Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR!  •INHALATION Confusion. Convulsions. Dizziness. Headache. Laboured breathing. Nausea. Vomiting. See Notes. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Artificial respiration if indicated. Refer for medical attention. See Notes.  •SKIN MAY BE ABSORBED! Redness. Pain. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •EYES Redness. Blurred vision. Severe deep burns. Face shield. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. (Further see Inhalation). Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give plenty of water to drink. Refer for medical attention. See Notes. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Personal protection: complete protective clothing including self-contained breathing apparatus. Separated from strong oxidants, strong acids, food and feedstuffs . Ventilation along the floor. Do not transport with food and feedstuffs.

International Chemical Safety Cards ADIPONITRILE ICSC: 0211 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ODOURLESS, OILY, COLOURLESS LIQUID. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating or on burning producing highly toxic hydrogen cyanide (see ICSC 0492). Reacts violently with strong oxidants . OCCUPATIONAL EXPOSURE LIMITS: TLV: 2 ppm; 8.8 mg/m3 (as TWA) (skin) (ACGIH 1994-1995). OSHA PEL: none NIOSH REL: TWA 4 ppm (18 mg/m3) NIOSH IDLH: No data ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and through the skin, 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 irritates the eyes and the skin. Exposure could cause convulsions. Exposure may result in unconsciousness. Exposure may result in death. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the blood and adrenals , resulting in anaemia and tissue lesions . PHYSICAL PROPERTIES Boiling point: 295°C Melting point: 1°C Relative density (water = 1): 0.97 Solubility in water: moderate Vapour pressure, Pa at 20°C: 0.3 Relative vapour density (air = 1): 3.7 Flash point: 159°C c.c. (see Notes) Auto-ignition temperature: 550°C Explosive limits, vol% in air: 1.7-4.9 Octanol/water partition coefficient as log Pow: -0.32 ENVIRONMENTAL DATA N O T E S Upon poisoning by adiponitrile, specific first aid and treatment are essential. Consult a doctor. The flash point of adiponitrile, technical grade is 93°C (o.c.). Do NOT take working clothes home. Also consult ICSC 0492.
