OSHA OCCUPATIONAL EXPOSURE LIMITS

Acute Health Hazards

THRESHOLD LIMIT VALUE 100 PPM (ACGIH – Time weighted average) EFFECTS OF OVEREXPOSURE Eye Contact: Skin Contact Liquid is minimally irritating to the eyes. High vapor concentrations may also be irritating. Liquid is mildly irritating to the skin. Prolonged or repeated liquid contact can result in defatting and drying of the skin which may result in skin irritation and dermatitis. Inhalation Vapors are irritating to the nose, throat and respiratory tract. High vapor concentrations may cause central nervous system depression. Ingestion Liquid is moderately toxic and may be harmful if swallowed; may produce central nervous system depression. Ingestion of product may result in vomiting; aspiration (breathing) of vomitus into the lungs must be avoided as even small quantities may result in aspiration pneumonitis. Carcinogenicity Xylene is not known to be mutagenic, carcinogenic or a skin sensitizer. However, the available experimental data are

Medical Conditions Generally Aggravated by Exposure

Pre-existing eye, skin and respiratory disorders may be aggravated by exposure to this product. Exposure to high concentrations of this material may cause irregular heartbeats (arrhythmias). Persons with pre- existing heart disorders may be more susceptible to this effect.

Potential chronic health

This product contains Ethyl Benzene. A draft report on a study conducted by the National Toxicology program states that lifetime inhalation exposure of rats and mice to concentrations of Ethyl Benzene (750 ppm) resulted in increases in certain types of cancer, including kidney tumors in rats and lung and liver tumors in mice. These effects were not observed in animals exposed to lower concentration of Ethyl Benzene (75 ppm or 250 ppm). The draft report does not address the relevance of these results to humans. The International Agency for Research on Cancer has evaluated ethylbenzene and classified it as a possible human carcinogen (Group 2B) based on sufficient evidence for carcinogenicity in experimental animals, but inadequate evidence for cancer in exposed humans. SECTION 7 -- REACTIVITY DATA Stability Conditions to Avoid Incompatibility (Materials to Avoid) Stable Heat, sparks and flame. Strong oxidizing agents like liquid chlorine or concentrated oxygen, concentrated nitric and sulfuric acids, halogen and molten sulphur. Hazardous Decomposition Products: Thermal decomposition may yield carbon dioxide and carbon monoxide. Hazardous Polymerization: Will not occur. SECTION 8 -- SPILL OR LEAK PROCEDURES Steps to be taken in case material is spilled or released: Remove ignition sources, evacuate area, avoid breathing vapors or contact with liquid. Recover free liquid or stop leak if possible. Dike large spills and use absorbent material for small spills. Keep spilled material out of sewers, ditches and bodies of water. Waste disposal method: Incinerate under safe conditions; dispose of in accordance with local, state and federal regulations. Trade Name: XYLENE (XYLOL) SECTION 9 -- SAFE HANDLING AND USE INFORMATION Respiratory Protection: Appropriate organic vapor canister, self-contained breathing apparatus or supplied-air hose mask, if needed. Ventilation: Exposure levels should be maintained below applicable exposure limits - see Section 2. This product should not be used in confined spaces, or in a manner that will allow accumulation of high vapor concentrations. However, for controlled industrial uses when this product is used in confined spaces, heated above ambient temperatures or agitated, the use of explosion proof ventilation equipment is necessary. Protective Gloves: Wear resistant gloves, such as nitrile rubber. Eye Protection: Chemical safety goggles. Eye wash and quick-drench shower facilities should be available in the work area. Other Protective Equipment: Impervious clothing or boots, if needed. SECTION 10 -- SPECIAL PRECAUTIONS Dept. of Labor Storage Category: Flammable Liquid - Class IC. Hygienic Practices: Keep away from heat, sparks and open flame. Keep containers closed when not in use. Avoid eye contact. Avoid prolonged or repeated contact with skin. Wash skin with soap and water after contact. Additional Precautions: Ground containers when transferring liquid to prevent static accumulation and discharge. Additional information regarding safe handling of products with static accumulation potential can be ordered by contacting the American Petroleum Institute (API) for API Recommended Practice 2003, entitled "Protection Against Ignitions Arising Out of Static, Lighting, and Stray Currents" (American Petroleum Institute, 1720 L Street Northwest, Washington,DC 20005), or the National Fire Protection Association (NFPA) for NFPA 77 entitled "Static Electricity" (National Fire Protection Association, 1 Batterymarch Park, P.O. Box 9101, Quincy, MA 02269-9101). Empty Container Warning: "Empty" containers retain residue (liquid and/or vapor) and can be dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind or expose such containers to heat, flame, sparks or other sources of ignition. They may explode and cause injury or death. Do not attempt to clean since residue is difficult to remove. "Empty" drums should be completely drained, properly bunged and promptly returned to supplier or disposed of in an environmentally safe manner and in accordance with governmental regulations.
