Nplaim taws tiv thaiv kev nyab xeeb ua haujlwm khaub ncaws (fr ua haujlwm khaub ncaws) yog cov khoom siv tiv thaiv tseem ceeb tsim los rau cov neeg ua haujlwm ua haujlwm nyob rau hauv ib puag ncig kub, nplaim taws, arc lossis molten hlau txaws. Cov khaub ncaws nplaim hluav taws yuav tsum tau los yog pom zoo rau cov haujlwm hauv qab no thiab cov xwm txheej ua haujlwm:
�� 1, Muaj kev pheej hmoo hluav taws kub thiab tawg ib puag ncig
Petroleum, natural gas thiab chemical kev lag luam
Drilling platform neeg ua hauj lwm, refinery tswv, pipeline tu neeg ua hauj lwm thiab tshuaj processors
Cov ntsiab lus txaus ntshai: hluav taws kub nyhiab thiab tshuaj lom neeg tawg los ntawm cov roj crude/natural gas to ��
Kev tua hluav taws thiab kev cawm thaum muaj xwm txheej ceev
Cov neeg tua hluav taws (cov khaub ncaws tua hluav taws nws tus kheej yog cov khoom siv hluav taws xob hluav taws xob), pab pawg neeg tua hluav taws kub ntxhov
Cov ntsiab lus txaus ntshai: kev sib cuag ncaj qha nrog hluav taws qhib, siab - pa taws kub, thiab rov ua kom cov hluav taws kub hnyiab
⚡ 2, Kev lag luam muaj kev pheej hmoo siab arc
Lub zog ua haujlwm
High voltage electricians, substation tu neeg ua hauj lwm, kis kab mob tu neeg ua hauj lwm
Risk point: qhov kub thiab txias ntawm arc flash tuaj yeem ncav cuag 19000℃C ☢️
�� 3, Kub kub hlau ua haujlwm
Kev lag luam metallurgy thiab foundry
Steelmaker, furnace operator, hlau caster, welder
Cov ntsiab lus txaus ntshai: molten hlau txaws (xws li molten hlau thiab txhuas), kub kub hluav taws xob hluav taws xob
Vuam thiab txiav ua haujlwm
Electric welder thiab plasma cutter
Cov ntsiab lus txaus ntshai: khaub ncaws ignited los ntawm sparks thiab scalded los ntawm cov tee dej
✈️ 4, Tshwj xeeb siab - thaj chaw muaj kev pheej hmoo
Aviation thiab kev sib tw
Cov tub rog tsav dav hlau (hluav taws- tiv thaiv lub dav hlau), cov neeg tsav tsheb sib tw, pab pawg cawm
Cov ntsiab lus txaus ntshai: roj to hluav taws kub, siab - hluav taws kub sib tsoo ceev
Hav zoov tiv thaiv hluav taws
Hav zoov tua hluav taws tua hluav taws thiab cov neeg soj ntsuam hluav taws
Risk point: ceev kis thiab deflagration ntawm hav zoov hluav taws (flashover)
�� ️ 5, Lwm yam scenes xav tau kev tiv thaiv
Tub rog thiab kev ua haujlwm tshwj xeeb
Armored tsheb crew, nkoj cav chav tub rog, explosive ordnance pov tseg cov neeg ua haujlwm
Laboratories thiab tshwj xeeb kev lag luam
Flammable chemicals researcher, iav txiag (kub kub rauv)
✅ Cov txheej txheem tseem ceeb rau kev xaiv cov khaub ncaws tsis zoo
Daim ntawv pov thawj xav tau:
Kev lag luam: ua raws li NFPA 2112 (anti flash fire) lossis NFPA 70E (anti arc)
Kev lag luam fais fab: ASTM f1506 arc tiv thaiv tus qauv
Kev tiv thaiv hluav taws: NFPA 1971 cov khaub ncaws tiv thaiv hluav taws
Cov khoom siv: aramid (Nomex ®), nplaim taws retardant paj rwb, carbon fiber sib xyaw, thiab lwm yam, yuav tsum tua tus kheej (automatically extinguished thaum tawm hauv qhov hluav taws kub)
Dab tsi ⚠️ ceeb toom tseem ceeb: cov khaub ncaws nplaim hluav taws tsis yog "cov khaub ncaws tiv thaiv hluav taws", tab sis sib ntaus sib tua rau lub sijhawm khiav tawm rau cov neeg ua haujlwm los ntawm kev ncua kev sib txuas. Nws yuav tsum tau koom tes nrog cov nplaim retardant headgear, hnab looj tes thiab daim npog qhov ncauj los tsim ib tug tiav kev tiv thaiv system.
Thaum koom nrog cov hauj lwm saum toj no, nco ntsoov xyuas kom meej tias cov khaub ncaws ua hauj lwm ua raws li kev lag luam kev nyab xeeb specifications, thiab tsis tu ncua ua kev tiv thaiv kev ua tau zoo los xyuas kom meej tias lub neej yuav cawm tau thaum lub sij hawm tseem ceeb!
