Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION EXPOSURE PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF (PREGNANT) WOMEN!  •INHALATION Drowsiness. Headache. Nausea. Unconsciousness. Ventilation. Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.  •SKIN MAY BE ABSORBED! Redness. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower.  •EYES Redness. 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. (See Inhalation). Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Rest. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking and spilled liquid in sealable steel (not copper) containers as far as possible. Wash away spilled liquid with plenty of water. Separated from oxidants . Dry.

International Chemical Safety Cards FORMAMIDE ICSC: 0891 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS, HYGROSCOPIC, VISCOUS LIQUID. PHYSICAL DANGERS: CHEMICAL DANGERS: On combustion, forms toxic gases (nitrogen oxides). The substance decomposes on heating at 180°C producing ammonia , water , carbon monoxide and hydrogen cyanide . Reacts withoxidants. Attacks metals such as aluminium, iron, copper and natural rubber. OCCUPATIONAL EXPOSURE LIMITS: TLV: 10 ppm as TWA; (skin); (ACGIH 2004). OSHA PEL: none NIOSH REL: TWA 10 ppm (15 mg/m3) skin NIOSH IDLH: No data ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour, 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 is irritating to the eyes and the skin . The substance may cause effects on the central nervous system . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Animal tests show that this substance possibly causes toxic effects upon human reproduction. PHYSICAL PROPERTIES Boiling point (decomposes): 210°C Melting point: 2.5°C Relative density (water = 1): 1.13 Solubility in water: very good Vapour pressure, Pa at 20°C: about 2 Relative vapour density (air = 1): 1.6 Flash point: 154°C o.c. Auto-ignition temperature: >500°C ENVIRONMENTAL DATA N O T E S Depending on the degree of exposure, periodic medical examination is suggested. Card has been partly updated in October 2004.
