Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Water spray, carbon dioxide, foam, powder . EXPLOSION Above 96°C explosive vapour/air mixtures may be formed. Above 96°C use a closed system, ventilation. EXPOSURE AVOID ALL CONTACT!  •INHALATION Blue lips or finger nails. Dizziness. Headache. Nausea. Confusion. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.  •SKIN MAY BE ABSORBED! Redness. Pain. (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. Safety goggles, 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 (See Inhalation). Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Give a slurry of activated charcoal in water to drink. Rest. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment. Personal protection: filter respirator for organic gases and vapours. Chemical protection suit. Well closed. Separated from strong oxidants, hypochlorites , food and feedstuffs . Do not transport with food and feedstuffs.

International Chemical Safety Cards 2,6-XYLIDINE ICSC: 1519 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: YELLOW LIQUID , WITH CHARACTERISTIC ODOUR. TURNS BROWN ON EXPOSURE TO AIR. PHYSICAL DANGERS: The vapour is heavier than air. CHEMICAL DANGERS: The substance decomposes on burning producing toxic and corrosive fumes. Reacts violently with strong oxidants. Reacts with hypochlorites forming explosive chloroamines. Attacks plastic and rubber. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK: H; Carcinogen category: 2; (DFG 2003). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air can be reached rather quickly 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 . Exposure at high levels may result in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: This substance is possibly carcinogenic to humans. The substance may have effects on the blood , resulting in anaemia . PHYSICAL PROPERTIES Boiling point: 216°C Melting point: 11.2°C Relative density (water = 1): 0.98 Solubility in water, g/100 ml at 20°C: 0.7 Vapour pressure, kPa at 20°C: 0.02 Relative vapour density (air = 1): 4.2 Flash point: 96°C Auto-ignition temperature: 520°C Explosive limits, vol% in air: 1.3-6.9 Octanol/water partition coefficient as log Pow: 1.84 ENVIRONMENTAL DATA The substance is harmful to aquatic organisms. N O T E S Do NOT take working clothes home. Depending on the degree of exposure, periodic medical examination is suggested. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. See ICSC 0600 Xylidine (mixed isomers).
