Industrial accidents and safety have been the focus for much research. Some studies have shown that different environmental settings, such as factories or even plants within the same factory, have different accident rates. As for the causes of accidents, previous research has often reduced the causes of accidents to human error or inappropriate behaviour. Nevertheless, recent studies show that one aspect which is of critical importance in achieving an environment of the highest possible safety standard is that of attitudes and safety culture. According to these studies over half of all industrial accidents are attributable to attitudinal and organizational factors. The aim of our study was to examine whether there were consistent differences in accident rate between different departments within the same industrial plant, and whether the differences, if any, might be accounted for by differences in the environment. Furthermore, our aim was also to examine, in relation to environmental evaluations, the attitudinal environment of these different plants, and the relationship between workers' attitudes towards safety and accidents. First, accident patterns for all and lost time injuries for the last 5 years were examined in eight departments of a plant of a heavy process industry in Britain to see whether there were consistent differences in accident rate between departments. Then safety attitudes of the workers were examined and compared to see whether there were differences in attitudes between these departments as a result of different organizational and attitudinal culture. Finally the relationship between attitudes and accidents was examined by correlating mean attitudinal scores with accident rates across departments. The results showed that there were differences in accident rate between departments. This difference showed a high level of consistency over time for all accidents (an average correlation of r0.87), while lost time accident showed a much lower consistency over time (on average rO.52). Also different safety attitudes between groups of departments were observed in the study. Finally, a relatively strong relationship (r-O.76) was found between attitude scores and all injury rate which suggests that attitudes towards safety are clearly linked to accident causation.
