This paper deals with the relationship between improvement in producti
on technology and its influence on occupational accidents. Based on a
review of the most recent findings concerning technological change and
accidents, it proposes a new context of interpretation for a previous
article concerning mechanization and accidents in the logging industr
y. The results obtained then suggested that occupational safety could
benefit greatly from the mechanization of production activities. Herei
n, the focus is broadened to take also into account the influence of t
echnological alternatives other than mechanization, and this in the pr
ocess as well as in manufacturing industries. Following a review of re
cent findings, three questions are discussed: (1) convergence in resea
rch findings; (2) isolability of the effects of technological improvem
ents on accidents; (3) needs regarding orientations for further studie
s. It is finally stated that, despite the existence of some tendencies
, the relationship between technological innovation and accidents cann
ot be seen as either uniform or deterministic.
