The main container for storing foam liquid is mainly made of special steel,stainless steel or polyethylene plastic material.At the same time,the foam liquid storage tank needs to use solvent resistant paint to make anticorrosive treatment of the inner wall.And must pay attention to,water film foam liquid,anti alcohol foam liquid corrosion is bigger,have special requirements for anticorrosive coatings,storage should be given great importance.The actual storage should also be careful:foam tanks with foam extinguishing agents should be filled as far as possible and ensure that they are sealed.

　　Foam extinguishing agents generally can not be premixed.Once the water is mixed with water,the period of validity will be greatly reduced.Of course,some foam extinguishing agents are exceptions,such as water film forming foam extinguishing agent,which can be stored in the form of original liquid,and can also be stored in the form of mixed liquid.But this is only a small number of special cases.Other foam extinguishing agents are still stored in raw liquid,and even different types,different models or foam extinguishing agents produced by the same type and different manufacturers can not be mixed storage.

　　Pay attention to maintaining the environment of the storage site:specifically,keep the storage site ventilated and dry,avoid direct sunlight,and prevent the mixing of impurities and other substances.

　　Periodic inspection:the main purpose is to detect and remove those severely defoamed fire extinguishing agents,and identify and mark those spoiled but not serious foam extinguishing agents.
