Are you a user of 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 are the right materials being used in the manufacturing process 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.
