Thanks to evryone for your invaluable replies and information. The links and reference material are fantastic.
Crossunder - The company I work for is unfortunately both smallish and low budget. We are however making slow progress in getting them to understand the importance and benefits of training, beyond satisfying Authority and Audit requirements. We do not have the appropriately trained personnel presently, but the people we do have are volunteers, motivated, and we are looking at options to advance their qualifications. But, as I said, slow progress.
Thanks again to those who replied.
