Cov lus qhia kev nyab xeeb
Emergency Overview: Flammable gas. Thaum sib xyaw nrog huab cua, nws tuaj yeem tsim qhov sib xyaw tawg, uas tawg thaum raug tshav kub lossis hluav taws qhib. Gases hnyav dua huab cua thiab sib sau ua ke hauv qhov chaw qis. Nws muaj qee yam tshuaj lom neeg.
GHS Risk Pawg:
Flammable gas Class 1, tawv nqaij corrosion/Irritation Class 2, mob qhov muag raug mob/qhov muag Irritation Class 2A, cov hom phiaj tshwj xeeb hauv nruab nrog cev toxicity Class 3, tej hom phiaj hauv nruab nrog cev toxicity Class 2
Lus ceeb toom: Danger
Cov lus piav qhia txog kev phom sij: cov pa taws heev; Gas nyob rau hauv siab, yog rhuab tuaj yeem tawg; Ua rau tawv nqaij khaus; Ua rau qhov muag khaus heev; Ntev ntev los yog rov ua dua tuaj yeem ua rau lub cev puas tsuaj.
Cov kev ceev faj:
· Kev tiv thaiv:
- Khaws kom deb ntawm qhov hluav taws kub, qhov hluav taws kub, qhov chaw kub. Tsis haus luam yeeb. Tsuas yog siv cov cuab yeej uas tsis tsim cov nplaim taws. Siv cov khoom tawg-pov thawj, qhov cua thiab teeb pom kev zoo. Thaum lub sij hawm hloov cov txheej txheem, lub thawv yuav tsum tau muab tso rau hauv av thiab txuas nrog kom tsis txhob muaj hluav taws xob zoo li qub. Khaws lub thawv airtight.
- Siv cov cuab yeej tiv thaiv tus kheej raws li xav tau.
- Tiv thaiv kom tsis txhob muaj roj paug rau hauv qhov chaw ua haujlwm huab cua. Tsis txhob nqus pa.
Tsis txhob noj, haus lossis haus luam yeeb hauv chaw ua haujlwm.
Tsis txhob tso rau hauv ib puag ncig.
· Cov xwm txheej teb
- Thaum muaj hluav taws kub, siv dej pos huab, ua npuas ncauj, carbon dioxide, hmoov qhuav los tua hluav taws. Yog tias nqus tau, tshem tawm ntawm qhov chaw muaj kab mob kom tsis txhob raug mob ntxiv. Pleev, yog tias qhov chaw ua pa yog qhov ntiav lossis ua pa tau nres kom paub tseeb tias txoj hlab pa ntshiab, muab cov pa ua pa. Yog tias ua tau, kev nqus pa oxygen kho mob yog tswj hwm los ntawm cov neeg ua haujlwm cob qhia. Mus rau tom tsev kho mob lossis tau txais kev pab los ntawm kws kho mob.
Kev ruaj ntseg cia:
Khaws lub thawv kaw. Khaws rau hauv ib qho chaw txias, ventilated warehouse. Khaws kom deb ntawm hluav taws thiab cua sov.
· Kev pov tseg pov tseg:
Kev pov tseg raws li txoj cai hauv tebchaws thiab hauv cheeb tsam, lossis tiv tauj nrog cov chaw tsim khoom los txiav txim siab txog txoj kev pov tseg. Kev phom sij rau lub cev thiab tshuaj lom neeg: Flammable. Thaum sib xyaw nrog huab cua, nws tuaj yeem tsim qhov sib xyaw tawg, uas tawg thaum raug tshav kub lossis hluav taws qhib. Gas accumulates nyob rau hauv qis dua cov huab cua. Nws muaj qee yam tshuaj lom neeg lub cev.
Kev phom sij rau kev noj qab haus huv:
Silicane tuaj yeem ua rau lub qhov muag khaus, thiab silicane tawg los tsim cov silica. Kev sib cuag nrog cov khoom siv silica tuaj yeem ua rau lub qhov muag khaus. Kev nqus tau siab ntawm silicane tuaj yeem ua rau mob taub hau, kiv taub hau, lethargy, thiab ua pa sab sauv. Silicane tuaj yeem ua rau khaus khaus thiab ua pa. Kev raug mob siab rau silicane tuaj yeem ua rau mob ntsws thiab pulmonary edema. Silicone tuaj yeem ua rau tawv nqaij.
Environmental hazards:
Vim yog spontaneous combustion nyob rau hauv cov huab cua, silane burns ua ntej nkag mus rau hauv av. Vim tias nws hlawv thiab tawg hauv huab cua, silane tsis nyob hauv ib puag ncig ntev. Silane tsis khaws cia hauv cov khoom muaj sia.
