Thaum cov roj injector ntawm lub tshuab hluav taws xob tsis ua haujlwm, cov neeg ua haujlwm tu yuav tsum ua "4-R" ua haujlwm ntawm ntau qhov chaw ua tsis tau, uas yog, rhuav tshem, kho, kho, hloov kho, thiab hloov 4 txheej txheem. Yog hais tias qhov kev ua tau zoo ntawm cov twj tso kua mis yog qhov nyuaj kom ua tau raws li qhov yuav tsum tau ua, nws yog ib qho tsim nyog yuav tsum tau txais ib txoj kev daws teeb meem thiab kev tshawb fawb kom pom tseeb qhov laj thawj ntawm qhov ua tsis tiav thiab tsim cov kev daws teeb meem zoo.
