This study assessed the occupational health and safety risk-level of common building construction trades in Nigeria. It also identified the sources, frequency and magnitude of risks inherent in the activities of various building construction trades. Being site-based survey research, it made use of a structured questionnaire administered to the selected building construction workers of different trades in Anambra State, Nigeria. The collected data were subjected to quantitative risk analysis using mean value method and risk prioritisation number. The study found that masonry, carpentry (including formwork and roofing), and iron bending and steel fixing are common building trades associated with high risks; whereas electrical fitting and installation, painting, tiling, and plumbing are medium risk building trades. It also found that the rate of occurrence and magnitude of impact of different safety risk factors differ across the building trades, which could be attributed to the differences in activities and modes of operation in different building trades. On this premise, the study suggested a multi-risk management and control approach for construction managers on building construction sites since the frequency of risk occurrence and the magnitude of risk severity differ across trades. It further called for institutional and legislative re-strengthening of extant labour laws in Nigeria.

尼日利亚建筑行业的职业健康和安全风险水平

这项研究评估了尼日利亚普通建筑施工行业的职业健康和安全风险水平。它还确定了各种建筑行业活动中固有的风险的来源，频率和严重性。作为基于现场的调查研究，它使用了结构化的问卷，该问卷针对尼日利亚阿南布拉州不同行业的选定建筑施工工人进行管理。使用平均值方法和风险优先级数对收集的数据进行定量风险分析。研究发现，砖石，木工（包括模板和屋面）以及铁弯曲和钢固定是与高风险相关的常见建筑行业。电气安装和安装，喷涂，平铺和管道工程是中等风险的建筑行业。研究还发现，不同安全风险因素的发生率和影响程度在整个建筑行业中是不同的，这可以归因于不同建筑行业中活动和运营方式的差异。在此前提下，研究建议了针对建筑施工现场的施工经理的多风险管理和控制方法，因为风险发生的频率和风险严重性的大小在各个行业中都不同。它还呼吁在体制上和立法上加强尼日利亚现行的劳工法。该研究为建筑施工现场的建筑经理建议了一种多风险管理和控制方法，因为风险发生的频率和风险严重性的程度在各个行业中是不同的。它还呼吁在体制上和立法上加强尼日利亚现行的劳工法。这项研究提出了针对建筑施工现场的施工经理的多风险管理和控制方法，因为风险发生的频率和风险严重性的程度在各个行业中是不同的。它还呼吁在体制上和立法上加强尼日利亚现行的劳工法。
