Ua Ntej Kev Ua Haujlwm
Inhalation: yog nqus tau, txav tus neeg mob mus rau cua tshiab.
Cov tawv nqaij tiv thaiv: Tshem cov khaub ncaws tsis huv thiab cov tawv nqaij yaug nrog xab npum thiab dej. Yog tias koj tsis xis nyob, nrhiav kev kho mob.
Kev Tiv Thaiv Qhov Muag: Cais cov tawv muag thiab yaug nrog dej ntws lossis dej qab ntsev. Nrhiav kev kho mob sai.
Kev noj haus dej: Wellgle, tsis txhob ua ntuav ntuav. Nrhiav kev kho mob sai.
Kev Tiv Thaiv Hluav Taws Kub
Extinguishing tus neeg sawv cev:
Tua hluav taws nrog dej mood, qhuav hmoov, ua npuas dej lossis carbon dioxide extinguishing tus neeg sawv cev. Zam txhob siv dej ua kom ncaj qha rau kev tua hluav taws, uas yuav ua rau cais cov kua thiab kis hluav taws.
Cov phom sij tshwj xeeb:
Tsis muaj ntaub ntawv
Kev ceev ceev thiab tiv thaiv kev tiv thaiv:
Cov neeg tua hluav taws yuav tsum hnav cov pa ua pa, hnav cov khaub ncaws hnav hluav taws, thiab tua hluav taws.
Yog tias ua tau, txav lub thawv los ntawm hluav taws mus rau qhov chaw qhib.
Ntim hauv thaj chaw hluav taws yuav tsum tau khiav tawm haujlwm tam sim ntawd yog tias lawv raug rho tawm lossis tawm suab los ntawm cov khoom siv phom sij.
Cais tawm ntawm qhov chaw sib tsoo thiab txwv tsis pub cov neeg ua haujlwm tsis cuam tshuam los ntawm kev nkag mus.
Muaj thiab kho cov dej hluav taws kom tsis txhob muaj kuab paug ib puag ncig.
Khaws lub thawv ntim, cia rau hauv qhov chaw txias, cia yuav tsum tsis pub dhau 37 ° C, yuav tsum tau sib cais los ntawm oxidants tshuaj, tsis txhob muab cov zaub mov cia.
50kg 200kg 200kg / chim / chim lossis ntim raws li cov neeg siv khoom.
It yog cov organic intermediate uas tuaj yeem tau los ntawm eserification ntawm 4-bromobutyrate thiab tert-butanol. Nws tau tshaj tawm tias 4-tert-butyl bromobutyryray tuaj yeem siv los npaj cov khoom siv dag ntxias ntawm Eomylurea.
