Assessing the compliance of Hardware Design activities for a number of sub systems that implement SIL safety functions against the relevant clauses of BS EN 61508-2.
Subsequently produce the Compliance Matrix to indicate the compliance status and either planning to obtain any shortfall of evidence or producing the evidence as appropriate.
For each equipment, liaising with the subsystem safety engineer to understand the SIL Hardware safety functions for which BS EN 61508-2 compliance evidence is needed. This will vary considerably between equipments. This will provide scope for the subsequent tasks.
The subsystem safety engineer is responsible for identification of which safety functions are relevant. The contractor is not expected to support doing this. For each relevant clause in the BS EN 61508 compliance matrix review the current Hardware Design activities/evidence, to see if appropriate compliance evidence already exists. If so, this can be referenced in the compliance matrix.
This is expected to be the case much of the time. If appropriate existing evidence doesn\'t exist, or only partially exists, new/additional evidence will be required.
A plan to generate the new evidence will need to be produced and agreed with the company. The evidence then needs to be generated according to the plan and appropriately documented. Depending on the nature of the evidence, producing and documenting may need to be done as part of the task. Alternatively it may be done by others and the task will involve reviewing its appropriateness and assessing whether it supports compliance with the clause.
