Izinto ezikhona ngokuphambili ezikhuliswa ngemisebenzi yezinhlobo ezininzi zikwetha ngonyaka ezininzi zibe isicatshulwa. Lezo zinto zihamba ngokukhawuleza, yeyiphi, zinceda ukuba zikhawuleze nezinto ezimbini. Ngokuhlukileyo lokho ukuba zikhawuleza ngokukhawuleza kufanelelela lezo zinto ukusebenzisa ukwenza izinto ezi- polyether polyols zintsha, futhi phakathi kwi-spray foam insulation, nokulayiswa kwi-coatings kusasazisiwe.
Ngoku enye yemithombo yokubhubheka kwezokhayanate ngu-ku bonakele ukuba bazixhumana nokugcwalisa izindlela zesikhenkiso kanye nokulungu lamaqhawe ababhubheka nabo.
Ngoba polyol isocyanate baza kuhlanganiswa nokuphucula amandla ngokwesixa lokugcina, futhi azivamiswe ngamagaba amacala njengesiOSHA, noma iOccupational Safety and Health Administration. SiOSHA, ngokushesha, ihlola ukuba izindawo zokusetyenziswa zizihlinzekile kulelwandle. Kunezinye izinhlobo zezimvo zamasetha aziphumeleyo ezinikezela izokhayanate zidlule ukufunda ukuba abantu babo babuyele kuqhubeka.
Ngokugqibela ukuba i-isocyanates zingabizwa ngamandla, lezinye izinto zezakhono zinikezela kwiqhakamselelo lokusebenza. Kwesiqephu esisindileyo kusasazisiwe, kwi-coatings nokanye noma ku-adhesives, bayenza imigca yezintsha ezininzi zezinto.
Kwesiqendu, polyol kunye no-isocyanate zingaba-chemistries ezikhoyo okunye kunye nokuba zikhulu kuhlanganiswa kuhlanganiselo lwezinto ezaziqashelwe kulesi sikhathi, futhi phakathi kwesilayisini nokulayiswa. Kodwa bazingene ukubulala umthombo wemoya okanye umkhuhlane omphandle kwegcino elilinganayo.
