• Officer Needs Help. This emergency call shall be broadcast when immediate aid is required by an officer. The officer requesting shall include the location, followed, if possible, by the unit identification and all other pertinent information. A specific unit shall be dispatched "Code Three" and other available units in the vicinity shall respond "Code Two." An "Officer Needs Help" call shall not be broadcast when "assistance" only is needed. The Department will provide assistance and respond to "Officer Needs Help" calls within the City when requested by the CHP. The senior officer of the agency requesting emergency assistance shall be in charge of the incident unless the incident involves a situation which is the responsibility of the other agency, in which case the senior officer of the responsible agency will be in charge.
  

• Firefighter Needs Help. This emergency call shall be broadcast when immediate police assistance is required because firefighters are being attacked, attack is imminent, or other emergency exists. A specific unit shall be dispatched "Code Three" and other available units in the vicinity shall  respond "Code Two."
  

• Officer Needs Assistance. This call shall be broadcast when additional aid is required by an officer. The officer requesting shall include the location, followed by the unit identification and all other pertinent information, including the reason for request. A specific unit shall be dispatched "Code Two" and other available units in the vicinity shall respond when practicable.

• Back up Unit Request. This call shall be broadcast when an additional unit is required by an officer. The officer requesting shall include the location, followed by the unit identification and all other pertinent information. Only the specific unit dispatched shall respond. The request shall be canceled when, prior to the arrival of the assigned back up unit, it is determined that an additional unit will not be needed.
  

• "Pursuit" Procedure. A unit announcing a "Pursuit" shall begin the message by stating that the unit is in "Pursuit" and giving the location, followed, if possible, by the unit identification, description of pursued vehicle, and/or suspects, direction taken, and reason for pursuit. The pursuing unit shall give frequent and comprehensive progress reports as conditions permit. Any unit having information regarding the "Pursuit" may transmit. Communications Division will broadcast advisory information concerning pursuits by the CHP within the City. Department personnel shall not become involved in CHP pursuits on the freeways unless for serious felonies committed within the City of Los Angeles.
  

•  Code One. When the control operator fails to receive an acknowledgment of a communication, a "Code One" shall be given. The unit to which a "Code One" is directed shall acknowledge immediately upon hearing a "Code One."
  

• Code Two. A radio call accompanied by a "Code Two" designation is an urgent call and shall be answered immediately. The red light and siren shall not be used, and all traffic laws shall be observed.

Note. Officers responding to a "Code Two" radio call shall only interrupt the Code Two call to perform police work of major importance (0/030).

Officers' Responsibilities. Officers who interrupt their response to a Code-Two call due to police work of major importance or other exigent circumstances shall immediately notify Communications Division. Officers who interrupt their response to a Code-Two call for more than a brief delay to evaluate the comparative urgency of an intervening incident shall also request Communications Division to reassign the call and shall immediately notify a concerned Department supervisor. No notification is required when a Code-Two call is interrupted at the direction of either Communications Division or a Department supervisor. Officers shall document the reason for the interruption with an appropriate log entry on their Daily Field Activities Report (DFAR), Form 15.52.0 or 15.52.1.

Supervisors' Responsibilities. Concerned supervisors shall ensure that each interrupted response which resulted in reassignment of a Code-Two call is evaluated for appropriateness. In making this evaluation, the concerned supervisor should consider monitoring the divisional radio frequency, reviewing relevant log entries, responding to the scene of the interruption, or other appropriate action.

• Code Three. A radio call accompanied by a "Code Three" designation is an emergency call. It shall be answered immediately, but in a manner which will enable the unit to reach the scene as quickly as possible with safety. Exemption from provisions of the Vehicle Code (Division 11) is granted only when officers sound a siren as reasonably necessary and the officers’ vehicle displays a lighted red lamp visible from the front.

Any call may justify a "Code Three" if any of the following elements are present:

• A serious public hazard.

• The preservation of life.

• A crime of violence in progress.

• The prevention of a crime of violence.

• An immediate pursuit.

• A unit at the scene requests another unit "Code Three."

The final decision for the use of "Code Three," other than in response to a directed radio call, shall be made by the vehicle operator.

An officer shall immediately broadcast his intention to proceed "Code Three" when the decision is based on other than a directed police radio call. The "Code Three" broadcast shall include the nature and location of the activity and, when known, the starting point, route of travel, and destination.

Exception: Whenever officers activate their Code Three equipment in conjunction with mobile field tactics at the scene of a riotous incident, a "Code Three" notification to Communications Division is not required.

Note: Officers traveling to the scene of a riotous incident in a mobile field force configuration with their Code Three equipment activated shall still notify Communications Division that they are traveling Code Three.

When the "Code Three" has been terminated, the officer shall notify Communications Division as soon as practicable.

When more than one unit is "Code Three" in the same general area, they shall be notified by Communications Division that other units are "Code Three" in the vicinity.

Radio units which are not assigned to the call and which are not at the scene shall return to their assigned patrol area when a "Code Four" is broadcast.
  

• Code Four Adam. When additional assistance is not needed at the scene of an "All Units," call but the suspect is still in the vicinity, a "Code Four Adam," followed by the location of the call, shall be broadcast. This should then be followed by a description of the suspect. Radio units which are not assigned to the call but which are on the way to the scene shall, when a "Code Four Adam" is broadcast, patrol or post themselves at strategic locations near the scene.
  

• Code Five. A unit intending to "stakeout" shall notify the control operator of the location and request a "Code Five." The control operator, upon receipt of the message, shall immediately broadcast that there is a "Code Five" at the particular location. All units shall avoid the vicinity except in an emergency or in response to a call.
  

• Clearing Code Five. When the need for a "Code Five" no longer exists, the originating unit, or the last unit to leave the scene, shall request the control operator to clear the "Code Five" at the particular location.
  

• Code Five Edward.  A "Code Five Edward" shall be used to notify Air Support Division (ASD) personnel of an explosive hazard to low-altitude aircraft.  All units shall avoid the vicinity except in an emergency or in a response to a call for service.

Officers’ Responsibilities. An officer determining that an explosive hazard exists to low-altitude aircraft shall immediately notify Communications Division of a "Code Five Edward" via telephone or radio.

Note: Radio or Mobil Digital Terminal (MDT) communications may detonate an explosive device. All radio or MDT communications should be made approximately one block (500 feet) away from the "Code Five Edward" location.

The officer shall inform Communications Division of the "Code Five Edward" location, and the area of the established perimeter (as measured in feet) around the bomb device/explosive hazard.

Note: If personnel from the Explosives Unit, Scientific Investigation Division, determine that the established perimeter is insufficient for the potential hazard rendered from a suspected explosive device, they shall immediately notify Communications Division of the expanded perimeter as measured in feet.

A "Code Five Edward" notification shall be made in addition to all the other Department requirements for investigations involving explosives (4/212.50), when the following circumstances exist:

• Incident involving an explosive device which is in an exposed (open air) area or will be moved to an exposed area;

• Incident where the Explosives Unit intends to "render-safe" any explosive item in an exposed area; and,

• Incidents involving any explosives (indoors or outdoors) where the explosion could result in blast pressures that may be hazardous to aircraft operations.

Supervisors’ Responsibilities. The concerned supervisor shall ensure that Communications Division is notified of any perimeter adjustment.  When the need for a "Code Five Edward" no longer exists, the concerned supervisor shall ensure that Communications Division is notified to clear the "Code Five Edward."

Communication Division - Responsibilities. Upon receiving notification of a "Code Five Edward," the Radio Telephone Operator (RTO) shall immediately broadcast the "Code Five Edward" notification and the location.

The Watch Commander, Communications Division, shall ensure that the Watch Commander, ASD, is notified of the "Code Five Edward" broadcast and any adjusted perimeter throughout the incident.

Watch Commander, ASD - Responsibilities. Upon notification of the "Code Five Edward" location, the Watch commander, ASD, shall ensure that deployed Department aircraft are notified of the "Code Five Edward" location and any adjusted perimeter throughout the incident.  The Watch Commander, ASD, shall further ensure that similar broadcasts are provided to media aircraft in the area.

Note:  Department pilots shall determine a safe altitude for any Department aircraft responding to a "Code Five Edward" location upon notification of any perimeter adjustment.
