The Assistant Chief for Operations manages and coordinates all areas of fire suppression; emergency medical services; airport protection; and specialty services such as air rescue, marine services, hazardous materials mitigation, the Motorcycle Emergency Response Team (MERT), Venom Response Team, ocean rescue, technical rescue, and urban search and rescue.

• Emergency Medical Services (EMS)
  The EMS Division provides medical direction for 50 Advanced Life Support (ALS) transport units, 47 ALS non-transport units, 17 Basic Life Support (BLS) non-transport units, and 3 ALS air-transport helicopters. These units are staffed by 1,249 paramedics and 656 Emergency Medical Technicians (EMTs). The total number of alarms during calendar year 2006 was 216,656, of which 76 percent were EMS-related.
• Operations North
  The North District provides state-of-the-art fire and rescue services to a dynamic region comprised of the unincorporated areas of northern Miami-Dade County and 20 individual municipalities. This response territory spans from the beaches on the east coast to areas beyond the Urban Development Boundary (UDB) in the west, and from the Miami-Dade/Broward County Line to Miami International Airport in the south. It is densely populated, primarily by our county's eldest residents. Fifty-one emergency units staffed by approximately 600 firefighter/paramedics and firefighter/EMTs respond from 27 fire stations to provide fire suppression, emergency medical services, advanced technical rescue and hazardous materials response to the residents and visitors of northern Miami-Dade County. 
• Operations South
  The South District provides state-of-the-art fire and rescue services to a rapidly growing region comprised mainly of the unincorporated areas of Miami-Dade County and 10 individual municipalities. This response territory spans from Biscayne Bay on the east to areas beyond the UDB in the west, and from the City of Doral in the north to the Miami-Dade/Monroe County Line in the south. The South District encompasses most of the county's rural/agricultural areas. Fifty-eight emergency units staffed by approximately 510 firefighter/EMTs and paramedics respond from 27 fire stations and provide fire suppression, emergency medical services, advanced technical rescue and hazardous materials response to the residents and visitors of southern Miami-Dade County. With the explosive growth and expansion being experienced in south Miami-Dade County, this division will no doubt continue to be among the fastest-growing areas in Miami-Dade County, and is expected to add 11 new fire stations and more than 20 new units in the future.
• Special Operations
  The Special Operations Division provides specialized assistance in the areas of air rescue, marine operations, dive rescue, ocean rescue, hazardous materials response, technical rescue, Venom Response Bureau, the Motorcycle Emergency Response Team (MERT), and urban search and rescue. These areas assist in mitigating technical emergencies and effecting rescues beyond the scope of standard field units.
• Airport Fire Rescue
  The Airport Fire Rescue Division has the responsibility of providing and coordinating all Aircraft Rescue and Fire Fighting (ARFF) protection activities at all airports in Greater Miami-Dade County, including Miami International Airport (MIA) and Opa-Locka Executive Airport. The division also provides inspection activities at MIA and the General Aviation Airport (GAA) systems, including Kendall-Tamiami Executive Airport, Homestead General Aviation Airport, and TNT (Dade-Collier) Airport, including Airport Rescue Firefighting (ARFF) services. The division is also responsible for mitigation of structural fires, medical emergencies, fuel spills, terrorism, hazardous materials, biochemical threats, radiological exposures and natural disasters, as well as fire inspections and code compliance review at our airports.
