BACKGROUND Masons have a high rate of musculoskeletal disorders among construction workers and greater than all other industries. Viable solutions to musculoskeletal hazards have been identified by industry stakeholders, yet masons receive minimal ergonomics training. Apprentices, as the next generation of masons, need training and strategies to identify and speak up about ergonomic and safety issues on job sites. To fill this gap, our team developed the Safety Voice for Ergonomics (SAVE) training program. METHODS The interactive, 7-unit SAVE program was developed specifically for masonry brick and block apprentices. This innovative training contains detailed ergonomics lessons focusing on risk factors and solutions specific to this masonry craft. It also contains lessons that provide communication and problem solving strategies. Evaluation of SAVE employed a randomized control trial designed to assess the effectiveness of SAVE for apprentices over a six-month period. RESULTS Our findings demonstrated that compared to controls, SAVE trained apprentices used their safety voice more (P = .049) and had greater safety participation (P = .028). They adopted more ergonomic practices such as adjusting scaffolding (P = .016) and using better body postures (P = 042). Apprentices liked SAVE and indicated that it prompted them to change workplace safety behaviors. CONCLUSIONS SAVE is an effective program, providing needed ergonomic and safety communication training for workers as they begin their trade. The broad adoption of SAVE training by the masonry industry has the potential to empower apprentices, elevate the trade's safety culture, and ultimately reduce musculoskeletal disorders.

安全的人机工程学语音（SAVE）：评估砌体学徒培训计划。

背景技术泥瓦匠在建筑工人中具有很高的肌肉骨骼疾病发病率，并且比所有其他行业更大。行业利益相关者已经确定了解决肌肉骨骼疾病的可行解决方案，但是泥瓦匠接受的人体工程学培训最少。作为下一代泥瓦匠，学徒需要培训和策略，以识别和谈论工作现场的人体工程学和安全问题。为了填补这一空白，我们的团队制定了“人机工程学安全语音（SAVE）”培训计划。方法互动式7单元SAVE程序是专门为砖石砌块和砖砌学徒开发的。这项创新的培训包含详细的人体工程学课程，重点是针对该砌筑工艺的风险因素和解决方案。它还包含提供交流和解决问题策略的课程。对SAVE的评估采用了一项随机对照试验，旨在评估SAVE在六个月内对学徒的有效性。结果我们的研究结果表明，与对照组相比，SAVE受过训练的学徒使用他们的安全声音更多（P = .049）并且具有更大的安全参与度（P = .028）。他们采用了更符合人体工程学的做法，例如调整脚手架（P = .016）和使用更好的身体姿势（P = 042）。学徒喜欢SAVE，并指出它促使他们改变工作场所的安全行为。结论SAVE是一项有效的计划，可为工人开展贸易提供必要的人体工程学和安全沟通培训。砌体行业广泛采用SAVE培训，有可能增强学徒的能力，提升行业的安全文化，
