Anyone that responds to an emergency that is not immediately on the scene when it happens. Ex: police, firefighters, paramedics.
The true first responders are those who are at the scene when the emergency starts and the second responders arrive during or after the situation has already been resolved.

Get the Second respondermug. A second baseman is a person is either baseball or softball that plays second base. They typically do not get much hit to them but when they do they are on their toes. Their specialties include covering first and second as well as covering the base in a run down which they always enjoy. Typically the most enthusiastic on the team and hyper about getting to play their position. Second basemen always rock a face mask when chosen. Most second basemens take possession over the base second and are very protective over their spot.
Person 1: “dude did you see how hyper she was covering second for that run down!!”
Person 2: “yep! She must be the second baseman.”
Person 2: “yep! She must be the second baseman.”
