Kev ntsuas thawj zaug
Inhalation: Yog tias nqus tau, txav tus neeg mob mus rau huab cua ntshiab.
Kev sib cuag ntawm daim tawv nqaij: Tshem tawm cov khaub ncaws tsis huv thiab yaug daim tawv nqaij kom huv si nrog xab npum thiab dej. Yog tias koj tsis xis nyob, nrhiav kev kho mob.
Kev sib cuag qhov muag: cais daim tawv muag thiab yaug nrog dej ntws los yog dej ntsev. Nrhiav kev kho mob tam sim ntawd.
Noj : Gargle, tsis txhob ntuav ntuav. Nrhiav kev kho mob tam sim ntawd.
Kev tiv thaiv hluav taws
Extinguishing agent:
Tshem tawm hluav taws nrog dej pos huab, hmoov qhuav, ua npuas ncauj lossis carbon dioxide extinguishing tus neeg sawv cev.
Tsis txhob siv cov dej ntws ncaj qha los tua hluav taws, uas yuav ua rau cov kua hluav taws kub hnyiab thiab kis tau hluav taws.
Kev phom sij tshwj xeeb: Tsis muaj ntaub ntawv.
Kev tiv thaiv hluav taws thiab kev tiv thaiv:
Cov neeg tua hluav taws yuav tsum hnav lub tshuab ua pa, hnav khaub ncaws tua hluav taws, thiab tua hluav taws upwind.
Yog tias ua tau, txav lub thawv ntawm qhov hluav taws kub mus rau qhov chaw qhib.
Cov thawv ntim hauv thaj chaw tua hluav taws yuav tsum tau khiav tawm tam sim yog tias lawv tsis muaj xim lossis tawm suab los ntawm cov cuab yeej kev nyab xeeb.
Cais qhov chaw sib tsoo thiab txwv tsis pub cov neeg ua haujlwm nkag mus. Ntim thiab kho cov dej tua hluav taws kom tsis txhob muaj kuab paug ib puag ncig.
Khaws rau hauv qhov chaw txias & qhuav.
Ntim hauv 25kg / nruas, lossis ntim raws li cov neeg siv khoom xav tau.
