OSHA OCCUPATIONAL EXPOSURE LIMITS ACGIH

Potential chronic health

There is no evidence that exposure to Methyl Ethyl Ketone alone causes progressive or irreversible neurotoxic effects. However, simultaneous overexposure to MEK and n-Hexane can potentiate the known irreversible neurotoxic effects of n-Hexane. There is no reported human evidence that these neurotoxic effects occur when exposure to both chemicals is maintained below established

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. SECTION 7 -- REACTIVITY DATA Stability: Stable Conditions to Avoid: Heat, sparks, and flame. Incompatibility (Materials to Avoid): Strong oxidizing agents like liquid chlorine or concentrated oxygen. Hazardous Decomposition Products: Thermal decomposition may yield 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: Send to a licensed reclaimer or incinerator. Dispose of in accordance with local, state and federal regulations. SECTION 9 -- SAFE HANDLING AND USE INFORMATION Respiratory Protection: Where concentrations in air may exceed occupational exposure limits. NIOSH/MSHA approved respirations may be necessary to prevent overexposure by inhalation. Ventilation: Sufficient, in volume and pattern, to keep workroom concentration below current applicable OSHA safety and health requirements. See Section 2. Use explosion-proof ventilation equipment. No smoking. Protective Gloves: Wear resistant gloves such as nitrile rubber. Eye Protection: Chemical safety goggles and a face shield. Other Protective Equipment: Impervious clothing or boots where needed. SECTION 10 -- SPECIAL PRECAUTIONS Dept. of Labor Storage Category: Flammable liquid - Class IB. Hygienic Practices: Keep away from heat, sparks and flame. Keep containers closed when not in use. Avoid eye contact. Avoid prolonged 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.
