Cov lus qhia kev nyab xeeb
Thaum muaj xwm txheej ceev: tsis muaj xim tsis muaj roj nrog lub qab qab zib; Cov roj uas tsis yog nplaim taws; Oxidizing tus neeg sawv cev; Yuav ua rau los yog ua rau combustion ntau dua; Gas nyob rau hauv siab, yog rhuab tuaj yeem tawg; Lub sij hawm ntev los yog rov ua dua tuaj yeem ua rau lub cev puas tsuaj; Tej zaum yuav cuam tshuam fertility lossis fetus; Tej zaum yuav ua rau ua pa ua pa, ua rau qaug zog lossis kiv taub hau.
GHS Risk Pawg: Oxidizing gas 1, cov pa roj compressed - Compressed gas, toxicity kev yug me nyuam -1A, lub hom phiaj tshwj xeeb hauv nruab nrog cev toxicity -3, tshwj xeeb Target organ system toxicity rov raug -1.
Lus ceeb toom: Hazard Hazard nqe lus: tej zaum yuav ua rau los yog ua rau combustion ntau dua; Oxidizing tus neeg sawv cev; Gas nyob rau hauv siab, yog rhuab tuaj yeem tawg; Tej zaum yuav cuam tshuam fertility lossis fetus; Tej zaum yuav ua rau ua pa ua pa, ua rau qaug zog lossis kiv taub hau; Ntev ntev los yog rov ua dua tuaj yeem ua rau lub cev puas tsuaj.
Cov kev ceev faj:
· Kev tiv thaiv:
-- Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm.
-- Kev haus luam yeeb yog txwv tsis pub nyob hauv chaw ua haujlwm.
- Cia kom deb ntawm hluav taws thiab kub.
- Khaws kom deb ntawm cov khoom siv hluav taws xob thiab hluav taws kub.
Tiv thaiv kom tsis txhob muaj roj paug rau hauv qhov chaw ua haujlwm huab cua.
-- Tsis txhob tiv tauj nrog cov neeg ua haujlwm txo qis.
- Lub teeb loading thiab unloading thaum tuav los tiv thaiv kev puas tsuaj rau lub tog raj kheej thiab accessories.
- Tsis txhob tso tawm rau hauv ib puag ncig.
· Cov xwm txheej teb
--Yog nqus tau, 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 ua pa thiab lub plawv nres, pib CPR tam sim ntawd. Nrhiav kev kho mob.
- Sau cov xau.
Thaum muaj hluav taws kub, koj yuav tsum hnav lub tshuab ua pa, hnav ib lub cev tiv thaiv hluav taws, txiav tawm qhov cua, sawv ntsug rau saum cua, thiab tua fyog.
· Kev ruaj ntseg cia:
Khaws rau hauv qhov txias, qhov cua, tsis muaj hluav taws kub cia.
- Lub tsev khaws khoom kub yuav tsum tsis pub tshaj 30 ° C.
- Yuav tsum tau muab cais los ntawm cov khoom yooj yim (tuaj yeem) combustibles thiab txo cov neeg ua haujlwm, thiab yuav tsum tsis txhob sib xyaw.
-- Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev.
· Kev pov tseg pov tseg:
- Kev pov tseg raws li cov kev cai ntawm cov kev cai hauv lub tebchaws thiab hauv cheeb tsam. Los yog hu rau cov chaw tsim khoom los txiav txim siab txog cov txheej txheem pov tseg Lub cev thiab tshuaj lom neeg muaj kev phom sij: tsis yog-combustible tab sis combustion-txhawb, oxidizing, tshuaj loog, teeb meem rau ib puag ncig.
Kev phom sij rau kev noj qab haus huv:
Nws tau siv nyob rau hauv cov tshuaj rau ib ntev lub sij hawm raws li ib tug inhalation tshuaj loog, tab sis tam sim no nws yog siv tsawg. Kev nqus pa ntawm cov khoom sib xyaw thiab huab cua, thaum cov pa oxygen concentration tsawg heev, tuaj yeem ua rau tuag taus; Kev nqus tau ntawm 80% ntawm cov khoom sib xyaw ntawm cov khoom no thiab cov pa oxygen ua rau cov tshuaj loog sib sib zog nqus, thiab feem ntau tsis muaj kev cuam tshuam tom qab rov qab los.
Environmental hazards: Ua phem rau ib puag ncig.
