2 QUARRY ACCIDENTS IN THE UNITED STATES, 1939
enough to determine the trend of accident severity by applying to
the reported number of accidents the number of days of disability
per accident as shown by reports from a selected list of quarrying
companies, namely, those that participated in the National Safety
Competition conducted by the Bureau of Mines. Reports from the
plants enrolled in the competition for the past 3 years, 1937-39, showed
that the period of disability for temporary injuries averaged 34 days
per injury. Reports from the same companies showed that injuries
causing permanent partial disability averaged 1,248 days of disability
per injury when each accident of this class was weighted according
to the nature of disability and part of the body affected in accordance
with the standard accident table used for such injuries. Every death
or permanent total disability was assigned a uniform charge of 6,000
days of disability. When these factors were applied to the deaths,
permanent disabilities, and temporary injuries shown by the reports
covering all quarry and related operations in the United States during
1939, an accident-severity rate of 4.75 per thousand man-hours of
exposure was indicated. The corresponding rate for 1938, computed
in the same manner, was 6.57.
Pennsylvania led all other States in number of employees, with
more than twice as many as Ohio, which employed the second largest
number. Several of the 26 larger States had no fatal accidents during
the year; Michigan led these States with the largest number of man-
hours worked without a fatality within the State. Michigan also
had the lowest frequency rate for nonfatal injuries. (See tables 1 to 3.)
