SECTION 2: Hazards identification

EMERGENCY OVERVIEW: This is a an extremely flammable liquid with an ether-like odor. This product comes in a variety of colors. Inhalation overexposures to the vapors of this product can cause central-nervous system effects (including dizziness, drowsiness, nausea, and headaches). This product can be mildly to severely irritating to the eyes, skin, and other contaminated tissue. Vapors of this product are heavier than air and may travel to a source of ignition and flashback to a leak or open container. Tetrahydrofuran, a component of this product, is known to form explosive peroxides under certain circumstances. Emergency responders must wear the proper personal protective equipment (and have appropriate fire protection) suitable for the situation to which they are responding. SYMPTOMS OF OVEREXPOSURE BY ROUTE OF EXPOSURE: The most significant routes of occupational overexposure are inhalation and | HAZARDOUS MATERIAL INFORMATION SYSTEM contact with skin and eyes. The symptoms of overexposure to this product, via route of entry, are as follows: HEALTH (BLUE) | 2 INHALATION: inhalation of vapors, mists, or sprays of this product can be irritating to the nose, throat, mucous membranes, and other tissues of. the respiratory system. Symptoms of overexposure can include coughing, sneezing, and shortness of breath. Additionally, the components of this product are central nervous system depressants. FLAMMABILITY (RED) | 3 Symptoms of over-exposure can include drowsiness, dizziness, fatigue, headache, nausea, and general anesthetic effects.

The liquid can be mildly to severely irritating to contaminated skin (depending on duration of exposure). Prolonged or repeated skin over-exposures can lead to dermatitis. SKIN ABSORPTION: Skin absorption is a potential route of See Definition Section 16 for of Ratings overexposure for Cyclohexanone (a component of this product). Symptoms of such exposure can include those described under “Inhalation” and “Contact With Skin and Eyes’. INGESTION: Ingestion is not anticipated to be a significant route of occupational overexposure for this product. If ingestion occurs, refer to Section 4 (First-Aid Measures) and get medical help immediately. If ingestion of this product does occur, symptoms of such over-exposure can include nausea, vomiting, and other symptoms described for “Inhalation”. Ingestion can also lead to liver and kidney damage.. Ingestion of this product may be fatal. INJECTION: Injection is not anticipated to be a significant route of over-exposure for this product. If injection does occur (i.e. through a puncture by an object contaminated with the product), focal irritation and swelling can occur. Additional symptoms may include those described for “Inhalation”. HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation i T ACUTE: Over-exposures to this product can be irritating to the eyes, skin, and mucous membranes, and can also cause centrai-nervous system effects (dizziness, drowsiness, nausea and headaches). Ingestion of this product, or inhalation of high concentrations of this product's vapors, may be fatal. CHRONIC: Prolonged or repeated skin exposures can lead to dermatitis (dryness, reddening and irritation of the skin). Tetrahydrofuran, a component of this product, may cause fiver and kidney damage after long-term inhalation -overexposures. There is limited evidence from animal studies that Methyl Ethy! Ketone, a component of this product, is a reproductive toxin. Refer to Section 11 (Toxicological Information) for additional information. A report from the National Toxicology Program (NTP) on inhalation studies in rats and mice suggests that THF can cause tumors in animals. In the study the rats and mice were exposed to levels to 1800 ppm for a two year lifespan 6 hours a day, 5 days a week. Evidence of liver tumors in female mice and kidney tumors in male rats was observed in the test. No evidence of tumors were seen in female rats or male mice. There is no data linking THF exposure with cancer in humans. AE AMEN ARARLIATO Meno PART Il what should | do if a hazardous situation occurs?
