Revitalising Safety & System Assurance   Welcome to our web site, which gives information about the domain we work in, how we can help solve complex safety concerns and provides a useful library of publications and relevant references for the safety management domain.  RS2A is a small engineering consultancy offering expert opinion and resource effort in the field of safety engineering and system analysis. We specialize in safety case construction, hazard and risk analysis and system assurance in a variety of domains including defence, aerospace, automotive and civilian industry.  We believe that everyone's safety concerns are important, so we do prefer to spend time understanding the problem space with clients before creating and delivering solutions.
