1987年2月23日,龙头锰矿电解金属锰车问发生一起硫酸罐爆炸事故,使2人面部被浓硫酸烧伤,其中1人骨折,直接经济损失800多元,间接经济损失上千元.原来,该容积为28立方米的浓硫酸罐,多年未曾使用,近因恢复生产的需要,矿某负责人要求安全科立即进行试压检验,而安全科在不具备检测条件和没有防爆措施的情况下,竞违反压力容器检验规范,组织人员采用压气机进行试压检验,而且在加压过程中令修理工爬到酸罐上装照明灯。当加压至2.2kg/cm~2时发生了这一爆炸事故。
February 23, 1987, the leading manganese metal mine manganese car asked a sulfuric acid tank explosion occurred, so that 2 people were concentrated sulfuric acid burns, one fracture, the direct economic losses of 800 yuan, the indirect economic losses of a thousand dollars. It turned out that, The volume of 28 cubic meters of concentrated sulfuric acid tank, unused for many years, due to the need to resume production, mine head asked the Security Section immediately pressure test, and Security Section in the absence of detection conditions and no explosion-proof measures , Competing against the anti-pressure vessel inspection norms, organizational staff using the compressor for pressure test, but also in the pressurization process so that repairmen climbed acid cans on the lighting. This explosion occurred when pressurized to 2.2 kg / cm ~ 2.
