International Chemical Safety Cards 2-CHLOROANILINE ICSC: 0129 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS TO YELLOW LIQUID , WITH CHARACTERISTIC ODOUR. TURNS DARK ON EXPOSURE TO AIR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on burning producing toxic fumes including nitrogen oxides , hydrogen chloride - see ICSC0163. OCCUPATIONAL EXPOSURE LIMITS: TLV: BEI issued (ACGIH 2004). MAK: IIb (not established but data is available) skin absorption (H); (DFG 2004). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes . The substance may cause effects on the blood , resulting in the formation of methaemoglobin. Medical observation is indicated. The effects may be delayed. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the blood , resulting in formation of methaemoglobin.
