           This section is provided to permit the classification of environmental
          events, circumstances and conditions as the cause of injury, poisoning and
          other adverse effects. Where a code from this section is applicable, it is
          intended that it shall be used in addition to a code from one of the main
          chapters of the International Classification of Diseases, Injuries and Causes
          of Death, indicating the nature of the condition. Most often, the nature of
          the condition will be classifiable to Chapter XVII, Injuries, Poisoning and
          Violence, and for the classification of the underlying cause of death these
          will always require an "E" code in addition. Causes of death should
          preferably be tabulated according to both the Chapter XVII and the "E" codes,
          but if only one code is tabulated then the "E" code should be used in
          preference to the Chapter XVII code. Certain other conditions which may be
          stated to be due to external causes are classified in Chapters I to XVI of
          ICD, and for these the "E" code classification should be used as an
          additional code for multiple-condition analysis only.
           Machinery accidents [other than connected with transport] are classifiable
          to category E919, in which the fourth digit allows a broad classification of
          the type of machinery involved. If a more detailed classification of type of
          machinery is required, it is suggested that the "Classification of Industrial
          Accidents according to Agency," prepared by the International Labor Office, be
          used in addition.
           Categories for "late effects" of accidents and other external causes are
          to be found at E929, E959, E969, E977, E989, and E999.
          Definitions and examples related to transport accidents
          (a) A transport accident (E800-E848) is any accident involving a device
          designed primarily for, or being used at the time primarily for, conveying
          persons or goods from one place to another.
          Includes: accidents involving:
           aircraft and spacecraft (E840-E848)
           watercraft (E830-E838)
           motor vehicle (E810-E825)
           railway (E800-E807)
           other road vehicles (E826-E829)
          In classifying accidents which involve more than one kind of transport, the
          above order of precedence of transport accidents should be used.
          Accidents involving agricultural and construction machines, such as tractors,
          cranes and bulldozers, are regarded as transport accidents only when these
          vehicles are under their own power on a highway [otherwise the vehicles are
          regarded as machinery]. Vehicles which can travel on land or water, such as
          hovercraft and other amphibious vehicles, are regarded as watercraft when on
          the water, as motor vehicles when on the highway, and as off-road motor
          vehicles when on land, but off the highway.
          Excludes: accidents:
           in sports which involve the use of transport but where the
           transport vehicle itself is not involved in the
           involving vehicles which are part of industrial equipment
           used entirely on industrial premises
           occurring during transportation but unrelated to the hazards
           associated with the means of transportation [e.g.,
           injuries received in a fight on board ship; transport
           vehicle involved in a cataclysm such as an earthquake]
           to persons engaged in the maintenance or repair of transport
           equipment or vehicle not in motion, unless injured by
           another vehicle in motion
          (b) A railway accident is a transport accident involving a railway train or
          other railway vehicle operated on rails, whether in motion or not.

          (e) A motor vehicle accident is a transport accident involving a motor
          vehicle. It is defined as a motor vehicle traffic accident or as a motor
          vehicle nontraffic accident according to whether the accident occurs on a
          public highway or elsewhere.
          Excludes: injury or damage due to cataclysm
           injury or damage while a motor vehicle, not under its own power,
           is being loaded on, or unloaded from, another conveyance
          (f) A motor vehicle traffic accident is any motor vehicle accident occurring
          on a public highway [i.e., originating, terminating or involving vehicle
          partially on the highway]. A motor vehicle accident is assumed to have
          occurred on the highway unless another place is specified, except in the case
          of accidents involving only off-road motor vehicles, which are classified as
          nontraffic accidents unless the contrary is stated.
          (g) A motor vehicle nontraffic accident is any motor vehicle accident which
          occurs entirely in any place other than a public highway.
          (h) A public highway [trafficway] or street is the entire width between
          property lines [or other boundary lines] of every way or place, of which any
          part is open to the use of the public for purposes of vehicular traffic as a
          matter of right or custom. A roadway is that part of the public highway
