DAF Safety Hall of Fame induction is a lifetime, one-time distinction, and as a consequence, inductions are infrequent. The award recognizes United States Air Force and Space Force military or civilian personnel who have made unique contributions to Air Force or Space Force safety. These contributions must be made over an extended period and must result in enduring, unprecedented, and significant improvements to Air Force or Space Force safety. The awardee's performance and contributions are generally recognized by his or her peers as being of exceptional excellence and of quantifiable value to safety.
