ABSTRACT:
A method for restraining a chemical discharge comprising (a) deploying a binding agent into a 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; and (b) contacting the hazardous material with the binding agent to form a composition comprising at least a portion of the hazardous material and the binding agent and having at least one property selected from a solid or semisolid state, a viscosity greater than the viscosity of the hazardous material at ambient conditions, a vapor pressure lower than the vapor pressure of the hazardous material at ambient conditions, and a surface tension greater that the surface tension of the hazardous material.
