THERMIMOL FR-IjO-TENP Toxicity and Safa Handling Information
On the basic of animal toxicity studies with other Therminol fluids, Therminol FR-LO-TEMP may ba considered moderately toxic from tha standpoint of accidantal masalva akin exposure and only slightly toxic if accidantally Ingested. Single expoauras to high concantratlona of vapora (whan haatad aufflclantly to volatlllxe) or high conoantrafelona of decomposition products (if tha fluid la accldantally dlaohargad Into tha flra chambar) should not ba carious hazards bacauoa tha Irritating charactar of such concantratlona preclude voluntary oxposura.
Ropaatad or prolongad akin axposura shouLd be avoldad slnca tha fluid uctc 00 a aolvant for fata and oils of the skin. Removal of these natural, protective barriers can lead to drying and chapping such as occurs with exposures to paint thlnnere. Mora Important, Therminol FR-LO-TEMF may be absorbed If tt Is allowed to remain on the unbroken skin. For these reasons, we recommend that tha skin be washed with soap and water If there is contact. A skin bum resulting from accidental contact with hot fluid should be treated In the normal manner for any thermal bum due to hot oils.
Because of its low vapor pressure, there Is no significant vapor inhalot in hazard when the fluid la at room temperature. For oxample, there la no vapor exposure problem while trans ferring the Thermlnolo from shipping containers to tha heat transfer system. On the other hand, the vapora emitted whan the fluid La heated to elevated temperatures are Injurious on prolonged exposure. It is erne1mated that the "threshold limit

In heat transfer Installations, tho fluid must be used In a closed aystorn free from leaks with the expansion tank vented to the outdoors. Accordingly, there should te little or no opportunity for workers to cone In contact vrith vapors.
