This message reinforces the Department of the Navy's commitment to safeguarding our personnel by raising awareness of brain injuries and establishing a process of improvement for treatment and management of operational activities that may risk brain injuries. 2. After several decades of combat operations and warfighter-related research, we continue to learn that some injuries are difficult to diagnose. Unlike other types of injuries, traumatic brain injuries (TBI) may not manifest immediately, and exposure to multiple blast overpressure or impacts may have a cumulative effect that we are only now understanding. We are modifying operational procedures to minimize the risk to warfighters. The science regarding these exposures and impact thereof is evolving, but waiting on definitive answers is not an option. 3. As we are learning, TBI may occur from impacts to the head as well as exposures to explosions, blast overpressure, or from the operation of various weapons systems. All of these events may contribute to injuries in a multitude of ways (impulse noise, blast overpressure, body accelerations, and whole body vibration). These exposures may occur in combat, operational, and training environments. The Department of Defense (DoD) Blast Injury Coordinating Office site, shown in reference (a), is a good resource of information that supports the Services. In the training environment, it is critical we maximize weapons proficiency to enhance our readiness and limit unnecessary exposure. References (b) and (c) require the identification and control of hazardous exposures. Reference (d) identifies blast overpressures of four pounds per square inch as a level of concern and directs the Services to keep exposures to as low as reasonably achievable. The Services currently accomplish this level of exposure through increasing stand-off distance from blast events and limiting the time and number of exposures. 4. Reference (e) identifies symptoms and shows that early intervention is paramount in preserving the health and readiness of our personnel. Resources for identification of symptoms are available at reference (f). We must renew our awareness and vigilance in protecting our Sailors and Marines from brain injury threats. Additionally, it is also important to emphasize the entire DoD, Navy, and Marine Corps assets in the medical, occupational health, and medical research communities remain fully committed to working together to minimize the risk of brain injury to Navy and Marine Corps personnel. 5. Commanders and Commanding Officers: a. Incorporate brain injury awareness into your command's safety and health programs and emphasize the importance of brain injury prevention, identification, and treatment. b. Ensure range protocols comply with the limits defined in references (f) and (g). c. Ensure safety offices are identifying hazardous exposures from unit level operations and assessing control measures as required in references (a) and (b). d. Ensure medical departments are aware of symptoms and interventions for brain injuries and resources available from references (h) and (i). e. Discuss brain injury awareness during unit level safety events. Additional resources are available at reference (g). 6. All personnel shall: a. Exercise caution and minimize unnecessary exposure. If exposed and not actively engaged in developing proficiency, take action to minimize exposure. This may be as simple as taking a couple of steps back. b. Be mindful of symptoms of potential brain injuries in oneself and others. c. Report suspected brain injuries to medical department and chain of command. d. Strict adherence to established tactics, techniques, and procedures is critical to ensure exposures are controlled or minimized. 7. It is the responsibility of every Sailor, Marine, and civilian to minimize potential brain injuries. By staying vigilant and being proactive, we enhance our collective ability to protect the mission and the safety of our personnel. 8. Let this serve as a reminder that preventing and treating brain injuries is not a one-time effort but a continuous commitment. Our success relies on the diligence of every Sailor, Marine, civilian, and contractor in safeguarding or operational capability. Together, we can maintain a secure environment that ensures the accomplishment of our mission objectives, maximize readiness, and minimize exposure to ensure the safety of our Nation. 9. I encourage you to learn more and take advantage of the excellent resources available in designated references which are aggregated on the Deputy Assistant Secretary of the Navy Safety webpage (https://www.secnav.navy.mil/eie/Pages/default.aspx) under Blast Overpressure. 10. Released by the Honorable Carlos Del Toro, Secretary of the Navy.// BT #0001 NNNN CLASSIFICATION: UNCLASSIFIED//
