Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Alcohol-resistant foam, powder, carbon dioxide. EXPLOSION EXPOSURE PREVENT GENERATION OF MISTS! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN! IN ALL CASES CONSULT A DOCTOR!  •INHALATION (See Ingestion). Breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN MAY BE ABSORBED! Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. Safety goggles, or face shield, 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 Confusion. Convulsions. Nausea. Vomiting. Do not eat, drink, or smoke during work. Wash hands before eating. Rest. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer.

International Chemical Safety Cards CHLORDANE (TECHNICAL PRODUCT) ICSC: 0740 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: TECHNICAL: LIGHT YELLOW TO AMBER VISCOUS LIQUID PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on burning, on contact with bases producing toxic fumes including chlorine, phosgene, hydrogen chloride. Attacks iron, zinc, plastics, rubber and coatings. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.5 mg/m3 (as TWA), A3 (skin) (ACGIH 1997). OSHA PEL: TWA 0.5 mg/m3 skin NIOSH REL: Ca TWA 0.5 mg/m3 skin See Appendix A NIOSH IDLH: Potential occupational carcinogen 100 mg/m3 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 on spraying. EFFECTS OF SHORT-TERM EXPOSURE: Exposure at high levels may result in disorientation, tremors, convulsions, respiratory failure and death. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the liver and immune system , resulting in tissue lesions and liver impairment. This substance is possibly carcinogenic to humans. PHYSICAL PROPERTIES Boiling point at 0.27kPa: 175°C Relative density (water = 1): 1.59-1.63 Solubility in water: none Vapour pressure, Pa at 25°C: 0.0013 Octanol/water partition coefficient as log Pow: 2.78 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to soil organisms, bees. 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. N O T E S 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. Belt, Chlor Kil, Chlortox, Corodan, Gold Crest, Intox, Kypchlor, Niran, Octachlor, Sydane, Synklor, Termi-Ded, Topiclor, and Toxichlor are trade names. Also consult ICSC #0743 (Heptachlor).
