Kev cais pov tseg kom raug yog qhov tseem ceeb rau kev tiv thaiv pej xeem kev noj qab haus huv thiab ib puag ncig. Ntawm ntau hom pov tseg, cov khib nyiab pov tseg muaj kev pheej hmoo tshwj xeeb vim nws cov tshuaj lom, flammability, lossis reactivity. Cov ntaub ntawv zoo li no yuav tsum tau muab pov tseg rau hauv cov thawv pov tseg uas tsim kev puas tsuaj los tiv thaiv ib puag ncig kev sib kis thiab ua rau tib neeg thiab tsiaj txhu. Kev nkag siab txog yam khoom twg yuav tsum tau tuav tshwj xeeb no yog qhov tseem ceeb rau kev pov tseg pov tseg kom nyab xeeb thiab muaj lub luag haujlwm.
Cov pov tseg uas muaj kev phom sij suav nrog cov khoom uas tuaj yeem ua mob rau kev noj qab haus huv lossis ib puag ncig yog tias tswj tsis raug. Cov tshuaj no feem ntau yog tswj hwm los ntawm tsoomfwv cov koomhaum, xws li Lub Chaw Saib Xyuas Kev Tiv Thaiv Ib Cheeb Tsam (EPA) hauv Tebchaws Meskas, uas txhais cov khib nyiab pov tseg raws li plaub yam ntxwv: ignitability, corrosivity, reactivity, thiab toxicity.
Chemical Cleaners thiab Solvents
Cov khoom xws li cov xim pleev xim, degreasers, thiab cov tshuaj ntxuav tsev feem ntau muaj cov tshuaj phem. Yog tias muab pov tseg tsis raug, lawv tuaj yeem paug cov dej los yog tso pa tawm. Cov thawv pov tseg uas muaj kev phom sij kom ntseeg tau tias cov tshuaj no raug kho kom zoo.
Roj teeb
Cov roj teeb, tshwj xeeb tshaj yog cov rechargeable xws li lithium-ion thiab nickel-cadmium, muaj cov hlau hnyav xws li cadmium, txhuas, thiab mercury. Cov ntsiab lus no yog tshuaj lom thiab tuaj yeem nkag mus rau hauv av thiab dej hauv av yog tias muab pov tseg hauv cov thoob khib nyiab. Cov roj teeb hauv tsev me me thiab cov roj teeb tsheb zoo ib yam yuav tsum mus rau hauv kev pov tseg pov tseg.
Tshuaj tua kab thiab tshuaj tua kab mob
Cov tshuaj tua kab, tshuaj tua kab, thiab lwm yam tshuaj ua liaj ua teb muaj tshuaj lom heev rau tib neeg thiab tsiaj qus. Txawm tias qhov me me tuaj yeem ua rau lub cev tsis zoo, ua rau nws tseem ceeb rau kev pov tseg cov khoom no hauv cov thawv pov tseg.
Kho mob pov tseg
Qee hom kev kho mob pov tseg, xws li cov ntse ntse (cov koob thiab cov koob txhaj tshuaj), cov tshuaj siv tas sij hawm, thiab cov tshuaj chemical reagents, suav tias yog kev phom sij. Cov khoom no tuaj yeem kis tau kab mob lossis muaj cov khoom tsis zoo, yuav tsum tau ceev faj tuav thiab pov tseg.
Cov khoom siv hluav taws xob
Cov khoom siv hluav taws xob xws li roj av, roj av, thiab propane tanks ua rau muaj kev pheej hmoo ntawm hluav taws kub lossis tawg yog tias muab pov tseg tsis tu ncua. Cov ntaub ntawv no yuav tsum tau muab pov tseg rau hauv cov chaw tshwj xeeb pov tseg.
Cov Khoom Siv Hluav Taws Xob (E-Waste)
Cov khoom xws li cov xov tooj qub, khoos phis tawj, thiab TV feem ntau muaj cov khoom phom sij xws li txhuas, mercury, thiab arsenic. Cov tshuaj no tuaj yeem tawm mus thiab ua rau muaj kev puas tsuaj loj rau ib puag ncig, ua rau e-kua pov tseg yog qhov tseem ceeb rau kev pov tseg phom sij.
Xim thiab Varnishes
Roj-raws li xim, varnishes, thiab lwm yam khoom muaj teeb meem vim lawv cov tshuaj muaj pes tsawg leeg. Cov xim pleev xim rau dej yuav tsis yog ib txwm tsim nyog raws li kev phom sij tab sis tseem yuav tsum tau muab pov tseg ntawm lub luag haujlwm.
Kev pov tseg tsis raug ntawm cov khib nyiab pov tseg tuaj yeem ua rau muaj qhov tshwm sim loj heev, suav nrog:
Kev puas tsuaj ib puag ncig:Cov av, huab cua, thiab dej paug.
Kev phom sij rau kev noj qab haus huv:Kev nthuav tawm tib neeg thiab tsiaj txhu rau cov tshuaj lom neeg.
Kev nplua raws cai:Tsis ua raws li cov cai pov tseg pov tseg.
Cov khoom xws li cov tshuaj ntxuav tes, roj teeb, tshuaj tua kab, cov khib nyiab kho mob, cov nplaim hluav taws, e-kua pov tseg, thiab cov xim yuav tsum tau muab pov tseg rau hauv cov thawv pov tseg. Ua raws li kev coj ua pov tseg kom raug tsis yog tsuas yog ua kom muaj kev nyab xeeb ntawm tus kheej thiab pej xeem tab sis kuj tseem tiv thaiv ib puag ncig rau cov tiam tom ntej. Los ntawm kev nco qab txog kev tswj cov khoom pov tseg, peb tuaj yeem txo cov pa phem thiab txaus ntshai rau kev noj qab haus huv.
