This study addresses occupational safety in reinforced concrete construction, an area marked by high accident rates and significant worker injury risks. By focusing on activity-body part (A-BP) combinations, this research introduces a novel framework for quantifying injury risks across construction activities. Reinforced concrete construction tasks are categorized into ten specific activities within three major work types: rebar work, formwork, and concrete placement. These are further analyzed concerning six critical body parts frequently injured on-site: head/face, arm/shoulder, wrist/hand, torso, leg/pelvis, and foot/ankle. Using data from 2283 construction accident reports and expert surveys, the probability and severity of injuries for each A-BP element were calculated. Probability scores were derived from actual incident data, while severity scores were determined via expert evaluations, considering injury impact and the required recovery time. To ensure precision and comparability, scores were standardized across scales, enabling a final risk assessment for each A-BP. Results identified that wrist and hand injuries during rebar work activities, particularly cutting and shaping, exhibited the highest risk, underscoring the need for focused protective measures. This study contributes to construction safety management by providing detailed insights into injury risk based on activity-body part interactions, offering safety managers data-driven recommendations for tailored protective equipment, enhanced training, and preventive protocols. This research framework not only helps optimize safety interventions on conventional construction sites but also establishes a basis for future studies aimed at adapting these strategies to evolving construction methods.
本研究探讨钢筋混凝土建筑中的职业安全问题，这一领域事故率高，工人受伤风险大。通过关注活动-身体部位（A-BP）组合，本研究引入了一个新颖的框架，用于量化建筑活动中的受伤风险。钢筋混凝土建筑任务分为三大工作类型中的十种特定活动：钢筋作业、模板作业和混凝土浇筑。针对现场经常受伤的六个关键身体部位进一步分析：头部/面部、手臂/肩部、手腕/手部、躯干、腿部/骨盆和足部/脚踝。利用2283份建筑事故报告和专家调查的数据，计算了每个A-BP元素受伤的概率和严重程度。概率分数来自实际事故数据，而严重程度分数则通过专家评估确定，考虑到伤害影响和所需的恢复时间。为确保准确性和可比性，对分数进行跨尺度标准化，从而对每个A-BP进行最终风险评估。结果表明，钢筋作业活动中，尤其是切割和成型过程中的手腕和手部受伤风险最高，这突出了采取针对性防护措施的必要性。本研究通过基于活动-身体部位相互作用提供详细的受伤风险见解，为建筑安全管理做出了贡献，为安全管理人员提供了基于数据的建议，以定制防护设备、加强培训和制定预防方案。该研究框架不仅有助于优化传统建筑工地的安全干预措施，还为未来旨在使这些策略适应不断发展的施工方法的研究奠定了基础。
