I'd like to add another perspective to this discussion.. I believe that there are two potential problems with refrigerated storage of pyrophoric materials. First, as others have mentioned is the problem of condensation forming on the container and potential contact with the contents if it is used while still cold. Second, is that pyrophoric materials should be segregated from regular flammable and combustible liquids and solids. Pyrophoric materials are like oxidizers and explosives fuses in that regard. If you are going to refrigerate pyrophoric materials (and there is no fire safety reason for doing this), do not allow other flammable materials to be stored in the same fridge or cabinet.
