Surveillance data suggest high rates of electrocutions and fatal falls among workers in electric utility companies, who may be exposed to electric current, heights, flammable agents, and frequent motor vehicle travel. To characterize the occurrence of fatal injuries among electric utility workers, we studied workers in five electric power companies in the United States. A cohort of 127,129 men hired between 1950 and 1986 was followed through 1988. Injuries at work were identified through manual review of death certificates. The occurrence of occupational injuries was analyzed with directly adjusted rates and Poisson regression. The overall rate of fatal occupational injuries was 13.20 per 100,000 person-years (n = 192), with 76% due to electric current, homicide, and falls from heights. Deaths were concentrated in a few groups with elevated injury rates, notably linemen (rate ratio (RR) 3.33), electricians (RR 2.79), and painters (RR 3.27). Occupations requiring daily work on elevations or frequent, direct contact with energized electrical equipment experienced markedly higher rates of fatal injury from falls and electrocutions with rate ratios of 21.8 (95% confidence interval (CI) 11.4-41.5) and 16.7 (95% CI 6.6-42.6), respectively, independent of worker age and seniority. Although fatal injury rates in this industry have declined in recent decades, significant numbers of deaths still occur. Based on the premise that all injuries are preventable, a need for continued vigilance and efforts at prevention is indicated.
监测数据显示,电力公司工人触电和致命坠落的发生率很高,他们可能会接触电流、高处作业、易燃物以及频繁的机动车出行。为了描述电力公司工人致命伤害的发生情况,我们对美国五家电力公司的工人进行了研究。对1950年至1986年间雇佣的127129名男性队列进行了追踪,直至1988年。通过人工查阅死亡证明来确定工作中的伤害情况。采用直接调整率和泊松回归分析职业伤害的发生情况。致命职业伤害的总体发生率为每10万人年13.20例(n = 192),其中76% 是由电流、凶杀和高处坠落导致的。死亡集中在少数伤害率较高的群体中,特别是线路工人(率比(RR)3.33)、电工(RR 2.79)和油漆工(RR 3.27)。需要每天在高处作业或频繁直接接触带电电气设备的职业,因坠落和触电导致的致命伤害发生率明显更高,率比分别为21.8(95% 置信区间(CI)11.4 - 41.5)和16.7(95% CI 6.6 - 42.6),与工人年龄和工龄无关。尽管该行业的致命伤害率在最近几十年有所下降,但仍有大量死亡事件发生。基于所有伤害都是可以预防的前提,表明需要持续保持警惕并努力进行预防。
