Abstract:
1. A method for restraining a chemical discharge comprising: providing a receptacle containing a hazardous material in a liquid state; providing a module having a frangible surface that is in fluid communication with the interior of the receptacle, the module containing a binding agent and a propellant; deploying the binding agent into the receptacle containing a hazardous material in a liquid state upon the occurrence of at least one predetermined event that increases the risk of accidentally discharging or leaking the hazardous material from the receptacle, the deploying comprising breaking the frangible surface of the module; and contacting the hazardous material with the binding agent to form a composition comprising at least a portion of the hazardous material and at least a portion of the binding agent and having at least one property selected from the group consisting of a solid or semisolid state, a viscosity greater than the viscosity of the hazardous material, a vapor pressure lower than the vapor pressure of the hazardous material, and a surface tension greater than the surface tension of the hazardous material.
