The H&S risk is that you expect it to be light and do not position yourself for a heavy lift...also works in reverse you see a box of lead and go to pick it up and its just teh box it is very easy to hurt your self.

Legionella should not be a problem..it is found in soil but needs to be at 37o to proliferate. Also you then need to breath the spores to get infected. The main Legionella problem is Aircon cooling tanks.
