\Vhere Deaths Occur

The above chart representing a rough flow plan for processing timber into commercial lumber was drawn to locate pictorially the general operational region where were distributed the 179 fatal accidents which were studiecl. The accidents were so selected that there were used only those accidents having a reasonably direct relationship to the operational region of the industry indicated. The 179 fatal accidents were chosen from records in the birrisior, of Safety file covering Division Engineers' investigations over a period principally from 1945 through 1948.

The chart was set up principally to demonstrate an ef-

Iective technique of presenting statistical material. It does not propose to be an accurate study of all accidents covering a specific period of time nor does it propose to suggest a rate. It is believed, however, that in general the chart suggests a fairly reliable relative distribution of fatal .accidents in the opeiations indicated.

It should be borne in mind also, that a study covering a specific period of time of all lost time accidents in thc lumber industry would result in a much different percentage distribution than is suggested by this cliqtribution of fatal accidents.
