DOWFROST HEAT TRANSFER FLUID PROPERTIES
Potential Health Effects
Eye Contact: May cause slight temporary eye irritation. Corneal injury is unlikely.
Skin Contact: Prolonged contact is essentially nonirritating to skin. Repeated contact may cause fl aking and softening of skin.
Skin Absorption: Prolonged skin contact is unlikely to result in absorption of harmful amounts.
Inhalation: At room temperature, exposure to vapor is minimal due to low volatility. Mist may cause irritation of upper respiratory tract (nose and throat).
Ingestion: Very low toxicity if swallowed. Harmful effects not anticipated from swallowing small amounts.
Effects of Repeated Exposure: In rare cases, repeated excessive exposure to propylene glycol may cause central nervous system effects.

First-aid measures
Eye Contact: Flush eyes thoroughly with water for several minutes. Remove contact lenses after the initial 1-2 minutes and continue fl ushing for several additional min-
utes. If effects occur, consult a physician, preferably an ophthalmologist.
Skin Contact: Wash skin with plenty of water.
Inhalation: Move person to fresh air; if effects occur, consult a physician.
Ingestion: No emergency medical treatment necessary.
Notes to Physician: No specifi c antidote. Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient.
Accidental Release Measures
Steps to be Taken if Material is Released or Spilled: Small spills: Absorb with materials such as: Cat litter. Sawdust. Vermiculite. Zorb-all®. Collect in suitable and prop-
erly labeled containers. Large spills: Dike area to contain spill. Recover spilled material if possible.
Handling and Storage
Handling
General Handling: No special precautions required. Keep container closed. Spills of these organic materials on hot fi brous insulations may lead to lowering of the autoig-
nition temperatures possibly resulting in spontaneous combustion.
Storage
Do not store in: Galvanized steel. Opened or unlabeled containers. Store in original unopened container.

Personal Protection
Eye/Face Protection: Use safety glasses.
Skin Protection: Wear clean, body-covering clothing.
Hand protection: Use gloves chemically resistant to this material when prolonged or frequently repeated contact could occur. Examples of preferred glove barrier materi-
als include: Butyl rubber. Natural rubber ("latex"). Neoprene. Nitrile/butadiene rubber ("nitrile" or "NBR").
Respiratory Protection: Respiratory protection should be worn when there is a potential to exceed the exposure limit requirements or guidelines. If there are no appli-
cable exposure limit requirements or guidelines, wear respiratory protection when adverse effects, such as respiratory irritation or discomfort have been experienced, or
where indicated by your risk assessment process.
