1 MATERIAL SAFETY DATA SHEET Section 1 Chemical Product and Company Identification MSDS Name 3-Chloro-1 2-Propanediol 98% Synonyms Alpha-Chlorohydrine; Glyceryl Chloride; 3-Chloropropanediol. Company Identification Northeast Pharmaceutical Group Co. Ltd No. 37, Zhonggong Bei Street Tiexi District Shenyang Liaoning P.R. China Section 2 - Composition, Information on Ingredients CAS# Chemical Name % EINECS# Chloro-1,2-Propanediol 98% Hazard Symbols: T Risk Phrases: 23/24/25 Section 3 Hazards Identification EMERGENCY OVERVIEW Toxic by inhalation, in contact with skin and if swallowed.hygroscopic (absorbs moisture from the air). Potential Health Effects Eye: May cause eye irritation. Skin: May cause skin irritation. Ingestion: May be fatal if swallowed. May cause gastrointestinal irritation with nausea, vomiting and diarrhea. Inhalation: May cause respiratory tract irritation. Chronic: Chronic ingestion may cause liver damage. Section 4 - First aid Measures Eyes Skin Ingestion Inhalation Notes to Physician Section 5 - Fire Fighting Measures General Information Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. If irritation develops, get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Get medical aid if symptoms occur. Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water. Get medical aid immediately. Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Do NOT use mouth-to-mouth resuscitation. Treat symptomatically and supportively. As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Extinguishing Media

2 In case of fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. Cool containers with flooding quantities of water until well after fire is out. Section 6 Accidental Release Measures General Information Use proper personal protective equipment as indicated in Section 8. Spills/Leaks Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Clean up spills immediately, observing precautions in the Protective Equipment section. Remove all sources of ignition. Provide ventilation.

3 Section 7 - Handling and Storage Handling Storage Wash thoroughly after handling. Wash hands before eating. Use only in a well-ventilated area. Avoid breathing dust, vapor, mist, or gas. Keep container tightly closed. Keep away from heat, sparks and flame. Use only in a chemical fume hood. Do not store in direct sunlight. Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep containers tightly closed. Section 8 - Exposure Controls, Personal Protection Engineering Controls Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits. Exposure Limits CAS# Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR or European Standard EN166. Skin Wear appropriate gloves to prevent skin exposure. Clothing Wear appropriate protective clothing to minimize contact with skin. Respirators Wear a NIOSH/MSHA or European Standard EN 149 approved full-facepiece airline respirator in the positive pressure mode with emergency escape provisions. Follow the OSHA respirator regulations found in 29 CFR or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
