Falls from heights are a leading cause of mortality and morbidity in the construction industry, especially among inexperienced workers. We surveyed apprentice carpenters to identify individual and organizational factors associated with falls from heights.
We developed a 72-item survey on fall prevention with multiple domains including fall experience, fall-prevention knowledge, risk perceptions, confidence in ability to prevent falls, training experience, and perceptions of the safety climate and crew safety behaviors. We administered the questionnaire to apprentice carpenters in this cross-sectional study.
Of the 1025 respondents, 51% knew someone who had fallen from a height at work and 16% had personally fallen in the past year, with ladders accounting for most of the falls. Despite participation in school-based and on-the-job training, fall-prevention knowledge was poor. Ladders were perceived as low risk and ladder training was rare. Apprentices reported high levels of unsafe, fall-related behaviors on their work crews. Apprentices in residential construction were more likely to fall than those in commercial construction, as were apprentices working on crews with fewer senior carpenters to provide mentorship, and those reporting more unsafe behaviors among fellow workers.
Despite participation in a formal apprenticeship program, many apprentices work at heights without adequate preparation and subsequently experience falls. Apprenticeship programs can improve the timing and content of fall-prevention training. This study suggests that organizational changes in building practices, mentorship, and safety practices are also necessary to decrease worker falls from heights.
高处坠落是建筑行业导致死亡和发病的主要原因,尤其是在经验不足的工人中。我们调查了学徒木匠,以确定与高处坠落相关的个人和组织因素。
我们开发了一个包含多个领域的 72 项预防坠落调查,包括坠落经历、预防坠落知识、风险认知、预防坠落能力信心、培训经验以及安全氛围和机组安全行为的看法。我们在这项横断面研究中向学徒木匠发放了问卷。
在 1025 名受访者中,51%的人知道有人在工作时从高处坠落,16%的人在过去一年中曾亲自坠落,其中大部分坠落是由梯子造成的。尽管参加了学校和在职培训,但预防坠落的知识仍然很差。梯子被认为风险较低,很少进行梯子培训。学徒报告在他们的工作队伍中存在高度不安全的与坠落相关的行为。从事住宅建筑的学徒比从事商业建筑的学徒更容易坠落,与那些在没有资深木匠提供指导的人员较少的队伍中工作的学徒相比,以及与那些报告同事中有更多不安全行为的学徒相比。
尽管参加了正式的学徒计划,但许多学徒在高处工作时没有充分的准备,因此会经历坠落。学徒计划可以改善预防坠落培训的时间和内容。这项研究表明,建筑实践、指导和安全实践方面的组织变革也是减少工人从高处坠落的必要条件。
