摘　　要：目的对涉及风向频率的现行国家行业标准进行分析,以期为职业卫生评价工作者提供有益的参考。方法收集现行有效国家行业标准中涉及风向频率的规定条款,建立数据库进行比较分析,并对个别条款辅以问询调查。结果相对于“有害危险的”场所,“受保护的”场所一般应位于其全年最小频率风向的下风向。有22种风向被各标准采用,采用率最高的是全年最小频率风向,占条款总数的72.00%。针对中心化验室和变配电设施、变电所,不同标准对其相对位置的规定有差异。结论针对可能产生毒害气体、粉尘等职业危害场所,80%以上条款采用全年最小频率风向是合适的,但部分标准对同一种受保护场所的相对位置规定不一致,有待进一步调整。Objective To analyze the current national industry standards involving wind direction frequency,in order to provide useful reference for occupational health evaluation workers. Methods Collect the provisions of the current effective national industry standards that involve the frequency of the wind direction,establish a database for comparative analysis,and supplement the individual clauses with inquiry surveys. Results A “protected” location should generally be located in the downwind direction of its annual minimum frequency wind direction relative to “harmful and dangerous” locations. There are 22 wind directions adopted by various standards. The highest adoption rate was the annual minimum frequency wind direction,accounting for 72.00% of the total number of articles. For central laboratories and power distribution facilities and substations,different standards have different provisions for their relative positions. Conclusion For occupational hazards that may produce toxic gases,dust,etc.,it is appropriate to use the minimum frequency wind direction of the year for more than 80% of the articles. However,the relative position of some standards for the same protected site is inconsistent and needs further adjustment.
