Operating graphic standards or guidelines

Not a proper answer, but, in my experience all too often the suppliers give the P&ID's to a trainee to develop the graphics. And they get corresponding results. IMHO P&ID's should NOT be used as basis for graphics. And graphics designers should understand the process and operational requirements. Francis

The Abnormal Situation Management Consortium produce quite comprehensive guidelines for operator graphics. Some of their material is available for download online, but their standards are only available to members of the consortium. Check out

There is an ISA Technicakl Report TR 77.60.04 which gives some general guidelines. The UK HSE are also working on a document with guidelines in HR factors for safety-related systems which will be interesting when it appears.
