OnStream Traditional Maintenance ServicesAt BOC safety is our top priority. We understand that complying with safety legislation is a necessity, but it can be time consuming and complicated, requiring a detailed understanding of engineering, gases and regulations.

At BOC we know exactly what is required to conform to safety legislation such as Pressure Systems Safety Regulations 2000 (PSSR) and have developed our OnStream service to assist you in achieving the required full compliance.


Currently any owner or user of a gas system which is pressurised above 0.5 bar (g) must be able to demonstrate the following:

  • the system is working within safe operating limits
  • a Written Scheme of Examination (WSE) is in place
  • the system is regularly maintained and inspected by a competent body

It is a legal requirement to conform to PSSR.  Failure to do so means your system is at risk of being shut down until compliance has been achieved.

BOC OnStream

The BOC OnStream service is designed for owners of fixed pressure systems - ranging from simple systems with a single regulator and short distribution pipe work to longer, more complicated systems with many control and outlet points.

Even if your equipment is currently in 'poor' condition, we can assist you in upgrading your system to improve safety whilst delivering PSSR compliance, allowing you to concentrate on your core business.

As part of The Linde Group, BOC recognises that safety is the top priority around the globe.

Our knowledge and understanding of the requirements to conform to PSSR legislation have been developed over many years. 

BOC OnStream will help you achieve full compliance.
