Keeping Them in their Cases
Part of self defense safety is also keeping your tools out of the hands of children. Something like a Mace baton can come in handy, but you also want to make sure that it will not be used improperly by a child who thinks it’s a toy.
Though pepper sprays are not deadly like guns, it’s still a good idea to keep them out of the reach of small children by either placing them in a secure, locked storage box or putting them in a area that cannot be seen by the naked eye (behind a false wooden panel, perhaps).
