U.S. Senators Amy Klobuchar (D-MN), Jon Tester (D-MT), and Marsha Blackburn (R-TN) introduced legislation to ensure that servicemembers and veterans exposed to Occupational Environmental Health (OEH) hazards in the line of duty get the necessary medical care and benefits they need. The bipartisan Occupational and Environmental Transparency Health (OATH) Act would require the Department of Defense to track active duty military personnel and veterans’ exposed to harmful chemicals in a system. Currently, individuals who have been exposed to toxic chemicals such as mold, caustic fumes, open air burn pits, and airborne chemicals during military operations are not being properly documented and tracked by the Defense Department or VA. Out of a total of more than three million post-9/11 veterans, only 175,000 veterans and service members are registered under the VA’s Airborne and Open Burn Pit Registry. The OATH Act calls for three major changes. It requires the Defense Department to include in a servicemember’s health records any toxic exposures, either at home or while deployed, conduct a post-deployment health assessment, and update veterans’ health records based on information submitted to the VA’s Airborne Hazards and Open Burn Pit Registry.
