You can be as anal as you like, but what you do should probably depend on the amount of materials that you handle or store, and how confined it is. I know people resent OSHA for proposing rules to make workplaces more safe, but I think there are guidelines that can be found online. Just as one may be free not follow gun safety rules, that doesn't make it a good idea.
This is not small arms related, but I work as a consultant at a facility that is in the ballistic missile business. Wherever certain solid rocket fuel components or explosives are handled, the floors are painted with conductive paint containing carbon fiber, we wear conductive shoes (black rubber soles containing carbon fiber), and everything is grounded wherever the fuels and explosives are handled. Even with all that, bad things happen that one never reads about.
Given the frequency of unexplained explosions in Gaza basements, I suspect that some terrorists don't think these procedures are very macho.
