NO open flames. Powder, carbon dioxide foam . Explosion Above 68°C explosive vapour/air mixtures may be formed. Above 68°C use a closed system, ventilation. Exposure PREVENT GENERATION OF MISTS!  •Inhalation Cough. Dizziness. Drowsiness. Headache. Nausea. Sore throat. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.  •Skin Dry skin. Redness. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.  •Eyes Redness. Pain. Safety spectacles or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •Ingestion Abdominal pain. Diarrhoea. (Further see Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Give one or two glasses of water to drink. 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. Collect leaking and spilled liquid in sealable containers as far as possible. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Separated from strong oxidants. Dry.

MAK: 50 ppm 210 mg/m3 Peak limitation category: I(1); skin absorption (H); Pregnancy risk group: D; (DFG 2006). OSHA PEL: TWA 50 ppm (200 mg/m3) NIOSH REL: TWA 50 ppm (200 mg/m3) skin NIOSH IDLH: 400 ppm See: 108930 Routes of Exposure: The substance can be absorbed into the body by inhalation and by ingestion. Inhalation Risk: A harmful contamination of the air will not or will only very slowly be reached 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 . The substance may cause effects on the central nervous system . Effects of Long-Term or Repeated Exposure: The liquid defats the skin.
