Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: all extinguishing agents allowed. Explosion Exposure PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID Exposure OF ADOLESCENTS AND CHILDREN!  •Inhalation (See Ingestion). Ventilation (not if powder). Fresh air, rest. Refer for medical attention.  •Skin MAY BE ABSORBED! See Ingestion. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.  •Eyes Safety goggles, or face shield. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •Ingestion Convulsions. Dizziness. Headache. Nausea. Vomiting. Muscle twitching. Do not eat, drink, or smoke during work. Wash hands before eating. Give a slurry of activated charcoal in water to drink. Do NOT induce vomiting. Rest. Refer for medical attention. Spillage Disposal Storage Packaging & Labelling Do NOT wash away into sewer. Sweep spilled substance into sealable 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). Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs and incompatible materials: See Chemical Dangers. Well closed. Keep in a well-ventilated room. Store in an area without drain or sewer access. Do not transport with food and feedstuffs. Severe marine pollutant. T+ symbol N symbol R: 25-27-40-48/25-50/53 S: 1/2-22-36/37-45-60-61 UN Hazard Class: 6.1 UN Packing Group: II DIELDRIN ICSC: 0787 Important Data Physical State; Appearance: COLOURLESS CRYSTALS Physical Dangers: Chemical Dangers: The substance decomposes on heating producing toxic fumes including hydrogen chloride. Reacts with oxidants and acids. Attacks metal due to the slow formation of hydrogen chloride in storage. Occupational Exposure Limits: TLV (as TWA): 0.25 mg/m3, A4 (skin) (ACGIH 1997). MAK: (Inhalable fraction) 0.25 mg/m3 : Peak limitation category: II(8) skin absorption (H); (DFG 2007). OSHA PEL: TWA 0.25 mg/m3 skin NIOSH REL: Ca TWA 0.25 mg/m3 skin See Appendix A NIOSH IDLH: Ca 50 mg/m3 See: 60571 Routes of Exposure: The substance can be absorbed into the body 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 on spraying. Effects of Short-Term Exposure: The substance may cause effects on the central nervous system , resulting in convulsions. Medical observation is indicated. Effects of Long-Term or Repeated Exposure: The substance accumulates in the human body. Cumulative effects are possible: see Acute Hazards/Symptoms. Physical Properties Melting point: 175-176°C Density: 1.7 g/cm3 Solubility in water: none Vapour pressure, Pa at 20°C: 0.0004 Octanol/water partition coefficient as log Pow: 6.2 Environmental Data The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to honey bees, birds. In the food chain important to humans, bioaccumulation takes place, specifically in aquatic organisms. It is strongly advised not to let the chemical enter into the environment because it persists in the environment. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use. N O T E S Depending on the degree of exposure, periodic medical examination is indicated. If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s). Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Alvit, Dieldrex, Dieldrite, Illoxol, Octalox, Panoram, and Quintox are trade names. Also consult ICSC #0774, Aldrin. Transport Emergency Card: TEC (R)-61G41b.
