International Chemical Safety Cards TRICHLORONAPHTHALENE ICSC: 0962 TRICHLORONAPHTHALENE C10H5Cl3 Molecular mass: 231.5 CAS # 1321-65-9 RTECS # QK4025000 ICSC # 0962 UN # 2811 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Foam, powder, carbon dioxide. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE! INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest. SKIN Redness. Pain. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap. EYES Redness. Pain. Safety spectacles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. INGESTION Nausea. Vomiting. Do not eat, drink, or smoke during work. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment (extra personal protection: P2 filter respirator for harmful particles). Separated from strong oxidants, food and feedstuffs. Do not transport with food and feedstuffs. UN Hazard Class: 6.1 UN Packing Group: III SEE IMPORTANT INFORMATION ON BACK ICSC: 0962 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities © IPCS CEC 1993 No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and IDLH values.

International Chemical Safety Cards TRICHLORONAPHTHALENE ICSC: 0962 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS TO YELLOW SOLID IN VARIOUS FORMS , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on burning producing toxic and corrosive fumes including hydrogen chloride, phosgene. Reacts with strong oxidants causing fire hazard. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV: ppm; 5 mg/m3 (as TWA) (skin) (ACGIH 1996). MAK: ppm; 5 mg/m3 (skin) (ACGIH 1995). OSHA PEL: TWA 5 mg/m3 skin NIOSH REL: TWA 5 mg/m3 skin NIOSH IDLH: Unknown 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 nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes and the skin. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the liver , resulting in liver impairment. PHYSICAL PROPERTIES Boiling point: 304-354°C Melting point: 93°C Density: 1.58 Solubility in water: none Vapour pressure, Pa at 20°C: <133 Relative vapour density (air = 1): 8 Flash point: 200°C o.c. ENVIRONMENTAL DATA This substance may be hazardous to the environment; special attention should be given to crustacea. 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 because it persists in the environment. NOTES Halowax, Nibren wax and seekay wax are trade names.
