Pressure Systems
Frequently Asked Questions

What is meant by 'Pressure System'?
Pressure Systems include all plant/systems that contain a relevant fluid, defined as steam or gas under pressure, and liquids under pressure which become gases upon release to the atmosphere, at a pressure greater than 0.5 bar (about 7psi) above atmospheric (except for steam). 

 

 

Are any pressure vessels exempt?
Yes. Certain small vessels are exempt from some parts of the Regulations. 

 

Are any steam pressure systems exempt?
No, where the relevant fluid is steam, all the regulations apply, irrespective of the vessel pressure.

 

Where are Pressure systems found in the BBC?
Around the BBC there are heating, fuel transfer, compressed gas and hydraulic systems used in program production (such as camera peds), studios, office and maintenance facilities.

 

Who is responsible for the pressure systems?
For installed systems (fixed in a permanent location) the user is responsible for ensuring that, maintenance, safe operation, operation limits and training is carried out.  In the case of mobile systems (frequently moved from place to place) the owner is responsible.

 

Who can maintain pressure systems?

Only competent persons may work on plant/systems/vessels/cylinders containing pressurised gases at more than 0.5 bar above atmospheric, or steam at any pressure. This includes camera pedestals. The rules cover all associated pipe work and any protective devices/ components designed to achieve system safety.

 

 

What is a 'Competent Person'?
The references to a "competent person" in the PSS Regulations should be taken to mean an organisation employing individuals who are competent (by knowledge, experience and independence) to carry out the relevant duties.  Accreditation to BS EN 45004 : 1995 [General criteria for operation of the various types of bodies performing inspection] is an indication of the competence of an inspection department, organisation or self-employed person.  This is recommended for bodies acting as competent persons engaged to draw up or certify a written scheme of examination or conduct examinations for major systems.
