Although the safety case is becoming fairly popular throughout the world, there are also regulatory requirements in regions other than the US for a similar safety case regime. This process of developing and maintaining a safety case model, is not be considered as a mere regulatory item but rather a safety based value proposition for the corporation. This essentially is a "cradle to grave" safety management system for the corporation.
In recent years, there have been several waves of discussions in the US to adopt the safety case model. Just like any new potential ordinance awaiting its buy-in from the industry, this has also been a case of differing opinions from the various industrial verticals.
However, getting back to the drawing board and taking a look at compliance towards any specific model, the industrial authorities need to take a step back and review the components of a safety case. Doing so will reveal that the majority of these requirements have been already met by the corporation on account of their compliance models – SEMS or PSM compliance or by way of due diligence. Looking at process safety as a moral responsibility of the corporation that extends for the life of the facility, it is clear that the majority of the requirements of the UK type of safety case model have been already met by US corporations.
This paper will compare and contrast the similarities and differences between the safety case model and the SEMS model. Both of these models are performance based, with variations falling into categories of who sanctions and/or enforces the respective models. The big success in the solution to this model puzzle is determining how effective the implementation of either in the field, and adheres to a proactive approach.
