1.Xa ukhetha iikomityi zephepha ezilahlwayo, musa ukujonga nje umbala wekomityi yephepha.Musa ukucinga ukuba umbala omhlophe, ngakumbi ucoceko.Ukuze wenze indebe ibonakale imhlophe, abanye abavelisi beekomityi zephepha bongeza inani elikhulu le-agent emhlophe ye-fluorescent.Nje ukuba ezi zinto ziyingozi zingene emzimbeni womntu, ziya kuba zi-carcinogens ezinokubakho.Iingcali zicebisa ukuba xa ukhetha indebe yephepha, abemi kufuneka bathathe ifoto phantsi kwesibane.Ukuba indebe yephepha ibonakala eluhlaza okwesibhakabhaka phantsi kokukhanya kwe-fluorescent, kuthetha ukuba i-agent ye-fluorescent idlula umgangatho, kwaye abathengi kufuneka bayisebenzise ngokuqaphela.

2.Umzimba wekomityi uthambile kwaye awunamandla, ngoko lumka ukuvuza kwamanzi.Ukongeza, khetha iikomityi zephepha ezinodonga olungqingqwa kwaye oluqinileyo.Iikomityi zephepha ezinobunzima bomzimba obunzima zithambile kakhulu xa zipinkiwe.Emva kokugalela amanzi okanye iziselo, ziya kuphazamiseka kakhulu xa zithathwa, okanye zingakwazi ukucholwa, okuya kuchaphazela ukusetyenziswa.Iingcali zithi iikomityi zephepha ezikumgangatho ophezulu ziyakwazi ukugcina amanzi iiyure ezingama-72 zingavuzi, ngelixa iikomityi zephepha ezikumgangatho ophantsi ziya kuvuza kwisiqingatha seyure.

3.Umbala wodonga lwekomityi uyathandeka, ngoko qaphela ityhefu ye-inki.Iingcali zolawulo lomgangatho zibonise ukuba iikomityi zephepha zipakishwa kunye.Ukuba zifumile okanye zingcolisekile, ukungunda kuyakwenzeka ngokuqinisekileyo, ngoko ke iikomityi zephepha ezifumileyo mazingasetyenziswa.Ukongeza, ezinye iikomityi zephepha ziya kuprintwa ngeepatheni ezinemibala kunye namagama.Xa iikomityi zephepha zihlanganiswe ndawonye, ​​i-inki engaphandle kwendebe yephepha iya kuchaphazela ngokuqinisekileyo umaleko wangaphakathi wekomityi yephepha ejikelezileyo.I-inki ine-benzene kunye ne-toluene, eyingozi empilweni.Thenga iikomityi zephepha ezingena-inki okanye eziprinta ngaphantsi ngaphandle.

4.Abenzi bekomityi yephepha bahlula phakathi kweekomityi ezibandayo kunye neekomityi ezishushu, kwaye "ngamnye unomsebenzi wakhe."Ekugqibeleni iingcaphephe zabonisa ukuba iikomityi zephepha ezilahlwayo esiqhele ukuzisebenzisa zinokwahlulwa zibe ziindidi ezimbini: iikomityi zesiselo esibandayo neekomityi zesiselo esishushu.
