B) PRESSURE VESSEL
OBTAINING APPROVAL FOR THE USE OF PRESSURE VESSELS
1. Before any pressure vessel can be used, approval must first be obtained from the
Chief Inspector of Factories.To obtain approval from the Chief Inspector of
Factories, the owner of the pressure vessel can complete the Application for
Registration of a Pressure Vessel form and submit it to the Chief Inspector of
Factories.
2. Submit the application form together with the following documents to:

registered;
b. a set of construction drawings of the vessel; and
c. for steam boiler, a set of boiler room and steam piping layout plans.
3. No pressure vessels shall be taken into use unless a. an application is made to the Chief Inspector who may assign an authorised
boiler inspector to carry out examination and test on the pressure vessel, and
b. a report of such examination and test issued by the authorised boiler
inspector has been obtained.
4. The pressure vessels shall be inspected by an authorised boiler inspector at the
intervals indicated below.
Steam boilers -
once every twelve months.

Air receivers -
once every twenty-four months.
once every twelve months.
once every twenty-four months.
5. Steam boilers in operation except electrically operated boilers shall be controlled by
a person holding a certificate of competency.
6. Refrigerating plant pressure receivers must be examined and reported on by an
authorised boiler inspector before use.
7. f the improper repair of any pressure vessel could be dangerous, approval must first
be obtained from the Chief Inspector before the repair is carried out.
8. Pressure vessel which contains any corrosive, toxic, explosive or inflammable
substance, and every part thereof and all its fittings and attachments, shall be of
good construction, sound material, adequate strength, and free from patent defect
and shall be properly maintained.
9. Gas plants
Every water sealed gas holder of storage capacity exceeding 25 cubic metres shall
be thoroughly examined externally by a competent person at least once every 2
years. A record containing the prescribed particulars of such an examination shall
be entered in a register.
For detailed requirements on pressure vessels and gas plants, please visit the Ministry of
Manpower website and also refer to the Factories Act.
