no, but they're gonna put plastic boxes on the "terrorist parphenalia" list, and only allow use of "preban" boxes....

"Plastic box" is very odd. Was it a glovebox, or not? Improvised, or off-the-shelf? And would a glovebox work under water, or would the gloves "blow out?" They are not designed for more than a very slight pressure differential. Just the weight of water in water-filled gloves would be much more than what they would have to handle in air. There ARE armoured boxes for working with explosives and rocket fuel, but these weigh a lot. Even a high school lab glovebox would weigh more than I'd like to carry by myself.
