The impact of major transformations of a production process on age-related accident risks: a study of an iron-ore mine

This paper describes a study of whether accident risks were equally distributed across age categories among a population of mining workers whose work activities were suspected to be age-impaired. The impairment factors in focus are the transformation of production technology during the 80s and consequent changes in job content. It was hypothesized that the combined effect of these factors might lead accident risks, both non-specific (aggregated) and specific (by kind), to increase with age. Accident risk ratios (ARRs), however, proved to be higher for younger workers than older ones, in both the non-specific and the specific cases. However, two accident patterns (specific risks) also show relatively high ARRs among workers in their 40s (and even 30s), results that might be explained by particular exposures and/or age-related performance problems. The findings suggest that technological changes designed to increase productivity and reduce staffing levels more rapidly affect efficiency and productivity than they do accident occurrence, and that they penalize young workers in the first instance.
