3M Novec 7100 Engineered Fluid

SECTION 2: Hazards identification

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: May be harmful if inhaled. 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. No need for first aid is anticipated. Skin Contact: Wash affected area with soap and water. If signs/symptoms develop, get medical attention. No need for first aid is anticipated. Inhalation: If signs/symptoms develop, remove person to fresh air. If signs/symptoms persist, get medical attention. If Swallowed: 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 No flash point Flammable Limits(LEL) None detected Flammable Limits(UEL) None detected 5.2 EXTINGUISHING MEDIA Non-combustible. Choose material suitable for surrounding fire. 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 6.1. Personal precautions, protective equipment and emergency procedures Ventilate the area with fresh air. 6.2. Environmental precautions For larger spills, cover drains and build dikes to prevent entry into sewer systems or bodies of water. Collect the resulting residue containing solution. Place in a metal container approved for transportation by appropriate authorities. Dispose of collected material as soon as possible. Clean-up methods Observe precautions from other sections. Call 3M- HELPS line (1-800-364-3577) for more information on handling and managing the spill. 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. Seal the container. 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 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. 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. Under certain conditions, 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

Store away from heat. Keep container tightly closed. Store away from strong bases. SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION 8.1 ENGINEERING CONTROLS For those situations where the material 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 As a good industrial hygiene practice: Avoid eye contact. 8.2.2 Skin Protection As a good industrial hygiene practice: Avoid prolonged or repeated skin contact. 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 Under normal use conditions, airborne exposures are not expected to be significant enough to require respiratory protection. 8.2.4 Prevention of Swallowing Wash hands after handling and before eating. 8.3 EXPOSURE GUIDELINES Ingredient Authority Type Limit Additional Information Methyl nonafluorobutyl ether AIHA TWA 750 ppm Methyl nonafluoroisobutyl ether AIHA TWA 750 ppm SOURCE OF EXPOSURE LIMIT DATA: ACGIH: American Conference of Governmental Industrial Hygienists CMRG: Chemical Manufacturer Recommended Guideline OSHA: Occupational Safety and Health Administration AIHA: American Industrial Hygiene Association Workplace Environmental Exposure Level (WEEL)
