Teach children to never touch or play with a gun or ammunition. If they see ammunition, a gun, or anything that looks like a gun, they should leave the area and tell a grown-up immediately.
If you have firearms in your home, keep them unloaded. Lock guns and ammunition in separate locations out of children's sight and reach.
Talk to the parents of your children's friends to find out if they keep a gun in the home. If they do, verify that it is kept unloaded and locked away where children can't see or touch it.
