Many reactions may cause fire or explosion. See Notes. NO open flames. Water in large amounts. EXPLOSION Risk of fire and explosion. Do NOT expose to friction or shock. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.  •SKIN Redness. Yellow skin. Protective gloves. Protective clothing. Rinse and then wash skin with water and soap. Refer for medical attention.  •EYES Redness. Pain. Yellow vision. Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Headache. Dizziness. Nausea. Vomiting. Diarrhoea. Do not eat, drink, or smoke during work. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: P3 filter respirator for toxic particles). Fireproof. Separated from strong oxidants, metals and reducing substances. Special material. E symbol T symbol R: 2-4-23/24/25 S: 1/2-28-35-37-45 UN Hazard Class: 1.1 D SEE IMPORTANT INFORMATION ON BACK ICSC: 0316 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards PICRIC ACID ICSC: 0316 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: YELLOW CRYSTALS WITH NO ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: May explosively decompose on shock, friction, or concussion. May explode on heating. Shock-sensitive compounds are formed with metals, particularly copper, lead, mercury and zinc. On combustion, forms toxic carbon and nitrogen oxides. Reacts vigorously with oxidants and reducing materials. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.1 mg/m3 (as TWA) (ACGIH 1997). MAK: 0.1 mg/m3 I; H (1996). OSHA PEL: TWA 0.1 mg/m3 skin NIOSH REL: TWA 0.1 mg/m3 ST 0.3 mg/m3 skin NIOSH IDLH: 75 mg/m3 ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation 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 irritates the eyes, the skin and the respiratory tract. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. Skin and hair may be stained yellow. PHYSICAL PROPERTIES Melting point: 122°C Density: 1.8 g/cm3 Solubility in water, g/100 ml: 1.4 Relative vapour density (air = 1): 7.9 Flash point: 150°C Auto-ignition temperature: 300°C Octanol/water partition coefficient as log Pow: 2.03 ENVIRONMENTAL DATA N O T E S For safety transportation, 10-20% water is usually added. In normal conditions: combustible; if oxidized may become explosive. Do NOT take working clothes home. Rinse contaminated clothes (fire hazard) with plenty of water. Transport Emergency Card: TEC (R)-41G19 NFPA Code: H3; F4; R4; Other UN number is 1344, with not less than 30% water by mass, hazard class 4.1, packing group I.
