of Architecture, Hong Kong University July 1998
(Note: This document is for teaching the students of
Department of Architecture, HKU, and should not be quoted for any other
use. Although aiming at compiling information with accuracy, the writer
declares no responsibility on the accuracy of the information presented.)
1. Introduction
This paper outlines the existing practice administered by
the Authorised person and other fire engineering personnel. It aims to
provide a general guideline for handling the fire safety aspects including
fire services installations of building projects in Hong Kong.
It outlines the commonly used fire safety legislation
documents, the relation between the authorised person and the building
services engineer, the procedures with various authorities and bodies having
jurisdiction, and the role and responsibility of the registered fire services
contractor in these procedures.
2. The Authorised Person and the Building Services Engineer
In the life cycle of a building, namely conception, design,
construction, commissioning and operation, maintenance, modification and
demolition, it is mandatory that an authorised person (AP) be appointed
for submissions of building plans/forms to and negotiations with government
departments/authorities, in accordance with the Laws of Hong Kong, primarily
Chapter 123. An authorised person can either be a registered architect
(AP-List I), or a registered structural engineer (AP-List II), or a registered
building surveyor (AP-List III). An "authorised person" is legally defined
in the Hong Kong Buildings Ordinance Cap. 123. Under the present H.K. Building
legislation system, the AP is to ensure compliance with Building Ordinance
and Regulations, and the building services consulting engineer (BSE) works
as an assistant or a representative of the authorised person in certain
governmental procedures.
Certain BSE are also RPE (Registered Professional Engineers
– Engineers Registration Ordinance, 1990). It is expected to see more direct
responsibility given by the government to RPE in the future. Environmental
Protection Department (EPD) asks for RPE (Mechanical or Building Services)
to sign the emergency generator installation (which is a Fire Service Installation
– FSI) drawings for submission to EPD.
3. The Present Hong Kong Buildings Ordinance/Regulations
Stemming from Buildings Ordinance, Cap 123, the present Hong
Kong Building Regulations are mainly contained in 11 sections of chapter
123 of the Laws of Hong Kong, namely:-
| Hong Kong Regulations, CAP 123 |
Areas of Relevance to BSE |

4. Other Hong Kong Regulations Relating to Fire Services
Other important regulations relating to fire services in
buildings include:-
4.1 Fire Services Ordinance/Regulations
Chapter 95 - Fire Services Ordinance
-
Chapter 95B - Fire Services (Installation and Equipment)
Regulations
-
Chapter 95A - Fire Services (Installation Contractors) Regulations
-
Chapter 95C - Fire Services Department (Reports and Certificates
Regulations)
-
Chapter 95D - Fire Services Department (Welfare Fund) Regulations
-
Chapter 172 - Places of Public Entertainment Ordinance
-
Chapter 295 - Dangerous Goods Ordinance and Regulations
Pursuant to Chapter 95, FSD makes the following issues
to supplement and amplify the F.S. requirements:-
- Codes of Practice on Minimum Fire Services Installations
and Equipment, and Inspection and Testing of Installation and Equipment,
the latest issue was made on March 1994 abbreviated as COP-FSI and COP-I&T.
These codes are issued pursuant to Section 16 (1)(b) (ii) and 21 (6)(d)
of Buildings Ordinance, Cap 123 and Regulation 10 of Fire Service (Installations
and Equipment) Regulations of Fire Services Ordinance, Cap. 95.
- Occasional FSD circular letters issued to the H.K. fire
profession.
- F.S. ventilation circular letters issued to the H.K.
fire profession.
- Sheets relating to the requirements for places of public
entertainment (e.g. restaurants), requirements for installations related
to dangerous goods (the Dangerous Goods Technical Sheets - DG/TS series
sheets) are given by FSD for projects from case to case.
- Standing orders and circulars which are issued internally
within FSD and not disclosed to the public. Many of such issues relate
to building plan approval and F.S. installation requirements.
Particular attention shall be made to Clause 1.3 of the
Codes of Practice stipulating that the Director of Fire Services (i.e.
his delegated representative officer also) may vary any requirement of
the code in particular cases. This gives the F.S.D. the final power to
specify F.S. provisions to buildings.
In addition to the above issues, FSD is also enforcing
the following Rules/Codes/Standards, as referred to in the COP for FSI.
| F.S. Installation |
Code/Rule/Standard |
| Sprinkler system |
Fire Offices' Committee (F.O.C.)
Rules for Automatic Sprinkler Installations (29th edition,
Nov 1973) and LPC (Loss Prevention Council) Rules and Technical Bulletins,
until recent years.
For building plans with first B.O.O. submission made on
and after 1 April 1995, the LPC Sprinklers Rules, comprising BS 5306: Part
2 and LPC Technical Bulletins, as amended by FSD Circular Letter No. 2/94
of 16 Sept 94, will apply.
(Note: FSD accepts deviation from LPC Sprinkler rules
for Improvised Sprinkler Installations, which are installed for enhancing
safety of old commercial buildings, for example) |
| Automatic fire alarm and detection
system |
In Feb. 1985, FOC issued the 12th
edition called "Rules for Automatic Fire Alarm Installations for the Protection
of Property" for property protection, which calls for BS5839 : Part 1:
1980 for life protection.
Currently FSD is discussing the LPC Rules for automatic
fire detection and alarm installations for the protection of property (1991)
which comprises BS 5839: Part 1: 1988 and additional LPC requirements. |
Roller Shutters / Fire Doors
Notes
-
BD/FSD is accepting the standards and test certification
of some reputable testing laboratories of UK, Australia, New Zealand, etc
as listed in the latest issue of FSD Circular Letter on Fire Test Facility.
-
FSD also accepts National Fire Code (NFC) 80 (National Fire
Protection Association – NFPA USA) for fire doors and windows, covering
shutters also.
-
All fire shutters proprietarily made to be submitted separately
to FPB/FSD and BD for acceptance for each project.
|
FOC in Feb 1985 issued revised
rules for fire shutters and fire doors called "Rules for the Construction
Installation of Fire break Doors and Shutters" comprising 4 specifications,
namely, steel plate doors, metal covered doors, steel rolling shutters,
proprietary doors and shutters". These rules are no longer used in HK.
Building Department now specifies fire shutters to comply with the relevant
parts of BS476. |
| External Drenchers |
Separate submission to FSD on individual case basis. |
| Carbon Dioxide System |
NFC12 (NFPA, USA) |
| Halon 1301 system or BTM system
(existing installations only. Import of Halon 1301 to HK is banned) |
NFC12 (NFPA, USA)
(Note: No new Halon 1301 systems to be installed, observing
The Montreal Protocol of 1987) |
| Halon 1211 system or BCF system
(existing installations only. Import of Halon 1211 to HK is banned) |
NFC12 (NFPA, USA)
(Note: No new Halon 1211 systems to be installed, observing
The Montreal Protocol of 1987) |
| Clean agent systems |
NFC 2001 (NFPA, USA) |
| Water spray fixed system for
fire protection |
NFC15 (NFPA, USA) |
While the above are commonly enforced documents, ALTERNATIVELY, FSD
is accepting equipment and installation and testing standards recognised
and certified by the laboratories/organisations listed in FSD Circular
Letters on Fire Test Facility. The use of alternative equipment/standard
has to be stated in the F.S. Notes in drawings submitted to BOO/FSD.
Furthermore, FSD issues a series of Fire Protection Notice and educational
leaflets and pamphlets. Fire Protection Notice No. 4 on Dangerous Goods
General is of particular concern as it lists the requirements for D.G.
licensing, penalty clauses, and exempted quantities for common dangerous
goods.
Also note that some other codes / standards (e.g. Institute of Petroleum
Codes) are referred to in some of the documents mentioned in this section.
4.2 Water Ordinance
Chapter 102 Waterworks Ordinance and Hong Kong Waterworks Standard Requirements:
Sheet No. 1 to 10 are relevant. Sheet No. 4 for installation of storage
cistern (or water tanks) and sheet No. 9 for installation of a fresh/salt
water fire service are applicable to F.S.
Water Supplies Department (WSD) occasionally issues circular letters
to licensed plumbers. Letters of particular concern are:- letters dated
July 2, 1982 and November 12, 1982 on approval of water supply fittings;
and a letter dated August 24, 1984 on Point Penalty System for Defects
in Plumbing Works carried out by licensed plumbers. WSD published "A guide
to the Preparation of Plumbing Proposals" (for submission to Water Authority
for approval) in March 1995. This guide applies to water-based FSI.
4.3 Miscellaneous Regulations and Other Bodies Having Jurisdiction
-
Electricity supply ordinance (Chapter 103 of Laws of Hong Kong) and the
power supply companies - China Light & Power Co. Ltd., Hong Kong Electric
Co. Ltd.
-
The Hong Kong Radiation Board under the Medical and Health Department controlling
ionization smoke detector installation and storage.
-
Port Works (e.g. for fire safety of seaside pump house, requiring fire
extinguishers, fire detectors sometimes)
-
Environmental Protection Department (e.g. for emission of flue gas from
diesel pumps and diesel emergency generators of F.S. Installations)
-
Labour Department - HK Law Cap 59 - Factories and Industrial Undertakings
Ordinance/Regulations (e.g. Fire Safety for industrial plants in operation)
-
Education Department (e.g. for fire fighting equipment for school laboratories)
-
Civil Aviation Authority (e.g. for fire services installation for helipads)
-
Hong Kong Telecom (for direct telephone line connection to Fire Services
Communication Centre, usually applied through the F.S. Contractor and Chubb
carrying out maintenance for the control panel at the FS control centre).
-
Regional Services Department (and Licensing Authority) (e.g. for Hotel
licensing F.S. requirements.) and Urban Services Department (e.g. for licensing
requirements for related business).
-
The Fire Insurance Association of Hong Kong - which is the local channel
to UK LPC adviser to its member insurance companies of F.S. requirements
for buildings.
5. Approval and Certification Procedures Relating to Buildings
The fire services approval and certification procedures require inputs
and participation from the building services engineer to the AP.
5.1 Approval of Architectural Building Plans
The Building Ordinance Office (BOO) of Buildings Department acts as a coordinator
and overall approval office of building plans submitted by the AP.
2 sets out of 6 sets of building plans submitted by the AP to BOO will
be transmitted to the Fire Protection Bureau (FPB) of FSD. For new submissions
FPB/FSD will within 40 days return the comments to BOO. At the same time
FPB/FSD will copy the comments and the marked up drawings to the AP. The
processing of resubmissions by FPB/FSD will take 20 days.
The return of comments from BOO will take 60 days for new submissions.
In addition to FSD comments, these BOO comments will also cover Highway
Office comments, CSD comments, etc. as appropriate. All these comments
must also be thoroughly read for fire safety requirements, and out of these
many comments, usually a few are also related to FS installation.
Approval of building plans usually will take one or more resubmissions.
In preparing the building plans for submission, the AP, in consultation
with the BSE shall prepare a set of F.S. Notes, and shall mark on all architectural
plans the F.S. requirements such as fire shutter, fire extinguisher, pedestal
hydrant, fire hydrant, hosereel, F.S. inlets, sprinkler inlets, foam inlets,
drencher inlets, fire control panel, etc. and shall annotate on all architectural
plans the exact type of protection (i.e. sprinkler, AFA, drencher, foam,
gas protection system, water spray), etc. for each area.
The AP and BSE shall possess a set of the land lease conditions pertaining
to the building site and observe all the fire safety requirements laid
down in this document.
A set of suggested F.S. Notes for a medical related building is enclosed
in Appendix A for reference. The suggested General Notes to be prepared
by the AP are also enclosed in Appendix A for reference. The F.S. Annotation
on the building plans and the F.S. Notes shall be prepared as detailed
as possible to avoid unnecessary clarification, and disputes that may come
up during FSD inspection. The building plans when accepted by FSD are chopped
"Approved" and signed by the FSD officer. These approved architectural
building plans form the basis of development of further fire services installation
design, and design and construction for other fire safety features.
To avoid rejection of submission and to clarify FSD requirements in
case of doubt in interpretation of codes and regulations, prior to building
plan submission, meetings should be arranged by the AP (assisted by BSE)
with FSD to enable the AP, the BSE and sometimes the Client's representative
together, to seek FSD's confirmation on F.S. requirements.
The term "temporary occupation" must be avoided as far as possible,
except that in case where the main switch/transformer room, F.S. tank/pumps
and other main items are really temporary. Otherwise, the term "Phased
Occupation" shall be used if part of the building is to be occupied in
advance. This is because FSD rules that inside T.O.P. areas, no F.S. Installation
modification is allowed.
For buildings installed right on the sea front (such as the seawater
pump houses in Central) the AP and BSE has to provide the same F.S. annotations
and mark up on the plans. However, because the buildings are usually of
a simple nature and small size, simple F.S. Notes are usually sufficient.
Submission to Port Works is also required for these buildings.
5.2 Approval by the Fire Insurer
At the start of the project, the Client's confirmation of the fire insurer's
requirements for the building during construction and after completion
should be sought, because a few insurers may require F.S. protection measures
over the local FSD requirements.
Most fire insurers in Hong Kong are members of The Fire Insurance Association
of Hong Kong (HKFIA) which will advise the landlord via the insurer the
fire services requirements of the building, if requested by the insurer
(insurance company). Compliance of the insurer's F.S. requirements will
usually result in a reduction of premium for the insured building. The
insurer's F.S. requirements are usually slightly different from FSD requirements
though FSD is enforcing LPC Sprinkler Rules, FOC AFA Rules, and LPC Fire
Door/Shutter Rules, which are also used by the insurers.
Note that FOC ceased to operate since June 30, 1985, and a newly created
body called the Loss Prevention Council (LPC, UK) takes over FOC's previous
technical functions. Written enquiries about LPC documents can be sent
to LPC (UK) directly.
The insurer usually requires concept design schematics and architectural
layout in the beginning. Tender F.S. schematic and F.S. layout drawings
developed in accordance with the approved architectural building plans
and the fire insurer's requirements should be sent to the insurer at soon
as they are available. The insurer may as well require the F.S. contractor's
as-fitted drawings before carrying out the acceptance inspections. Furthermore,
the insurer may ask for additional tests, other than those carried out
during FSD inspection.
The insurer is also concerned with the maintenance of the building F.S.
installations and other F.S. features for the whole building life cycle.
Annual/routine inspection and testing requirements should be observed by
the F.S. maintenance contractor and the building management, also in compliance
with the insurers' requirements.
5.3 Approval and Certification by FSD
The internal divisions of FSD to be approached by the AP and BSE are listed
below:-
| Divisions |
Items Concerned |
| 5.3.1 Planning Group of Headquarters of FSD
at FS HQ Building, No. 1 Hong Chong Rd, Tsimshatsui, Kowloon |
Pedestal hydrant (outside building lot boundary)
and fire engine access - submission and meeting to be arranged by the AP,
assisted by BSE |
| 5.3.2 New Projects Division of FPB at FSHQ
Building |
Pedestal hydrant pipework layout, if required,
to be submitted by the BSE. |
| 5.3.3 Fire Services Installation (FSI) Division
on FPB at FS HQ Building
|
Building Plan Approval Submission (via BOO)
and meetings to be arranged by the AP, assisted by the BSE.
F.S.I. details and drawings - submission and meeting on
FSI details to be arranged by the BSE to clarify items not clearly defined
by the F.S. Notes and the Codes/Rules and Regulations, and circular letters
etc. Because FSI drawings endorsed by FSD, submitted along with Form FSI/314,
do not mean acceptance of FSI design/layout by FSD, the BSE must obtain
separately in writing, on FSD's acceptance of the proposals in case the
installation details are not clearly covered by relevant Rules & Regulations.
Sketches and descriptions in detail are required for such
separate submissions. e.g.
-
Pedestal hydrant system
-
Stage proscenium drencher systems
-
Unusual F.S. designs
-
Unusual Sprinkler System
Usually FSD accepts advices given in writing by HKFIA/LPC.
Note:
Form FSI/314 for submission of FSI layout drawings shall
be signed/submitted by the registered F.S. Contractor and the AP. The FSI
drawings returned are not FSD approved drawings. FSD only chop the
drawings as a matter of procedure.
FSI inspection & Certification-Submission of Form
FSI/501 to FSD for request for FSI inspection to be coordinated by the
AP/BSE. Form 501 to be signed by Registered F.S. Contractor and the AP.
Upon satisfactory inspection, this division will issue
F.S. Certificate FS172 which is a pre-requisite for issuance of the Occupation
Permit by BOO.
Inspection is now carried out by building services inspectors,
headed by an engineer of EMSD seconded to FSD. Previously inspections were
carried out by FSD uniform officers.
The Registered F.S. Contractor has to inspect/test all
F.S.I. annually and issue a certificate to the protected property owner,
copied to this Division annually, confirming the inspected/tested FSI are
in proper function. |
| 5.3.4 Investigation and Research Division of FPB/FSD
at FSHQ Building |
This division deals with fire investigation and approval
of FS equipment submitted by the equipment dealer/suppliers such as detectors,
sprinklers, fire shutters, hosereels, fire extinguishers etc.
In approving the Contractor's submission of equipment,
the AP/BSE shall study the FSD approval letter of the equipment and other
documents referred to in this approval letter for clarification of the
scope of approval. |
| 5.3.5 Ventilation Division of FPB/FSD at FSHQ Building |
Ventilation Division administers The Building (Ventilation
Systems) Regulations Subject to FSD Circular Letter No. 1 (Vent)/90. This
division now does not normally examine the fire safety aspects of HVAC
drawings and design and inspect the HVAC installations, covering fire dampers,
ductwork insulation material etc. Self regulatory certification by the
registered ventilation contractors is enforced. The submission and contact
to this division should be coordinated by the BSE (HVAC engineers)
Remark:
Smoke control systems including ventilation/air conditioning
system, staircase pressurization system (SPS) and smoke extraction system
(SES) are fire service installations in accordance with COP-FSI and are
under the control of FSI Division.
At present, an engineer in FSI Division will carry out
conceptual checking of design drawings for SPS and SES during the planning
stage so as to avoid any irrecoverable error discovered at the time of
FSI inspection upon building completion.
Although the inspection of HVAC system [as governed by
the Building (Ventilation Systems) Regulations] by the Ventilation Division
is not a pre-requisite of issuance of the Occupation Permit, satisfactory
completion of these related F.S. requirements occupation will ensure integrated
fire safety for the building. |
| 5.3.6 Regional Offices of FPB |
At present, there are 3 regional offices, located at:-
Sheung Wan Fire Station for activities of Hong
Kong Island and outlying islands, and marine activities.
Fire Services Headquarters Building for Kowloon
Peninsula activities.
Shatin Fire Station for New Territories activities
(also with a sub-office at Tsuen Wan Government Offices Building)
The regional offices are responsible for approval, inspection, licensing
for fire protection requirements (both architectural and F.S.I. requirements)
for installations and premises involving dangerous goods and for Places
of Public Entertainment. All E/M installations covering piped liquid/fuel
installation, compressed air piped installation, diesel fuel equipment
and pipework installation, boiler/incinerator installation, etc. shall
be submitted by the BSE to the appropriate offices for approval. The FSD
requirements always cover architectural requirements. Thereforethese
requirements must be observed both by the AP and BSE.
Regarding dangerous goods, it is desirable that the AP
should submit the details of the quantities and the types to the Regional
Office for approval as the F.S. requirements are usually more difficult
to comply with on the architectural aspects than F.S.I. aspects.
The BSE must also ensure the FSD officers from the Regional
Office will inspect satisfactorily the related premises and installation
prior to engineers/engineering inspectors from the FSI Division/FPB carry
out testing and inspection of the building as a whole. Satisfactory Inspection
Certificate/Letter from the Regional Offices to FSI Division is a pre-requisite
for issuance of F.S. Certificate FS172, which is in turn a pre-requisite
for O.P. Issuance by BD. (See Section 5.3.4) |
Note: For the construction site
hydrant/hosereel system, it is not necessary to submit it or request inspection
of it from any division of FSD stated above as this system will be inspected
by FSD officers of the fire stations nearest to the construction site.
|
5.4 Gas Safety Office of EMSD
Bulk storage and transportation, transmission, manufacture
and use of gaseous fuel are to be submitted to this office for approval.
5.5 Urban Council - district offices
The licence holder must seek the fire safety requirements
for licences of cinemas, restaurants, commercial kitchens, from these offices.
5.6 City and New Territories Authority - Office of the Licensing
Authority
The licence holder must seek the fire safety requirements for hotels, hostels,
and private clubs, from this office.
5.7 Environmental Protection Department
The exhaust pipe arrangement for emergency diesel generators, which is
a F.S.I., and diesel fire service/sprinkler pumps are to be submitted to
EPD for approval.
5.8 Approval and Certification by Water Authority
At the start of the project, written confirmation must be obtained from
Water Supplies Department regarding the pressure, size of water main, water
main arrangement (double-end feed or single end feed) and location of F.S.
supply connection to the city main, and in some cases the location of Government
pedestal hydrants and their main supply details and salt water main details.
F.S. schematics and water connection arrangement, including
the details for the pedestal hydrant system in some cases shall be submitted
by the BSE or AP to Water Authority (on H.K. Island - H.K. Sub-Office at
North Point; on Kowloon and N.T. - to the Kowloon Sub-Office at Sai Yee
Street, Mongkok) for approval as soon as available. Only after their approval
by Water Authority, the procedures covered by the following forms related
to F.S. can be carried out.

examinations, but recognises relevant Technical Institute Cert. holders
for licensed plumber registration.
-
For subsequent changes of FSI after occupation Permit is issued:-
-
involving no change in tank size and pipework upstream of incoming tank,
no need to inform WA, but to inform FSD using form FS 251.
-
involving change in tank size and pipework upstream of incoming tank, to
inform WA & FSD.
-
consult WA in case of doubt
-
WA is enforcing self regulation - point penalty scheme
|
5.9 Approval by the Power Company
The gas flooding system layout for the transformer room (housing oil-filled
transformers) must be sent to the power companies for approval before tendering.
The comments from the power companies must be complied with. They will
send inspectors to inspect the transformer room/HV switch room including
the F.S. installation before they will accept the room for installing transformer/switchgear.
The power companies usually request as-fitted drawings for the transformer/HV
switch rooms to be submitted to them for record purpose after the FSD inspection
is satisfactory. The BSE shall obtain from the F.S. Contractor these drawings
and submit them to the power companies.
Both the building owner and power company possess the keys of the transformer
room, but no access to the room shall be allowed without prior consent
of the power company except in case of emergency.
5.10 Procedures and Submission to be Carried Out by the Registered
F.S.I. Contractor
5.10.1 FSD Procedures & Submissions
It is mandatory that all F.S.I. works must be carried out by registered
F.S.I. contractors, who are registered with HKFSD. The registered F.S.I.
Contractors are listed into 3 classes, namely, class 1 for AFA system,
Class 2 for wet fire fighting system and other FSI using pipework to distribute
the fire fighting medium and F.S.I. not taken care by class 1 and class
3 contractors; and Class 3 for portable fire extinguishers. Class 3 is
personal registration, and Class 1 and Class 2 are company registration.
The registered F.S.I. Contractor of the relevant class must be employed
to carry out the F.S. installations as appropriate.
The Contractor shall prepare Form FSI/314 and 2 complete sets of F.S.I.
drawings coloured for submission to the AP for endorsement and subsequent
submission to FPB/FSD (see Section 5.3.3). Prior to submission, the BSE
shall cross check the F.S.I. layout in order to ensure that the F.S.I.
layout agrees in every respective to the following items:-
-
the latest set of architectural drawings kept at FSD and approved by FSD,
for architectural layout and F.S.I. provisions.
-
the rules and regulations enforced by all authorities.
-
the relevant content of written confirmation/correspondence between the
AP/BSE/F.S. Contractor and HKFIA/FSD/WA and other bodies having jurisdiction.
It is reasonable to allow one month for processing of the FSI drawings
and Form FSI/314 by FSD.
Form FSI/501 requesting for FSD inspection on the F.S. installation shall
be prepared by the Contractor and submitted to the AP for endorsement for
subsequent submission to FPB/FSD. From experience, One month should be
allowed in between the submission of Form FSI/501 and the arrival of FSD
engineering inspectors (from FSI Division, FPB) at site for carrying out
inspection.
Because the contractor is responsible for ensuring that all the equipment
is approved by FSD, he shall coordinate for the equipment submission (such
as fire shutters) to the FPB/FSD as appropriate. (see Section 5.3.4)
5.10.2 WA Procedure & Submissions
The contractor shall submit the related forms to Water Authority. (See
Section 5.8)
5.10.3 Submission to Hong Kong Radiation Board
The contractor shall submit relevant details, drawings, catalogue and form
(which has to be signed by the landlord also) to the H.K. Radiation Board
(See Section 4.3) regarding the radioactive ionization smoke detectors
and obtain the required licence for the landlord as appropriate.
The radiation board monitors, tracks record of ionization material (e.g.
Am 241) of the smoke detectors by:-
-
If the ionization level exceeds the exempted amount, separate licences
are required, for transportation, storage, FSI in buildings.
-
Annually, Radiation Board asks FSI contractor to report on amount of ionization
content stored, removed, disposed, for annual licence renewal with annual
fee charged.
-
For changes of quantity of ionization of smoke detectors in buildings,
the owner has to inform radiation board directly or via the FSI contractor.
-
5.10.4 Submission To Chubb (H.K.) Ltd
The Contractor shall submit to Chubb (H.K.) Ltd. for the direct connection
from the fire control panel of the building to the Fire Services Communication
Centre (FSCC) as Chubb is the installer and house-keeping company for the
electronic panel of FSCC. Chubb will subsequently arrange with Hong Kong
Telephone Co. Ltd. for providing the direct telephone line. The Contractor
shall ensure that the direct connection is completed before FSD inspection
engineers/engineering inspectors from FSI Division of FPB/FSD carry out
site test and inspection. Otherwise the landlord has to provide a normal
workable telephone (for proper external dialling) and 24 hour human attendance
at the fire control panel.
Chubb Electronics Ltd installed and offers house keeping services of
the multiplex automatic fire alarm connection system from buildings to
FSD. Signals from buildings A, B, C, etc. are connected to a few fire stations,
in which are installed concentrators to concentrate and transmit the signals
to Chubb centre, and FSD control centre in FSHQ Building in Tsimshatsui
East in a parallel manner by a ring circuit.
5.11 F.S. Procedures and Submissions for Building Maintenance/Modification/Demolition
For maintenance/modification/demolition work on F.S. installations, i.e.
FSI suspension, the F.S. contractor shall inform the FSCC immediately.
The FSC depending on situation, will not despatch FSD engines if alarms
are transmitted to the centre via the direct telephone line during this
F.S.I. suspension period.
Depending on the nature of the work the Contractor shall inform the
Water Authority (see Section 5.8), the FPB/FSD (see Section 5.3), the Hong
Kong Radiation Board (see Section 5.10.3) as appropriate.
6. Proposed Legislation for Designing, Installing and Maintaining
Fire Services Installations and Mechanical Ventilation Systems
A few years ago, EMSD circulated to the professional bodies for comment
a revised FS ordinance (Note: The key points are shown in the enclosed
Appendix B1) for registering separate groups of registered persons and
contractors for carrying out the design and installation/testing/maintaining
of fire services installations, aiming at setting up a self-regulatory
system of designing and installing/testing/maintaining Fire Services Installations.
The present role and responsibility of EMSD engineers/inspectors in inspecting/witnessing
the F.S. installations/tests would then be transferred to a group of registered
persons. EMSD would conduct proper monitoring to insure the satisfactory
operation of the self-regulatory system.
A similar draft ordinance for mechanical ventilation system (Note: The
key points are summarised in the enclosed Appendix B2) was also
circulated by EMSD to replace the existing Building (Ventilation Systems)
Regulations. (see Section 3)
Discipline, penalty, and appeal clauses are also included in the proposed
legislation.
7. Conclusion
Regulations and codes etc. relating to building fire safety are numerous
and continuously changing. In addition, fire service procedures and submissions
are tedious and complicated. These are frequently changing too. FSD issues
Circular Letters from time to time to announce the changes, and their enforcement
time. The authorised person and the building services engineer, together
with the registered FSI contractors, have to develop unbeaten patience
and endeavour in coping with the changes and going through all these procedures
and submissions, and inspections.

APPENDIX B
The Proposed Legislation for Fire Services Installations and Mechacnical
Ventilation System
(B1) The proposed F.S.I. legislation
The proposed F.S.I. legislation will cover fire service (installations),
and fire service (registration).
The duties of the registered engineer (fire service) [RE(FS)]
will include design, supervision, inspection, witnessing of commissioning
tests, and certification of fire services installations. There will be
two grades of RE(FS), namely, Grade A - for conventional FSI, and Grade
B - for smoke control and management systems. The general qualification
for RE(FS) will be registered professional engineer (RPE) of Hong Kong
of the appropriate discipline plus 3 years relevant experience.
The duties of registered contractor (fire service) [RC(FS)]
will include:-
(i) for new F.S. installation - installing, inspecting,
setting to work, testing and commission, and certification, and
(ii) for existing installation - altering, inspecting,
repairing and maintaining, annual statutory inspection, and certification.
The general qualification for RC(FS) will include a registered
professional engineer of Hong Kong with 3 years experience in relevant
field, adequate office and workshop, and adequate human resource to carry
out work.
There will be three grades of RC(FS):-
(i) Grade A - For inspecting, certifying, repairing
and maintaining F.S.I. other than those carried out by Grades B and C (i.e.
Grade A will take care conventional FSI systems)
(ii) Grade B - For inspecting, certifying, repairing
and maintaining smoke management systems
(iii) Grade C - For inspecting, installing, certifying,
repairing and maintaining portable equipment
The proposed fire service (installations) regulations will
state that:-
(i) No person shall design, supervise, inspect, witness
commissioning test, certify new or amend installation unless he is a RE(FS)
of appropriate grade, and
(ii) No person shall install, alter, extend, test, commission,
repair, maintain or certify FSI unless he is a RC(FS) of appropriate grade
The duties of the owners will include employing RE(FS) of
appropriate grade to design and certify the new and/or alter fire service
installations; and employing RC(FS) of appropriate grade to install the
new and/or alter fire service installations; and employing RC(FS) of appropriate
grade to carry out annual statutory inspection on existing fire service
installations and to ensure his FSI in efficient working order at all times;
and displaying a valid maintenance certificate at a prominent position.
The proposed building plan/drawing submission will be
identical to the existing procedures, namely, AP to submit plan to BOO,
then BOO to refer plan to FSD, then FSD to check plan against COP, formulates
FSI requirements and endorse plans/drawings.
The proposed FSI plan/drawing submission will be:-
(i) RE(FS) to prepare FSI plans/drawings based on approved
building plan/drawings
(ii) RE(FS) to submit FSI plans/drawings to DEMS (i.e.
Director of electrical and Mechanical Services)
(iii) DEMS to endorse FSI drawings/plans and return one
set to RE(FS)
Note: FSI plans/drawings will be randomly selected
for detailed checking and a point system will be introduced to monitor
the performance of RE(FS)
The proposed legislation procedures for installation and
certification of FSI will be:-
(i) RC(FS) to install FSI in accordance with FSI plans/drawings
endorsed by DEMS
(ii) RE(FS) to supervise installation and testing of
FSI
(iii) RE(FS) and RC(FS) to certify installation on completion
(iv) RE(FS) and RC(FS) to forward the certificate to
DEMS for endorsement
Note: DEMS will randomly check the certificates and
select F.S. installations for inspection and checking. A point system will
be introduced to monitor the performance of RC(FS).
For the proposed annual statutory certificate, the RC(FS)
shall carry out annual inspection in full compliance with the fire services
ordinance, and shall issue the certificate to the owner and forward a copy
to DEMS.
(B2) The proposed legislation for mechanical ventilating
system
To substitute the existing Building (Ventilating System)
Regulations under building ordinance - Chapter 123 HK Law, the proposed
legislation will be on fire safety and health aspects covering fire dampers,
cleaning of filters etc. The proposed documents will include mechanical
ventilating system ordinance, and mechanical ventilating system regulations,
and mechanical ventilating system (registration) regulations.
The exemption from the proposed ordinance will include
FSI smoke control system, and individual units less than 15kW without ductwork.
The proposed certification exemption will include ventilating system less
than 2000 L/S.
There will be one grade in the proposed registered engineer
(ventilation) [RE(V)] ordinance and regulations, who will generally be
registered professional engineer of Hong Kong of relevant discipline plus
3 years of relevant experience.
There will be 3 grades of registered contractors (ventilation)
[RC(V)], namely, Grade A for installing and maintaining systems, Grade
B for maintaining systems, and Grade C for maintaining existing installations.
Existing ventilation contractors will be directly transferred to this new
Grade C.
The qualifications for these 3 grades or RC(V) will generally
be:-
(i) Grade A - RPE of relevant discipline
(ii) Grade B - Higher Cert.
(iii) Grade C - existing ventilation contractors
Relevant and sufficient experience will be required for Grade
A, B RC(V)s.
