Tej yam tseem ceeb ntawm cov hluav taws: dab tsi mus nrhiav nyob rau hauv thawj qhov chaw?

Hluav taws kub yog ib tug indescribable kev puas tsuaj nyob rau hauv nws tus kheej - raug kev txom nyem vaj tse puas lawm tangible cuab tam (vaj tse, nyiaj, cov khoom), sau los ntawm cov tsev neeg rau decades. Tsis ceev faj hluav taws kub yog raug mob rau kev kho mob thiab lub neej ntawm muaj zeej nyob qhov. Tab sis nyob rau tib lub sij hawm, muaj cov qhov hluav taws kub muaj tej yam yog tsis yog li ntawd sawv daws rau cov neeg tsis tshua muaj colliding los yog tsis colliding nrog tej catastrophic teeb meem.

Kom meej meej, cov thawj ntawm cov yam tseem ceeb yog qhov hluav taws kub thiab cov concomitant kub. Hais tias lawv ua loj puas tsuaj rau vaj tse, tib neeg noj qab haus huv thiab cov cuab yeej. Tab sis tom qab lawv yog cov lwm yam hluav taws kub muaj mob muaj nkees, thiab ua ntej ntawm - cov tsis muaj oxygen. Txawm cov tub ntxhais kawm los ntawm cov chav kawm ntawm Science News for KIDS, physics paub tias combustion yog tau tsuas yog nyob rau hauv lub xub ntiag ntawm no gas. Thiab nrog rau kev qhib hluav taws, tshwj xeeb tshaj yog yog hais tias nws cheeb tsam loj, oxygen yog noj nrog zoo kawg ceev. Vim hais tias ntawm yog dab tsi nws tsis muaj pib, ua rau cov pa starvation. Thaum thawj zaug rau theem, nws yuav txais ceev lub plawv dhia, tsis lub hlwb kev ua si thiab impaired kom sib haum. Thaum heev tsawg ntawm cov pa, txoj kev tuag tshwm sim yuav luag instantaneously.

tshuaj yam

Hluav taws kub muaj mob muaj nkees kuj haus luam yeeb, pa roj carbon dioxide thiab cov pa roj carbon monoxide roj cua. CO ₂ (carbon dioxide) tsis tsw thiab tsis muaj xim, tab sis yog hais tias tus cua nws yog ntau tshaj 10%, cov neeg poob nco qab, thiab kom tau tawm ntawm lub tsev nyob rau hauv cov nplaim taws tsis tau. Carbon monoxide muaj ib tug insidious thiab yus - txawm ib tug me me concentration ntawm nws rau ib nrab ib teev yuav tua ib tug neeg zoo dua tshaj tshuaj rog nrog. Haus luam yeeb nkag mus rau hauv lub tu siab daim ntawv teev hu ua "hluav taws tsis muaj" vim hais tias cov heev yooj yim orientation nyob rau hauv ib tug nchauv ib puag ncig. Cov neeg siv ntau lub sij hawm kom tau tawm ntawm txoj kev, thiab yog li ntawd ntau npaum li cas yuav tau txais kev kub tuag los yog tshuaj lom los ntawm combustion khoom uas tau teev tseg.

lub cev yam

Hluav Taws tsis muaj - qhov no kev puas tsuaj (cev qhuav dej ntawm cov vaj tse los yog ib txhia muaj designs). Thiab ntawm no yog ib tug uas muaj feem yuav tsis tau tsuas yog mus ua txhaum, piv txwv li, qhob phab ntsa, tab sis kuj lawv tawg tsam, uas tej zaum yuav ya rau ntawm ib tug heev loj deb.

Secondary hluav taws tsis muaj

Nyob rau hauv tas li ntawd mus rau lub yav tas los hais thooj, nws yog ib nqi nco ntsoov kua uas siab kub yuav tsuag. Ntxiv mus, lawv kub yuav ua tau saum toj no lub kub taw tes ntawm cov dej. Ces tej zaum kis thiab spilling lom thiab txawm tej ntaub ntawv los ntawm lub puas khoom. Tsis muaj tsawg txaus ntshai thiab nraus nyob ntawm tej, tshwj xeeb yog high voltage (electric shock, hluav taws kub, muaj coob tus neeg yuav tuag). Thiab, ntawm chav kawm, no koj yuav muaj xws li ntshai thiab poob siab, vim hais tias leej twg tau txais mus rau hauv ib tug tua hluav taws cuab yog ntiab tawm los ntawm lub sab sauv plag tsev ntawm skyscrapers yog feem ntau rau ib pliag kom txog rau thaum lub rescuers.

teeb meem twv ua ntej

Thaum xwv hluav taws yuav coj zoo kev pab rau kwv yees hluav taws tau teeb meem. Yog li ntawd, yog hais tias muaj yog ib co tshuaj tsob nroj, nws yog ib zajlus kom xav hais tias cov huab cua muaj ib tug lossis loj npaum li ntawm tshuaj lom tshuaj tebchaw. Paub txog dab tsi ua lub Hoobkas, koj yuav Tshuag nyob rau hauv ua ntej cov tshuaj kom txo tau tshuaj lom los. Yog hais tias zes chaw nres tsheb los yog chaw muag roj tsheb, ntawm chav kawm, hais tias ua ntej ntawm tag nrho cov koj yuav tsum muab tso tawm ib yam dab tsi uas yuav tawg.
