First responder

A first responder is a person with specialized training who is among the first to arrive and provide assistance or incident resolution at the scene of an emergency. First responders typically include law enforcement officers, emergency medical services members, fire service members and Public Works employees such as Heavy Equipment Operators as well as Public Works Tree Department personnel. In some jurisdictions, emergency department personnel, such as doctors and nurses, are also required to respond to disasters and critical situations, designating them first responders; in other jurisdictions, military and security forces may also be authorized to act as first responders.
