This Code of Practice shall be titled “Minimum Fire Service Installations and Equipment”
hereinafter referred to as “The Code”.
1.2 Definitions
“Building” means
As defined in Buildings Ordinance Cap. 123.
“Cubical Extent” means
The space contained within the external surfaces of the walls and roof of a building and the
upper surface of the floor of its lowest storey, excluding any space within any enclosure on the
roof used exclusively for accommodating a water tank or lift gear or any other services, and, if
any side of the building is not enclosed by a wall, that side shall be deemed to be enclosed by a
wall extending downwards from the outer edge of the roof.
“Fire Compartment” means
An enclosed space in a building that is separated from all other parts of the building by enclosing
construction providing a fire separation that may be required to have a fire-resisting rating.
“Fire Load” means
The theoretical amount of heat that may be released during the burning of combustibles in the
building under fire conditions and is computed by the formula:
Calorific value of contents in MJ/kg × weight of contents in kg
Floor area in square metres
“Fire Service Installations or Equipment” means
Any installation or equipment manufactured, used or designed to be used for the purpose of:
(a) extinguishing, attacking, preventing or limiting a fire;
(b) giving warning of a fire;
(c) providing access to any premises or place for the purpose of extinguishing, attacking,
preventing or limiting a fire;
(d) facilitating the evacuation from any premises in case of fire;
(e) providing a stand-by power supply to an installation or equipment the purposes of which are
mentioned in paragraphs (a) to (d) in the event of the loss of normal power supply.
“Natural Venting of Staircases” means
As an alternative to pressurisation of staircase by provision of venting of smoke from staircase in
accordance with Section 2 of BS 5588: Part 5: 1991 in particular paras. 8.4(a), (b) and (h) and the
latest version of the Standard.
“Place” means
Any area, lot or site on which buildings are located.
“Premises” means

1.3 Discretionary powers of the Director of Fire Services
Compliance with the prescriptive provisions in this Code may be regarded as a reliable way to satisfy the
requirements for fire service installations or equipment. However, the Director of Fire Services may, in the
case of any particular building, vary any of the requirements of the Code (whether by requiring the
provision of any fire service installations or equipment not indicated in the Code either in addition to or in
substitution for any fire service installations or equipment so indicated or by relaxing any of the
requirements in the Code or otherwise) where, in his opinion, such a variation is required in order to ensure
the provision of all such fire service installations and equipment, as, having regard to the purpose for which
the building is intended to be put, comprise the minimum fire service installations and equipment necessary
for that building/premises, or as the case may be, where such a variation is not inconsistent with the
provision for the building of all such fire service installations and equipment as aforesaid.
For buildings of special designs or hazards which necessitate special considerations, the Director of Fire
Services may accept, on a case by case basis, fire engineering approach as an alternative to the prescriptive
provisions provided that the fire engineering approach should not provide inferior safety standard 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 building fire safety effectiveness and to
the achievement of pre-identified design objective(s) having taken into consideration of the objectives of
fire service installations and equipment for the protection of life and property of the people within the
premises and the firefighting personnel in the event of emergency.
1.4 Approval of plans for building works
The Building Authority may, under Section 16(1)(b) of the Buildings Ordinance, refuse to give his
approval of any plans of building works where:
“the plans are not endorsed with or accompanied by a certificate from the Director of Fire Services
certifying either:
(i) that, having regard to the purpose to which the building is intended to be put (which purpose shall be
stated in the certificate), no fire service installation or equipment is necessary in connection with the
building that will result from the carrying out of the building works shown on the plans; or
(ii) that the plans have been examined and are approved by him as showing all such fire service
installations and equipment as in his opinion, having regard to the purpose to which the building is
intended to be put (which purpose shall be stated in the certificate), comprise the minimum fire service
installations and equipment necessary for the building in accordance with the Code of Practice
published from time to time by the Director of Fire Services”.
1.5 Provisions of emergency vehicular access and street fire hydrants
When designing their projects, the Authorized Persons should take into account the provisions of
emergency vehicular access and street fire hydrants for the development in addition to the fire service
installations and equipment in the building(s).
1.6 Design of fireman’s lift and firefighting and rescue stairway
Whilst the requirements for fireman’s lift and firefighting and rescue stairway are included in this
Code, it should be pointed out that these are formulated in accordance with Reg. 41B and 41C of the
Building (Planning) (Amendment) Regulations 1995 and as such are not considered as fire service
installations within the meaning of para 1.2 above.
1.7 Standards
The standards, specifications, rules, statutory requirements, etc. quoted in this Code shall be the
current version at the time of building plans submission for approval.
For any non-standard provision of Fire Service Installations or Equipment, the standards and
specifications shall conform to the prescribed requirements as specified by the Director of Fire Services.

Notes on Portable Equipment Maintenance Label
(Including fire extinguisher, fire blanket, sand bucket and fixed type extinguisher)
1.
Company Name
Either the name of the company or the company chop should be printed on the space provided.
If company name is not applicable, “NA” should be entered and should not be left blank.
2.
Registration No.
The registration number of the Class 3 Fire Service Installation Contractor responsible for the
maintenance of the portable equipment should be filled in.
3.
F.S. 251 No.
The number of the relevant Certificate of Fire Service Installation and Equipment (F.S. 251)
should be filled in.
4.
Maintenance Date
This date means the date when the maintenance of the portable equipment is completed. It
should be the same date as shown on the Certificate (F.S. 251).
5.
Next Maintenance
This date means 12 months later and should be counted from the date of the last maintenance.
If within 12 months period, the fire extinguisher is required to have pressure test, then the
date of pressure test should be filled in.
Example :
Maintenance Date
: 5.9.2003
Last Pressure Test
: 10.7.1999 (pressure test is required for
every 5 years intervals)
Next Maintenance
6.
: 10.7.2004 (not 5.9.2004)
Last Pressure Test
The date shown on the last year’s label should be filled in the new label. If last year’s label
becomes dilapidated or the date cannot be seen when carrying out the maintenance works, the
condition of the extinguisher body should be checked to ascertain whether a pressure test is
required. If the year of manufacture shown on the extinguisher body exceeds 5 years with no
record of pressure test, pressure test should be carried out instead of merely replacing the
parts or extinguishing medium.
(For fire blankets and sand buckets, “NA” should be filled in.)
7.
Year of Manufacture
According to all standards accepted by this Department from different countries, the year of
manufacture must be permanently marked or stamped on the extinguisher body. So the year
of manufacture can be checked out from the body. If there is only 2 digits, it means the last 2
digits of the year of manufacture, e.g. 99 means manufactured in 1999. For those non-high
9
pressure extinguishers (25 bars below) manufactured according to Malaysian Standard
MS1179:1990, it only requires the year of manufacture be clearly marked on the body, but for
those Malaysian products manufactured according to BS EN-3, permanent marking or stamp
for year of manufacture is shown on the extinguisher body.
(For fire blankets and sand buckets, “NA” should be filled in.)
8.
Maintenance Result
If the maintenance procedures for this inspection cannot be fully completed in accordance
with the guidelines in this Code and attained a satisfactory result, it should not be treated as
“PASS”. A cross by using two straight lines to join the opposite corners in the square for
“FAIL” should be marked, e.g.
means fail. Particulars of defects must be listed in
Part 3 of the relevant Certificate of Fire Service Installation and Equipment (F.S. 251).
Remarks :
Other than fire services licensing requirement or fire services requirement for new buildings,
if the portable equipment is a new one, which can be readily used without assembly or filling
of extinguishing media, and its year of manufacture shown on the body does not exceed one
year, a Certificate of Fire Service Installations and Equipment (F.S. 251) is not required. The
relevant purchase receipt should be retained for future identification. In case the year of
manufacture of the portable equipment exceeds 12 months (i.e. 1 year) or the extinguisher
requires assembly or refilling, then the portable equipment should be inspected by a
Registered Fire Service Installation Contractor and a Certificate of Fire Service Installations
and Equipment (F.S. 251) be issued to prove its function.
