Kev tiv thaiv
Kev tiv thaiv ua pa: Hnav lub npog ntsej muag lub ntsej muag roj rau tus kheej (tag nrho npog) thaum muaj peev xwm tiv nrog nws cov vapor. Thaum muaj xwm txheej ceev lossis khiav tawm, koj yuav tsum hnav lub tshuab ua pa.
Kev tiv thaiv qhov muag: Kev tiv thaiv kab mob ua pa tau tiv thaiv.
Kev tiv thaiv lub cev: Hnav daim kab xev tiv thaiv kab mob.
Kev tiv thaiv tes: Hnav hnab looj tes roj hmab.
Lwm tus: Kev haus luam yeeb, noj mov thiab haus cawv yog txwv tsis pub nyob ntawm qhov chaw. Hloov koj cov khaub ncaws ua haujlwm tam sim. Tsis txhob haus cawv ua ntej thiab tom qab ua haujlwm. Da dej hauv dej sov. Ua tib zoo txheeb xyuas cov tshuaj lom. Ua haujlwm ua ntej thiab kuaj mob tsis tu ncua.
Kev ntsuas thawj zaug
Kev sib cuag ntawm daim tawv nqaij: Tshem tawm cov khaub ncaws tsis huv tam sim ntawd thiab yaug daim tawv nqaij kom huv si nrog dej soapy thiab dej huv. Nrhiav kev kho mob.
Kev sib cuag qhov muag: Nqa daim tawv muag thiab yaug nrog dej los yog ntsev. Nrhiav kev kho mob.
Inhalation: Tshem tawm sai sai ntawm qhov chaw mus rau huab cua ntshiab. Khaws koj txoj hlab cua kom meej. Muab cov pa oxygen yog ua pa nyuaj. Yog tias ua tsis taus pa, muab kev ua pa tawm tam sim ntawd. Nrhiav kev kho mob.
Noj: Haus dej sov txaus kom ntuav thiab nrhiav kev kho mob.
