February 16, 1966 Pi|i 2 About 15 yaara ago wa bad ratbar extensive teata run at Kettering Laboratories at the university or CineInnatl where a Fydraul fluid uaa apreyed on natal heated to 1050F and 1250F. the vaporised fluid and deeenpoeltlon products were discharged into suitable aniaal exposure ohanbera. Siwllar experiaants were run with a trloresyl phosphate hydraulie fluid and a petroleun based fluid. The general ooneluaion reached was that there was little difference, fron a praatieal standpoint, in the tonicity of the three products as Canonstrated in the experiaants. Zf a phosphate ester fluid or Fydraul is sprayed into olten aetal as a result of the rupture of a hydraulie line on a dleeaating aaehlne, a oloud of acrid vapor and awoke will develop, this will consist principally of aoot, CO, COe, water, aldehydes and cresals. In the ease of Fydraul, there will he in addition, hydrooblorie acid in the awoke duo to the dseaanosltlaa of the chlorinated eoapound. This way wake the aloud" aowaahat wore asrid or Irritating but does net significantly increase the toxicity. Where the fydreuls have been involved in such accidents, there have not been cases ahem anpleyees could not eafely shut down eqiilanant and leave the area. Aa with evj-t~ gr phosphate based fluid, it night or night not be necessary te wear respiratory protastloa to re-enter the area until it eould be ventilated. This would depend, of ooureo, on the mount of fluid that was apreyed er leaked ante the nolten natal or hot ourfaoe. our label roooanondo avoidance or repeated and prelonged akin contact.
