Cov txheej txheem kev tswj hwm kev nyab xeeb yog ib qho cuab yeej tshuaj xyuas tsom rau kev tiv thaiv kev tso tawm ntawm cov khoom siv txhais tau tias yog "cov tshuaj lom neeg txaus ntshai" los ntawm EPA lossis OSHA.
Hais txog qhov no, PSM kev lag luam yog dab tsi?
Txheej Txheem Kev Tswj Xyuas Kev Nyab Xeeb ( PSM ) yog ib txoj cai uas tau tshaj tawm los ntawm US Department of Labor's Occupational Safety and Health Administration (OSHA). Kev lag luam tuav cov tshuaj phem yuav tsum tsim kom muaj txiaj ntsig zoo PSM qhov kev pab cuam uas tiv thaiv cov neeg ua haujlwm, cov neeg cog lus, thiab cov neeg tuaj xyuas ntawm qhov chaw.
Ib sab saum toj no, lub hom phiaj ntawm PSM yog dab tsi? Lub hom phiaj tseem ceeb ntawm kev tswj xyuas kev nyab xeeb ( PSM ) ntawm cov tshuaj lom neeg muaj kev phom sij heev yog los tiv thaiv kev tso tawm cov tshuaj lom neeg tsis zoo tshwj xeeb rau hauv qhov chaw uas tuaj yeem ua rau cov neeg ua haujlwm thiab lwm tus ua rau muaj kev phom sij loj.
Yog li ntawd, PSM cov txheej txheem them nyiaj yog dab tsi?
Cov PSM Standard txhais ib leeg txheej txheem raws li "txhua pawg ntawm cov hlab ntsha uas sib cuam tshuam thiab cais cov hlab ntsha uas nyob hauv qhov chaw uas muaj tshuaj lom neeg muaj peev xwm tuaj yeem koom nrog hauv kev tso tawm." Qhov kev txhais no tiv thaiv kev faib ua haujlwm rau hauv cov khoom me me uas tsis muaj ib qho twg muaj TQ.
Dab tsi yog 14 lub ntsiab ntawm PSM?
14 Yam Koj Yuav Tsum Tau suav nrog hauv Koj Txoj Haujlwm PSM

Dab tsi yog cov tswv yim thiab cov khoom tsim tawm hauv cov txheej txheem tsim khoom?
Hauv kev lag luam, yam tseem ceeb ntawm kev tsim khoom, peev txheej, lossis cov tswv yim yog qhov uas siv hauv cov txheej txheem tsim khoom los tsim cov khoom tawm - uas yog, cov khoom tiav thiab cov kev pabcuam. Tus nqi siv ntawm ntau yam inputs txiav txim seb qhov ntau npaum li cas ntawm cov zis raws li kev sib raug zoo hu ua ntau lawm muaj nuj nqi
Qhov kev pabcuam tsim khoom tsim khoom yog dab tsi?
Productivity yog qhov sib piv ntawm cov khoom tsim tawm thiab cov kev pabcuam thiab cov tswv yim ntawm cov peev txheej siv los tsim lawv. Qhov tseeb tias cov kev pabcuam kev lag luam tam sim no suav nrog ib nrab ntawm tag nrho cov kev lag luam tsim tawm tau coj peb mus rau qhov kev xav tias kev pabcuam-kev ua haujlwm yuav muab ib feem ntawm qhov kev piav qhia
Dab tsi yog qhov kev sib raug zoo ntawm tag nrho cov khoom tsim tau thiab cov khoom tsim tawm thawj zaug sau qhov sib npaug?
Koj tuaj yeem pom tias koj tus lej nyiaj hauv tuam txhab nyiaj tau txiav txim siab raws li hauv qab no: Koj qhov Net ntau lawm yog sib npaug rau koj qhov Kev Tsim Nyog Tag Nrho Tshem Tawm Tawm, uas yog tib yam li qhov sib npaug saum toj no uas hais txog Net Primary Production (NPP) = Gross Primary Production (GPP) Kev ua pa tawm (R)
Dab tsi yog tus tsim khoom tseem ceeb hauv cov khoom noj khoom haus?
Cov neeg tsim khoom tseem ceeb (cov kab mob uas ua rau lawv tus kheej noj los ntawm lub hnub ci thiab / lossis tshuaj lom neeg los ntawm cov seavents sib sib zog nqus) yog lub hauv paus ntawm txhua cov khoom noj - cov kab mob no hu ua autotrophs. Cov neeg siv khoom tseem ceeb yog cov tsiaj uas noj thawj cov neeg tsim khoom; lawv tseem hu ua herbivores (nroog noj)
Dab tsi yog kev lag luam kev lag luam hauv kev tsim khoom tshiab?
Kev tsim khoom tshiab pab cov tuam txhab sib txawv ntawm cov neeg siv khoom sib txawv thiab nthuav dav rau cov lag luam tshiab. Lub tswv yim kev lag luam khoom lag luam npaj koj lub lag luam los faib nyiaj thiab cov peev txheej, ntsuas kev pheej hmoo, thiab muab sijhawm tswj hwm koj cov khoom ua ntej nws mus txog ntu kev lag luam tshiab
