Blood loss is the leading cause of preventable death in multiple-casualty events like mass shootings, terrorist attacks and earthquakes. Stop the Bleed training gives potential bystanders the skills and knowledge to provide immediate bleeding control and save lives. Training is free to the public and offered in eight western Washington locations. Harborview Injury Prevention & Research Center, along with the American College of Surgeons Washington State Committee on Trauma, Seattle and King County EMS and Harborview Medical Center work together to provide this lifesaving training to Washingtonians.
