EMS Unit Ids
The history of EMS unit IDs is as follows.
The first number correspondence to the Battalion Area, which for the most part correspond to the Fire Department Battalion numbers.
The second number corresponds to the physical area the unit primarily responds to .
The Letter corresponds to the type of unit. A or alpha thru N-nora are Basic Life support units.
O-oscar thru Z-Zebra are paramedic Units.
The exception are the H-Henry and the Z-Zebra which are Haztac BLS and ALS units
The R-Rescue which are Rescue Paramedic Units.
The last numbers is the tour. 3 Tours for FDNY units, hospital units can have 3 tours or 2 depending on whether they are 8hr or 12hr units.
Staten Island is divided primarily into 3 Fire Battalion Areas the 21, 22 and 23 Battalions.
So 22H2 means its a Haztac BLS unit assigned to the 22 Battalion working the Day shift.
22Z1 means its a haztac Paramedic unit assigned to the 22 Battalion working the midnight shift
23R3 means its a Rescue Paramedic unit assigned to the 23 Battalion working the eve shift.
21A1 means its a BLS unit covering the 21 Battalion working the midnight shift.
Keep in mind that these units overlap each other. When needed they respond all over the place.
Special numbers are used for special events units, or extra units.
So you may hear a 65D2 unit which is a BLS unit , running extra or in lieu of another unit, covering Staten Island.
Staten Island Hospital runs 2 Paramedic Units and 3 BLS (EMT) Units 21W and 23W Paramedic units and 21A, 23B and 23J EMT units.
RUMC runs 2 Medic Trucks, 21X and 22X plus 21B, 21C, 22D and 22B EMT units. these employees are not part of the Fire Department and hired by their respective hospitals. Some are fulltimers some are part timers.
The Fire Department runs
2 Medic units 1 regular medic unit and 1 haztac unit from 1 station and 1 haztac EMT unit plus 3 regular BLS units covering the middle of the island
22Z, 22V, 23D, 22H, 22C
The Rossville station runs 23V, 23R 23H, 23A and 23C covering the south-west shore of Staten Island.
All Fire Department EMS ambulances are run by Fire Department EMTs or Paramedics which are fulltime city employees.
Some of these units do not run the midnight shift. Hope this helps.
