Abstract |
The hypergolic rocket fuels, hydrazine and nitrogen tetroxide, are volatile hazardous materials of special interest to the Air Force. Through monitoring of ongoing Environmental Protection Agency programs, the Air Force has maintained cognizance of the developing state of the art in spill control. This Air Force supplement to the basic EPA program was a preliminary evaluation of the potential of cooling and foam covers to mitigate the vapor hazard from hydrazine and nitrogen tetroxide. Coolants exhibited some control over vapor release from the hypergolic fuels. Liquid nitrogen was the most effective material. Logistics were deemed a major disadvantage for the anticipated spill scenarios. Foams using commercial agents were beneficial with hydrazine but were not effective against nitrogen tetroxide. Modified foam systems incorporating acrylic resins were more effective. They were able to maintain hydrazine concentrations at or below 0.5 ppm. Some control was also exhibited with nitrogen tetroxide, but there was intermittent vapor release through the foam. Based upon the work of this program, the acrylic foams offer a promising approach to the control of the vapor hazard from hydrazine and nitrogen tetroxide. |
