HAZOP and Water Issues in Hygienic Industries

I chaired a HAZOP this week, which I was trained in a long time ago, and still do on occasion, focussing on hygienic issues in a nutraceutical plant.  As ever, we all learned something, even the guys who had been operating the plant for thirty years. HAZOP is a powerful tool.

I've also been looking at a few water issues, and I was once again reminded of so many past experiences of people assuming water is simple. I have seen examples of under and overspecification this week. How to avoid this? Ask a water specialist. It is a false economy not to.
