Warehouse storing ethyl acetate and acrylic polymer

I need to design foam sprinkler system for protection of warehouse storing both ethyl acetate and acrylic polymer.

As per my research - ethyl acetate (flashpoint = -3 degree Celsius) needs Alcohol resistant Aqueous Film Forming Foam

whereas for acrylic polymer (flashpoint = > 250 degrees Celsius) needs Aqueous Film Forming Foam.

Since flash point of ethyl acetate is much lower than acrylic polymer - I believe the best way to protect such a warehouse is by using AR AFFF foam.

6.5lpm/me should be the design density, 3% AR AFFF foam, to be used for 10 mins.


Any inputs on the above would be of much help!
