SECTION 2: Hazards identification

OSHA 3.1 EMERGENCY OVERVIEW Specific Physical Form: liquid Odor, Color, Grade: Clear, colorless, liquid. Slight ethereal odor. General Physical Form: Liquid Immediate health, physical, and environmental hazards:

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: If thermal decomposition occurs: Respiratory Effects: Signs/symptoms may include cough, sneezing, shortness of breath, chest tightness, nasal discharge, and wheezing. Ingestion: No health effects are expected.

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 product to the environment. AQUATIC TOXICITY: Testing results indicate that this product has insignificant toxicity to aquatic organisms at its saturation point (Lowest LC50, EC50, or IC50 > substance water solubility). 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 4.1 yrs. Global Warming Potential (GWP) 280 (100 year ITH, IPCC1995 method). Global Warming Potential (GWP) 320 (100 yr ITH, IPCC2001 method) Atmospheric degradation products are expected to include for methyl nonafluoroisobutyl ether predominantly isoperfluorobutyric acid, CO2, HF, and perhaps also CF3COOH; for methyl nonafluorobutyl ether: n-perfluorobutyric acid, CO2, and HF. SECTION 4: FIRST AID MEASURES 4.1 FIRST AID PROCEDURES The following first aid recommendations are based on an assumption that appropriate personal and industrial hygiene practices are followed. Eye Contact: Flush eyes with large amounts of water. If signs/symptoms persist, get medical attention. Skin Contact: Wash affected area with soap and water. If signs/symptoms develop, get medical attention. Inhalation: If signs/symptoms develop, remove person to fresh air. If signs/symptoms develop, get medical attention. If Swallowed: If signs/symptoms develop, get medical attention. No need for first aid is anticipated. SECTION 5: FIRE FIGHTING MEASURES 5.1 FLAMMABLE PROPERTIES Autoignition temperature 405 ºC [Details: (ASTM E659-84)] Flash Point Not Applicable Flammable Limits - LEL [Details: NONE acc to ASTM E681-94, @100C] Flammable Limits - UEL [Details: NONE acc to ASTM E681-94, @100C] 5.2 EXTINGUISHING MEDIA Material will not burn. 5.3 PROTECTION OF FIRE FIGHTERS Special Fire Fighting Procedures: Water may be used to blanket the fire. Exposure to extreme heat can give rise to thermal decomposition. Wear full protective equipment (Bunker Gear) and a self-contained breathing apparatus (SCBA). Unusual Fire and Explosion Hazards: No unusual fire or explosion hazards are anticipated. No unusual effects are anticipated during fire extinguishing operations. Avoid breathing the products and substances that may result from the thermal decomposition of the product or the other substances in the fire zone. Keep containers cool with water spray when exposed to fire to avoid rupture. Note: See STABILITY AND REACTIVITY (SECTION 10) for hazardous combustion and thermal decomposition information. SECTION 6: ACCIDENTAL RELEASE MEASURES Accidental Release Measures: Observe precautions from other sections. Call 3M- HELPS line (1-800-364-3577) for more information on handling and managing the spill. Ventilate the area with fresh air. Contain spill. Working from around the edges of the spill inward, cover with bentonite, vermiculite, or commercially available inorganic absorbent material. Mix in sufficient absorbent until it appears dry. Collect as much of the spilled material as possible. Clean up residue with an appropriate organic solvent. Read and follow safety precautions on the solvent label and MSDS. Collect the resulting residue containing solution. Place in a metal container approved for transportation by appropriate authorities. Seal the container. Dispose of collected material as soon as possible. In the event of a release of this material, the user should determine if the release qualifies as reportable according to local, state, and federal regulations. SECTION 7: HANDLING AND STORAGE 7.1 HANDLING Avoid skin contact with hot material. For industrial or professional use only. Contents may be under pressure, open carefully. No smoking: Smoking while using this product can result in contamination of the tobacco and/or smoke and lead to the formation of the hazardous decomposition products mentioned in the Reactivity Data section of this MSDS. Store work clothes separately from other clothing, food and tobacco products. Use general dilution ventilation and/or local exhaust ventilation to control airborne exposures to below Occupational Exposure Limits. If ventilation is not adequate, use respiratory protection equipment. Avoid continuous exposure of the material to extreme conditions of heat, i.e., above 150 C (welding, open flame, misuse or equipment failure). Avoid exceeding a watt density of 50 watts/inch2 from a heater surface. Continuous exposure to 150 C results in very slight decomposition of this product and therefore, is a very conservative use temperature threshold. Applications involving exposure of the fluid to temperatures exceeding 150 C or watt densities exceeding 50 watts/inch2 have been safely implemented. Applications which may exceed these use parameters should be reviewed with 3M Technical Service.

Storage

Keep container tightly closed. Keep container in well-ventilated area. Store away from heat. Store away from strong bases. SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION 8.1 ENGINEERING CONTROLS Use with appropriate local exhaust ventilation. Provide local exhaust ventilation at transfer points. Provide appropriate local exhaust when product is heated. For those situations where the fluid might be exposed to extreme overheating due to misuse or equipment failure, use with appropriate local exhaust ventilation sufficient to maintain levels of thermal decomposition products below their exposure guidelines. 8.2 PERSONAL PROTECTIVE EQUIPMENT (PPE) 8.2.1 Eye/Face Protection Avoid eye contact. The following eye protection(s) are recommended: Safety Glasses with side shields. 8.2.2 Skin Protection Avoid skin contact with hot material. Wear appropriate gloves, such as Nomex, when handling this material to prevent thermal burns. Select and use gloves and/or protective clothing to prevent skin contact based on the results of an exposure assessment. Consult with your glove and/or protective clothing manufacturer for selection of appropriate compatible materials. Gloves made from the following material(s) are recommended: Nitrile Rubber. 8.2.3 Respiratory Protection Avoid breathing of vapors, mists or spray. Under normal use conditions, airborne exposures are not expected to be significant enough to require respiratory protection. Select one of the following NIOSH approved respirators based on airborne concentration of contaminants and in accordance with
