Ukuqapha Nokulawula Umjikelezo
Inhloso yokuqapha nokulawula ukuvalwa kwe-EO (Ethylene Oxide) ukukhombisa ukuthi inqubo eqinisekisiwe neshiwo yokuvala inzalo isetshenzisiwe emkhiqizweni. Idatha evela kumjikelezo ngamunye wokuvala inzalo kufanele irekhodwe futhi igcinwe ukuze kuqinisekiswe ukuthi ukucaciswa kwenqubo yokuvala inzalo okuqinisekisiwe kuhlangatsheziwe. Lokhu kufanele kufake okungenani okuqukethwe okulandelayo:
a) Ubufakazi bokuthi izinga lokushisa lemvelo lomkhiqizo lifinyelele izinga lokushisa elincane eliqinisekisiwe lapho ungena ekwelapheni (uma kusetshenziswa). Lokhu kungafezwa ngokuvumela umthwalo ukuthi ujwayelane nemvelo isikhathi esincane esibekiwe. Uma izinga lokushisa lesitoreji laziwa, asikho isidingo sokunquma izinga lokushisa lomkhiqizo ngaphambi kokungena endaweni yokwelashwa. Uma umkhiqizo uke wachayeka emazingeni okushisa aphezulu, njengalapho uthuthwa, umkhiqizo ungase udinge ukugcinwa isikhashana ngaphambi kokwelashwa kusengaphambili ukuze uzinze izinga lokushisa lawo langaphakathi kanye nomswakama endaweni eyamukelekayo.
b) Ukuqapha nokurekhoda izinga lokushisa kanye nomswakama endaweni yokwelapha ngaphambi kwesikhathi (uma kusetshenziswa) ezindaweni ezithile.
c) Isikhathi sokuqala sokwelashwa kwangaphambili komthwalo ngamunye wokuvala inzalo kanye nesikhathi lapho umthwalo ususwa endaweni yokwelapha ngaphambi kwesikhathi (uma kusetshenziswa).
d) Isikhathi esiphakathi kokukhipha umthwalo wokuvala inzalo endaweni yokwelapha ngaphambi kwesikhathi (uma kusetshenziswa) kanye nokuqala komjikelezo wokuvala inzalo.
e) Izinkomba zokusebenza kahle kwesistimu yokujikeleza kwegesi ekamelweni ngesikhathi sesigaba sokuchayeka kwegesi (uma sisetshenziswa).
f) Izinga lokushisa nokucindezela ngaphakathi kwegumbi kuwo wonke umjikelezo wokuvala inzalo.
g) Umswakama ongaphakathi kwegumbi phakathi nesigaba sokucubungula, njengoba kukalwa ngokucindezela noma ngokuqondile.
h) Ukuqinisekisa ukuthi i-Gaseous EO yethuliwe egunjini lokuvala inzalo.
i) Ukucindezela kwenyuka ngaphakathi kwegumbi lokuvala inzalo kanye nenani noma ukugxila kwe-EO esetshenzisiwe.
j) Isikhathi sokucubungula.
k) Isikhathi sokuchayeka.
l) Isikhathi, izinga lokushisa, noshintsho lwengcindezi (uma lukhona) phakathi nesigaba sokungenisa umoya kanye/noma nemisebenzi yokukhipha umoya (uma kusetshenziswa).
Ukukhishwa kwe-EO Sterilization
a) Indlela Yenkomba Yebhayoloji
Uma izinkomba zebhayoloji (i-EPCD eqinisekisiwe) zisetshenziswa, kufanele zisatshalaliswe kuwo wonke umthwalo wokuvala inzalo, okuhlanganisa nezindawo okunzima kakhulu ukuvala amagciwane noma izindawo ezaziwa ukuthi zihlobene nalezi zindawo ezinzima. Uma kusetshenziswa ukwelashwa kusengaphambili, izinkomba zebhayoloji kufanele zibekwe ngaphambi kokwelashwa kwangaphambili.
Izinkomba zebhayoloji kufanele zisuswe emthwalweni wokuvala inzalo ngemva kokuphela komjikelezo wokuvala inzalo futhi zikhuliswe ngokushesha ngangokunokwenzeka ukuze kuvunyelwe izinkomba zebhayoloji ukuthi zivuseleleke. Uma zingakhuliswanga ngesikhathi esifanele, imiphumela yokuchayeka ku-EO esele ngesikhathi sokuvuselelwa okubambezelekile kufanele ihlolwe.
Ukukhula kwezinkomba zebhayoloji kufanele kuhlaziywe ukuze kutholwe ukuthi ukukhula akubangelwa yini ukwehluleka ukuhlangabezana nezicaciso zenqubo ebonakalayo, okungadinga ukuphinda inqubo yokuqinisekisa.
b) Indlela Yokukhipha Ipharamitha
Ukukhishwa kwepharamitha kuncike ekuqinisekiseni ukuthi wonke amapharamitha enqubo engokwenyama ahlangabezana nezicaciso zokukhululwa ngaphandle kokusetshenziswa kwezinkomba zebhayoloji. Isekelwe kuphela ezilinganisweni namarekhodi amapharamitha ezinqubo zomzimba futhi isebenza njengesimemezelo esanele sokwanela kwenqubo yokuvala inzalo.
Ukukhishwa kwepharamitha kuvunyelwe kuphela lapho zonke izinhlaka zenqubo zicacisiwe, zilawulwa, futhi ziqashwe ngokuqondile. Ngakho-ke, lapho kusetshenziswa ukukhululwa kwepharamitha, kufanele kube khona okokusebenza kokulinganisa okuqondile kwezinga lokushisa kanye nomswakama ngaphakathi kwegumbi kanye nokuhlaziywa okuqondile kokugxiliswa kwe-EO, ukuqoqa nokurekhoda amapharamitha wenqubo yokuvala inzalo nokuqinisekisa ukuthi inqubo yokuvala inzalo ihambisana nezicaciso.
Ngokungeziwe ekufakazeleni ukuthi amapharamitha wenqubo yokuvala inzalo ahlangabezana nezicaciso zokuvala inzalo, ukukhululwa kwepharamitha kuphinde kudinga ukulinganisa nokurekhoda idatha eyengeziwe elandelayo:
Ukulinganisa izinga lokushisa ngaphakathi kwegumbi okungenani kusuka ezindaweni ezimbili kuwo wonke umjikelezo wokuvala inzalo.
Ukulinganisa ngokuqondile umswakama ngaphakathi kwegumbi phakathi nesigaba sokucubungula.
Ukunquma ukugxila kwe-EO ngokuhlaziywa okuqondile kwegesi yegumbi lokuvala inzalo ngezikhathi ezithile, ukuze kuqinisekiswe ngokugcwele ukuthi izimo ezidingekayo ziyahlangatshezwana naso sonke isikhathi sokuchayeka.
