CODE 3 DRIVING

Long Beach Fire Department Policy and Procedure

 

Rescue Units

 

3.10.7.4        Respond to Bravo and Charlie responses Code 3, unless otherwise noted by alarm office

 

 

 

Engine Companies:

2.1.3.1          Freeway Response:  Response ON the freeway shall normally be code 2.  Code 3 may be used at the discretion of the officer in charge of the apparatus.

 

2.1.1.11        All emergency response shall be driven in accordance with the State of California Motor Vehicle Code governing authorized emergency vehicles.  For clarification, refer to Departmental Driver Training Manual, Section 3 “Code 3 Driving”.

 

2.1.13.5        First-Alarm Assignments:  if the first on-scene unit reports “nothing showing” or something with similar intent, all other responding units shall go Code 2 and continue in until cancelled.  Caution should be exercised when changing from Code 3 to Code 2 to avoid unsafe effects on traffic.

 

2.1.1.3          Companies shall NOT use red lights or sirens when “moving up”.

 

 

Marine Safety Division:

3.69              Rescue Boats:  Code 3 shall be used for major medical aids, fires, boating accidents involving serious injury, vehicle in water with person inside, vessels going aground, sinking or in some immediate distress or people in the water due to capsizing and threatened with hypothermia.

                     approaching the beach endangering others.

 

                     Medical Emergencies:  All victims down; fractures or possible

                     fractures; all submersions or possible submersion victims; any    medical aid situation requiring additional medical supplies or     assistance.

 

                     Includes procedures for Emergency Driving, which covers

                     Code 3 driving on the beach and street.

 

 

Golden Rule:  Excessive speed with little regard for safety is never justified.

 

Legal Considerations

 

California Vehicle Code:

 

·        30:  Red Lights and Siren:  Should be restricted to authorized emergency vehicles engaged in police, fire, and lifesaving services.

 

·        17001:  Liability of a Public Entity:  A public entity is liable for death or injury to person or property proximately caused by a negligent or wrongful act or omission in the operation of any motor vehicle by an employee of the public entity acting within the scope of his employment.

 

·        17004:  Authorized Emergency Vehicles:  A public employee is not

      liable for civil damages on account of personal injury to or death             from the operation, in the line of duty, of an authorized emergency          vehicle ... when responding to but not upon returning from a fire             alarm or other emergency call.

 

·        21055:  Exemption of Authorized Emergency Vehicles:  Drivers of emergency vehicles are exempt from certain traffic laws as long as the vehicle is being driven Code 3 (siren as reasonably necessary and red lights) in response to an emergency call.

 

·        21056:  Effects of Exemption:  Privileges granted under Section 21055 do not relieve the driver from driving with due regard for the safety of all persons using the highway, nor protect from consequences of an arbitrary exercise of the privileges.

 

Conditions for Code 3 Responses

 

Code 3 is justified only when initially responding to an emergency call or transporting a patient with a life-threatening emergency such as:

 

·          Uncontrolled hemorrhage

 

·          Uncontrolled cardiovascular or respiratory status

 

·          Complicated impending childbirth

 

Warning Lights and Sirens

Vehicle Code Sections 25268 and 25269 restrict the use of warning lights to conditions of "extreme hazard" and "unusual traffic hazard".  Proper use is as follows:

·          Steady burning red light: shall be displayed when required by VC 21055 or when an extreme hazard exists. 

 

·          Flashing red light:  may be displayed only during extremely hazardous conditions, i.e., any incident or situation that requires traffic to stop or proceed only as directed, any incident that requires the roadway to be blocked, or other situations in which extreme hazards exists.

 

·          Flashing amber lights:  may be displayed only when an unusual traffic hazard exists.

 

 

 

Precautions:

·          Warning lights may be ineffective due to low sun or glare, due to confusion with traffic signals or neon lights, or the position of the lights may be out of visual range of the oncoming vehicles.

 

·          Sirens warn vehicles or pedestrians traveling in the same direction and ahead of the ambulance; lose effectiveness in warning vehicles approaching head on or traveling on converging roads.

 

·          Never assume the red lights and siren will clear the way through traffic or that the motorists will do what is expected.

 

 

Negotiating Intersections

Precautions:

·          Visibility is obstructed by buildings, landscaping, or other vehicles

 

·          Drivers misjudge traffic situations and clearance

 

·          Motorists don't hear or see the approaching ambulance

 

·          Two or more emergency vehicles often "meet" at intersections

 

·          Check for actual or potential hazards well in advance of the intersection

 

·          Look to left, then right, then left again before entering the intersection

 

·          Maintain safe following distance, especially if following another emergency vehicle.

Ambulance Backing

           Station a crew member outside to the left rear of the vehicle

 

           Check for pedestrians and obstacles

 

           Sound horn before backing

 

           Back slowly

 

           Check mirrors constantly

 

 

Parking At Scene

Factors to consider:

·          Presence of hazardous materials

 

·          Traffic flow and pattern

 

·          Access to victim(s)

 

·          Number of emergency vehicles

 

·          Parking Pattern: Engine in at angle, then ambulances or rescues park in front of engine

 

Warning Flares

·          Usually set out ahead of an incident

 

·          May be set in a straight line to serve as a warning to traffic or may be set in a pattern to route traffic from one lane to another or to completely halt traffic

 

·          After pattern is established, a single flare should be placed well in advance of pattern to serve as warning to traffic, particularly in areas where road visibility is poor

 

·          In fire hazard areas, a man should be in attendance of flares at all times
