Pressure Systems Safety Regulations
PSSR – Pressure Systems Safety Regulations – (2000) lay down the legal requirements aimed at preventing serious injury from the hazard of stored energy as a result of the failure of a pressure system or one of its component parts.
A pressure system is defined as:

A pressure system is defined as:
- a system comprising one or more pressure vessels of rigid construction, any associated pipework and protective devices;
- the pipework with its protective devices to which a transportable pressure receptacle is, or is intended to be, connected; or
- a pipeline and its protective devices, which contains or is liable to contain a relevant fluid.
- steam;
- any fluid, or mixture of fluids, which is at a pressure greater than 0.5 bar above atmospheric pressure, and which fluid or mixture of fluids is:
– a gas; or
– a liquid which would have a vapour pressure greater than 0.5 bar above atmospheric pressure when in equilibrium with its vapour at either the actual temperature of the liquid or 17.5ºC; or - a gas dissolved under pressure in a solvent contained in a porous substance at ambient temperature and which could be released from the solvent without the application of heat.
