Tsis zoo li ib qho -size- haum- tag nrho cov iav, kev tiv thaiv lub ntsej muag zoo yuav tsum ua raws li kev ua haujlwm txaus ntshai-los ntawm cov khoom me me mus rau cov tshuaj lom neeg. Cov lus qhia no rhuav tshem cov ntsiab lus tseem ceeb thiab siv ob qhov tiag tiag -kev kho dua tshiab hauv ntiaj teb los piav qhia seb qhov kev xaiv ntaub thaiv npog yuav tiv thaiv cov neeg ua haujlwm li cas.
Cov ntaub thaiv npog ntsej muag tsis yog cov khoom siv ntxiv xwb; lawv tsim kev thaiv qhov muag thiab lub ntsej muag raug mob, uas suav txog 20% ntawm kev tsim kho-txog qhov xwm txheej. Cov yam tseem ceeb hauv kev xaiv muaj xws li hom phom sij (piv txwv, tshuaj lom neeg, kev cuam tshuam), cov ntaub thaiv npog, thiab kev sib raug zoo nrog lwm yam PPE (lub tshuab ua pa, tsom iav). Lub teeb yuag, kev xaiv ruaj khov txhawb kev ua raws, raws li cov neeg cog lus hnav lawv rau kev ua haujlwm ntev. Hauv qab no yog ob qho kev kho dua tshiab thiab lawv cov kev daws teeb meem zoo tshaj plaws.
Case 1: Drywall Renovation & Sanding
Ib pab neeg ua haujlwm tau raug ntiav los kho lub tsev xyoo 1920s sab hauv, suav nrog kev tshem tawm phab ntsa ntub dej, xuab zeb, thiab patching. Txoj haujlwm tsim cov huab ntom ntom ntawm cov hmoov av zoo gypsum, sib xyaw nrog cov kab fiberglass los ntawm cov rwb thaiv tsev qub. Thaum xub thawj, cov neeg ua haujlwm tau siv cov tsom iav tsom iav yooj yim, tab sis cov khoom siv plua plav tseem ua rau lawv lub qhov muag khaus thiab nyob ntawm daim tawv nqaij ntawm lub ntsej muag, ua rau khaus thiab khaus.
Txoj kev daws teeb meem: Hloov mus rau cov ntaub thaiv npog polycarbonate ua ke nrog N95 lub tshuab ua pa. Cov ntaub thaiv npog no muaj tag nrho - lub ntsej muag tsim uas thaiv cov plua plav tawm ntawm txhua lub ces kaum, tsis zoo li cov tsom iav uas tawm qhov khoob ntawm ob sab plhu. Cov khoom siv polycarbonate yog khawb- tiv taus- tseem ceeb rau kev ua haujlwm xuab zeb uas cov khib nyiab tuaj yeem ya tau - thiab hnyav txaus rau 8 - teev hnav. Tom qab hloov pauv, tsis muaj neeg ua haujlwm qhia qhov muag khaus, thiab lub sijhawm ntxuav tau txo qis vim cov plua plav tau khaws cia ntawm daim tawv nqaij thiab khaub ncaws.
Case 2: Chav ua noj txee Refinishing
Lwm pab neeg tackled refinishing chav ua noj txee, uas yuav tsum tau stripping qub xim nrog methylene chloride-raws li tshem tawm thiab siv dej-raws li polyurethane. Cov txheej txheem stripping ua rau cov pa corrosive thiab qee zaus cov kua splatters, thaum daim ntawv thov polyurethane tso tawm VOCs. Cov neeg ua haujlwm thawj zaug siv cov ntaub thaiv npog yas, tab sis cov pa taws nkag hauv qab daim thaiv ntug, thiab cov xim tshem tawm cov splatters puas cov yas, txo qhov pom.
Txoj kev daws teeb meem: Kev kho dua tshiab rau tshuaj lom neeg- tiv taus puv - lub ntsej muag tiv thaiv nrog neoprene headbands. Cov ntaub thaiv npog no yog ua los ntawm cov tshuaj lom neeg - qib polycarbonate uas tiv thaiv kev degradation los ntawm cov kuab tshuaj thiab cov tshuaj tshem tawm. Lub neoprene headband tsim lub kaw ntom nti tiv thaiv lub hauv pliaj, thaiv cov fume infiltration. Lawv kuj ua khub seamlessly nrog cov tshuaj tua kab mob ua pa, ua kom muaj kev tiv thaiv lub ntsej muag thiab ua pa.

Rau cov neeg cog lus, txoj cai golden yog: phim cov ntaub thaiv npog rau qhov phom sij. Particulate -cov hauj lwm hnyav thov khawb- tiv taus, puv - ntsej muag polycarbonate shields, thaum cov dej num tshuaj yuav tsum muaj tshuaj lom neeg - cov qauv tiv taus nrog cov ntsaws ruaj ruaj. Kev nqis peev hauv txoj haujlwm- cov ntaub thaiv tshwj xeeb txo qis kev raug mob thiab ua kom cov haujlwm ua haujlwm.
