||A program was conducted to evaluate the feasiblity of methods for plugging leaks in damaged chemical containers by application of suitable plastic barriers. Such a system would be valuable in helping to prevent water pollution from spilled hazardous chemicals. A large number of candidate sealants were evaluated in laboratory screening tests, including various urethane foams; polystyrene and polyvinyl acetate instant foams; filled and unfilled epoxy systems; and polysulfide, butyl, neoprene, and silicone rubber systems. The most promising results were obtained with the urethane foams. Additional evaluation and scaleup tests were made, including sealing of leaks of many different hazardous chemicals, application to leaks both under water and in air, and sealing of leaks in 55-gallon containers. The feasibility of this concept was demonstrated. As a consequence of the success already realized, it is probable that a practical and useful system, embodying this approach, can be developed.
