摘要 |
The fire fighting and hot surface cooling methods of this invention use a compos ition formed by combining a nonionic surfactant possessing a specific photoexcitable functional group with an arylpho sphate, also of photoexcitable nature, in a solvent medium of composition and content that allows for a convenient workable viscosit y and is resistant to effects of freezing. The ultimate water solution used for spraying to extinguish a fire or cool a surface contains from 2000 ppm of the surfactant nonylphenolethoxylate and 94 ppm of the arylphosphate, phenol-6-phosphate, to 3000 ppm surfactant and 141 ppm arylphosphate. A non-aqueous composition containing a mixture of different nonylphenolethoxylates to extingui sh lithium type fires is also described. The spray solution is applied to the fire until the desired result occurs.
