摘要： 为了保障草甘膦生产企业的安全生产，降低或避免其生产过程中火灾爆炸类安全事故的发生，拟采用改进的道化学火灾爆炸危险指数评价法 (DOW法) 对其进行安全评价。针对现行通用DOW法中安全措施系数计算不够准确的问题，增加人员安全补偿系数，并将安全补偿划分为预防事件发生型和缓解后果型，再对危险工艺单元进行定量分析和计算，从而提高DOW法安全评价结果的准确性。将改进的DOW法应用于某草甘膦生产企业的安全评价，结果发现，改进后的DOW法在火灾爆炸危险指数 (Fire and Explosion Risk Index，F&EI) 与暴露面积数值的测定上更灵敏，能更准确地反映草甘膦企业火灾爆炸的安全评价结果。

Abstract: In order to ensure the safe production of glyphosate production enterprises and reduce or avoid the occurrence of fire and explosion accidents in the production process, the improved Dow Chemical Fire and explosion risk index evaluation method (Dow method) is proposed to carry out safety evaluation. In view of the inaccurate calculation of safety measure coefficient in the current general Dow method, the personnel safety compensation coefficient is added, and the safety compensation is divided into event prevention type and consequence mitigation type, and then the hazardous process units are quantitatively analyzed and calculated, so as to improve the accuracy of the safety evaluation results of Dow method. The improved Dow method is applied to the safety evaluation of a glyphosate production enterprise, and it is found that compared with the traditional Dow method, the improved fire and explosion risk index (F&EI) and exposure area are more sensitive and can more accurately reflect the fire and explosion safety evaluation results of glyphosate enterprises.

Key words: DOW method, safety evaluation, hazard level, safety measures
