摘　　要：针对PSA爆炸危险区域设计出现的专业职责不清晰、区域等级划分不合理等问题,通过对国内标准定义较为模糊概念的解读,结合国外IEC、API标准,提出较为合理的划分方法。最后,结合自身经验,梳理并总结了国外项目的常见问题及解决办法。Aiming at the problems of unclear professional responsibilities and unreasonable division of regional grades in the design of PSA explosion hazardous areas,through the interpretation of the relatively vague concepts of domestic standards,combined with foreign IEC and API standards,a more reasonable division method is proposed.Finally,combined with my own experience,sort out and summarize common problems and solutions of foreign projects.

关 键 词：危险区域划分 IEC API 国外
