Description:
This program has been conducted to evaluate commercially available water base foams for mitigating the vapors from hazardous chemical spills. Foam systems were evaluated in the laboratory to define those foam properties which are important in mitigating hazardous vapors. Larger scale tests were then conducted in a 3 m x 3 m pan. Polar and nonpolar liquids and liquefied gases were used as test materials. Protein, fluoroprotein, alcohol and aqueous film forming foams were tested at low expansion ratios and surfactant foam agents at low, medium and high expansion ratios. The chemicals tested were acetone, n-butyl acetate, di-ethyl ether, n-octane, triethylamine, benzene, toluene, ethyl benzene, cyclohexane, propane, ethylene, butadience, ammonia, chlorine, ethylene oxide, hydrogen fluoride and sulfur trioxide.
