<div><br></div><div>I hope you can convince them to map these sorts of things in addition to whatever hazard level tagging system you come up with. Personally I don't mind if they add some sort of subjective hazard level tag as well as these objective tags, but I think the objective tags will be much more useful in the long term.</div>
