1What is the primary statutory purpose of the UK Pressure Systems Safety Regulations 2000 (PSSR)?

A.To prevent serious injury from the release of stored energy resulting from the failure of a pressure system or one of its component parts

B.To regulate energy efficiency ratings for industrial pressure boilers across the United Kingdom

C.To establish manufacturing quality standards for new pressure vessels prior to market placement

D.To enforce environmental emission limits for pressurised gas processing facilities

Explanation: The primary statutory objective of PSSR 2000 (S.I. 2000 No. 128) is to prevent serious injury caused by the catastrophic release of stored energy during the failure of a pressure system or its component parts.

2Under PSSR 2000, what is the minimum gauge pressure threshold for a relevant fluid consisting of a gas or steam?

A.0.5 bar gauge (0.05 MPa)

B.1.0 bar gauge (0.10 MPa)

C.2.0 bar gauge (0.20 MPa)

D.0.1 bar gauge (0.01 MPa)

Explanation: Under Regulation 2 of PSSR 2000, a 'relevant fluid' includes steam at any pressure, or a gas dissolved under pressure, or a gas with a vapor pressure greater than 0.5 bar gauge above atmospheric pressure.

3Under PSSR 2000 Regulation 8, who has the legal duty to ensure a Written Scheme of Examination (WSE) is drawn up and certified?

A.The User of an in-service pressure system or the Owner of a mobile pressure system

B.The Original Equipment Manufacturer (OEM) of the pressure vessel

C.The Health and Safety Executive (HSE) factory inspectorate

D.The Non-Destructive Testing (NDT) Level II technician executing the inspection

Explanation: Regulation 8(1) of PSSR 2000 explicitly places the statutory duty on the User of an installed pressure system (or Owner of a mobile system) to ensure that a Written Scheme of Examination is drawn up and certified by a Competent Person.

4Which document provides the HSE Approved Code of Practice and guidance for complying with PSSR 2000?

A.HSE L122

B.HSE L8

C.HSE L21

D.HSE L74

Explanation: HSE publication L122 is the Approved Code of Practice (ACoP) and guidance titled 'Safety of pressure systems: Pressure Systems Safety Regulations 2000'.

5What key distinction exists between the Pressure Equipment Regulations 2016 (PER) and PSSR 2000 in the UK?

A.PER regulates design, manufacture, and placing on the market of new equipment, whereas PSSR regulates safe operation and in-service examination

B.PER applies only to steam boilers, whereas PSSR applies exclusively to refrigeration plant

C.PER is enforced by the Police, whereas PSSR is enforced by local municipal councils

D.PER regulates offshore diving chambers, whereas PSSR regulates land-based nuclear reactors exclusively

Explanation: PER 2016 (transposing the EU PED) applies to the design, conformity assessment, and initial placing on the market of new pressure equipment. PSSR 2000 governs the ongoing operation, maintenance, and statutory inspection of pressure systems during their operational life.

6Under Regulation 7 of PSSR 2000, what must the User or Owner establish before operating a pressure system?

A.Safe Operating Limits (SOL) for pressure and temperature

B.An insurance replacement value policy

C.A 10-year capital expenditure schedule for vessel replacement

D.A full environmental impact assessment report for carbon emissions

Explanation: Regulation 7 requires the User/Owner to produce a document specifying the Safe Operating Limits (SOL) for the system, including maximum/minimum allowable working pressures and operating temperatures.

7What information MUST be specified in a Written Scheme of Examination (WSE) according to PSSR 2000 Regulation 8?

A.The items of plant included, nature of examination, maximum intervals between examinations, and any preparation required

B.The purchase price, serial number of the paint batch, and supplier delivery driver details

C.The annual electricity consumption of feed pumps and backup diesel generator fuel ratings

D.The names of all shift operators and their shift rotation pattern

Explanation: Under Regulation 8, a WSE must specify all protective devices, pressure vessels, and pipework included in the scheme, the nature and frequency of examinations, and the preparatory work necessary to allow safe inspection.

8Following a statutory examination under PSSR 2000 Regulation 9, within what timeframe must the Competent Person send a written report to the User?

A.Within 28 days of completing the examination

B.Within 7 days of completing the examination

C.Within 90 days of completing the examination

D.Within 6 months of completing the examination

Explanation: Regulation 9(3) stipulates that the Competent Person must make a written report of the examination and send it to the User/Owner within 28 days of completion.

9If an examination under PSSR Regulation 9 reveals that the pressure system gives rise to imminent danger, what immediate action must the Competent Person take?

A.Notify the User immediately and send a written report to the enforcing authority (HSE) within 14 days

B.Issue a verbal warning to the operator and wait until the next scheduled shutdown

C.Apply a temporary weld repair without notifying site management

D.File a report with the local police department within 48 hours

Explanation: Under Regulation 9(4), if the Competent Person identifies imminent danger, they must inform the User immediately and send a copy of the report to the enforcing authority (HSE or Local Authority) within 14 days.

10Which of the following items is explicitly EXCLUDED from the scope of PSSR 2000 under Schedule 1?

A.Pressure equipment forming part of any braking system of any road vehicle

B.Stationary shell steam boilers operating at 10 bar gauge

C.Process plant air receivers with a volume of 500 liters operating at 8 bar

D.Refinery hydrocracker reactors containing hydrogen gas

Explanation: PSSR 2000 Schedule 1 lists pressure systems exempted from the regulations, which includes braking systems of road vehicles, aircraft pressure systems, and certain pipeline systems covered by separate legislation.
