• AUFNAHMEWEGE

  Aufnahme in den Körper durch Inhalation der Rauche und über die Haut.

• INHALATIONSGEFAHREN

  Verdampfung bei 20°C vernachlässigbar; eine gesundheitsschädliche Partikelkonzentration in der Luft kann jedoch schnell erreicht werden.

• WIRKUNGEN BEI KURZZEITEXPOSITION

  WIRKUNGEN BEI KURZZEITEXPOSITION:
  Die Substanz reizt die Augenund die Haut.

• WIRKUNGEN NACH WIEDERHOLTER ODER LANGZEITEXPOSITION

  Wiederholter oder andauernder Hautkontakt kann Dermatitis (Chlorakne )hervorrufen. Möglich sind Auswirkungen auf die Leber mit nachfolgenden Leberschäden.

• LECKAGE

  Verschüttetes Material in abdichtbaren Behältern sammeln; falls erforderlich durch Anfeuchten Staubentwicklung verhindern. Reste sorgfältig sammeln. An sicheren Ort bringen. NICHT in die Umwelt gelangen lassen. Chemikalienschutzanzug. Persönliche Schutzausrüstung: Atemschutzgerät, P2-Filter für schädliche Partikel.

• Chemische Eigenschaften

  The chlorinated naphthalenes in which one or more hydrogen atoms have been replaced by chlorine to form wax-like substances, beginning with monochloronaphthalene and going on to the octachlor derivatives. Their physical states vary from mobile liquids to waxysolids depending on the degree of chlorination; freezing/ melting points of the pure compounds range from 17C for 1-chloronaphthalene to 198C for 1,2,3,4- tetrachloronaphthalene. 1-Chloro-isomer: Hazard identification (based on NFPA-704 M Rating System): Health 2, flammability 1, reactivity 0. 2-Chloro-isomer:

• Chemische Eigenschaften

  White solid.

• Verwenden

  In synthetic wax; in electric wire insulation; in lubricants

• Verwenden

  Hexachloronaphthalene is used in electricwire insulation and as an additive to lubri cants.

• Allgemeine Beschreibung

  White solid with an aromatic odor.

• Air & Water Reaktionen

  Insoluble in water.

• Reaktivität anzeigen

  HALOWAX 1014 is generally unreactive. May be incompatible with strong oxidizing and reducing agents. May be incompatible with some amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

• Hazard

  Toxic by inhalation, strong irritant, absorbed by skin.

• Health Hazard

  The symptoms of acute toxicity are chlo racne or an acneform of dermatitis, nausea,weakness, confusion, and jaundice. The tar get organs are mainly the liver and skin. Mix tures of penta- and hexachloronaphthaleneat concentrations between 1 and 2 mg/m³have been attributed to fatal cases of yel low atrophy of the liver (Elkins 1959). TheLD50 values for this compound are notreported.

• Brandgefahr

  Literature sources indicate that HALOWAX 1014 is nonflammable.

• mögliche Exposition

  Industrial exposure from individual chlorinated naphthalenes is rarely encountered; rather it usually occurs from mixtures of two or more Chlorinated naphthalenes. Due to their stability, thermoplasticity, and nonflammability, these compounds enjoy wide industrial application. These compounds are used in the production of electric condensers; in the insulation of electric cables and wires; as additives to extreme pressure lubricants; as supports for storage batteries; and as a coating in foundry use. octachloro-: Used as a fireproof and waterproof additive and lubricant additive. Pentachloro-: Used in electric wire insulation and in additives to special lubricants. tetrachloro-: Used in electrical insulating materials and as an additive in cutting oils. trichloro-: Used in lubricants and in the manufacture of insulation for electrical wire. Because of the possible potentiation of the toxicity of higher Chlorinated naphthalenes by ethanol and carbon tetrachloride, individuals who ingest enough alcohol to result in liver dysfunction would be a special group at risk. Individuals, e.g., analytical and synthetic chemists, mechanics and cleaners, who are routinely exposed to carbon tetrachloride or other hepatotoxic chemicals would also be at a greater risk than a population without such exposure. Individuals involved in the manufacture, utilization, or disposal of polychlorinated naphthalenes would be expected to have higher levels of exposure than the general population.

• Versand/Shipping

  UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

• Inkompatibilitäten

  All are incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Keep away from heat. Penta- is also incompatible with acids, alkalis.

• Waste disposal

  High-temperature incineration with flue gas scrubbing. Incineration, preferably after mixing with another combustible fuel. Care must be exercised to assure complete combustion to prevent the formation of phosgene. An acid scrubber is necessary to remove the halo acids produced.
