Implementation of Safety Case requires in process plants requires in-depth knowledge of related Functional Safety standards, personnel training and organizational management structures among others. Usually, an independent technical organization is engaged by the plant owners to support, assess or inspect the project.

Explosion Protection in Safety Case
Within many process industries, there are lots of flammable or combustible substances produced, used, and stored, creating hazardous areas with a risk of fire and/or explosion. In some countries, such hazardous plants are required to produce a Safety Case, and having a structured approach on Explosion Protection could provide a great help in the preparation, from identification, selection of equipment, and operations.
The Safety Case concept has been around for many years. They have been used in the nuclear and aviation industry for a long time and were introduced to the Oil & Gas and Petrochemical industries as a result of the Cullen Enquiry into the Piper Alpha disaster in 1988. No matter the industry, Safety Cases regimes are designed to help the owner/operator of a facility to show stakeholders that the facility is being managed and operated in such a way that reduces the probability of a major incident and that if a major incident did occur, the effects of that incident will be minimized.
Leading regulations and standards, such as the Safety Case requirement in Singapore, emphasize that Major Hazard Installation (MHI) operators should take into account all likely risks, and these must surely include those relating to cybersecurity.
The number of cybersecurity-related incidents in industrial control networks has risen in every region in recent years, and there have been well publicized reports of sophisticated malware and threat actors disrupting safety instrumented control systems.
Organizations operating industrial facilities have a responsibility to monitor, detect, and mitigate cybersecurity attacks in order to maintain the safety, integrity and availability of their plant which, if compromised, may have a severe and detrimental impact on society.
The trend to digitization and system inter-connectivity means that operational technology engineering and operating personnel may not realize the full extent of cybersecurity vulnerabilities they face and are thus inadequately prepared to deal with potential attacks.
