UCL Safety Services
Pressure systems – managing the risks:
examination and testing
Scope
1.
This standard applies to all pressure systems used by employees, i.e. staff and post-
graduate students, at UCL. Specifically it details the arrangements to ensure that such systems
are examined by competent persons in accordance with a Written Scheme of Examination (WSE).
2.
Arrangements for all other aspects of the management of pressure systems are detailed in
Safety Services guidance (for Departmental systems and equipment) and UCL Estates Standard
Operating Procedures (SOPs) for Estates owned systems and equipment.
Legal requirements
3.
The Pressure Systems Safety Regulations 2000 (PSSR) require UCL to:
Provide safe and suitable equipment and know the safe operating conditions of that
equipment;
Fit suitable protective devices and ensure they function correctly;
Carry out suitable maintenance;
Make provision for appropriate training; and
Have the equipment examined by a competent person(s).
Definitions
4.
Pressure systems are defined as:
a system comprising one or more pressure vessels of rigid construction, any associated
pipework and protective devices
the pipework with its protective devices to which a transportable pressure receptacle is, or
is intended to be, connected
a pipeline and its protective devices
5.
A relevant
fluid
is:
steam at any pressure
any fluid or mixture of fluids which is at a pressure >0.5 bar above atmospheric
a gas dissolved under pressure in a solvent (acetylene)
6.
Relevant fluids do not include hydraulic oils. Hydraulic systems, while using high pressures,
do not store energy in the system and so are not covered.
