S.W.A.T. Paramedic

The Ontario Fire and Police Departments were one of the first agencies in the State of California to utilize paramedics in a tactical role; the year was 1985. In response to the needs of the Ontario Police Tactical Team, police and fire personnel were faced with the physical constraints of providing emergency medical care to injured citizens and police officers in a hostile environment.

Paramedics from the Fire Department were commissioned to Reserve Police Officer status and trained to the level of a S.W.A.T. Team Operator.  To date, there have been several high-risk incidents where the skills of the S.W.A.T. Paramedic have been placed into action.  The S.W.A.T. Team Paramedic is dispatched with the Team on all assignments and participates in all S.W.A.T. training.


Urban Search and Rescue Team

The Ontario Fire Department Urban Search and Technical Rescue Team was developed in March of 1989, in order to provide specialized rescue techniques beyond the realm of standard Firefighter training.  The USAR Team has the training, resources, and capabilities to perform: high angle rescues, low angle rescues, train crash rescues, confined space rescues, and heavy equipment extrication.

All 24 team members and unit R-138 are California O.E.S. (Office of Emergency Services) Type-1 Heavy Certified and can respond anywhere in the state of California upon request.
