Ntim thiab khaws cia rau hauv qhov cua, ib puag ncig qhuav.
1. Thawv:Khw Dedc nyob rau hauv airtight ntim ua los ntawm cov khoom siv tau tshaj (xws li iav lossis qee yam plastics) kom tiv thaiv kom tsis huv thiab kev ua tsis taus.
2. Kub:Khaws lub thawv ntim rau hauv qhov chaw txias, qhuav qhov chaw kom deb ntawm kev tshav ntuj ncaj qha thiab kub. Nws yog qhov zoo tshaj plaws los khaws nws ntawm chav tsev kub lossis hauv tub yees, nyob ntawm cov chaw tsim khoom cov lus pom zoo.
3. Cov av noo:Nco ntsoov tias qhov chaw cia khoom yog noo noo tuaj yeem cuam tshuam rau kev ruaj ntseg ntawm lub compound.
4. Sau npe:Daim ntawv sau kom meej meej nrog cov npe siv tshuaj, kev xav, cov ntaub ntawv muaj kev phom sij, thiab tau txais hnub kom paub meej tias yog tus kheej thiab tuav.
5. Kev nyab xeeb ceev faj:Txav deb ntawm cov tshuaj tsis sib xws xws li muaj zog oxidizing cov neeg sawv cev lossis hauv paus. Xyuas kom meej tias qhov chaw cia khoom yog muaj cua zoo thiab nruab nrog cov cuab yeej tsim kev nyab xeeb xws li cov chaw nres nkoj tsim nyog thiab chaw da dej.
6. Kev Nkag Mus:Txwv tsis pub nkag mus rau thaj chaw cia khoom tsuas yog cov neeg ua haujlwm uas nkag siab txog cov phom sij cuam tshuam nrog cov tshuaj lom neeg.
Kev cai ua raws cai:Xyuas kom meej tias cov zaub mov xa tuaj ua raws li cov kev tswj hwm hauv zej zog, thiab thoob ntiaj teb cov cai hais txog cov khoom tsim kev puas tsuaj. Qhov no yuav suav nrog cov lus qhia raws li cov lus qhia raws li xws li Lub Chaw Haujlwm Thauj Mus Los (DOT) lossis International Huab Cua Kev Koom Tes (Iiata).
Ntim:Siv ntim khoom uas tsim nyog nrog cov tshuaj. Lub khob ntim yuav tsum muaj zog, cov khoom lag luam, thiab cim tau nrog cov cim tshuaj lom neeg, cim kev phom sij, thiab daws cov lus qhia.
Daim ntawv lo:Ua kom tag nrho cov khoom ntim tau muaj cov ntawv ceeb toom ceeb toom kev phom sij, suav nrog cov ntawv qhia txog kev nyab xeeb cov ntaub ntawv, los qhia cov kev pheej hmoo ntawm cov kev pheej hmoo txaus ntshai cuam tshuam nrog cov tshuaj.
Tswj kub:Saib xyuas qhov ntsuas kub kom zoo thaum lub sijhawm thauj mus los tiv thaiv kev ua kom tsis txhob muaj kev cuam tshuam lossis cov tshuaj tiv thaiv. Zam kev ua kom sov siab dua lossis lub hnub ci ncaj qha.
Zam cov ntaub ntawv tsis sib xws:Xyuas kom meej tias Dedc tsis tau xa ua ke nrog cov khoom siv tsis sib xws xws li cov oxidants muaj zog lossis cov hauv paus ua rau cov no muaj kev phom sij.
Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE):Cov neeg ua haujlwm koom nrog hauv kev thauj mus los yuav tsum hnav cov hnab looj tes tsim nyog, suav nrog hnab looj tes, hnab looj tes, thiab cov khaub ncaws tiv thaiv kom txo qis kev pheej hmoo ntawm kev phom sij.
Cov Txheej Txheem Ceev:Muaj cov txheej txheem xwm ceev nyob rau hauv rooj plaub ntawm spill lossis huam yuaj thaum thauj khoom. Qhov no suav nrog muaj cov khoom siv tshuaj thiab cov khoom siv ua ntej npaj.
Kev Kawm:Nco ntsoov tias txhua tus neeg ua haujlwm koom nrog tuav thiab thauj Dedc yog kev kawm txaus nyob hauv cov txheej txheem kev nyab xeeb thiab cov lus teb muaj xwm txheej ceev.
TOXICITY:Dedc tuaj yeem tsim kev puas tsuaj yog noj, nqus tau, lossis nqus tau ntawm daim tawv nqaij. Nws yog khaus rau daim tawv nqaij, ob lub qhov muag, thiab ua pa rau kev ua pa.
Carcinogenicity:Txawm hais tias cov ntaub ntawv tshwj xeeb ntawm cov carcinogenicity ntawm Dedc yuav tsis tau sau zoo, muaj ntau chlorinated tebchaw muaj cov peev xwm carcinogenic. Nws raug nquahu tias lawv raug txiav txim siab tshuaj yeeb dej caw.
Lub siab:Qee tus neeg yuav ntsib kev ua xua lossis rhiab tom qab hu rau Dedc, uas tau ua pob lossis teeb meem ua pa.
Kev Ceev Fwm Kev Nyab Xeeb:Thaum ua haujlwm nrog Dedc, Tsim Nyog Cov Khoom Siv Kev Tiv Thaiv Tus Kheej (PPE), xws li hnab looj tes, khawm, yuav tsum siv los txo kev raug.
Daim Ntawv Kev Nyab Xeeb (SDS):Nco ntsoov hais txog cov ntaub ntawv ntaub ntawv nyab xeeb rau 4,4-hydroxybisBisBisBisBisBisBisBenal ntsuas, thiab cov txheej txheem pab kev pabcuam nyab xeeb yog tias muaj kev sib kis.
