The course explains why system safety management and a safety culture are important and the associated legal framework. It looks at the concepts of system safety engineering, the principle of as low as reasonably practical and managing risks. It covers safety cases, safety audits and safety governance and sequencing system safety activity in a project cycle. The course is set against a context of the MOD project environment but the principles have a wider applicability and are also suitable for members of safety committees as well as project teams. The course is an element of a mandated programme for MOD system safety practitioners leading to an International Institute of Safety Risk Management accreditation, but has wider relevance to non-MOD employees involved in the system safety aspects of projects.
