International Chemical Safety Cards DDT ICSC: 0034 DDT Dichlorodiphenyltrichloroethane 1,1,1-Trichloro-2,2-bis(p-chlorophenyl)ethane 2,2-bis(p-Chlorophenyl)-1,1,1-trichloroethane C14H9Cl5 Molecular mass: 354.5 CAS # 50-29-3 RTECS # KJ3325000 ICSC # 0034 UN # 2761 EC # 602-045-00-7 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Powder, water spray, foam, carbon dioxide. EXPLOSION Risk of fire and explosion if formulations contain flammable/explosive solvents. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR! INHALATION Cough. Avoid inhalation of fine dust and mist. Local exhaust or breathing protection. Fresh air, rest. Artificial respiration if indicated. Refer for medical attention. SKIN Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap. EYES Safety goggles, or eye protection in combination with breathing protection if powder. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. INGESTION Tremors. Convulsions. Diarrhoea. Dizziness. Vomiting. Numbness. Paresthesias. Hyperexcitability. Do not eat, drink, or smoke during work. Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Do NOT wash away into sewer. Sweep spilled substance into sealable non-metallic 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). Provision to contain effluent from fire extinguishing. Separated from strong bases, iron, aluminum and its salts, food and feedstuffs. Do not transport with food and feedstuffs. Do NOT keep in iron or aluminum containers.

International Chemical Safety Cards DDT ICSC: 0034 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS CRYSTALS OR WHITE POWDER. PHYSICAL DANGERS: CHEMICAL DANGERS: On combustion, forms toxic and corrosive fumes including hydrogen chloride. Reacts with organic and inorganic bases, aluminum, iron. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV: ppm; 1 mg/m3 (as TWA) (ACGIH 1993-1994). OSHA PEL: TWA 1 mg/m3 skin NIOSH REL: Ca TWA 0.5 mg/m3 See Appendix A NIOSH IDLH: Potential occupational carcinogen 500 mg/m3 ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and 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 especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system , resulting in convulsions and respiratory failure. Exposure may result in death. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the central nervous system, liver. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction. PHYSICAL PROPERTIES Boiling point: 260°C Melting point: 109°C Relative density (water = 1): 1.5 Solubility in water: none Octanol/water partition coefficient as log Pow: 6.36-6.38 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to birds. In the food chain important to humans, bioaccumulation takes place, specifically in milk and aquatic organisms. N O T E S Explosive limits are unknown in literature. Depending on the degree of exposure, periodic medical examination is indicated. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Agritan, Azotox, Anofex, Ixodex, Gesapon, Gesarex, Gesarol, Guesapon, and Neocid are trade names.
