Yes it can. Moisture is obviously a bad thing and can ruin it, but age makes BP unstable. I was once told that if you can see white crystals that have formed in or on BP to soak it with oil and dispose of it. I don't know how accurate that advice is......IF AT ALL, but I I do know that old powder becomes unstable and the safest way to store it is air -tight container in a fridge. Take it for what it's worth
Plastic creates static electricity. The idea with tin is it can be theoretically grounded.
I've hauled fuel and oil over the years. Plastic pails for catching spillage, is a no-go. Metal pails only that have a grounding strap.
