International Chemical Safety Cards 2-CHLOROACETAMIDE ICSC: 0640 2-CHLOROACETAMIDE alpha-Chloroacetamide C2H4ClNO/ClCH2CONH2 Molecular mass: 93.5 CAS # 79-07-2 RTECS # AB5075000 ICSC # 0640 UN # 2811 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION Solutions may explode during drying or concentration operations. EXPOSURE PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! INHALATION Burning sensation. Cough. Sore throat. Avoid inhalation of fine dust and mist. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention. SKIN Redness. Pain. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. EYES Redness. Pain. Safety spectacles, face shield, or eye protection in combination with breathing protection if powder. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. INGESTION Sore throat. Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P3 filter respirator for toxic particles). Separated from strong oxidants, strong bases, strong acids, food and feedstuffs. Keep in a well-ventilated room. Do not transport with food and feedstuffs. UN Hazard Class: 6.1 SEE IMPORTANT INFORMATION ON BACK ICSC: 0640 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities © IPCS CEC 1993 No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and IDLH values.
