Ammunition and Components
Do not lose sight of the importance of providing safe storage for ammunition and ammunition components. Gunpowder, black powder, primers, and percussion caps are themselves extremely dangerous to children, and should be secured as carefully as your firearms. Tales abound of experienced firearms owners keeping open containers of black powder in workshops near spark-producing grinding machines. Situations like this can result in tragedy.
Note: Some states, such as California, Massachusetts, Hawaii, and others, have enacted legislation regarding responsible firearm storage. Check with the office of your state's Attorney General or Police Department for information regarding any legal requirements for safe storage.
