水成膜泡沫液失效分析及整改措施

Failure analysis on AFFF liquid and rectification measures

分析了某大型油库泡沫站泡沫液失效的问题,找出了泡沫液失效的主要原因是止回阀关闭不严导致消防水反串进入泡沫液罐,提出并对止回阀更换为电动阀的整改措施。

Failure of AFFF liquid was analyzed.The reason of it was that the valve was not so tight that the fire fighting water was leaked into the tank.The measure was put forward to replace the check valve with the motor operated valve.
