Acute work injuries among electric utility linemen.
This analysis presents differences in acute work injury rates among electric utility linemen who perform different work tasks. Incidence-density rate ratios were the primary measure of association and are based on the work injury and person-time data for each job title. Logistic regression was used to model race, age, job experience, total inservice, prior injury, and time from prior injury. Transmission linemen had the lower acute injury rate with 18.9 per 100 person-work-years (95% CI 16-20), distribution linemen had 27.8 per 100 person-work-years (95% CI 27-28), and apprentice linemen had 43.3 per 100 person-work-years (95% CI 41-45). Injuries to the trunk and sprains and strains are the predominant injury categories. Having a prior lost time injury increases the risk for subsequent lost time injury for transmission linemen (OR = 1.6, 95% CI = 1.0-2.7) and for distribution linemen (OR = 1.5, 95% CI = 1.3-1.6).
