Second responder
A second responder is a worker who supports "first responders" such as police, fire, and emergency medical personnel. They are involved in preparing, managing, returning services, and cleaning up sites during and after an event requiring first responders. These sites may include crime scenes and areas damaged by fire, storm, wind, floods, earthquakes, or other natural disasters. These types of services may include utility services (shutdown or reinstatement of electrical, gas, sewage, and/or water services), wireless (3G/4G/WiFi) or wireline communication services, specialty construction (i.e. shelter construction), hazardous waste cleanup, road clearing, crowd control, emergency services (i.e. Red Cross), first aid, food services, security services, social services (i.e., trauma counselors), and sanitation.
