1. A package for enabling a user to mix a diluent with a hazardous material and then fill a syringe with the solution in such a way as to substantially prevent the hazardous material from entering the immediate atmospheric environment comprisinga vial including an open ended glass container, a hazardous material in said container, and an elastomeric stopper assembly disposed in sealing relation with the open end of said container for enabling the hazardous material to be sealingly contained therein, anda sealed bag enclosing the entire vial so as to provide exterior sealed containment for the vial in the event of unexpected failure of the container and elastomeric stopper assembly to sealingly contain said hazardous material,said hazardous material being in a form suitable to be readily dissolved by a diluent injected from a diluent containing syringe into said container through a needle extended through said elastomeric stopper assembly,said hazardous material being in an amount such that when dissolved in a proper amount of diluent within said container the solution has a volume substantially less than the sealed interior volume of said container,said bag being formed of plastic sheet material and having septum means therein operable to sealingly receive a needle therethrough and to provide a seal in response to the needle being withdrawn therefrom,said vial being sealed within said bag so as to form a space exteriorly of the vial which is controlled by the bag and into which access can be obtained by extending a needle of a syringe through said septum means,the plastic sheet material of said bag being sufficiently transparent as to enable a user to move a needle of a diluent containing syringe through (1) said septum means (2) an extent of said controlled space and (3) said elastomeric stopper assembly so that the syringe may be thereafter operated to inject the diluent into the container thus creating an increase in gas pressure within said container,said controlled space being operable to receive any hazardous material in the form of aerosol or droplets that may pass outwardly through said elastomeric stopper assembly as a result of the withdrawal of the syringe needle therefrom and the increased interior gas pressure created within said container as aforesaid,the controlled space being initially devoid of any hazardous material or diluent therefor and having a volume sufficient to enable the pressure therein to remain near atmospheric pressure in the event of the escape of gas pressure from said vial container as aforesaid so that there is substantially no tendency for gas therein to cause hazardous material which may have passed into said controlled space to escape to the atmosphere when the needle is removed from said septum means.
