Medical Conditions Generally Aggravated by Exposure

Allergy, skin disorders. Emergency and First Aid Procedures EYES - Flush with water, holding lids open for 15 minutes or more. Call physician for advice if necessary. SKIN - PROMPTLY wash with soap and water. DO NOT wash with solvents. Seek medical advice if irritation develops or persists. INHALATION - Move person to fresh air if effects occur. If needed, give oxygen or artificial respiration to improve breathing . Consult physician. INGESTION - Get medical attention immediately. Never give liquids to an unconscious or convulsing person. SECTION VII - CONTROL MEASURES Respiratory Protection (Specify Type) Provide adequate exhaust ventilation; use a NIOSH approved respirator if PELS/TLVS are exceeded. Ventilation Local Exhaust If needed. Special None known. Mechanical Adequate exhaust ventilation must exhaust AWAY from applicator. Protective Gloves Natural rubber or Neoprene. Eye Protection Splash goggles or face shield. Other Protective Clothing or Equipment Use rubber apron, face shield and appropriate clothing to prevent contact with skin. Launder contaminated clothing before reuse. Discard contaminated leather shoes and canvas sneakers. Protective skin creams help cleaning with soap and water, gloves must still be worn. An eye wash station or an adequate supply of clean water must be available at work area. Work/Hygienic Practices Enforce careful handling to prevent splashing. Wash thoroughly after use. SECTION VIII - PRECAUTIONS FOR SAFE HANDLING AND USE Steps to be Taken in Case Material is Released or Spilled Wear protective equipment to prevent exposure. Stop spill and dike to prevent spreading. Cover spill with absorbent materials and collect into containers. Clean contaminated area with detergent and water or a steam cleaner for best results. Waste Disposal Method Dispose in accordance with Federal, State and Local requirements. Precautions to be Taken in Handling and Storing Keep containers tightly closed when not in use. Other Precautions NONE KNOWN. Prepared by Murty Bhamidipati PLEASE "The above information is accurate to the best of our knowledge.
