"On August 21, 2017, a total solar eclipse will be visible in a path across the U.S. from Oregon to South Carolina, from early morning through the afternoon. It is expected that millions will travel to locations across the country to view this rare event. […] Many of these locations are rural with limited healthcare infrastructure, and since these sites are not (yet) officially sponsored, the typical augmentation of resources that accompanies planned mass gatherings will not take place. To address planning and response concerns and help local emergency healthcare providers plan for these gatherings, the ASPR TRACIE [Assistant Secretary for Preparedness and Response; Technical Resources, Assistance Center, and Information Exchange] team collected the following fact sheets, checklists, locally-developed guidance documents, and news articles on eye safety, injury treatment, and planned mass gatherings in rural and urban areas. Resources in sections I through V are specific to the eclipse event; the rest of the sections include resources related to planned mass gatherings."
