Ingabe ukubumba umjovo wemikhiqizo yepulasitiki kunobuthi futhi kuphephile?

Ipulasitikiukubumba umjovoyona ngokwayo ayiyona inqubo enobuthi noma eyingozi, kodwa phakathi nenqubo yokukhiqiza, amanye amakhemikhali nezimo zokusebenza zingase zihileleke ukuthi, uma zingalawulwa futhi zingalawulwa kahle, zibe nemiphumela emibi empilweni yabasebenzi kanye nemvelo.

Ihlanganisa ikakhulukazi izici ezintathu ezilandelayo:

(1) Izinto zokusetshenziswa ezisetshenziswa ekubumbeni umjovo wepulasitiki ngokuvamile ziyizinhlayiya zenhlaka yepulasitiki, engase iqukethe izinto eziyingozi, njenge-phthalates (njenge-dibutyl phthalate noma i-dioctyl phthalate), ezibhekwa njengengozi empilweni yomuntu.Ngaphezu kwalokho, ezinye izinto zokusetshenziswa kwepulasitiki zingabola ngesikhathi sokucubungula ukukhiqiza izinto eziyingozi, njenge-vinyl chloride, i-styrene, njll.

(2) Izithasiselo nezinsiza ezisetshenziswa enqubweni yokubumba umjovo wemikhiqizo yepulasitiki, njengamaplasitiki, ama-stabilizer, izinto zokuthambisa, njll., zingase zibe nomthelela empilweni yomuntu.Lezi zinto zivame ukuba nomthelela omncane emzimbeni womuntu ekugxilweni okuphansi, kodwa zingaba yingozi empilweni yomuntu uma zihogelwe, zimunywa noma zivezwe esikhunjeni ngobuningi.

(3) Inqubo yokubumba umjovo yemikhiqizo yepulasitiki izoveza umsindo nokudlidliza, uma abasebenzi bechayeka kulezi zici isikhathi eside, kungase kuholele ekulahlekelweni kokuzwa nokukhathala ngokomzimba.

Ukuze uqinisekise ukuphepha kwenqubo yokubumba umjovo wemikhiqizo yepulasitiki, kufanele kuthathwe uchungechunge lwezinyathelo, ikakhulukazi ezihlanganisa izici ezintathu ezilandelayo:

(1) Amabhizinisi kufanele aqinise ukuphathwa kwezempilo emsebenzini futhi anikeze ukuqeqeshwa okudingekayo kwezempilo emsebenzini kanye nezinto zokuzivikela, njengamagilavu, imaski, ama-earplug, njll.

(2) Ukuhlolwa okungenayo nokwamukelwa kwezinto ezingavuthiwe kufanele kuqiniswe ukuze kuqinisekiswe ukuthi izinto ezingavuthiwe ezisetshenziswayo ziyahlangabezana namazinga afanele kazwelonke nawendawo.

(3) Amabhizinisi kufanele ahlele ngokunengqondo inqubo yokukhiqiza nesakhiwo semishini, anciphise umsindo nokudlidliza ohlelweni lokukhiqiza, futhi agweme ukuchayeka ngokweqile kwabasebenzi.

Ngamafuphi, ipulasitikiukubumba umjovoinqubo ngokwayo akuyona inqubo enobuthi futhi eyingozi, kodwa kuyadingeka ukunaka ukuvikelwa kwempilo yomuntu siqu, ukuhlolwa kwempahla eluhlaza, ukuhlelwa kwemishini kanye nokulawula umsindo ohlelweni lokusebenza ukuvikela impilo yabasebenzi kanye nokuphepha kwemvelo.
