### 4. FIRST AID MEASURES

Inhalation: Move to fresh air. Give artificial respiration if breathing has stopped. Get prompt medical

attention. In case of shortness of breath, give oxygen.

Skin contact: Remove contaminated clothing. Wash off with soap and plenty of water. Wash contaminated clothing before re-use. Do not take clothing home to be laundered. Consult a physician. Eye contact: Rinse immediately with plenty of water for at least 15 minutes. Get prompt medical

attention. Ingestion: Drink 1 or 2 glasses of water. Do not induce vomiting: contains petroleum distillates and/or

aromatic solvents. Careful gastric lavage may be indicated. IMMEDIATELY see a physician. If vomiting occurs spontaneously, keep airway clear. Never give anything by mouth to an unconscious

person. Notes to physician: Product contains a petroleum distilla te that may cause CNS symptoms. If swallowed, DO NOT induce vomiting due to the ri sk of aspiration posed by petroleum distillates. Careful gastric lavage may be indicated.

Flash point 33 °C ( 91.40 °F ) PENSKY MARTENS CLOSED CUP PENSKY

MARTENS CLOSED CUP

Ignition temperature 527.0 °C ( 980.60 °F ) Xylene

Lower explosion limit 1.10 %(V)Xylene

Upper explosion limit 6.70 %(V)Xylene

Suitable extinguishing media: Use the following extinguishing media when fighting fires involving this

material: Carbon dioxide (CO2) Dry powder

Foam Water in very large quantities.

Specific hazards during fire fighting: Vapors can travel to a source of ignition and flash back. Heated material can form flammable or explosive vapors with air. Closed containers may rupture via pressure build-up when exposed to fire or extreme heat. During a fire, irritating and highly toxic gases and/or fumes may be generated during combustion or decomposition. DO NOT permit water to enter

containers. Closed containers may explode when heated or contents contaminated with water. Special protective equipment for fire-fighters: In the event of fire, wear self-contained breathing apparatus.

Further information: EXPLOSION HAZARD. Fight advanced fires from a protected location. Cool closed containers exposed to fire with water spray. DO NOT permit water to enter containers. Remain upwind. Avoid breathing smoke.

### 6. ACCIDENTAL RELEASE MEASURES

Personal precautions Appropriate protective equipment mu st be worn when handling a spill of this material. See SECTION 8, Exposure Controls/Personal Protection, for recommendations.

MATERIAL IS A POTENTIAL SENSITIZER. If exposed to material during clean-up operations, IMMEDIATELY remove all contaminated clothing and wash exposed skin areas with soap and water. S ee SECTION 4, First Aid Measures, for further

information.

Wash contaminated clot hing before re-use. Do not take clothing home to be laundered. Environmental precautions

WARNING: KEEP SPILLS AND CLEANING RUNOFFS OUT OF MUNICIPAL SEWERS AND OPEN

BODIES OF WATER. Methods for cleaning up Eliminate all ignition sources. Evacuate personnel to safe areas.

Ventilate the area. Floor may be slippery; use care to avoid falling. Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust). Sweep up or vacuum up spillage and collect in suitable container for disposal. No sparking tools should be used.

Avoid all contact. Avoid breathing vapor. NOTE: Spills on porous surfaces can contaminate groundwater.



### 7. HANDLING AND STORAGE

Handling Vapors can be evolved when materi al is heated during processing operations. See SECTION 8, Exposure Controls/Personal Protection , for types of ventilation required. Use non-sparking tools and grounding cables when transferring. This material is a potential sensitizer. See SECTION 8, Exposure Controls/Personal Protection, prior to handling. Wash after handling and shower at end of work period. Persons susceptible to skin sensitisation problems or asthma, allergies, chronic or recurrent respiratory disease should not be employed in any proce ss in which this mixture is being used.

Other data: STIR WELL BEFORE USE. 

### Storage Storage conditions: Avoid temperature extremes during st orage; ambient temperature preferred. Store away from excessive heat (e.g . steampipes, radiators), from sour ces of ignition and from reactive

materials. Material can burn; limit indoor storage to appr oved areas equipped with automatic sprinklers. Store out of direct sunlight in a cool place. Keep containers tightly closed in a cool, well-ventilated place. Avoid all ignition sources. Ground all metal containers during storage and handling. Keep material dry. Moisture may affect product quality. Further information on storage conditions: Residual vapors in empty containers may explode on ignition. DO NOT cut, drill, grind or weld on or near container.

Further information:

CONTAINERS MAY BE HAZARDOUS WHEN EMPTY. Since emptied containers retain product residue follow all MSDS and label warnings even after container is emptied. Improper disposal or re-use of this container ma y be dangerous and illegal. Refer to applicable local, state and federal regulations.COREACTANT 9L7

### Exposure controls Engineering measures: Use explosion-proof local exhaust ventilation with a minimum capture velocity of 100 ft/min (0.5 m/sec) at the point of vapor evolution. Refe r to the current edition of Industrial

Ventilation: A Manual of Recommended Practice published by the American Conference of Governmental Industrial Hygienists for information on the design, installation, use, and maintenance of exhaust systems.


### Protective measures: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. 

### Individual protection measuresCOREACTANT 9L7

Page 7 of 12 Revision date 04/26/2011 Eye/face protection: Use chemical splash goggles (A NSI Z87.1 or approved equivalent). Eye protection worn must be compatible with respiratory protecti on system employed. Skin protection Hand protection: Chemical-resistant gloves should be worn whenever this material is

handled. The glove(s) listed below may provide protection against permeation. (Gloves of other chemically resistant materi als may not provide adequate protection): VITON Synthetic Rubber (registered Tradem ark of Dupont Dow Elastomers) Gloves should be removed and replaced immediately if there is any indication of degradation or chemical breakthrough. Rinse and remove gloves immediately after use. Wash hands with soap

and water. Other protection: Use chemically resistant apron or other impervious clothing to avoid prolonged or repeated skin contact. Where splashing is possible, full chemically resistant protective clothing (e.g. acid suit) and boots are required. Respiratory protection: A respiratory protection program meeting OSHA 1910.134 and ANSI Z88.2 requirements or equivalent must be follo wed whenever workplace conditions warrant a respirator’s use. None required if airborne concentrati ons are maintained below the exposure limit listed in Exposure Limit Information. Above the exposure limit: Wear a properly fitted NIOSH approved (or equivalent) self-contained br eathing apparatus in the pressure demand mode, OR full-facepiece, airline respirator in the pressure demand mode with emergency escape provision.

Component: Propylene glycol methyl ether acetate Reproductive toxicity Dermal teratology testing of this solvent (with less than 3% beta isomer) revealed no maternally toxic, teratogenic or fetotoxic responses in rats or rabbits exposed to concentrations of 1,000 and 2,000 mg/kg per day.COREACTANT 9L7

Page 9 of 12 Revision date 04/26/2011 Component: Propylene glycol methyl ether acetate Mutagenicity No significant mutagenic response was observed and the carcinogenic potential of the material is

therefore considered to be low. Component: Xylene Reproductive toxicity In laboratory studies, birth defects, increased fe tal lethality and delayed fetal development have been observed in offspring of female animals exposed during pregnancy. Component: Ethylbenzene Carcinogenicity : This product contains ethylbenzene. A study conducted by the National Toxicology Program states that lifetime inhalation exposure of rats and mice to high concentrations of ethylbenzene (750 ppm) resulted in increases in certain types of cancer, including kidney tumors in rats and lung and liver tumors in mice. Incidences of testicular adenoma were increased along with increased incidences of thyroid effects in rats at 750 ppm; pituitary effects were observed in female mice at 250 ppm. These effects were not observed in animals exposed to lower concentrations of ethylbenzene (75 ppm). The study does not address the relevance of these results to humans.
