Study of Biorhythms Effect on the Incidence of Lost Time Accidents and Their Severity: The Case of a Manufacturing Industry

摘要

The main objective of the present research is to study the biorhythms effects on the occurrence of the accidents resulting in lost time injuries and on the accidents severity. To carry out the present research, the reports of the occupational accidents in an Iranian industry assembling power plants turbines were studied and the required data collected. The biorhythms critical days of personnel caused accidents were then determined. To study the biorhythms effects on the occurrence of the accidents resulting in lost time injuries and on the accidents severity, Analysis Of Variance and Independent t-Test were applied respectively. The results show ed the biorhythm, regardless of its type, is a factor affecting the accidents lost days and their severity. It w as also demonstrated that physical and intellectual biorhythms affect the accidents lost days while emotional biorhythm has no effect on it. Moreover, only intellectual biorhythm affects the accidents severity. The present study concluded that the biorhythms theory, as an information system, plays a vital role in accidents prediction and prevention, and thus helps to reduce the excessive costs imposed on industries and on the countries' econo my
