To taub covcov haujlwm tseem ceeb thiab cov xwm txheej uas cov nplaim hluav taws ua haujlwm yuav tsum hnav khaub ncawsyog qhov tseem ceeb rau kev ua raws li kev nyab xeeb hauv chaw ua haujlwm, kev tswj hwm kev lag luam PPE, thiab kev tiv thaiv kev raug mob ua haujlwm. Cov khaub ncaws ua haujlwm nplaim taws tsis yog cov khaub ncaws ua haujlwm thoob ntiaj teb; lawv yog cov cuab yeej tiv thaiv tshwj xeeb tsim los tiv thaiv hluav taws, thaiv cov nplaim taws, thiab zam kev kub hnyiab los ntawm cov khaub ncaws ignition. Raws li OSHA, NFPA thiab EN cov qauv kev nyab xeeb kev lag luam, tshwj xeeb siab - txoj haujlwm txaus ntshai thiab chaw ua haujlwm raug cai tswj hwm kev hnav khaub ncaws uas muaj ntawv pov thawj hluav taws kub hnyiab los tshem tawm cov phom sij uas muaj hluav taws kub.
1. Petrochemical, Roj thiab roj ua haujlwm txoj haujlwm (Yuav tsum tau Theem: Siab tshaj)
Petroleum thiab chemical industries yog cov xwm txheej zoo tshaj plaws uas cov khaub ncaws ua haujlwm tsis zoo yuav tsum hnav. Kev ua haujlwm ib puag ncig muaj cov pa roj, cov tshuaj ua kua tsis haum, thiab cov khoom siv siab -, uas yooj yim ua rau hluav taws tawg. Ntawm - cov neeg ua haujlwm hauv chaw, cov neeg ua haujlwm ua cov roj av, cov neeg ua haujlwm kho cov pa roj, thiab cov neeg ua haujlwm tshuaj lom neeg lub chaw ua haujlwm yuav tsum hnav NFPA 2112 lossis EN 11612 cov khaub ncaws ua haujlwm tau lees paub. Cov khaub ncaws zoo tib yam paj rwb lossis tshuaj fiber ntau yog txwv tsis pub, vim cov ntaub hluavtaws yaj thiab poob rau hauv qhov kub siab, ua rau mob hnyav heev.
2. Fais fab tuag, substation thiab siab -Voltage Operation Scenarios
Kev ua haujlwm hluav taws xob muaj nyob rau siab - hluav taws kub thiab arc flash ib puag ncig. High- cov khoom siv hluav taws xob tsis ua haujlwm tau yooj yim ua rau hluav taws xob arcs thiab siab kub sai sai - kub. Cov neeg ua haujlwm saib xyuas cov chaw tsim hluav taws xob, cov neeg ua haujlwm substation, cov neeg ua haujlwm tsim hluav taws xob thiab cov neeg ua haujlwm vuam hluav taws xob tau suav nrog hauv cov npe tseem ceeb uas cov khaub ncaws ua haujlwm tsis zoo yuav tsum hnav. Cov nplaim hluav taws kub hnyiab thiab arc-cov khaub ncaws ua haujlwm tiv taus tuaj yeem cais cov arc flash siab kub, tiv thaiv cov khaub ncaws tawg, thiab txo cov kev pheej hmoo raug mob thaum muaj xwm txheej tsis ua haujlwm.
3. Metallurgy, Steelmaking thiab High -Tub kub rauv Posts
Steel mills, smelting nroj tsuag thiab forging rhiav tuav ntev -lub sij hawm ultra- kub ua hauj lwm tej yam kev mob. Splashing molten steel, siab -kub slag thiab radiant tshav kub yuav ignite workwear zoo tib yam txhua lub sij hawm. Cov neeg ua haujlwm hauv lub tshuab hluav taws xob, cov neeg ua haujlwm casting thiab cov neeg ua haujlwm kuaj xyuas cov cua sov yuav tsum hnav cov khaub ncaws ua haujlwm ruaj khov uas muaj qhov kub thiab txias. Cov khaub ncaws tshwj xeeb no zam cov nplaim hluav taws kub hnyiab thiab tawg, muab kev tiv thaiv kev ruaj ntseg txuas ntxiv thaum lub sij hawm ntev - hloov siab - kub ua haujlwm.
4. Vuam, txiav thiab thermal ua hauj lwm scenarios
Hluav taws xob vuam, roj txiav, laser txiav thiab hlau thermal ua ua tas li Mars, siab - kub sparks thiab splash khib nyiab. Cov khoom tawg tawg tawg no yooj yim hlawv los ntawm cov khaub ncaws ua haujlwm zoo tib yam. Welders, txiav cov neeg ua haujlwm thiab cov neeg ua haujlwm kev cob qhia yog cov haujlwm uas yuav tsum tau hnav cov khaub ncaws ua haujlwm tsis zoo. Cov ntaub ntawv pov thawj nplaim hluav taws tuaj yeem tiv taus qhov cuam tshuam, tiv thaiv kev kub nyhiab hauv zos, thiab zam qhov loj - thaj tsam khaub ncaws ignition tshwm sim hauv qhov chaw ua haujlwm hnyav.
5. Cov foob pob hluav taws, foob pob hluav taws thiab chaw cia khoom phom sij
Cov chaw ua haujlwm uas muaj cov ntaub ntawv tawg, cov hmoov hluav taws kub thiab cov khoom siv tshuaj lom neeg muaj peev xwm ua tau zoo heev - hluav taws kub thiab tawg rhiab heev. Txawm tias me me los ntawm hluav taws xob zoo li qub lossis siab - qhov kub thiab txias tuaj yeem ua rau muaj kev nyab xeeb. Cov thawj coj ntawm lub tsev khaws khoom, cov neeg tuav cov khoom tsim kev puas tsuaj thiab cov neeg ua haujlwm tshawb nrhiav yuav tsum hnav cov khaub ncaws tiv thaiv zoo li qub thiab cov nplaim hluav taws kub hnyiab kom tshem tawm cov khoom siv hluav taws xob thiab hluav taws xob zoo li qub.
6. Cov Qauv Ua Raws Cai & Kev Nyab Xeeb Tus Nqi
Txhua qhov xwm txheej tseem ceeb uas yuav tsum tau ua kom muaj nplaim taws ua haujlwm yuav tsum ua raws li OSHA 29 CFR cov cai tswj kev nyab xeeb, NFPA 2112 cov qauv tiv thaiv hluav taws kub thiab EN ISO 14116 nplaim taws kis cov qauv. Kev hnav khaub ncaws ua haujlwm tsis zoo tsuas yog kev tswj hwm kev nyab xeeb ntawm kev lag luam nkaus xwb tab sis kuj yog lub luag haujlwm raug cai rau cov neeg ua haujlwm siab -. Nws txo qis kev raug mob kub hnyiab, zam kev nplua rau kev nyab xeeb ntawm kev lag luam, thiab txhim kho tag nrho ntawm - thaj chaw muaj peev xwm tswj hwm kev pheej hmoo.

Clarifying tuscov haujlwm tseem ceeb thiab cov xwm txheej uas cov nplaim hluav taws ua haujlwm yuav tsum hnav khaub ncawspab cov tuam txhab ua kom tiav kev faib PPE thiab kev tswj hwm kev nyab xeeb. Petrochemical, hluav taws xob fais fab, metallurgy, vuam thiab cov khoom siv phom sij lag luam yuav tsum tau ua kom nrov nrov cov khoom siv hluav taws xob hluav taws xob los tsim kom muaj kev ruaj ntseg ntawm kev tiv thaiv hluav taws kub thiab hluav taws kub.
