International Chemical Safety Cards DINITRO-o-CRESOL ICSC: 0462 4,6-Dinitro-ortho-cresol 2-Methyl-4,6-dinitrophenol DNOC 2,4-Dinitro-ortho-cresol C7H6N2O5 / CH3C6H2OH(NO2)2 Molecular mass: 198.1 ICSC #    0462 CAS #     534-52-1 RTECS # GO9625000 UN #        1598 EC #         609-020-00-X April 19, 2004 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. NO contact with oxidants. Water spray, foam, dry powder, carbon dioxide. EXPLOSION Finely dispersed particles form explosive mixtures in air. Risk of fire and explosion on contact withoxidants. 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. EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE!  •INHALATION Sweating. Fever or elevated body temperature. Nausea. Shortness of breath. Laboured breathing. Headache. Convulsions. Unconsciousness. Local exhaust or breathing protection. Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.  •SKIN MAY BE ABSORBED! Yellow stain. (Further see Inhalation). Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. 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 Abdominal pain. Vomiting. (Further 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. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. Personal protection: chemical protection suit including self-contained breathing apparatus. Separated from strong oxidants, food and feed stuffs . Well closed. Do not transport with food and feedstuffs.

International Chemical Safety Cards DINITRO-o-CRESOL ICSC: 0462 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ODOURLESS , YELLOW CRYSTALS PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. CHEMICAL DANGERS: The substance decomposes on burning producing toxic fumes including nitrogen oxides. Reacts violently with strong oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.2 mg/m³ as TWA; (skin); (ACGIH 2004). MAK: IIb, see Notes; H; (DFG 2003). NIOSH REL: TWA 0.2 mg/m3 skin NIOSH IDLH: 5 mg/m3 ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. EFFECTS OF SHORT-TERM EXPOSURE: The substance is corrosive to the eyes and is irritating to the skin . Yellow staining of the skin. The substance may cause effects on the metabolic rate. Exposure at high levels may result in death. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 312°C Melting point: 87.5°C Density: 1.58 g/cm3 Solubility in water, g/100 ml at 20°C: 0.694 Vapour pressure, Pa at 25°C: 0.016 Relative vapour density (air = 1): 6.8 Auto-ignition temperature: 340°C Octanol/water partition coefficient as log Pow: 2.56 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. N O T E S Do NOT take working clothes home. Antinonnin, Detal, Dinitrol, Elgetol, Lipan, Selinon and Effusan are trade names. MAK not established but data is available. Technical grade may cause skin sensitization. Transport Emergency Card: TEC (R)-61S1598 or 61GT2-II ADDITIONAL INFORMATION ICSC: 0462 DINITRO-o-CRESOL (C) IPCS, CEC, 1994
