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 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. 

Most credible initiating events and their fi equencies can be gathered either from the company s incidents library or from agencies such as CSB (Chemical Safety Board in US), CIMAH (Control of Industrial Major Accident Hazards in US), COMAH (Control of Major Accident Hazards in UK), European Seveso H Directive and HSE (Health and Safety Executive in UK).

In the UK, the Seveso Directives led to the creation of the Control of Industrial Major Accident Hazards (CIMAH) regulations in 1984. These regulations required manufacturers of hazardous chemicals to create a Safety Report— in effect a Safety Case. They also had to show how the hazards were being effectively managed. CIMAH was replaced by Control of Major Accident Hazards (COMAH) in 1999. 

CIMAH An abbreviation for Control of Industrial Major Accident Hazards, which were UK regulations issued in 1984. Since 1999 they have been superseded by the COMAH regulations. 

Hazard analysis. The concept of hazard analysis (or HAZAN) is widely used in the UK chemical industry and is a recognized part of the approach to the Ck>ntrol of Industrial Major Accident Hazard Sites or CIMAH legislation. 

In the United Kingdom an advisory committee was set up by the Health and Safety Executive (HSE) to review the problem and recommend procedures for the control of these sites, HSE (1976, 1979). Subsequently, a series of directives and amendments on this subject were issued by the European Economic Commission (EEC), and the EEC directives were implemented in the UK by the publication of the Control of Major Industrial Accident Hazards Regulations, 1984 (the CIMAH regulations). 

Safety eases entered the UK safety world as a result of the Control of Industrial Major Aeeidents Hazards regulations (CIMAH regulations) in 1984. Safety case principles were further examined and developed by Lord Cullen in his report into the Piper Alpha disaster (Cullen 1990) in which a major accident in an offshore oil facility in the North Sea resulted in 167 deaths. As a result of this report, the approach to offshore safety shifted from compliance to achievement of safety objectives. A safety case would demonstrate through argument and evidence that the required safety objectives would be met. Regulations laid down what must be addressed in a safety case.
