Half empty or half full?

So we've reached the end of NCG 1, the management of Health and Safety. Although I’ve found the teaching method less than inspiring, I do feel it's been worthwhile. There’s no rocket science in NGC 1. It's stuff we pick up in the process of working with health and safety. But it's stuff we might normally have difficulty explaining in a coherent way. Like we all know the difference between civil and criminal law don’t we? But can we list 6 differences, including maximum penalties for each? I don’t think I’ve learnt any thing completely new, but I feel I have a better structure for explaining what I already knew. For example, we can all agree that organisations should do health and safety, but structuring an argument for it around moral, legal and financial reasons is more convincing than "because we should"; I could previously have rambled on about "safe systems of work", but breaking it down into safe environment, safe equipment, safe material and safe people helps to prompt a more comprehensive description, and show that it needs more than common sense to get it right.
