Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.   EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID ALL CONTACT! INHALATION Blue lips or finger nails. Blue skin. Headache. Dizziness. Nausea. Confusion. Convulsions. Unconsciousness. Local exhaust or breathing protection. Fresh air, rest. Artificial respiration if indicated. Refer for medical attention. SKIN MAY BE ABSORBED! (see Inhalation). Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention. EYES Face shield. 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. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Consult an expert! Ventilation. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: chemical protection suit including self-contained breathing apparatus). Separated from strong bases, oxidants, reducing agents and food and feedstuffs. Well closed. Keep in a well-ventilated room. Do not transport with food and feedstuffs.

International Chemical Safety Cards 2,6-DINITROTOLUENE ICSC: 0728 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: YELLOW, BROWN TO RED CRYSTALS , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: May explode on heating. The substance decomposes on heating producing toxic and corrosive fumes including nitrogen oxides even in absence of air. Reacts with strong bases, oxidants and reducing agents. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV: ppm; 1.5 mg/m3 (as TWA) (skin) (ACGIH 1996). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. EFFECTS OF SHORT-TERM EXPOSURE: The substance may cause effects on the blood , resulting in the formation of methaemoglobin. The effects may be delayed. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the central nervous system, cardiovascular system and blood , resulting in formation of methaemoglobin. PHYSICAL PROPERTIES Boiling point: 285°C Melting point: 66°C Relative density (water = 1): 1.283 (liquid) Vapour pressure, Pa at 20°C: 2.4 Relative vapour density (air = 1): 6.28 Flash point: 207°C (c.c.)°C Octanol/water partition coefficient as log Pow: 2.050

ENVIRONMENTAL DATA
N O T E S
Use of alcoholic beverages enhances the harmful effect. Depending on the degree of exposure, periodic medical examination is indicated. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Also consult ICSC # 0465 on the isomer mixture.
