ETHYLBENZENE ICSC: 0268 Ethylbenzol Phenylethane EB C8H10/C6H5C2H5 Molecular mass: 106.2 ICSC #    0268 CAS #     100-41-4 RTECS # DA0700000 UN #        1175 EC #         601-023-00-4 Types of Hazard/ Exposure Acute Hazards/ Symptoms Prevention First Aid/ Fire Fighting FIRE Highly flammable. NO open flames, NO sparks, and NO smoking. Dry powder. Foam. Carbon dioxide. Explosion Vapour/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging or handling. In case of fire: keep drums, etc., cool by spraying with water. Exposure PREVENT GENERATION OF MISTS!  •Inhalation Cough. Sore throat. Dizziness. Drowsiness. Headache. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •Skin Redness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •Eyes Redness. Pain. crimation; deleted at update Nov 07 - only at very high levels. Safety goggles First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •Ingestion Burning sensation in the throat and chest. (Further see Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Refer for medical attention. Spillage Disposal Storage Packaging & Labelling Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer Do NOT let this chemical enter the environment. Fireproof. Separated from strong oxidants. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access. F symbol Xn symbol R: 11-20 S: 2-16-24/25-29 UN Hazard Class: 3 UN Packing Group: II Signal: Danger Flame-Excl mark-Health haz Highly flammable liquid and vapour May be harmful if swallowed Harmful if inhaled vapour Causes mild skin irritation Causes eye irritation Suspected of causing cancer May cause respiratory irritation May cause drowsiness or dizziness May be harmful if swallowed and enters airways Toxic to aquatic life ETHYLBENZENE ICSC: 0268 Important Data Physical State; Appearance: COLOURLESS LIQUID , WITH AROMATIC ODOUR. Physical Dangers: The vapour mixes well with air, explosive mixtures are easily formed. Chemical Dangers: Reacts with strong oxidants. Attacks plastic and rubber. Occupational Exposure Limits: TLV: 100 ppm as TWA, 125 ppm as STEL; A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued, (ACGIH 2007). EU OEL: 442 mg/m3 100 ppm as TWA 884 mg/m3 200 ppm as STEL (skin) (EU 2006). OSHA PEL: TWA 100 ppm (435 mg/m3) NIOSH REL: TWA 100 ppm (435 mg/m3) ST 125 ppm (545 mg/m3) NIOSH IDLH: 800 ppm 10%LEL See: 100414 Routes of Exposure: The substance can be absorbed into the body by inhalation of its vapour, and by ingestion. Inhalation Risk: A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. Effects of Short-Term Exposure: The substance is irritating to the eyes , the skin and the respiratory tract Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis. The substance may cause effects on the central nervous system. Exposure above the OEL could cause lowering of consciousness. Effects of Long-Term or Repeated Exposure: This substance is possibly carcinogenic to humans. The substance may have effects on the kidneys and liver , resulting in impaired functions Repeated contact with skin may cause dryness and cracking.
