    UMUTUNGO WA CHIMIQUE

    Benzene ni ibintu bisobanutse, bihindagurika, bidafite ibara, byaka cyane bifite impumuro nziza, iranga.Ni hydrocarubone nziza cyane itetse kuri 80.1 DC.Benzene ikoreshwa nk'umuti mu bice byinshi by'inganda, nko gukora reberi n'inkweto, no mu gukora ibindi bintu by'ingenzi, nka styrene, fenol, na cyclohexane.Nibyingenzi mugukora ibikoresho byo kwisiga, imiti yica udukoko, imiti, hamwe no kuvanaho amarangi.Iraboneka mu bicanwa nka lisansi kugeza kurwego rwa 5%.

    Amazi meza, adafite ibara ryoroshye ryumuhondo wamazi afite impumuro nziza, yuzuye, fenolike cyangwa umunuko umeze nka lisansi.Kuri 40 ° C, impumuro nziza ya 190 μg / L mu kirere yagenwe na Young n'abandi.(1996).Impumuro ya 4.68 ppmv yagenwe na Leonardos n'abandi.(1969).Punter (1983) yavuzeko impumuro nziza ya 108 mg / m3 (34 ppmv).Impuzandengo ya impumuro ntarengwa ishobora kugaragara mu mazi kuri 60 ° C no mu kirere kuri 40 ° C yari 0.072 na 0.5 mg / L.

    Benzene nayo ihindurwamo cyclohexane, ikoreshwa mu gukora fibre nylon.

    Benzene iboneka mu makara y’amakara n’amakara no mu bicuruzwa bya peteroli suchas lisansi.Iraboneka kandi muri gaze hamwe nubutaka bwimyanda y’imyanda y’inganda, imyanda yo kubaka, hamwe n’imyanda nyaburanga (Oak Ridge National Laboratory 1989).Umubare wa benzene, toluene, xylenes, hamwe n’ibindi binyabuzima bihindagurika byavumbuwe mu butaka n’amazi y’ubutaka hafi y’imyanda myinshi y’isuku (US EPA 1989a, b).Kramer (1989) yasuzumye urugero rwa benzene yerekanwe mugihe cyo kuyikuramo, kuyisukura, kuyivoma, no kuyipima ububiko bwa lisansi yo munsi.Ugereranyije abantu bahuye na 0.43–3.84 ppm (mumasaha 1.5-6) ​​kandi igihe gito cyane (15 - iminota) cyagaragaye cyari 9.14 ppm.Benzene iboneka no mu itabi (Hoffmann et al. 1989);bityo ibyago byo guhura nabyo birashobora kwiyongera biturutse kumyotsi ihumeka.
    Benzene ikoreshwa nkigishishwa cyibishashara, ibisigazwa, namavuta;nk'ikuraho irangi;nk'ururimi rworoshye;mugukora amarangi, imiti, varike, na linini; kandi nkibikoresho fatizo byo kubyara ibinyabuzima byinshi.

    UBURYO BWO KUGURA

    Chemwin irashobora gutanga ibintu byinshi bya hydrocarbone hamwe nu muti wa chimique kubakiriya binganda.Mbere yibyo, nyamuneka soma amakuru y'ibanze akurikira yerekeye gukora ubucuruzi natwe: 

    1. Umutekano

    Umutekano nicyo dushyira imbere.Usibye guha abakiriya amakuru ajyanye no gukoresha ibicuruzwa byacu neza kandi bitangiza ibidukikije, twiyemeje kandi ko umutekano w’abakozi n’aba rwiyemezamirimo wagabanuka kugeza ku gipimo cyiza kandi gishoboka.Kubwibyo, turasaba abakiriya kwemeza ko ibipimo bikwiye byo gupakurura no kubika ibicuruzwa byujujwe mbere yo gutanga (nyamuneka reba umugereka wa HSSE mumagambo rusange nuburyo bwo kugurisha hepfo).Impuguke zacu HSSE zirashobora gutanga ubuyobozi kuri aya mahame.

    2. Uburyo bwo gutanga

    Abakiriya barashobora gutumiza no gutanga ibicuruzwa biva muri chemwin, cyangwa barashobora kwakira ibicuruzwa biva muruganda rwacu rukora.Uburyo buboneka bwubwikorezi burimo amakamyo, gari ya moshi cyangwa ubwikorezi butandukanye (ibintu bitandukanye birakurikizwa).

    Mugihe cyibisabwa abakiriya, turashobora kwerekana ibisabwa bya barge cyangwa tanker hanyuma tugashyiraho umutekano wihariye / gusuzuma ibipimo nibisabwa.

    3. Umubare ntarengwa wateganijwe

    Niba uguze ibicuruzwa kurubuga rwacu, umubare ntarengwa wateganijwe ni toni 30.

    4. Kwishura

    Uburyo busanzwe bwo kwishyura ni kugabanywa bitarenze iminsi 30 uhereye kuri fagitire.

    5. Inyandiko zitangwa

    Inyandiko zikurikira zitangwa na buri gutangwa:

    · Umushinga w'itegeko, CMR Waybill cyangwa izindi nyandiko zijyanye no gutwara abantu

    · Icyemezo cyo gusesengura cyangwa guhuza (niba bikenewe)

    · Inyandiko zijyanye na HSSE zijyanye n'amabwiriza

    · Inyandiko za gasutamo zijyanye n'amabwiriza (niba bikenewe)
