FEASIBILITY STUDY OF RESPONSE TECHNIQUES FOR DISCHARGES OF HAZARDOUS CHEMICALS THAT FLOAT ON WATER

An in depth evaluation was conducted of potential response techniques for ameliorating the vapor hazard from discharges of hazardous chemicals that float on water. Fifteen techniques were selected on the basis of their performance in similar situations, such as oil spills and hazardous chemical production or handling. Six of these techniques were judged to be feasible methods for achieving the objectives of this program. Vaporization rate reduction, the objective of Task I, could be achieved by using surfactant films, foams or sorbents. Vapor concentration reduction, the objective of Task II, could be achieved by encapsulation. Vapor flammability reduction, the objective of Task III, could be achieved by using foams and water aerosols. Techniques utilizing particulate cover, 'foamed-in-place' urethane layer, gels and cryogenic cooling were defined as having potential for successful utilization. All techniques were judged to need some further development or assessment. Recommendations for specific programs are presented. (Author)
