Pressure System Safety Regulations (PSSR) 2000

Contact us

The Pressure System Safety Regulations (PSSR) 2000 covers various aspects of a system’s safety, from design through construction, then covering any subsequent repairs or modifications, and requires owners/users to have a Written Scheme of Examination certifying that their system is safe for use.

Complying with various regulations can be challenging. The PSSR requires that the Duty Holder (the owner or user) must ensure their systems have a Written Scheme of Examination, issued by a Competent Person (such as VELOSI) which certifies that it is safe for use. The content of the Scheme must be reviewed at regular pre-determined intervals based upon an examination of the system; again, it is the Duty Holder’s responsibility to ensure that the periodic examinations are carried out according to schedule.

As a certified Competent Person, Velosi is able to give impartial advice as to how to best meet the regulations. We can also carry out any technical inspections or assessments and issue the Written Scheme of Examination according to the regulations.

Our solution
VELOSI is certified to act as a Competent Person, and therefore has the capability to issue a Written Scheme of Examination upon inspection of a Duty Holder’s system. We will conduct an inspection of the system for anything that may give rise to a dangerous situation and ensure that it is safe and suitable for its intended use. We will also determine a schedule of future examinations after consultation with the Duty Holder.

We have our own internal database of all the systems and schemes we have certified and are therefore able to issue reminders to the Duty Holders, helping them guarantee that their responsibilities are fulfilled.

The PSSR covers various types of systems. However, there are some criteria that determine whether a system is included or not. These are concerning stored energy (Pressure x Volume), steam scalding, the relevance of the fluid contents and specific exclusions.

The following are examples of where the PSSR legislation would apply:

  • Boiler systems for schools, hospitals, shopping centers and office buildings
  • Compressed air systems in garages and workshops (but not the associated tools)
  • Premises where autoclaves are used, i.e. dentist offices.
  • Power stations
  • Petrochemical complexes
  • Process plants

Under the regulations, it is the Duty Holder’s responsibility to ensure compliance. The Duty Holder can be either a person or an organization and can range from the user or the owner, and can in some cases be the designer, manufacturer or seller. Once in use, the Duty Holder is responsible for ensuring that the system is not used until it has a Written Scheme of Examination for the periodic examination.

The Written Scheme of Examination defines the type of inspection, including any non-destructive examination, pressure testing, visual and dimensional check. The extent of the inspection such as full internal, full external with all lagging removed etc.; defines the periodicity of the inspection. This is based on the process’ severity and the Competent Person’s judgment for the equipment to remain safe under the existing working conditions.

It is often considered that the PSSR covers all aspects of a pressure system’s safety. However, it is only relevant to the potential for release of stored energy or steam, which could cause harm. It is also usually considered that the PSSR is related to insurance. However, they are actually separate issues and need not necessarily be carried out by an insurance company.

VELOSI’s internal controls maintain a database of systems and schemes that it has certified and is able to ensure that reminders are issued to Duty Holders so their responsibilities can be maintained.

By fulfilling the PSSR requirements, the Duty Holder safeguards against any potential dangers that might emerge from its system being unsafe and unsuitable for use. This will ultimately result in savings as it will limit injuries and unscheduled time delays.

With VELOSI’s services, a Duty Holder not only fulfills its responsibility to get a Written Scheme of Examination for his system but also ensures that he never misses a periodic examination that may affect his Written Scheme.
