Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav, xyuas kom muaj qhov cua txaus, thiab zam cov plua plav tsim thaum 4-Bromo-4'-chlorobiphenyl raug tso tawm, hnav cov cuab yeej tiv thaiv tus kheej nrog rau cov hnab looj tes tsis muaj tshuaj lom neeg, tsom iav kev nyab xeeb, thiab kev tiv thaiv ua pa yog tias tsim nyog.
2. Sau 4-bromo-4'-chlorobiphenyl CAS 23055-77-8 los ntawm kev cheb los yog nqus cov plua plav, siv cov cuab yeej pov thawj thiab cov khoom tawg, thiab muab tso rau hauv cov thawv kaw tsim nyog rau kev pov tseg.
3. Tsis txhob tsim cov plua plav huab cua thaum lub sij hawm ntxuav kom tsis txhob ua pa tawm, tshem tawm tag nrho cov khoom siv hluav taws xob, thiab tiv thaiv cov khoom los ntawm kev nkag mus rau cov dej ntws los yog cov dej hauv chav dej vim nws cov dej muaj kuab lom.
4. Tshem tawm cov khoom siv pov tseg raws li hauv zos, xeev, thiab tsoomfwv cov cai tswjfwm ib puag ncig, nyiam dua los ntawm kev tso cai tshuaj lom neeg puas tsuaj lossis tswj kev tua hluav taws nrog flue roj txhuam, tsis txhob tso tawm rau hauv cov kav dej.
Kev tiv thaiv hluav taws
1. 4-Bromo-4'-chlorobiphenyl tsis raug cais raws li cov nplaim hluav taws kub heev tab sis tuaj yeem decompose nyob rau hauv hluav taws kub, nrog lub teeb nyem ntawm kwv yees li 110 degree, emitting pa phem thaum koom nrog hluav taws.
2. Siv cov hmoov qhuav 4-bromo-4'-chlorobiphenyl CAS 23055-77-8 chemical hmoov, carbon dioxide, los yog dej cawv-resistant ua npuas ncauj los tua hluav taws uas muaj cov khoom.
3. Cov neeg tua hluav taws yuav tsum hnav nws tus kheej- muaj cov cuab yeej ua pa thiab cov iav tiv thaiv tag nrho thaum tuav cov hlawv 4-Bromo-4'-chlorobiphenyl vim muaj cov pa phem xws li carbon monoxide, carbon dioxide, nitrogen oxides (NOx), hydrogen chloride, thiab hydrogen bromide .
4. Thaum lub sij hawm combustion, tej zaum yuav emit irritant thiab toxic fumes; tiv thaiv hluav taws los ntawm kev nkag mus rau hauv cov dej los yog cov dej hauv chav dej, thiab sau cov dej tua hluav taws sib cais kom tsis txhob muaj kev sib kis ntawm ib puag ncig.
