• Hluav taws kub thiab tawg phom sij: Tsis-flammable.

Nqe 4: Kev Pab Ua Ntej

• Tiv tauj daim tawv nqaij: Tshem tawm cov khaub ncaws uas tsis huv tam sim ntawd thiab ntxuav cov tawv nqaij nrog dej txaus kom ntev li 15 feeb. Nrhiav kev kho mob.
• Kev Tiv Thaiv Qhov Muag: Tam sim ntawd rub daim tawv muag thiab yaug qhov muag nrog dej txaus los yog ntsev kom tsawg li 15 feeb. Nrhiav kev kho mob.
• Inhalation: Ceev nrooj tawm ntawm qhov chaw mus rau huab cua ntshiab. Khaws txoj hlab cua kom meej. Yog ua pa nyuaj, muab cov pa oxygen. Yog tias ua tsis taus pa, ua pa ua pa. Nrhiav kev kho mob.
• Kev Noj Qab Haus Huv: Yaug qhov ncauj nrog dej. Nrhiav kev kho mob.

Nqe 5: Kev Tiv Thaiv Hluav Taws Xob

• Flammability: Tsis yooj yim flammable.
• Extinguishing Media: Siv cov tshuaj qhuav qhuav, carbon dioxide, dej pos, los yog ua npuas ncauj.
• Kev tua hluav taws: Hauv qhov tsim nyog, cov neeg tua hluav taws yuav tsum hnav lub tshuab ua pa ntawm tus kheej. Cov dej phwj tuaj yeem siv los ua kom txias kaw cov thawv.

Nqe Lus 6: Kev Cai Tso Cai Tsis Txaus Siab

• Cov kauj ruam los ua thaum cov khoom xau los yog nchuav:
• Tshem tawm ntawm thaj chaw, tsis txhob nqus cov pa, plua plav, lossis kev sib cuag nrog kua. Yog tias muaj kev nyab xeeb, txiav tawm qhov xau. Rov qab cov khoom nchuav thiab ntxuav cov khoom seem. Txau dej los ntxuav qhov chaw nchuav. Tiv thaiv cov khoom spilled los ntawm cov dej ntws, kwj dej, thiab dej hauv lub cev.
• Txoj kev pov tseg pov tseg: pov tseg pov tseg raws li cov cai hauv zos thiab cov cai.

Tshooj 7: Kev tuav thiab khaws cia

• Hmoov yog ntim rau hauv hnab woven lined nrog yas, nrog ib tug luj ntawm 25-30 kg ib lub hnab.
• Tus neeg sawv cev no yooj yim soluble hauv dej, yog li zam lub hnab tawg thaum thauj thiab khaws cia; khaws nws nruj me ntsis noo-pov thawj. Yog hais tias clumped vim ya raws, crushed thiab dhau los ntawm ib tug 0.63mm sieve ua ntej siv.
• Tus neeg sawv cev no yuav tsis deteriorate nrog kev khaws cia ntev.

Nqe 8: Kev Tiv Thaiv Kab Mob thiab Tiv Thaiv Tus Kheej

• Rau kev lag luam mus sij hawm ntev, ua raws li cov txheej txheem no:
• Kev tiv thaiv ua pa: Siv cov cuab yeej ua pa uas tsim nyog rau tus kheej lossis lub qhov ncauj qhov ntswg yog tias tsim nyog.
• Kev ua pa: Ua kom muaj cua zoo hauv chaw ua haujlwm, ua tau raws li OSHA kev nyab xeeb thiab kev noj qab haus huv cov cai tam sim no.
• Kev Tiv Thaiv Tus Kheej: Tshuaj tiv thaiv tsom iav, roj hmab lossis PVC hnab looj tes. Yog tias tsim nyog, hnav khaub ncaws tsis zoo lossis khau boots, thiab muab cov chaw ntxuav qhov muag thiab da dej nyab xeeb.
• Kev Pom Zoo Ua Haujlwm Kev Nyab Xeeb: Hnav cov khoom tiv thaiv tus kheej. Tshem tawm thiab ntxuav cov khaub ncaws tsis huv ua ntej rov siv dua.

Nqe 9: Lub cev thiab tshuaj lom neeg

• Yooj yim soluble hauv dej, insoluble hauv cawv, tsis muaj ntxhiab tsw ntxhiab.
