Warning

SECTION 2: Hazards identification

3.1 EMERGENCY OVERVIEW Specific Physical Form: Liquid Odor, Color, Grade: clear, colorless with slight odor. General Physical Form: Liquid Immediate health, physical, and environmental hazards: May cause target organ effects.

Potential health effects

Eye Contact: Moderate Eye Irritation: Signs/symptoms may include redness, swelling, pain, tearing, and blurred or hazy vision. Skin Contact: Moderate Skin Irritation: Signs/symptoms may include localized redness, swelling, itching, and dryness. Inhalation: Respiratory Tract Irritation: Signs/symptoms may include cough, sneezing, nasal discharge, headache, hoarseness, and nose and throat pain. Cardiac Sensitization: Signs/symptoms may include irregular heartbeat (arrhythmia), faintness, chest pain, and may be fatal. If thermal decomposition occurs: May be harmful if inhaled. May be absorbed following inhalation and cause target organ effects. Ingestion: Gastrointestinal Irritation: Signs/symptoms may include abdominal pain, stomach upset, nausea, vomiting and diarrhea. Target Organ Effects: Central Nervous System (CNS) Depression: Signs/symptoms may include headache, dizziness, drowsiness, incoordination, nausea, slowed reaction time, slurred speech, giddiness, and unconsciousness.

Environmental effects

AQUATIC TOXICITY: Testing results indicate that ethyl nonafluoroisobutyl ether, ethyl nonafluorobutyl ether, methyl nonafluoroisobutyl ether and methyl nonafluorobutyl ether have insignificant toxicity to aquatic organisms at their saturation point (Lowest LC50, EC50, or IC50 > substance water solubility). 1,2-Trans-dichloroethylene is harmful to aquatic organisms (10 mg/L < Lowest LC50, EC50, or IC50 < 100 mg/L). These compounds are highly volatile and have high Henry's Law constants and are 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. BIOCONCENTRATION: Ethyl nonafluoroisobutylether, ethyl nonafluorobutylether, methyl nonafluoroisobutylether, and methyl nonafluorobutylether are highly insoluble and very volatile. Bioconcentration is therefore unlikely and not expected as they are not likely to enter aqueous waste streams from typical uses and disposal, or, in the case of a spill, remain in the aquatic or terrestrial compartments. The high potential for these components to move from aquatic or terrestrial environments to the atmosphere indicates bioconcentration is unlikely to occur as they are not expected to be bioavailable. Thus, emphasis has been placed on the atmospheric fate. 1,2-Trans-dichloroethylene has an octanol/water partition coefficient of <3 indicating it is unlikely to bioconcentrate. ATMOSPHERIC FATE: This product has Zero Ozone Depletion Potential (ODP). Atmospheric Lifetime: approximately 6 days for 1,2-trans-dichloroethylene; approximately 4.7 years and 3.7 years for methyl nonafluoroisobutyl ether and methyl nonafluorobutyl ether, respectively; 0.8 years for the mixture of ethyl nonafluoroisobutyl ether and ethyl nonafluorobutyl ether. Global Warming Potential (GWP): 320 (100 year ITH, WMO 1998 method) for methyl nonafluoroisobutyl ether and methyl nonafluorobutyl ether; 55 (100-yr ITH) for ethyl nonafluoroisobutyl ether and ethyl nonafluorobutyl ether using the calculation method outlined in Climate Change 2001; and essentially zero for 1,2-trans-dichloroethylene. GWP of product as formulated: approximately 43 (100-yr ITH). Ethyl nonafluoroisobutylether, ethyl nonafluorobutylether, methyl nonafluoroisobutylether, and methyl nonafluorobutylether are exempt from the US EPA definition of a volatile organic compound (VOC). Take precautions to prevent direct release to the environment.
