Cov lus qhia kev nyab xeeb
Thaum muaj xwm txheej ceev: tsis muaj xim tsis muaj roj nrog tsw tsw tsw; Toxic, tuaj yeem ua rau lossis ua rau muaj kev kub ntxhov; Oxidizing tus neeg sawv cev; 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; Ua phem los ntawm kev nqus pa.
GHS Risk Pawg: Oxidizing gas -1, cov pa roj compressed - compressed gas, tshwj xeeb lub hom phiaj hauv nruab nrog cev toxicity los ntawm kev sib cuag -2, mob toxicity - inhalation -4.
Lus ceeb toom: Danger
Cov lus hais txog kev puas tsuaj: tuaj yeem ua rau lossis ua rau muaj kev kub ntxhov ntau dua; Oxidizing tus neeg sawv cev; 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; Ua phem los ntawm kev nqus pa.
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.
- nruj nreem kaw kom muaj cov pa txaus hauv zos thiab ua pa dav dav.
-- Nws raug pom zoo tias cov neeg ua haujlwm hnav cov khoom tiv thaiv tus kheej.
- Tiv thaiv kom tsis txhob muaj roj paug rau hauv qhov chaw ua haujlwm huab cua.
-- Cia kom deb ntawm hluav taws thiab kub.
-- Kev haus luam yeeb yog txwv tsis pub nyob hauv chaw ua haujlwm.
-- Khaws kom deb ntawm cov khoom siv hluav taws xob thiab hluav taws xob.
-- 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. Yog ua pa nyuaj, ntawm no
Muab cov pa oxygen. Yog ua pa thiab lub plawv nres, pib CPR tam sim ntawd. Nrhiav kev kho mob.
-- Sau cov xau.
Thaum muaj hluav taws kub, txiav tawm qhov chaw huab cua, cov neeg tua hluav taws hnav lub qhov ncauj qhov ntswg, thiab sawv ntsug ntawm qhov chaw nyab xeeb kom tua hluav taws.
· Kev ruaj ntseg cia:
- Khaws rau hauv qhov chaw txias, qhov cua uas muaj kuab lom warehouse.
- Qhov kub ntawm lub tsev yuav tsum tsis pub tshaj 30 ℃.
- Yuav tsum tau muab cais los ntawm cov khoom yooj yim (flammable), txo cov neeg ua haujlwm, cov tshuaj siv tau, thiab lwm yam, 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 cai ntawm cov kev cai hauv tebchaws thiab hauv zos thiab cov cai. Los yog hu rau cov chaw tsim khoom los txiav txim siab qhov chaw pov tseg
Dharma.
Kev phom sij ntawm lub cev thiab tshuaj lom neeg: tshuaj lom, oxidizing, tuaj yeem ua rau lossis ua rau muaj kev sib kis ntau dua, ua rau muaj kev phom sij rau ib puag ncig. Kev cuam tshuam, kev sib txhuam, thaum qhib hluav taws lossis lwm qhov hluav taws kub yog qhov tawg heev. Nws yog ib qho yooj yim rau ignite thaum nyob rau hauv kev sib cuag nrog combustibles.
Kev phom sij rau kev noj qab haus huv:Nws yog irritating rau txoj hlab pa. Nws tuaj yeem cuam tshuam rau lub siab thiab lub raum. Rov ua dua lossis ua pa ntev ntev tuaj yeem ua rau muaj fluorosis.
Environmental hazards:Ua phem rau ib puag ncig.
