The Influence of “biorhythm” on the Incidence of Injuries among Agra Foundry Workers

The purpose of this study was to investigate the effects of three basic cyclic rhythms called biorhythms including a 23day physical cycle, a 28-day emotional cycle and a 33-day intellectual cycle on the incidence of accidents in Agra casting manufacturing units. For this purpose a sample of 462 accidents were randomly selected for the analysis. The statistical methods chi-square of significance level p<0.05and 95%CI were used to determine the significance of the study. Results of the study showed that Chi-square values were significant at p<0.05 in all the cases except in the case of serious accidents as response of results were mixed but the value of 95%CI is significant in all the cases as the values were much more than expected to occur on critical days purely by chance 20.4%. It was found, using alternative definition 4 of the critical days that 67.2% of accidents in case of total number of accidents examined and 72.8% of accidents in case of serious accidents were occurring on critical days for the various combinations of alternative critical days definition, which were higher than the other alternative definitions of critical days. Present work suggested that biorhythm theory acts as an information system and may be implemented in the industries in which chances of workers to get stuck with accidents are more. Relevance to industrySome industrial activities involve lifting and carrying heavy loads or working in dusty, fummy, and heated environment. Such tasks may lead to various types of accidents to the workers. This study investigated the effects of biorhythm on industrial accidents, so that the workers could be kept away from the hazardous tasks on critical days. The results may provide useful information for further study in the prevention of industrial accidents.
