Tlx> toxicity r-opoit on Pydrrul 150 indicates thit it io praotioally Innocuous when fed orally to rats since the anUaala survived single doses of 28.5 stood per kilobitsTM with loou of appetite and severe diarrhea ao ti only toxic effeote, Tho fluid apparently ie not absorbed throu^i the unbroken akin of rebbito since this epecioo survived dosos up to 9.5 grass per fcUograa of body weight. In rabbit skin and eye irritation studies, PyOraul 150 was no more cP In cased where worteaen have accidentally splashed or rubbed Pydrsul 150 Into the eyes, there has been severe pain out of proportion to the degree of irritation. Thin lu slnllar to the situation with noet synthetic fluids ss well as with any light petroleum oils. Ybysielans have used a 1 per cent pontoclalne eolution and ophthalmic cortisone acetate solution to relieve irritation. Zn acute vapor inhalation studies, rate survived a mix-hour exposure to an atmosphere saturated with Pydraul 150 vapors at roes t--psraturc. Baaed on the antral toxicity data and handling experience, our label lnoludee the following precautionary lnfexmtlcni CAUTION! CONTAINS CHLORINATED HTOOCARDONS Avoid prolonged breathing of vapors or Blots. Avoid contact with eyes or prolonged contact with akin. If akin contact occurs, rerave by washing with eeap and water, following eye oootaot, flush If oiDthTng*Eoooras soaked with fluid, launder before wearing again. DSW 018575 STLCOPCB4005119 fir. Richard B. Body 2 December 13, 19&2 Wo have not oarried out inhalation tests on this nateriol at higher than anblant temperatures. However, Z am oortaln that, based on this type of work with somewhat niiaiinT* ecnpounds, no hasard would exlBt fron such expoourec as would be necessary to turn off machines, atop oajor leaks, etc, X fool that at quite elevated teoperaturec, the char acter of the vapors would be irritating sufficiently that either respiratory protection would be used or the individual would not main in the atmosphere. We do not, however, have any HiC's available because thic figure is, ao you well know, for eight hour Inhalations, and not for acute episodes. The flash point for fydraul 150 is 425F., Cleveland Open Cup. The fire point is 4650y., Cleveland Open Cup. It ie my understanding that the flash and fire points at these tenperntures arc the results of breakdown of the fluid rather than being the flash and fire points for the vapors of tho fluid itself. Although wo do not have complete analytical data as to the composition of breakdown products, 2 would expect that a Major constituent would be carbon monoxide alone; with phonolloa, aldehydes, COg and water, depending on the of breakdown. If you have any further questions, please write ne directly. Very truly yours. ntfIn DSW 018576 *r*- STLCOPCB4005120
