More Safety Precautions
Some other rules such as a maximum BB velocity and distance guidelines are used in different ways by groups depending on their location. Various locations often offer similar safety rules with slight variations. In order to encourage the mixing of segmented communities into a larger community that can more easily engage each other, certain organizations have created safety rules and guidelines for players to share the field under common understanding and to band together in safe environments.
Safety zone for airsoft guns is 1fps-399fps, that zone is probably the safest zone to play in, whereas the closest strike from a gun with 399fps would only make a welt, while anything below 200fps probably would feel like nothing at all. Any gun over 400fps can injure someone. For more information regarding velocity limits and BB ballistics refer to airsoft pellet ballistics.
