I don't know of any courses, certainly not ones that'll be relevant to your job, but it may help you to learn how to spot the difference between the two different sorts of health and safety officer. There are some health and safety officers who will make a rule, merely because it gives them a warm, tingly feeling, and makes them feel all important. And then there are the ones who will actually look at things realistically, and make sensible rules that people can work with. In my experience, the second group are actually more plentiful than the first group (although they're also quieter, so you may not notice them), and the second group also hate the first group for giving their profession a reputation for being filled with jobsworths. To be honest, you may as well try your hardest to annoy the first group, because they'll never end up on your side. A H&S bod in the second group is a valuable asset, though. Keep them sweet.
