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.
