日本化工的安全和防止事故

世界环境 1990年第1期 36-38页

作者： koichi nishikawa 柯金良 Managing Director Japan Chemical Industry Association

日本化工出口总值约20万亿日元,出口量占日本制造业总量的7.7％。化工雇员约30.2万人,企业5352个。1986年销售额约1200亿美元。日本是世界上三大化工中心之一,其他两个是美国(销售额1980亿美元)和欧洲共同体(销售额2270亿美元)。按排列... 详细信息

日本化工出口总值约20万亿日元,出口量占日本制造业总量的7.7％。化工雇员约30.2万人,企业5352个。1986年销售额约1200亿美元。日本是世界上三大化工中心之一,其他两个是美国(销售额1980亿美元)和欧洲共同体(销售额2270亿美元)。按排列次序,日本仅次于美国,居世界第二位。日本化工与美国及欧洲共同体没有精确的安全比较数据,但在过去五年中,日本没有发生过严重的石油化工厂或仓库爆炸及火灾事故,而近年来欧洲经济共同体却发生过两次这类事故。因此,按国际标准衡量,日本化工厂的安全已达较高水平。在七十年代初,日本曾经发生过一系列事故。
