Using pressure systems

A pressure system is one that contains or is likely to contain a relevant fluid over 0.5 bar.

The main legislation covering the duties of a user of pressure equipment is the Pressure Systems Safety Regulations 2000 (PSSR).

In general terms the user must do the following:

Provide safe and suitable equipment - for example is the equipment suitable for its intended purpose and installed correctly and are modifications/repairs being carried out properly?
Know the operating conditions - including the characteristics of the relevant fluid in the system and the safe operating limits of the equipment.
Fit suitable protective devices and ensure they function properly - for example devices such as safety valves, bursting discs and electronic appliances, and ensure they are adjusted to their correct settings and in good working order at all times.
Carry out suitable maintenance- including a whole-system maintenance programme that considers factors such as age, uses and the environment in which it is operated.
Make provision for appropriate training - so that anybody who operates, installs, maintains, repairs, inspects or tests pressure equipment has the necessary skills and knowledge to carry out their job safely. Refresher training should be included.
Have the equipment examined - as required under PSSR, including production of a written scheme of examination (WSE), to be used by a competent person to carry out the examination - details in the PSSR Approved Code of Practice (L122).
Choose a competent person - ensuring they have the necessary knowledge, skills and, importantly, independence to undertake their role and responsibilities effectively.
