International Chemical Safety Cards LINDANE ICSC: 0053 LINDANE gamma-1,2,3,4,5,6-Hexachlorocyclohexane gamma-BHC gamma-HCH C6H6Cl6 Molecular mass: 290.8 CAS # 58-89-9 RTECS # GV4900000 ICSC # 0053 UN # 2761 EC # 602-043-00-6 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible. 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 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! INHALATION Convulsions. Cough. Dizziness. Headache. Nausea. Weakness. Tremors. Paresthesias. Symptoms may be delayed (see Notes). Avoid inhalation of fine dust and mist. Local exhaust or breathing protection. Fresh air, rest. Artificial respiration if indicated. Refer for medical attention. SKIN MAY BE ABSORBED! Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention. Wear protective gloves when administering first aid. EYES Redness. 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 Abdominal pain. Diarrhoea (further see Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Give a slurry of activated charcoal in water to drink. Do NOT induce vomiting. Give plenty of water to drink. Rest. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Do NOT wash away into sewer. Sweep spilled substance into non-metallic sealable containers, then remove to safe place (extra personal protection: P3 filter respirator for toxic particles). Provision to contain effluent from fire extinguishing. Separated from bases, food and feedstuffs and metals. Do not transport with food and feedstuffs.

International Chemical Safety Cards LINDANE ICSC: 0053 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: ODOURLESS, WHITE CRYSTALLINE POWDER. CHEMICAL DANGERS: On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive fumes including phosgene and hydrogen chloride. The substance decomposes on contact with alkalis producing trichlorobenzene, or on contact with powdered iron, aluminum and zinc. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV: ppm; 0.5 mg/m3 (as TWA) (skin) (ACGIH 1994-1995). MAK: ppm; 0.5 mg/m3; skin (1992). 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 when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes and the respiratory tract. The substance may cause effects on the central nervous system , resulting in convulsions and respiratory failure and collapse. Exposure may result in death. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the liver and kidneys. PHYSICAL PROPERTIES Boiling point: 323°C Melting point: 113°C Relative density (water = 1): 1.87 Solubility in water: none Vapour pressure, Pa at 20°C: 0.0012 Octanol/water partition coefficient as log Pow: 3.61- 3.72

ENVIRONMENTAL DATA	The substance is very toxic to aquatic organisms. In the food chain important to humans, bioaccumulation takes place, specifically in fish. It is strongly advised not to let the chemical enter into the environment, especially in soil, because it persists in the environment. &FIG13
N O T E S
Depending on the degree of exposure, periodic medical examination is indicated. Carrier solvents used in commercial formulations may change physical and toxicological properties. The relation between odour and the occupational exposure limit cannot be indicated. Do NOT take working clothes home. Gammexane, Tri-6, Lindafor, Lindatox, Agrocide, Isotox, Esoderm, Aparasin are trade names. Transport Emergency Card: TEC (R)-61G53c NFPA Code: H2; F0; R0
