Independent Safety Assessment


An Independent Safety Assessment or Audit is often required before a product or system can be brought into service or enter the market. The principal aim of this activity is to show that the evidence for the safety claim exists and is valid. Audits or assessments take place against the safety requirements and often require knowledge of international standards and best practise.

To make a safety claim, it is not good enough to show that a product or system meets a particular standard. Many standards are overtaken by the technological progress and evolving best practise. To ensure that in the, hopefully, unlikely event of an accident and a claim for liability being made, then it is important that not only has there been a well documented and structured approach to the development, deployment and maintenance activities, but that the development activity took note of the evolving best practice and also where necessary the ALARP principal was used to reduce the risks to a tolerable level.

Virkonnen can either undertake the ISA role, or can help organisations put in place policies and practices to ensure that when an Independent Safety Assessment is carried out, the evidence is in place to ease the task.

Virkonnen's experience covers the functional safety standards BS EN 61508 and BS EN 61511, as well as for example Def Stan 00-55, 00-56 , RTCA 178B, RIA23, BS EN 50126, BS EN 50128 and BS EN 50129.
