Guidelines (Revised 10.1.2013)
Guidelines on Formulation of
Fire Safety Requirements
for New Railway Infrastructures
January 2013
2013
PREAMBLE
The development of railway fire safety design in Hong Kong evolved
from the first underground railway project in around 1970s.
Without preceding project references and prescriptive requirements
under the Codes of Practice for Minimum Fire Service Installations
and Equipment and Inspection, Testing and Maintenance of
Installations and Equipment (FSI Code), the Fire Services
Department (FSD) in collaboration with railway corporations and
other government departments, since then started to draw up fire
safety requirements for railway infrastructures.
Owing to the unique and complex design nature of railway stations
and their associated premises, performance-based fire safety designs
have been widely adopted in the planning of railway projects.
In
principle, fire safety standards provided by the fire engineering
approach should not be inferior to the prescriptive requirements
stipulated in relevant codes and standards.
On top of fire
engineering approach, sets of fire safety requirements drawing on
local practice and experience with due reference to the international
standards on railway safety, such as National Fire Protection
Association 130 (NFPA 130) of the USA and Office of Rail
Regulation (ORR) of the UK, have also been developed.
In gist, the
underlying fire safety design principles for railway infrastructures are
to provide the best fire safety protection to passengers and
operational staff as well as emergency personnel in the event of a fire
and other calamity.
To facilitate stakeholders of the railway industry to adopt a consistent
fire safety design towards new railway infrastructures in the future,
this Guidelines serve to provide general guidance on formulating fire
safety requirements by incorporating the latest fire safety measures of
i
various railway lines under construction in Hong Kong.
Railway
corporations and fire engineering consultants will find this
Guidelines useful in formulating fire safety requirements for new
railway infrastructures in the future, including railway stations,
depots, ancillary buildings and trackside areas.
This Guidelines should be read in conjunction with the current FSI
Code (April 2012 Edition), FSD Circular Letters and the Code of
Practice for Fire Safety in Buildings 2011 (FS Code) issued by the
Buildings Department (BD).
In case of special factors and
circumstances, the Director of Fire Services may require additional
fire safety requirements to be imposed before he is so satisfied.
Moreover, the general fire safety measures relating to Means of
Access (MoA), Means of Escape (MoE) and Fire Resisting
Construction (FRC) stipulated in this Guidelines should be subject to
the final satisfaction and agreement of BD.
Yet, compliance with
the fire safety requirements stipulated in this Guidelines should not
be taken as compliance with the fire safety requirements under the
Buildings Ordinance, which are under the jurisdiction of the BD.
With regard to the fire safety issues to be addressed by the fire
engineering approach, such as determination of fire size, assessment
of tenability, design of smoke control system, evaluation of occupants
evacuation time and pattern, etc., reference should be made to Part G
of the FS Code and other well-recognized international standards and
guidelines, including but not limited to CIBSE Guide E, SFPE
Handbook, etc. The existing mechanism using Computational Fluid
Dynamics (CFD) fire modeling, computational simulation of tunnel
ventilation system, engineering calculation, fire risk assessment, etc.
may also be accepted by FSD on a case-by-case basis.
In fact, a
practical and pragmatic approach would be adopted on a case-by-case
basis when there are any physical constraints leading to
non-fulfillment of the requirements stipulated in this Guidelines and
the railway corporation has made its due efforts in meeting the
ii
requirements.
To meet the higher expectation on railway safety from the general
public and align with the world’s enhanced fire safety requirements,
FSD will keep on reviewing the current fire safety measures and
make amendments if necessary.

Processing Mechanism of Railway Projects
Having regard to the exceptional nature of railway projects, the
Building Authority may, under the provisions of section 54(2) of the
Mass Transit Railway Ordinance (Cap. 556), issue an Instrument of
Exemption (IoE) to exempt such building works from the Buildings
Ordinance (Cap. 123).
Such exemption is confined to those
procedures and requirements relating to the appointment of
Authorized Person and Registered Structural Engineer as appropriate,
approval of plans, consent to commencement and resumption of
works and occupation of buildings under sections 4, 14 to 17A and 19
to 21 of the Buildings Ordinance, such that the Building Authority’s
duties and sanctioning power to ensure standards of health and safety
are not undermined.
Instead of submitting building plans through
the Centralised Processing System for ordinary building projects, the
following Committees with specific “Terms of Reference” are formed
to ensure that railway infrastructures are designed, built and operated
to the required safety standards.
1.4.1
Station and Transport Integration Committee (STIC)
(a) STIC is chaired by the Railway Development Office, Highways
Department (HyD).
STIC members comprise representatives
from Fire Services Department (FSD), Buildings Department
(BD), Transport Department (TD), Hong Kong Police Force
(HKPF), Planning Department (PlanD), Lands Department
(LandsD), Civil Engineering and Development Department
(CEDD), Regional Office of HyD and the railway corporation.
(b) STIC provides a forum for the discussion and agreement, mainly
on the integration into the built environment, construction of
new railway stations, ancillary buildings, depots, or modification
10
to the existing facilities; provision of pedestrian accesses to
station entrances; and integration of other transport modes with
railway services.
1.4.2
Safety and Security Coordinating Committee (SSCC)
(a) SSCC is chaired by the Railways Branch of Electrical and
Mechanical Services Department (EMSD).
SSCC members
comprise representatives from FSD, BD, HyD, HKPF and the
railway corporation.
(b) SSCC provides a forum for the discussion and agreement on the
safety and security related issues of railway stations, depots
and/or other associated structures for which an IoE has been
issued by the Building Authority, including existing and new
facilities, permanent and temporary structures and modification
to the existing facilities.
1.4.3
Trackside Safety and Security Committee (TSSC)
(a) TSSC is also chaired by the Railways Branch of EMSD.
TSSC
members comprise representatives from FSD, BD, HyD, HKPF
and the railway corporation.
(b) TSSC provides a forum for the discussion and agreement on the
safety and security related issues of railway tracksides and
associated facilities for which an IoE has been issued by the
Building Authority, including existing and new facilities,
permanent and temporary structures and modification to the
existing facilities.

1.5
Formulation of Fire Safety Requirements
1.5.1
As one of the core members of STIC, SSCC and TSSC, FSD is
responsible for giving advice on fire safety requirements to railway
projects.
The fire safety requirements stipulated in Part II of the
Guidelines are formulated by making due reference to previous
standards
of
railway
engineering studies,
projects,
international
prescriptive codes,
etc.
standards,
fire
For railway
premises/structures of special designs or hazards which necessitate
special considerations, FSD may accept, on a case-by-case basis, fire
engineering approach as an alternative provided that safety standards
provided by the fire engineering approach should not be inferior to
the prescriptive requirements.
Methodology for application of the
fire engineering approach should outline a structured fire
engineering principle(s) to the assessment of total fire safety
effectiveness and to the achievement of pre-identified design
objective(s) having taken into consideration of the objectives of fire
safety requirements for the protection of life including operation
staff and emergency personnel and property within the railway
premises/structures in the event of emergency.
1.5.2
In
general,
prescriptive
requirements
(Deemed-to-Comply
provisions) of the following local codes or circular letters shall also
be adhered to:
(i) Codes of Practice for Minimum Fire Service Installations and
Equipment and Inspection, Testing and Maintenance of
Installations and Equipment April 2012 (FSI Code) which
stipulate the minimum fire service installations and equipment to
be provided and give guidance as to the conduct of inspections
and tests in order to satisfy the Director of Fire Services; and
12
(ii) FSD Circular Letters which are published from time to time by
the Director of Fire Services requiring Authorized Persons and
other concerned parties to comply with the latest requirement on
fire safety provisions.
(iii) Code of Practice for Fire Safety in Buildings 2011 (FS Code)
which stipulates the requirements for fire resisting construction,
means of escape, means of access and emergency vehicular
access.
In addition, it also provides guidelines on the testing
standards for the fire properties of building elements and
components, fire safety management of buildings and the
alternative approach in fire safety design, i.e. fire engineering
approach.
Insofar as the Buildings Ordinance is concerned, the
FS Code shall apply to railway works that are submitted through
SSCC, TSSC and STIC and the works of which have not yet
been commenced on or before 1 April 2012.

Means of Escape (MoE)
(i) There shall be adequate means of escape for all calculated
population under the worst scenario, as agreed in STIC and
SSCC Stage 1 Submissions, to escape safely from the fire scene
to an adjacent Place of Safe Passage within 4.5 minutes without
being overwhelmed by the effects of fire and smoke.
Inside the
passage, a smoke clear height of not less than 2.5 m is
maintained by the smoke extraction system for a minimum
period of 60 minutes for evacuation.
This will normally be on
the floor immediately above or below or an area adjacent to
where a fire occurred.
Place of Safe Passage shall be provided
with stairway and/or escalator to the next level or Ultimate Place
of Safety.

Safety, leading to the Place of Safe Passage at another level or
the Ultimate Place of Safety, shall not be more than 50 m (25 m
for dead end situation) measured in actual walking distance.
This principle is not applied by just reaching an adjacent smoke
zone maintained as a Place of Safe Passage.
In case there are
site constraints rendering it impossible to fully comply with the
above requirements, an alternative approach will be adopted on a
case-by-case basis, such as the case of long adit scenario.

station), shall comply with the prescriptive requirements of the
FS Code.
(v) A long adit, apart from forming part of the Place of Safe Passage,
also serves as an escape route from the station.
It may connect
various areas of the station via a series of smoke zones, e.g.
platform and concourse or concourse and entrance.
The long
adit shall be constructed of low combustible materials and

Appendix I
Cabin Concept for Concession Area in Station
1.
Background
1.1 “Cabin Concept” has been adopted for the fire safety design
in a number of developments, such as Osaka Bay
International Airport in Japan, Stansted International Airport
in London, Hong Kong International Airport and railway
stations in Hong Kong.
The basic principle of “Cabin
Concept” is to provide protection to high fire load areas
while allowing flexibility in the use of large space without
physical compartment walls.
1.2 Shops or concession areas are generally provided at station
concourses of new railway stations for the convenience of
commuters. Open type cabin concept is commonly applied
to concession areas because these areas are identified as
areas of higher fire load and fire risk as compared to general
station circulation areas.
2.
Design Parameters
2.1 Open type cabin concept relies on a combination of fire
detection, sprinkler and smoke extraction systems.
sketch of the cabin concept is provided in Figure 2.
A
For
concession areas design using the cabin concept, the
provisions are:
(i) fire detection and alarm systems;
(ii) sprinkler system with fast response type sprinkler heads;
(iii) sprinkler apron between the station areas and the shop areas to
protect shopfronts;
(iv) fire rated smoke bulkhead to contain smoke above the apron of
concession areas is to be fixed at 15o from shop demise (shutter)
line;
(v) dedicated smoke extraction system which is independent of the
smoke extraction system for the station public areas; and
(vi) portable hand-operated approved appliances.
2.2 A fire within a cabin shall be detected at an early stage by a
smoke detector at ceiling level.
This shall automatically
switch on the smoke extraction system.
The cabin shall be
fitted with smoke barriers at its boundaries to create a
reservoir to prevent the smoke from spreading outside the
cabin.
Under the protection of the sprinkler system, the
fire occurred inside the cabin shall be limited to a design
fire size of not exceeding 2 MW.
2.3 In general, the maximum area of a single cabin shall not
exceed 100 m2.
A dedicated smoke extraction system,
which is independent of the smoke extraction system for the
station public areas, shall be provided for the open cabin.
The protected area may be a single concession area or a
group of concession areas served by a common smoke
reservoir.
One smoke reservoir will serve a maximum area
of 100 m2 cabin zone.
However, one smoke extraction
system may serve several cabin zones without exceeding a
total smoke zone area of 2 000 m2.
2.4 The separation walls between different cabin zones and
other back-of-house areas will be in full height with an FRR
of not less than 1 hour and 2 hours respectively.
Non-full
height separation wall of not lower than the designed smoke
clear height with an FRR of not less than 1 hour is allowed
for separating different concession areas within the same
cabin zone while sharing the same smoke reservoir. The
enclosure wall, if any, separating the concession area and
station public area, will have an FRR of not less than 2
hours.
The shopfront will not have any fire rated
separation provision under open cabin design.
However, a
passage having a minimum width of 6 m in the front of the
concession area measuring from the shop demise line should
be maintained.
2.5 Apart from the above provisions, only trades approved by
SSCC shall be permitted in the concession areas.
All
trading activities shall be contained within the protected
concession area (cabin) and no combustibles are allowed to
be placed or protruded out of the designated shopfront area.
2.6 Practical smoke tests shall be carried out in the cabin to the
satisfaction of FSD.
2.7 The previously agreed trade list is enclosed in Appendix V
for reference.
Future trade list should be agreed on a
case-by-case basis.
