 5 and Part 7);
- minimise the possibility of ignition of materials installed on railway vehicles due to accidents or vandalism (Part 1 and Part 2);
- detect a fire should it occur (Part 6);
- limit the spread of fire by specification of materials according to their operational categories (Part 2) and by measures for containment (Part 3);
- minimise the effects of fire in terms of heat, smoke and toxic gases on passengers or staff through the specification of materials installed on railway vehicles (Part 2);
- control and manage a fire, for example by means of fire detection, suppression and/or emergency energy shut down (Part 6). The ultimate objective in the event of a fire on board is to allow passengers and staff to evacuate the railway vehicle and reach a place of safety. The present European Standard describes the measures to be taken in the design of the vehicles in the context of the infrastructure on which they operate. It is not within the scope of EN 45545 to describe measures that ensure the preservation of the vehicles in the event of a fire beyond what is required to fulfil the objective to protect passengers and staff. This European Standard is valid for railway vehicles as defined in Clause 3. Freight transportation vehicles are not covered by EN 45545. This part of EN 45545 covers:
- principal definitions;
- Operation Categories;
- Design Categories;
- fire safety objectives;
- general requirements for fire protection measures and their evaluation of conformity.

1 Scope
The measures and requirements specified in EN 45545 are intended to protect passengers and staff in railway
vehicles in the event of a fire on board.
EN 45545 specifies:
 fire protection measures for railway vehicles;
 verification methods for these measures.
The protection of passengers and staff is essentially based on measures to:
 prevent fires occurring due to technical faults and due to equipment design or vehicle layout (Part 1,
Part 4, Part 5 and Part 7);
 minimise the possibility of ignition of materials installed on railway vehicles due to accidents or vandalism
(Part 1 and Part 2);
 detect a fire should it occur (Part 6);
 limit the spread of fire by specification of materials according to their operational categories (Part 2) and
by measures for containment (Part 3);
 minimise the effects of fire in terms of heat, smoke and toxic gases on passengers or staff through the
specification of materials installed on railway vehicles (Part 2);
 control and manage a fire, for example by means of fire detection, suppression and/or emergency energy
shut down (Part 6).
The ultimate objective in the event of a fire on board is to allow passengers and staff to evacuate the railway
vehicle and reach a place of safety.
The present European Standard describes the measures to be taken in the design of the vehicles in the
context of the infrastructure on which they operate.
It is not within the scope of EN 45545 to describe measures that ensure the preservation of the vehicles in the
event of a fire beyond what is required to fulfil the objective to protect passengers and staff.
This European Standard is valid for railway vehicles as defined in Clause 3.
Freight transportation vehicles are not covered by EN 45545.

4 Objectives
4.1 General
The objectives of EN 45545 are to minimize the probability of a fire starting, to control the rate and extent of
fire development and through this, to minimize the impact of the products of fire on passengers and staff. The
objectives are considered in the context of the Operation and Design Categories of the railway vehicle.
The different ignition models within the scope of EN 45545 are described in Annex A and form the basis for
the requirements set out in EN 45545, in particular the material and product test requirements set out in
Part 2.
4.2 Fire resulting from accidental ignition or arson
Ignition models, typically involving newspaper, matches, cigarettes and gas lighters are taken into
consideration for any location freely accessible to passengers and staff. These ignition models (Annex A,
ignition model 1 and ignition model 2) have been taken into account in setting out the requirements contained
in this standard, with the objectives of reducing the risk of:
 fire spreading through the passenger and staff areas (see Part 2 relating to material reaction to fire
properties and Part 3 relating to fire barriers);
 endangering passengers and staff by obscuration of escape routes (see Part 2 relating to material
reaction to fire properties in particular smoke emission, Part 3 relating to fire barriers and Part 4 relating to
design principles and evacuation requirements);

 endangering passengers and staff by the presence of toxic fumes (see Part 2 relating to material reaction
to fire properties in particular toxic products of combustion).
NOTE The risk of accidental ignition and in particular arson is considerably lower for areas which are exclusively for
the use of staff. Arson attacks are usually most prevalent in relatively empty vehicles where there is less chance of
intervention.
4.3 Fire resulting from technical defects
Ignition models, comparable to electric arcs or abnormal temperatures are taken into consideration (see Part 2
and Part 5). The effects of any flammable gases or flammable liquids which may be present are also taken
into account (see Part 7). These ignition models (Annex A, ignition model 3 and ignition model 4) have been
taken into account in setting out the requirements contained in this standard, with the objectives of reducing
the risk of:
 fire spreading through the passenger and staff areas (see Part 2, Part 3, Part 5 and Part 7);
 endangering passengers and staff by obscuration of escape routes (see Part 2, Part 3, Part 4 and
Part 6);
 endangering passenger
