Gives off irritating or toxic fumes (or gases) in a fire. Heating will cause rise in pressure with risk of bursting. NO open flames. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Blue skin. Blue lips or finger nails. Dizziness. Headache. Nausea. Shortness of breath. Confusion. Convulsions. Unconsciousness. Local exhaust or breathing protection. Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.  •SKIN MAY BE ABSORBED! (Further see Inhalation). Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •EYES Redness. Pain. Blurred vision. Safety goggles, or 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. Give plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Remove all ignition sources. Do NOT wash away into sewer. Sweep spilled substance into containers. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. Chemical protection suit including self-contained breathing apparatus. Separated from strong oxidants, food and feedstuffs . Provision to contain effluent from fire extinguishing. Do not transport with food and feedstuffs. Marine pollutant.

International Chemical Safety Cards 3,4-DICHLOROANILINE ICSC: 0144 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: LIGHT-BROWN CRYSTALS , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes at 340°C on heating or on burning producing toxic fumes including nitrogen oxides , hydrogen chloride - see ICSC0163. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and 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. Exposure may result in death. The effects may be delayed. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the blood system , resulting in forming of methaemoglobin.
