硫酸锌制备过程产生氢气的风险评价

【摘要】 对H公司制备Ni(OH) 2 产品的原料ZnSO4 时产生的H2 进行了包括风险识别、后果计算、风险管理、风险分析等内容的风险评价。当对产生的H2 采取直排法时 ,危险性D =2 5 2 ,为高度危险 ,必须立即采取措施降低风险 ;当对产生的H2 采取引射方法时 ,危险性D=18,为轻微危险 ,是可接受水平。更多还原

【Abstract】 When H company produces ZnSO 4 that is raw materials of Ni(OH) 2, H 2 is let off. The article carries out risk assessment to H 2 including risk identification, consequence calculation, risk management, risk analysis. If H 2 is discharged directly, danger level is high (D=252), so measures must be taken to reduce risk. After the measure importing the air is taken, danger level is slight and acceptable (D=18).更多还原
