Russ I think this is a problem we all face in this industry, we are very good at producing new and amended documents but not so good at ensuring personnel are familiar with them. So, I suggest you make sure they are easily accessible via an intranet site and health and safety section. You may need to do a presentation or workshop to promote the h&s section. Ideally documents should use hyperlinks so it is easy for the end-user to navigate from one document to another. New starters should especially be given a heads-up so they know from the off where to refer to documents they may need. You might think about doing an internal audit to see how many people are aware of the h&s documents, how often they use them, do they find them useful, user-friendly, etc. Finally, when carrying out accident/incident investigations include whether those who were involved or their immediate Line Manager were familair with the policies and procedures related to the incident - probably not!
