>In this case, I'd be far more concerned about splashing the stuff on your hands or arms when pouring the acid out of the container, so I'd suggest that the less handling, the better. I use a plastic siphon pump (home wine or beer makers' supplies) to decant from bulk to a gallon container. I then pour from the gallon container on to pads on the top of the stack of boxes to be sterilised; this seems to me to be the most dangerous time for splashes, so I add an empty super to the top of the stack before I pour so that any splashes are then contained. As I often do this in the field, I always have a gallon container of water with me.
