SAFETY ALERT 安全警示 Site企业名称: 蓝星化 有限责任公司 Bluestar Chemical Co. LTD Incident resulted in事故导致: 丧失劳动时间Lost Time Description: 事故描述: 2010年 8月6日 10时， TDI车间污水处理岗位发现硫酸转子流量计损坏。操作 A先生、B先生进行拆除 更换处理 作。他们放尽导淋阀排完残余硫酸后，拆流量计上端法兰时，法兰处喷出硫酸造成二人烧伤。由 于法兰垫片是采用橡胶板制作，通径较小，长时间使用垫片膨胀将通径堵塞，在排放残料时流量计上部硫酸 流下不来，至使管道内存有物料，在拆除螺栓后移动流量计时硫酸喷出，造成事故的发生。二人被送医院治 疗，A先生留院继续治疗，B先生医疗处理后回家休养。 August 6 th about 10 am, sewage treatment’s operators of TDI workshop found the H 2 SO 4 rotor meter was damaged. The operators, Mr. A and Mr. B brought their tools to replace the instrument. The operators opened drain valve and released residual material. When they dismantled rotor meter’s up flange, the H 2 SO 4 ejected, which contribute to two operators burned. The block of rotor meter on the flange is the cause of incident. The flange gasket , which has smaller diameter hole is made of rubble. For a long time in H 2 SO 4 the gasket expanded, blocking material flowing down. After removal of the bolts of the meter the material ejected. Two employees were sent to hospital. Mr. A was advised to stay in hospital to continue treatment, while Mr. B went home to rest. Contributing Factors促成因素: 1. 考�不全面，底部�淋�打开放�硫酸，但未考�流量�上部管道有堵塞促成事故的�生。 Considering incomplete. Although they opened drain valve to release residual material, they didn’t consider the block of top pipeline , which lead to incident. 2. 未配戴防护用品（防护罩、护目镜） Not wearing protective equipment (protective mask, goggles).

Root Causes根本原因: 1. 作�前未�行危���； No hazard identification before operation (SWR)； 2. 未配戴防护用品（防护罩、护目镜） Not wearing protective equipment (protective mask, goggles). Corrective Actions采取的措施: 1. 加强操作 的安全培训，特别是PPE的培训。 To strengthen the safety training, especially the PPE training. 2. 硫酸、双氧水管线法兰不准用橡胶垫，改用耐酸垫片. For rubber gasket is not allowed to use in the H 2 SO 4 and Hydrogen peroxide substituting for acid-proof gasket.
