Objectives-Trends in the rates of total injuries and fatal accidents in the
different sectors of Italian industries were explored during the period 19
51-98. Causes and dynamics of injury were also studied for setting prioriti
es for improving safety standards.
Methods-Data on occupational injuries from the National Organisation for La
bour Injury Insurance were combined with data from the State Statistics Ins
titute to highlight the interaction between the injury frequency index tren
d and the production cycle-that is, the evolution of industrial production
throughout the years. Multiple regression with log transformed rates was ad
opted to model the trends of occupational fatalities for each industrial gr
oup.
Results-The ratios between the linked indices of injury frequency and indus
trial production showed a good correlation over the whole period. A general
decline in injuries was found across all sectors, with values ranging from
79.86% in the energy group to 23.32% in the textile group. In analysing fa
talities, the trend seemed to be more clearly decreasing than the trend of
total injuries, including temporary and permanent disabilities; the fatalit
ies showed an exponential decrease according to multiple regression, with a
n annual decline equal to 4.42%.
Conclusions-The overall probability of industrial fatal accidents in Italy
tended to decrease exponentially by year. The most effective actions in pre
venting injuries were directed towards fatal accidents. By analysing the ra
tes of fatal accident in the different sectors, appropriate targets and pri
orities for increased strategies to prevent injuries can be suggested. The
analysis of the dynamics and the material causes of injuries showed that st
ill more consideration should be given to human and organisational factors.
