International Chemical Safety Cards OCTACHLORONAPHTHALENE ICSC: 1059 OCTACHLORONAPHTHALENE C10Cl8 Molecular mass: 403.7 CAS # 2234-13-1 RTECS # QK0250000 ICSC # 1059 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION   EXPOSURE STRICT HYGIENE! INHALATION Ventilation (not if powder), local exhaust, or 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. 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 Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers. Carefully collect remainder, then remove to safe place (extra personal protection: P3 filter respirator for toxic particles).

International Chemical Safety Cards OCTACHLORONAPHTHALENE ICSC: 1059 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: PALE-YELLOW, WAXY SOLID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes (chlorine). OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV: ppm; 0.1 mg/m3 (as TWA); 0.3 mg/m3 (as STEL) (skin) (ACGIH 1992-1993). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol, 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 by dispersion. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the liver , resulting in jaundice. PHYSICAL PROPERTIES Boiling point: 440°C Melting point: 192°C Relative density (water = 1): 2.0 Solubility in water: none Vapour pressure, kPa at 20°C: <0.13 Relative vapour density (air = 1): 13.9 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.01
