Factors affecting individual injury experience among petroleum drilling workers.
To identify factors affecting the number of injuries experienced by petroleum drilling workers, we carried out a 44-month incidence density study on a cohort employed in January 1979 on mobile drilling units in the Gulf of Mexico. To control for job-related hazards, we computed a standardized ratio of observed to expected injuries for each worker based on his job history. The effect of personal and work history factors was then examined using analysis of variance. Age, rate of job changes, and rate of rig transfers had independent effects on injury rates. Length of service had little effect when age was controlled. The findings suggest that younger workers under stress such as job change may be more susceptible to injury than older workers, regardless of job. If so, targeted changes in procedures and environment which protect workers of all ages are important alternatives to reliance on supervision and experience in injury reduction.
