Ko te Xylene (CAS 1330-20-7) he whakarewa matū hinu me te rauemi matū matua, e toru ngā isomers (o-, m-, me te p-xylene) e hanga ana i tētahi wai pumau, kore tae me te kakara kakara motuhake. E whakanuia ana mō tōna kaha ki te utu me te hototahi ki ngā rauemi, he rauemi taketake maha-whakamahinga e tutuki ana i ngā whakaritenga hanga me te hanga ahumahi pakari.
He whānuitia te whakamahinga puta noa i ngā rāngai o te ao, ko te mahi matua he whakarewa mahi-teitei mō ngā paninga, ngā waituhi tā, me te horoi i ngā wāhanga hiko; he rauemi matua hoki mō te hanga waikawa p-phthalic (he matū matua mō ngā kirihou PET) me ngā matū pai. Ka tautokohia anō hoki e ēnei matū whakaputa ngā ahumahi tae atu ki te takai, te hanga paninga motuka, te hanga taputapu hiko, te tukatuka kakahu, me te whakapaipai whare.
He maha ngā kōwhiringa taumata o tā mātou hua xylene (tohu ahumahi me te tohu parakore teitei) kia rite ki ngā hiahia whakaputa kanorau, me te whakahaere kounga tino pakari kia iti ai te paru me te pumau/pūmautanga o te moni. Ka oati mātou ki te tuku pono i te nuinga, ngā tuhinga mō ngā taonga morearea katoa (tae atu ki te MSDS me te tiwhikete UN), me ngā otinga whakahaere kua whakaritea mō te kawe wai mura. Hei tāpiri, ka whakaratohia e tā mātou tīma hangarau ngaio he tautoko whaiaro—pēnei i te aratohu āhua rokiroki me ngā taunakitanga hototahi whakarewa—kia pai ake ai te whai huatanga o tō whakaputa me te haumaru mahi.

Te Tākai o te Xylene
I roto i te pūtu kirihou kupenga 180kg, i te pūtu IBC rānei.
Rokiroki: Rokirokihia ki roto i tētahi whare putunga hauhautanga, maroke, ā, he hauhautanga hoki; Kia tino wehea mai i ngā matū whakahāweawe (hei tauira, te waikawa hauota, ngā peroxide), ngā waikawa kaha, me ngā halogen. Kaua rawa e whakaranua, e rongoatia rānei.
