Don't use a regular vacuum cleaner for clean-up around the reloading bench. The problem is created by the vacuum bag not collecting and holding all the material it sucks up. If you ever disassemble a house vacuum cleaner for maintenance you will understand why.
A good quality shop vacuum is another situation. The electric components of this type vacuum cleaner is sealed from dust, water, etc. Therefore, you should not experience a problem when using it around your reloading bench. The reason is the way the vacuum cleaner draws in the material and the surrounding air. In a shop vacuum cleaner, neither the material nor the surrounding air passes through or near the electric motor which is where the problem with the home vacuum cleaner begins.
Of course, safety is the primary issue here. So if the clean-up is small, then manual labor is the safe method. But if the spill is large, a good quality shop will do the job safely.
