Txhim kho cov khoom sib txhuam
Tom qab ntau tshaj 200 xyoo ntawm kev kho dua tshiab, cov ntaub ntawv sib txhuam tau dhau los ua qhov sib txawv thiab kev tawg?
1. Kev tiv thaiv ib puag ncig, qhov no yog qhov kev hloov pauv tseem ceeb heev, tshwj xeeb tshaj yog cov khoom sib txhuam ntawm asbestos. Kev nqus tau ntev ntev ntawm cov hmoov asbestos yooj yim ua rau asbestosis, thiab asbestos yuav tsis tshwm sim hauv cov ntaub ntawv sib txhuam tam sim no. Tau kawg, lwm yam khoom uas tsim kev puas tsuaj rau ib puag ncig thiab tib neeg lub cev yog hloov los ntawm lwm cov khoom siv hauv ib puag ncig.
2. Lub suab nrov, nrog rau kev hloov ntawm lub sijhawm, lub zog ntawm lub suab nrov tau nyiam ntau thiab ntau dua. Kev tsim cov suab nrov kuj tau txiav txim siab los ntawm cov khoom sib txhuam. Yog li ntawd, cov ntaub ntawv uas tsis tshua muaj suab nrov kuj yuav siv rau hauv cov khoom xyaw kom txo cov suab nrov los ntawm cov hauv paus hniav.
3. Kev kub siab ua haujlwm, qhov kub thiab txias kuj yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm cov phaj txhuam. Cov phaj kev sib txhuam tam sim no tau raug txhim kho, thiab qhov kub ntawm qhov sib txawv ntawm cov phaj sib txhuam tuaj yeem tiv taus tau zoo dua thiab zoo dua. Ntev npaum li nws nyob rau hauv ib txwm muaj, cov txheej txheem tam sim no tuaj yeem txaus siab.
4. Hnav tsis kam, vim yog cov khoom siv sib txhuam, kev hnav tsis kam ntawm cov phaj sib txhuam tsis siab, thiab nws yuav poob cov khoom, uas yog qhov tsis tsim nyog rau hnav tsis kam, thiab txawm tias tam sim no kev sib txhuam phaj yog cov qauv zoo tib yam, hnav. kuj tsis siab. Tsis yog qhov phem, thiab tam sim no muaj cov khoom siv ua haujlwm hnav-tiv taus uas ua tau raws li qhov xav tau ntawm cov neeg siv khoom. Qhov no zoo heev rau kev pab cuam lub neej ntawm kev sib txhuam hauv ob sab phlu.
