Ntchito zopulumutsa m'malo oletsedwa

Matanki osungira, ma culverts apansi, ma silos otsekedwa ndi malo ena oletsedwa amatha kukhala ndi mpweya wokwanira, mpweya wa poizoni ndi woopsa umadziunjikira, ndipo malo amkati mwa malowa ndi ovuta, choncho n'zosatheka kumaliza kuwunika kwachilengedwe pasadakhale. Pogwira ntchito yopulumutsa m'malo oletsedwa, kugwiritsa ntchitomafakitale SCBA machitidweakhoza kulola ogwira ntchito yopulumutsa kuti aziyenda momasuka, pomwe sakukhudzidwa ndi chilengedwe choopsa cha mpweya mumlengalenga.

Mitundu yosiyanasiyana ya zochitika zadzidzidzi

Chemical ogwira ntchito poizoni kutayikira mpweya, kuphulika zida kuphulika, woopsa mankhwala zoyendera galimoto kutayikira ndi zina zadzidzidzi, chilengedwe chilengedwe ndi zosayembekezereka, ndende zoipitsa, okhutira mpweya akhoza kusintha nthawi iliyonse. Ogwira ntchito zadzidzidzi akafika pamalowa, ayenera kuvala SCBA nthawi yoyamba kuti agwire ntchito yotaya, kuteteza chitetezo chawo, komanso nthawi yomweyo, kumaliza bwino ntchito yadzidzidzi.

Kodi Muyenera Kugwiritsa Ntchito Liti SAR?

Kupereka mpweya mosalekeza komanso mawonekedwe opepuka komanso osavuta kugwiritsa ntchito a SCBA amapangitsa kuti ikhale zida zodzitchinjiriza zomwe zimagwiritsidwa ntchito nthawi zonse m'mafakitale, makamaka oyenera nthawi yayitali, yoyendetsedwa ndi malo osasunthika, okhala ndi magawo atatu otsatirawa a zochitika zenizeni:

Kugwira ntchito kwamakampani kwanthawi yayitali

Mchenga kuphulika ndi kuchotsa dzimbiri, kupopera mbewu mankhwalawa, ntchito mosalekeza mu msonkhano mankhwala, etc., kutalika kwa ntchito limodzi nthawi zambiri maola angapo, ndi kutalika kwa mpweya SCBA a kotunga sangathe kukwaniritsa kufunika, pamene yaitali chubu chopumira dongosolo akhoza kuzindikira mosalekeza mpweya, ndi ndi opepuka kuvala mamangidwe, akhoza kwambiri kuchepetsa kulemedwa kwa woyendetsa thupi, ndi kumapangitsanso bwino ntchito.

Malo oyendetsedwa m'malo ogwirira ntchito

Mapiritsi aatali a chubu ndi oyenera kugwiritsidwa ntchito m'madera omwe kuyang'anira zachilengedwe kungathe kumalizidwa ndi zipangizo zamakono musanayambe kugwira ntchito, kumene mtundu ndi ndende ya zonyansa zimamveka bwino, komanso kumene kuchuluka kwa zowonongeka kumakhalabe kokhazikika ndipo sikumasintha mwadzidzidzi panthawi ya opaleshoni. Mu chilengedwe chamtunduwu, palibe chifukwa chodalira mpweya wodziyimira pawokha wa SCBA, ndipo chopumira chautali cha chubu chingathe kutsimikizira chitetezo pamene kuchepetsa mtengo wa ntchito ndi kukonza zipangizo.

Malo Ogwira Ntchito Okhazikika kapena Ochepa

M'malo ochepa ogwirira ntchito monga malo ogwirira ntchito m'ma workshops, madoko osungiramo akasinja osungiramo, malo osungiramo zitsulo zokhazikika, ndi zina zotero, ntchito zosiyanasiyana za ogwira ntchito zimakhala zosasunthika, ndipo payipi yoperekera mpweya imatha kuphimba malo onse ogwira ntchito, kotero kuti sipadzakhala zopinga za mapaipi zomwe zimakhudza ntchito. Kugwiritsiridwa ntchito kwa chubu chopumira chachitali mumtundu woterewu sikungokwaniritsa zofunikira zachitetezo, komanso ntchito yabwino.

Momwe Mungasankhire Dongosolo Loyenera Lopumira

Pachimake posankha SCBA kapena yaitali chubu respirator ndi kuphatikiza pa malo malo, zosowa ntchito ndi chigamulo chokwanira, kupewa ngozi zoopsa chifukwa cha kusankha molakwika, komanso kukulitsa mphamvu ya ntchito ya zipangizo, kufunikira kwapadera kuganizira mfundo zisanu zikuluzikulu, pamene akutsatira mfundo zomveka bwino za kusankha.

Mfundo Zofunika Kuziganizira

1. Mulingo wowopsa ndi mpweya wabwino: ngati ndi malo owopsa a IDLH, malo osadziwika oipitsa, amaika patsogolo SCBA, ngati ali ndi chiopsezo chochepa, chokhazikika choipitsidwa ndi chilengedwe cholamulidwa, mukhoza kusankha chopumira chautali cha chubu.
2. Kuzungulira kwa oxygen:SCBAiyenera kugwiritsidwa ntchito m'malo opanda mpweya wa okosijeni pomwe mpweya wa okosijeni uli wochepera 19.5%, komanso m'malo omwe mpweya wa okosijeni ndi wabwinobwino, SCBA imatha kusankhidwa malinga ndi zina.
3. Kutalika kwa ntchito: Ngati nthawi ya opaleshoni imodzi ikupitirira mphindi 60, chopumira chautali cha chubu chimakondedwa. Kwa opareshoni kwakanthawi kochepa (30-60 mphindi), SCBA ndiyoyenera. 4.
4. Zofunikira za oyendetsa: ngati mukufuna kuyenda momasuka ndipo malo ogwirira ntchito ndi ovuta, sankhani SCBA; ngati malo ogwirira ntchito akhazikika ndipo mayendedwe ake ndi ochepa, sankhani chopumira chachitali cha chubu.
5. Kuganizira Kuthawa Mwadzidzidzi: Ngati pali ngozi yadzidzidzi pamalo ogwira ntchito ndipo kuthawa mwadzidzidzi kumafuna kuyenda mofulumira, sankhani SCBA; ngati malo ogwirira ntchito ali okhazikika ndipo njira yopulumukira ikuwonekera, sankhani chopumira chachitali cha chubu.

Malangizo Osankha

Ngati malo ogwirira ntchito sakudziwika kuti ali pachiwopsezo kapena pachiwopsezo chachikulu, sankhani SCBA mwachindunji. Ngati ndi nthawi yayitali yogwira ntchito m'mafakitale pansi pa malo okhazikika komanso osinthika, sankhani SAR kuti ikwaniritse zomwe mukufuna. Panthawi imodzimodziyo, ziribe kanthu mtundu wa zipangizo zomwe mungasankhe, muyenera kuonetsetsa kuti zipangizozo zikugwirizana ndi miyezo ya chitetezo cha dziko, komanso kuti kuyezetsa ndi kukonza nthawi zonse kumatsirizidwa kuti zitsimikizire kuti zidazo zili bwino.

SCBA ndi SAR monga mitundu iwiri yayikulu ya zida zotetezera kupuma zomwe zimaperekedwa ndi mpweya, ngakhale mfundo yachitetezo ndi yosiyana, yogwiritsidwa ntchito pazochitika zosiyanasiyana, koma ndi kupanga mafakitale, kupulumutsa mwadzidzidzi kuteteza chitetezo cha kupuma kwa ogwira ntchito pazida zazikulu, chimodzi ndichofunika kwambiri.

Kwa mabizinesi ndi ogwira ntchito, kuweruza kolondola kwa malo ogwirira ntchito, nthawi ndi zosowa zam'manja, sankhani zida zoyenera zotetezera kupuma, ndikuteteza chitetezo, kutsatira malamulo, kukonza bwino makiyi. Posankha, mutha kuphatikiza zosankha zomwe zili m'nkhaniyi, molingana ndi zochitika zenizeni ndi, pangani chitetezo cholimba.
