Nyob rau hauv xyoo tas los no, muaj ntau qhov xwm txheej ntawm ammonia xau thiab tawg hauv Suav teb. Ammonia xau hauv cov khw muag khoom txias, cov chaw tsim khoom noj hauv dej, cov khoom siv ammonia rhiav, cov nroj tsuag chiv, cov nroj tsuag tshuaj, thiab cov chaw ua liaj ua teb tau ua rau muaj kev puas tsuaj loj rau lub tebchaws thiab tib neeg lub neej thiab khoom. Qhov kev poob tau ua rau muaj kev txhawj xeeb thoob plaws hauv lub zej zog, thiab kev tiv thaiv ntawm ammonia leakage yuav tsum tau nyiam txhua tus neeg txoj kev saib xyuas zoo thiab nquag siv kev tiv thaiv.
Kev phom sij thiab kev tiv thaiv ntawm ammonia leakage xwm txheej:
Cov yam ntxwv ntawm ammonia
Ammonia yog ib qho ntawm cov tshuaj lom neeg uas muaj kev phom sij loj heev hauv kuv lub tebchaws. Ammonia tseem hu ua kua ammonia. Nws yog ib qho tshuaj lom thiab combustible gas. Ammonia muaj ntau yam kev siv. Nws yog siv los ua cov tub yees rau qhov txias txias, thiab lwm yam. Nws yog xim tsis muaj xim, muaj ntxhiab tsw ntxhiab, thiab muaj zog alkaline hauv cov kua hauv lub xeev. Nws tsim cov roj sib xyaw ua ke nrog huab cua, uas tuaj yeem ua rau combustion thiab tawg thaum raug qhib hluav taws lossis kub kub. Ammonia roj yog corrosive heev thiab muaj corrosive thiab irritating ntawm daim tawv nqaij cov ntaub so ntswg uas tuaj mus rau nws. Tom qab ammonia gas lom, lub caj pas thiab qhov ncauj hnov qhov khaus. Thaum cov pa ammonia nqus tau rau hauv tib neeg lub cev, nws yooj yim nkag mus rau hauv cov ntshav los ntawm alveoli, ua ke nrog hemoglobin, thiab rhuav tshem cov pa oxygen thauj mus los. Thaum lub concentration ntawm ammonia nyob rau hauv huab cua nce mus txog 500-700mg/m3, " xob laim" yuav tshwm sim. Kev nqus pa ntau dhau ntawm ammonia yuav ua rau muaj ammonia concentration hauv cov ntshav, uas yuav ua rau lub plawv nres thiab ua pa nres, uas ua rau muaj kev phom sij rau lub neej.
Ammonia Leak Escape Skills
Cov neeg tua hluav taws tau ceeb toom tias thaum muaj cov pa ammonia tso tawm, tub ceev xwm yuav tsum raug hu tam sim ntawd, thiab tib lub sijhawm, lawv yuav tsum ceev nrooj npog qhov ncauj thiab qhov ntswg nrog cov phuam ntub, thiab txav deb ntawm qhov chaw sai sai (feem ntau 50 meters deb ntawm lub upwind direction, thiab qhov deb ntawm downwind direction, zoo dua). Thaum koj pom ib tus neeg nyob ib puag ncig koj uas raug tshuaj lom los ntawm ammonia gas, coj lawv tawm ntawm qhov chaw thiab ua rau lawv nyob twj ywm thiab nqus pa oxygen; Yog tias koj ob lub qhov muag thiab tawv nqaij raug hlawv los ntawm ammonia roj, koj tuaj yeem ntxuav lawv kom huv si nrog dej huv lossis 2 feem pua ntawm cov tshuaj boric acid, siv tshuaj tua kab mob qhov muag, thiab xa mus rau tsev kho mob kom kho.
Ntxiv nrog rau kev paub txog kev khiav tawm yooj yim, kev saib xyuas thiab tiv thaiv qhov chaw muaj xwm txheej thiab txhim kho cov pa hluav taws xob / hluav taws xob hluav taws xob hluav taws xob tuaj yeem txo cov xwm txheej thiab kev puas tsuaj.
Lub teb chaws tus txheej txheem tau teev tseg tias nyob rau hauv cov chaw uas muaj hluav taws kub / muaj kuab lom, yuav tsum tau nruab ib lub tshuab hluav taws xob nyob rau hauv lub voj voog nrog ib lub vojvoog ntawm 7.5 meters txhawm rau txheeb xyuas cov pa tawm ntawm cov pa taws / cov pa phem. Thaum cov roj hluav taws xob / cov pa phem tawm, lub tshuab ntes roj yuav siv lub suab nrov thiab lub tswb nrov kom ceeb toom rau tib neeg kom ntsuas kev kub ntxhov los tiv thaiv kev sib tsoo.
Nws raug nquahu kom cov tuam txhab lag luam txhim kho cov cuab yeej ntsuas hluav taws xob hauv qhov chaw uas cov roj hluav taws xob / cov pa phem tau yooj yim kom xau, thiab teeb tsa lub suab thiab lub teeb ceeb toom nrog tus nqi buzzing siab, thiab nruab lub tswb tswj hauv cov chav saib xyuas yam tsis muaj teeb meem gases. Gas detectors tsim ib qho kev soj ntsuam roj. Thaum cov roj xau, lub kaw lus saib xyuas roj yuav ua siab ncaj tshaj tawm lub tswb ceeb toom rau tib neeg kom ntsuas kev kub ntxhov kom tsis txhob muaj kev pheej hmoo.
