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 distillate that may cause CNS symptoms. If 

swallowed, DO NOT induce vomiting due to the risk of aspiration posed by petroleum distillates. Careful 

gastric lavage may be indicated.

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:

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. 

Contain run-off.

6. ACCIDENTAL RELEASE MEASURES 

Personal precautions 

Appropriate protective equipment must 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. See SECTION 4, First Aid Measures, for further 

information. 

Wash contaminated clothing 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 material 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 process in which this mixture is being used. 

Other data: STIR WELL BEFORE USE. 

Storage

Storage conditions: Avoid temperature extremes during storage; ambient temperature preferred. 

Store away from excessive heat (e.g. steampipes, radiators), from sources of ignition and from reactive 

materials. Material can burn; limit indoor storage to approved 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 may be dangerous and illegal. Refer to applicable local, 

state and federal regulations.

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. Refer 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.

facility and a safety shower. 

Individual protection measures
COREACTANT 9L7

Page 7 of 12 Revision date 04/26/2011 

Eye/face protection: Use chemical splash goggles (ANSI Z87.1 or approved equivalent). Eye 

protection worn must be compatible with respiratory protection 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 materials may not provide adequate protection): VITON 

Synthetic Rubber (registered Trademark 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 followed whenever workplace conditions warrant a 

respirator’s use. None required if airborne concentrations 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 breathing 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

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 fetal 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.
