Hydroxyethyl methylcellulose (HEMC) ni polymer ikoreshwa cyane mu nganda zitandukanye, harimo imiti, ibiryo, amavuta yo kwisiga, nubwubatsi. Irashimirwa kubyimbye, kwigana, gukora firime, no gutuza ibintu. Nubwo ikoreshwa cyane, kurinda umutekano mugihe cyo kuyikoresha no kuyikoresha ni ngombwa. Dore ingamba zuzuye z'umutekano zo gukoresha hydroxyethyl methylcellulose:
1. Gusobanukirwa Ibikoresho
HEMC ni selile idafite ionic selile, ikomoka kuri selile aho amatsinda ya hydroxyl yasimbuwe igice hamwe na hydroxyethyl na methyl. Ihinduka ritezimbere gukemura no gukora. Kumenya imiterere yimiti niyumubiri, nko kwikemurira ibibazo, kwijimye, no gutuza, bifasha mugukemura neza.
2. Ibikoresho byawe bwite byo kurinda (PPE)
Uturindantoki n'imyambaro ikingira:
Wambare uturindantoki twirinda imiti kugirango wirinde uruhu.
Koresha imyenda ikingira, harimo amashati maremare n'amapantaro, kugirango wirinde uruhu.
Kurinda amaso:
Koresha indorerwamo z'umutekano cyangwa ingabo zo mu maso kugirango urinde umukungugu cyangwa imyanda.
Kurinda Ubuhumekero:
Niba ukoresha HEMC muburyo bwa poro, koresha masike yumukungugu cyangwa ubuhumekero kugirango wirinde guhumeka neza.
3. Gukoresha no Kubika
Guhumeka:
Menya neza ko umwuka uhagije ahakorerwa kugirango ugabanye ivumbi.
Koresha umuyaga uhumeka cyangwa ubundi bugenzuzi bwubuhanga kugirango ugumane ikirere kiri munsi yimipaka yagenewe.
Ububiko:
Bika HEMC ahantu hakonje, humye kure yubushyuhe nizuba ryizuba.
Komeza ibikoresho bifunze cyane kugirango wirinde kwanduza no gutwarwa nubushuhe.
Ubike kure y'ibintu bidahuye nka okiside ikomeye.
Gukemura ibibazo:
Irinde kurema umukungugu; witonze witonze.
Koresha tekinike ikwiye nko guhanagura cyangwa gukoresha umukungugu kugirango ugabanye ibice byo mu kirere.
Shyira mubikorwa uburyo bwiza bwo kubungabunga urugo kugirango wirinde ivumbi.
4. Gusuka no Kumeneka
Isuka rito:
Ihanagura cyangwa uhindure ibintu hanyuma ubishyire mubikoresho bikwiye.
Irinde guhanagura byumye kugirango wirinde ivumbi; koresha uburyo butose cyangwa HEPA-yungurujwe vacuum.
Isuka rikomeye:
Kwimura ako gace no guhumeka.
Wambare PPE ikwiye kandi urimo isuka kugirango wirinde gukwirakwira.
Koresha ibikoresho bya inert nkumucanga cyangwa vermiculite kugirango winjize ibintu.
Kujugunya ibikoresho byakusanyijwe ukurikije amabwiriza yaho.
5. Kugenzura Kumurika nisuku Yumuntu
Imipaka ntarengwa:
Kurikiza amabwiriza y’umutekano n’ubuzima (OSHA) cyangwa amabwiriza y’ibanze ajyanye n’imipaka igaragara.
Isuku y'umuntu ku giti cye:
Karaba intoki neza nyuma yo gufata HEMC, cyane cyane mbere yo kurya, kunywa, cyangwa kunywa itabi.
Irinde gukora mu maso hawe uturindantoki cyangwa amaboko yanduye.
6. Ibyago byubuzima ningamba zambere zifasha
Guhumeka:
Kumara igihe kinini umukungugu wa HEMC bishobora gutera uburakari.
Himura umuntu wanduye kumuyaga mwiza hanyuma ushakire kwa muganga niba ibimenyetso bikomeje.
Guhuza uruhu:
Karaba ahantu hafashwe n'isabune n'amazi.
Shakisha inama zubuvuzi niba uburakari butangiye.
Guhuza amaso:
Koza amaso neza n'amazi byibuze muminota 15.
Kuraho lens ya contact niba ihari kandi byoroshye gukora.
Shakisha ubuvuzi niba uburakari bukomeje.
Ingestion:
Koza umunwa n'amazi.
Ntugatera kuruka keretse iyobowe nabashinzwe ubuvuzi.
Shakisha ubuvuzi niba ari bwinshi.
7. Ibyago byumuriro no guturika
HEMC ntabwo yaka cyane ariko irashobora gutwikwa iyo ihuye numuriro.
Ingamba zo kurwanya umuriro:
Koresha spray yamazi, ifuro, imiti yumye, cyangwa dioxyde de carbone kugirango uzimye umuriro.
Wambare ibikoresho byose birinda, harimo ibikoresho byo guhumeka byonyine (SCBA), mugihe urwanya umuriro urimo HEMC.
Irinde gukoresha imigezi yumuvuduko mwinshi wamazi, ushobora gukwirakwiza umuriro.
8. Kwirinda ibidukikije
Irinde kurekura ibidukikije:
Irinde irekurwa rya HEMC mubidukikije, cyane cyane mumazi, kuko bishobora kugira ingaruka mubuzima bwamazi.
Kujugunya:
Kujugunya HEMC ukurikije amabwiriza y’ibanze, leta, na leta.
Ntusohore mu nzira y'amazi utabanje kuvurwa neza.
9. Amakuru agenga
Kwandika no gutondekanya:
Menya neza ko ibikoresho bya HEMC byanditse neza ukurikije ibipimo ngenderwaho.
Menyesha urupapuro rwumutekano (SDS) kandi ukurikize umurongo ngenderwaho.
Ubwikorezi:
Kurikiza amabwiriza yo gutwara HEMC, urebe ko kontineri zifunze kandi zifite umutekano.
10. Amahugurwa n'Uburere
Amahugurwa y'abakozi:
Tanga amahugurwa kubijyanye no gufata neza, kubika, no kujugunya HEMC.
Menya neza ko abakozi bazi ingaruka zishobora kubaho n'ingamba zikenewe.
Uburyo bwihutirwa:
Gutezimbere no kumenyekanisha uburyo bwihutirwa bwo kumeneka, kumeneka, no guhura.
Kora imyitozo isanzwe kugirango witegure.
11. Ibicuruzwa byihariye byo kwirinda
Ingaruka zihariye zo gushiraho:
Ukurikije uburyo hamwe na HEMC yibanze, ingamba zikenewe zirashobora gukenerwa.
Reba amabwiriza yihariye yibicuruzwa nibyifuzo byabayikoze.
Amabwiriza yihariye yo gusaba:
Muri farumasi, menya neza ko HEMC iri murwego rukwiye rwo gufata cyangwa gutera inshinge.
Mu bwubatsi, menya ivumbi ryakozwe mugihe cyo kuvanga no kubishyira mu bikorwa.
Mugukurikiza ingamba zo kwirinda umutekano, ingaruka zijyanye no gukoresha hydroxyethyl methylcellulose zirashobora kugabanuka cyane. Kugenzura ibidukikije bikora neza ntibirinda abakozi gusa ahubwo binakomeza ubusugire bwibicuruzwa nibidukikije.
