FIRST AID MEASURESSkinImmediate first aid is not likely to be required.

3 This material can be removed with soap and water. Wash heavily contaminatedclothing before rinse with plenty of water. If easy to do, remove any contact lenses. Rinse under the eyelids, for at least 15 medical attention if irritation develops or inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Remove materialfrom eyes, skin and victim rinse mouth thoroughly with water. If swallowed, do NOT inducevomiting. Never give anything by mouth to a victim who is unconscious or ishaving convulsions. If vomiting occurs naturally, have victim lean forward toreduce risk of aspiration.

4 Obtain medical FIRE FIGHTING MEASURESG eneral fire hazardsVapors may form explosive mixtures with air. Vapors are heavier than air andmay travel along the ground to some distant source of ignition and flash mediaSuitable extinguishing media. Dry chemical, CO2, water spray or regular extinguishing mediaDo not use water of firefightersSpecific hazards arising from the chemicalNone equipment and precautions for firefightersWear full protective clothing, including helmet, self-contained positivepressure or pressure demand breathing apparatus, protective clothing and containers from fire area if you can do it without combustion productsCombustion products include fumes, smoke, carbon monoxide and carbon and toxic gases or fumes may be released during a temperature.

ACCIDENTAL RELEASE MEASURESPage: 2 SDS: DIBASIC ESTERP ersonal precautionsKeep unnecessary personnel away. Local authorities should be advised if significant spillages cannot be precautionsDo not let product enter drains. Do not flush into surface for containmentStop the flow of material, if this is without risk. Dike the spilled material, wherethis is possible. Prevent entry into waterways, sewers, basements or confined for cleaning upLarge Spills: Dike far ahead of liquid spill for later disposal.

6 Use a non-combustible material like vermiculite, sand or earth to soakup the product and place into a container for later Spills: Wipe up with absorbent material ( cloth, fleece). Clean contaminated surface informationClean up in accordance with all applicable HANDLING AND STORAGEH andlingFollow all MSDS/label precautions even after container is emptied because it may retain product residues. Do not breathegas/fumes/vapor/spray. Do not get this material in contact with skin or eyes. Use this product with adequate ventilation. Use non-sparking tools when opening or closing tightly closed in a dry, cool and well-ventilated place.

7 Keep away from heat, sparks, and flame. Store away from natural or mechanical ventilation to control exposure levels below airborne limits (see below). The use of local mechanicalexhaust ventilation at sources of air contamination such as open process equipment is Exposure Limits have not been manufacturer recommends an airborne exposure guideline of 10 mg/m3 ( ppm) (8-hr. TWA) for this EXPOSURE CONTROLS AND PERSONAL PROECTIONEye Protection: Personal Protection Equipments (PPE)Where there is significant potential for eye contact, wear chemical goggles and have eye flushing equipment Protection: Personal Protection Equipments (PPE)Although this product does not present significant skin concern, minimize skin contamination by following good industrial protective gloves is recommended.

8 Wash hands and contaminated skin thoroughly after Protection: Personal Protection Equipments (PPE)Avoid breathing vapor or mist. Use NIOSH/MSHA approved respiratory protection equipment when airborne limits are exceeded(see above). Consult the respirator manufacturer to determine the appropriate type of equipment for a given application. Observerespirator use limitations specified by NIOSH/MSHA or the manufacturer.
