    IZIMPAHLA ZAMAKHEMIkhali

    I-Benzene iwuketshezi olucacile, oluguquguqukayo, olungenambala, oluvutha kakhulu olunephunga elimnandi, eliyisici.I-hydrocarbon enephunga elimnandi ebilisa ku-80.1 DC.I-Benzene isetshenziswa njenge-solvent ezindaweni eziningi zezimboni, njengokukhiqiza irabha nezicathulo, nasekukhiqizeni ezinye izinto ezibalulekile, njenge-styrene, phenol, ne-cyclohexane.Ibalulekile ekwenzeni izinto zokuhlanza, izibulala-zinambuzane, izincibilikisi nezikhipha upende.Ikhona emafutheni afana nophethiloli aze afike ezingeni lika-5%.

    Uketshezi lwamanzi olucacile, olungenambala ukuya kokuphuzi olunephunga elimnandi, olunamafuel, ama-phenolic noma iphunga elifana nelikaphethiloli.Ku-40 ° C, ukuhlushwa komkhawulo wephunga ongu-190 μg/L emoyeni kwanqunywa ngu-Young et al.(1996).Umkhawulo wephunga we-4.68 ppmv unqunywe nguLeonardos et al.(1969).Ukuhlushwa kwephunga lokuthola okungu-108 mg/m3 (34 ppmv) kubikwe ngu-Punter (1983).Isilinganiso esincane esincane esibonakalayo sephunga lokugxila emanzini ku-60 °C nasemoyeni ongu-40 °C kube ngu-0.072 kanye no-0.5 mg/L, ngokulandelanayo.

    I-Benzene iphinde iguqulwe ibe yi-cyclohexane, esetshenziselwa ukukhiqiza inayiloni nemicu yokwenziwa.

    I-Benzene yenzeka emikhiqizweni yokucwiliswa kwamalahle kanye nethayela lamalahle nasemikhiqizweni kaphethiloli efana nophethiloli.Iphinde itholakale emagesini nasezintubeni zokulahlwa kwemfucumfucu yezimboni, imfucumfucu yokwakha, kanye nemfucumfucu yokwakheka komhlaba (i-Oak Ridge National Laboratory 1989).Amanani amancane e-benzene, i-toluene, i-xylenes, nezinye izinto eziphilayo eziguquguqukayo atholwe enhlabathini nasemanzini angaphansi komhlaba eduze kwama-sanitarylandfill amaningi (US EPA 1989a,b).UKramer(1989) uhlole izinga le-exposuresto benzene ngesikhathi sokususwa, ukuhlanza, ukupompa, nokuhlolwa kwamathangi okugcina uphethiloli angaphansi komhlaba.Isilinganiso sokuchayeka komuntu singu-0.43–3.84 ppm (emahoreni angu-1.5–6) kanye nokuchayeka okuphezulu kakhulu kwesikhathi esifushane (imizuzu eyi-15) kwaba ngu-9.14 ppm.I-Benzene nayo ivela kugwayi (Hoffmann et al. 1989);ngaleyo ndlela ingozi yokuchayeka kwayo ingase ikhule ekuhogeleni intuthu enjalo.
    I-Benzene isetshenziswa njenge-solvent yama-wax, ama-resin, namafutha;njengesisusa sopende;njenge-diluentfor lacquers;ekwakhiweni kodayi, imithi, ivanishi, ne-linoleum; nanjengento engavuthiwe yokukhiqiza inani lezinto eziphilayo.

    UTHENGA KANJANI KITHI

    I-Chemwin ingahlinzeka ngenqwaba yama-hydrocarbon amaningi nezincibilikisi zamakhemikhali kumakhasimende ezimboni.Ngaphambi kwalokho, sicela ufunde ulwazi olulandelayo oluyisisekelo mayelana nokwenza ibhizinisi nathi: 

    1. Ezokuphepha

    Ukuphepha kuyinto ehamba phambili yethu.Ngaphezu kokunikeza amakhasimende ulwazi mayelana nokusetshenziswa okuphephile nokunobungani kwemvelo kwemikhiqizo yethu, siphinde sizibophezele ekuqinisekiseni ukuthi ubungozi bokuphepha kwabasebenzi nosonkontileka buncishiswa bube buncane obunengqondo nobunokwenzeka.Ngakho-ke, sidinga ukuthi ikhasimende liqinisekise ukuthi izindinganiso ezifanele zokuphepha zokuthulula nokugcina impahla ziyahlangatshezwa ngaphambi kokulethwa kwethu (sicela ubheke isithasiselo se-HSSE emigomeni nemibandela yokuthengisa ngezansi).Ochwepheshe bethu be-HSSE banganikeza isiqondiso kulawa mazinga.

    2. Indlela yokulethwa

    Amakhasimende anga-oda futhi alethe imikhiqizo evela ku-chemwin, noma angathola imikhiqizo evela embonini yethu yokukhiqiza.Izindlela zokuthutha ezitholakalayo zifaka phakathi iloli, ujantshi noma ezokuthutha ezinezinhlobo eziningi (kuyasebenza izimo ezihlukene).

    Endabeni yezidingo zekhasimende, singacacisa izidingo zezikebhe noma amathangi futhi sisebenzise amazinga akhethekile okuphepha/wokubuyekeza kanye nezimfuneko.

    3. Inani elincane le-oda

    Uma uthenga imikhiqizo kuwebhusayithi yethu, inani elincane le-oda amathani angama-30.

    4.Inkokhelo

    Indlela yokukhokha ejwayelekile idonswa ngokuqondile zingakapheli izinsuku ezingu-30 ukusuka ku-invoyisi.

    5. Amadokhumenti okulethwa

    Amadokhumenti alandelayo anikezwa ngokudiliva ngakunye:

    · I-Bill of Lading, i-CMR Waybill noma enye incwadi yezokuthutha efanele

    · Isitifiketi Sokuhlaziya noma Ukuvumelana (uma sidingeka)

    · Imibhalo ehlobene ne-HSSE ngokuhambisana nemithethonqubo

    · Imibhalo yeCustoms ngokuhambisana nemithethonqubo (uma kudingeka)
