Version 1.6 Regulation (EC) No 1907/2006 1 - Product and Company Information Product NameACETIC ACID-UL-14C 2 - Hazards Identification SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT Flammable. Causes severe burns. 3 - Composition/Information on Ingredients Product NameCAS #EC noAnnex I Index Number ACETIC ACID-1-14C2845-03-6 NoneNone FormulaC2H4O2 Molecular Weight 60,0500 AMU 4 - First Aid Measures AFTER INHALATION If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen. AFTER SKIN CONTACT In case of skin contact, flush with copious amounts of water for at least 15 minutes. Remove contaminated clothing and shoes. Call a physician. AFTER EYE CONTACT In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Call a physician. AFTER INGESTION If swallowed, wash out mouth with water provided person is conscious. Call a physician immediately. Do not induce vomiting. 5 - Fire Fighting Measures SIGMAwww.molbase.com EXTINGUISHING MEDIA Suitable: For small (incipient) fires, use media such as "alcohol" foam, dry chemical, or carbon dioxide. For large fires, apply water from as far as possible. Use very large quantities (flooding) of water applied as a mist or spray; solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. SPECIAL RISKS Specific Hazard(s): Flammable liquid. Emits toxic fumes under fire conditions. Explosion Hazards: Vapor may travel considerable distance to source of ignition and flash back. Container explosion may occur under fire conditions. SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes. 6 - Accidental Release Measures PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL Evacuate area. Handle as a radioactive spill. PROCEDURE(S) OF PERSONAL PRECAUTION(S) Wear self-contained breathing apparatus, rubber boots, and heavy rubber gloves. METHODS FOR CLEANING UP Cover with dry-lime, sand, or soda ash. Place in covered containers using non-sparking tools and transport outdoors. Ventilate area and wash spill site after material pickup is complete. 7 - Handling and Storage HANDLING Directions for Safe Handling: Do not breathe vapor. Do not get in eyes, on skin, on clothing. Avoid prolonged or repeated exposure. STORAGE Conditions of Storage: Keep tightly closed. Keep away from heat, sparks, and open flame. Store at 2-8°C 8 - Exposure Controls / Personal Protection ENGINEERING CONTROLS Safety shower and eye bath. Use nonsparking tools. Use only in a chemical fume hood. GENERAL HYGIENE MEASURES Wash contaminated clothing before reuse. Discard contaminated shoes. Wash thoroughly after handling. PERSONAL PROTECTIVE EQUIPMENT Respiratory Protection: Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Where risk assessment shows air-purifying respirators SIGMAwww.molbase.com are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Hand Protection: Compatible chemical-resistant gloves. Eye Protection: Chemical safety goggles. Special Protective Measures: Faceshield (8-inch minimum). 9 - Physical and Chemical Properties AppearancePhysical State: Liquid PropertyValueAt Temperature or Pressure pH N/A BP/BP RangeN/A MP/MP RangeN/A Flash Point40,000 °CMethod: closed cup FlammabilityN/A Autoignition Temp427,00 °C Oxidizing Properties N/A Explosive Properties N/A Explosion LimitsLower: 4,000 % Upper: 16,000 % Vapor Pressure11,400000000 mmHg 20,00 °C Partition Coefficient N/A ViscosityN/A Vapor Density2,070 g/l Saturated Vapor Conc.

HAZARDOUS POLYMERIZATION Hazardous Polymerization: Will not occur 11 - Toxicological Information SIGNS AND SYMPTOMS OF EXPOSURE Ingestion or inhalation of concentrated acetic acid causes damage to tissues of the respiratory and digestive tracts. Symptoms include: hematemesis, bloody diarrhea, edema and/or SIGMAwww.molbase.com perforation of the esophagus and pylorus, hematuria, anuria, uremia, albuminuria, hemolysis, convulsions, bronchitis, pulmonary edema, pneumonia, cardiovascular collapse, shock, and death. Direct contact or exposure to high concentrations of vapor with skin or eyes can cause: erythema, blisters, tissue destruction with slow healing, skin blackening, hyperkeratosis, fissures, corneal erosion, opacification, iritis, conjunctivitis, and possible blindness. To the best of our knowledge, the chemical, physical, and toxicological properties have not been thoroughly investigated. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. Inhalation may result in spasm, inflammation and edema of the larynxand bronchi, chemical pneumonitis, and pulmonary edema. Material is extremely destructive to tissue of the mucous membranes and upper respiratory tract, eyes, and skin. ROUTE OF EXPOSURE Skin Contact: Causes burns. Skin Absorption: May be harmful if absorbed through the skin. Eye Contact: Causes burns. Inhalation: May be harmful if inhaled. Material is extremely destructive to the tissue of the mucous membranes and upper respiratory tract. Ingestion: May be harmful if swallowed. TARGET ORGAN INFORMATION Teeth. Kidneys. CONDITIONS AGGRAVATED BY EXPOSURE Severe, acute pancreatitis may occur after ingestion of concentrated acetic acid. CHRONIC EXPOSURE - CARCINOGEN Result: Contains a radioactive isotope which may produce cancer and genetic mutation. 12 - Ecological Information No data available. 13 - Disposal Considerations SUBSTANCE DISPOSAL Dispose of spilled material as radioactive waste. Consult local, state, and federal regulations on the disposal of radioactive waste. Observe all federal, state, and local environmental regulations. 14 - Transport Information RID/ADR UN#: 2910 Class: 7 Proper Shipping Name: Radioactive material, excepted package, limited quantity of material IMDG UN#: 2910 Class: 7 SIGMAwww.molbase.com Proper Shipping Name: RADIOACTIVE MATERIAL, EXCEPTED PACKAGE - LIMITED QUANTITY OF MATERIAL Marine Pollutant: No Severe Marine Pollutant: No IATA UN#: 2910 Class: 7 Proper Shipping Name: Radioactive material, excepted package, limited quantity of material Inhalation Packing Group I: No 15 - Regulatory Information CLASSIFICATION AND LABELING ACCORDING TO EU DIRECTIVES INDICATION OF DANGER: R-C Radioactive.
