In the United Kingdom this is covered by the Control of Major Accident Hazards Regulations 1999 (COMAH), set up by the HSE (Health and Safety Executive) to implement the Seveso II directive of the EC (European Union) see www.hse.gov.uk. The COMAH regulations supersede the previous CIMAH (1984) regulations, set up under Seveso I. 

The aim of the COMAH regulations is to prevent major accidents involving dangerous materials from occurring and to mitigate the effects on people and the environment.

The concept of a safety case comes from the requirements of the European Union/European Community (EU/EC) Seveso Directive (82/501/EC) and, in particular, regulations that the United Kingdom and other member states used to implement that directive. United Kingdom regulations (Control of Industrial Major Accident Hazards [CIMAH], 1984 replaced by Control of Major Accident Hazards Involving Dangerous Substances [COMAH] in 1999) require that major hazardous facilities produce a safety report or safety case.64 The requirement for a safety case is initiated by a list of chemicals and a class of flammables. Like the hazard analysis approach (Section 8.1.2), experts identify the reactive hazards of the process if analysis shows that the proposed process is safe, it may be excluded from additional regulatory requirements.

The Hull site is a top-tier COMAH establishment and the individual plant safety reports were used as a base to identify the major hazard scenarios. While the Hull plants produce different final products, the key operational stages are the same, i.e., feed system, reactor section, initial separation and recycling, and final distillation train. The Risk Control Systems (RCS) were therefore fundamentally the same but each plant was reviewed in isolation. A total of eight different RCS were considered as part of the review and the process described in HSG 254 was used for each one. The Workbook produced during the review for one of the plants as part the process is attached in Appendix 1. ... 

In the recent past the capital value of the physical plant normally dominated the balance sheet. Today a number of companies have to include a greater provision to cover the potential costs of remedying problems or liabilities, associated with the plant such as land contamination or problems associated with either the use or abuse of the product or byproducts. Whilst in certain well-publicised cases these costs are indeed very substantial, many other companies are blighted by the possibility of the costs.

SI 1984/1902 implementing the so-called Seveso Directive (Council directive 82/501/EEC of 24 June 1982 on the major-accident hazards of certain industrial activities) and now replaced by the Control of Major Accident Hazard (COMAH) Regulations 1999 (SI 1999/743) which in turn implement the Seveso 11 Directive (Council Directive 96/82/EC of 9 December 1996 on the control of major-accident hazards involving dangerous substances, as amended by Directive 2003/105/EC). 

Nowadays, the great emphasis is put on safety prevention in different fields of human activities. One of these fields is the preparedness for major accidents and/or prevention of them, including elaboration of safety documentation for facilities, in which dangerous substances are hold in amounts exceeding limits mentioned in Annex I of the Council Directive 96/82/ES of 9 December 1996, on the control of major accident hazards involving dangerous substances, so-called SEVESO II Directive or COMAH . This Directive is implemented in the Czech legislation as the Act No. 59/2006 CoU., with later amendments (hereinafter called law ) that was established for prevention or minimalization of accident effects on hiunan health, property and environment.
