Portable ladders incidents remain a major cause of falls from heights. This study reported field observations of environments, work conditions and safety behaviour involving portable ladders and their correlations with self-reported safety performance. Seventy-five professional installers of a company in the cable and other pay TV industry were observed for 320 ladder usages at their worksites. The participants also filled out a questionnaire to measure self-reported safety performance. Proper setup on slippery surfaces, correct method for ladder inclination setup and ladder secured at the bottom had the lowest compliance with best practices and training guidelines. The observation compliance score was found to have significant correlation with straight ladder inclined angle (Pearson's r = 0.23, p < 0.0002) and employees' self-reported safety participation (r = 0.29, p < 0.01). The results provide a broad perspective on employees' safety compliance and identify areas for improving safety behaviours. Practitioner Summary: A checklist was used while observing professional installers of a cable company for portable ladder usage at their worksites. Items that had the lowest compliance with best practices and training guidelines were identified. The results provide a broad perspective on employees' safety compliance and identify areas for improving safety behaviours.
便携式梯子事故仍然是高处坠落的主要原因。本研究报告了对涉及便携式梯子的环境、工作条件和安全行为的现场观察，以及它们与自我报告的安全绩效之间的相关性。对一家有线电视及其他付费电视行业公司的75名专业安装人员在其工作现场的320次梯子使用情况进行了观察。参与者还填写了一份问卷，以衡量自我报告的安全绩效。在光滑表面上正确设置、正确的梯子倾斜设置方法以及梯子底部固定方面，与最佳实践和培训指南的合规率最低。观察到的合规分数与直梯倾斜角度（皮尔逊相关系数r = 0.23，p < 0.0002）和员工自我报告的安全参与度（r = 0.29，p < 0.01）有显著相关性。研究结果为员工的安全合规情况提供了广泛的视角，并确定了改善安全行为的领域。从业者总结：在观察一家有线电视公司的专业安装人员在其工作现场使用便携式梯子时使用了一份检查表。确定了与最佳实践和培训指南合规率最低的项目。研究结果为员工的安全合规情况提供了广泛的视角，并确定了改善安全行为的领域。
