Folasaga

Dibromomethane. O loʻo taua i lalo se faʻamatalaga i meatotino, faʻaoga, metotia sauniuni ma faʻamatalaga saogalemu o le dibromomethane:

 

Tulaga lelei:

E i ai se manogi manogi i le vevela o le potu ma e le mafai ona solu i le vai, ae solu i le tele o solu masani masani.

O le Dibromomethyl ose vaila'au mautu e le fa'apala pe fa'afefeteina ni gaioiga fa'ama'i.

 

Fa'aaogā:

O le Dibromomethane e masani ona faʻaaogaina e avea o se solvent mo le faʻaogaina o meaola faʻasolosolo, faʻamavaeina poʻo le suʻeina o lipids, resins ma isi mea faʻalaʻau.

O le Dibromomethane o loʻo faʻaaogaina foi e avea o se mea mataʻutia mo le saunia o isi faʻalapotopotoga faʻapitoa, ma e iai faʻaoga i nisi o gaioiga faʻapisinisi.

 

Metotia:

O le Dibromomethane e masani lava ona saunia e ala i le taliina o le methane ma le bromine.

I lalo o tulaga tali, e mafai e le bromine ona sui se tasi pe sili atu hydrogen atoms i le methane e fausia ai le dibromomethane.

 

Fa'amatalaga Saogalemu:

O le Dibromomethane e oona ma e mafai ona mitiia e ala ile inhalation, pa'u pa'u, po'o le inuina. E ono iai ni a'afiaga fa'alesoifua maloloina mo se taimi umi.

E tatau ona ofuina ni mea e puipuia ai le tagata lava ia e pei o totigilima, mata tioata, ma talipupuni mata pe a fa'aaoga.

E tatau ona faʻaeteete ina ia aloese mai le faʻafesoʻotaʻi ma mea e faʻamumu ai pe a tagofia ma teu le dibromomethane, aua e mu.

E tatau ona teuina le Dibromomethane mai le vevela ma le maualuga o le vevela i se nofoaga malulu ma lelei.

Pe a faʻaaogaina, teuina poʻo le faʻaaogaina o le dibromomethane, e tatau ona matua mulimulitaʻia faiga faʻaoga saogalemu ina ia mautinoa le saogalemu o le tagata lava ia. I tulaga o fa'alavelave, e tatau ona faia ni fa'alavelave fa'afuase'i talafeagai.
