Potential health effects

Eye Contact: Contact with the eyes during product use is not expected to result in significant irritation. Skin Contact: Contact with the skin during product use is not expected to result in significant irritation. Inhalation: Vapors from heated material may cause irritation of the respiratory system. Signs/symptoms may include cough, sneezing, nasal discharge, headache. hoarseness, and nose and throat pain. If them1al decomposition occur.;: May be harmful if inhaled. Ingestion: No health efTects are expected. :'J.3 POTENTL<\L ENVIRONMENTAL EFFECTS A 3M Product Environmental Data Sheet (PED) is available. This substance has chemical moieties that are resistant to biodegradation and is likely to only undergo partial biodegradation in the environment. The high potential of this substance to move from water to the atmosphere means its potential to bioconcentrate is likely to disappear rapidly from aerobic environments. Take precautions to prevent direct release of this substance to the environment. AQUATIC TOXICITY: Testing results indicate that this product has insignificant toxicity to aquatic organisms at its saturation point Lowest LC50,EC50, IC50 > substance water solubility). (June 1997) Fathead Minnow (Pimephales promelas) 96-hr LC50 >750 mg/L NOTE: This data re flects the CA method which was used to satisfy the California (CA) Title 22 Hazard Evaluation Bioassay. This substance is highly volatile and has a high Henry's Law constant and is thus expected to move rapidly through vaporization from solution in an aquatic compartment or from a soil surface in a terrestrial compartment to the atmosphere. ATMOSPHERIC FATE Zero Ozone Depletion Potential (ODP). Atmospheric lifetime approximately 0.8 yr.;. Global Warming Potential (GWP) 50 ( IO0-yr 1TH. IPCCl995 method). Global Warming Potential (GWP) 55 ( JOO-yr 1TH, 1PCC2001 method) Atmospheric degradation products are expected to include for etl1yl nonfluoroisobutyl ether predominantly isoperfluorobutyric acid, CO2, HF, and perhaps also CFJCOOH; for ethyl nonHuorobutyl ether: n-perfluorobutyric acid, CO2, and HF.
