(1) 首先应排除非静电的其他火源的可能性; (2) 根据静电产生的条件,估算可能的放电能量,如超过可燃物的点燃能量,有可能是静电点火源; (3) 可燃物的流速是否超过允许值; (4) 操作人员的操作情况及穿脱衣服情况; (5) 通过显微镜作微观形貌观察,是否存在类似“火山口”特征的高温熔融微坑,以确定静电放电的具体部位,鉴定事故的原因。
(1) First, the possibility of non-static other sources of ignition should be excluded; (2) Estimated the possible discharge energy according to the conditions of static electricity, such as the ignition energy of combustibles, there may be static ignition sources; (3) (4) operating conditions of the operator and wearing and undressing conditions; (5) microscopic observation of the microstructure to see if there are hot melt microchannels similar to the “crater” feature to determine the static charge Specific parts of the discharge, identify the cause of the accident.
