Safety & Security Assurance

The effective implementation of functional safety standards, practices and processes is increasingly important in ensuring that Safety Instrumented Systems are appropriately specified, designed installed and maintained. BS EN 61508 and the process sector specific functional safety standard BS EN 61511 promote the concept of the safety lifecycle. In addition, Safety assurance in line with EN 51026, 28 & 29 has been long established within the rail sector. Experience shows that engaging experts early in the design process has a positive impact on projects.
