Occupational accidents suffered by workers in Spain when using ladders were analyzed over a six year period from 2003-2008, during which the total of notified ladder-related accidents amounted to 21,725.
Different accident-related factors were identified for the purpose of developing a pattern of those factors that had the greatest influence on the seriousness and the fatality of such accidents. Thus, a series of variables were examined such as age and length of service of the injured worker, firm size, the work sector, the injury suffered, and the part of the body that was injured. Since falls is the most frequent and most serious of ladder related occupational accidents, a special analysis of falls was performed.
The findings showed that the seriousness of ladder-related accidents increased with the age of the injured worker. Likewise, accidents at places other than the usual workplace were more serious and registered higher fatalities than those that occurred at the usual place of work.
The analysis of falls from ladders established that accidents in smaller-sized firms were of greater seriousness and involved more fatalities than those in larger-sized firms. The investigation also underlined the need for stricter compliance with preliminary safety assessments when working with ladders.
对 2003 年至 2008 年期间西班牙工人在使用梯子时发生的职业事故进行了为期六年的分析，在此期间，报告的与梯子相关的事故总数达到 21725 起。
为了确定对事故严重程度和致死率影响最大的因素模式，确定了不同与事故相关的因素。因此，检查了一系列变量，如受伤工人的年龄和工龄、公司规模、工作部门、受伤情况以及受伤的身体部位。由于与梯子相关的坠落事故是最常见和最严重的，因此对坠落事故进行了专门分析。
研究结果表明，梯子相关事故的严重程度随着受伤工人年龄的增长而增加。同样，在非通常工作场所发生的事故比在通常工作场所发生的事故更严重，且死亡率更高。
对从梯子上坠落的事故分析表明，规模较小的公司发生的事故更严重，且死亡率更高，而规模较大的公司发生的事故则较轻。调查还强调了在使用梯子时需要更严格地遵守初步安全评估。
