Igcinwe kwindawo yokugcina impahla eyomileyo nenomoya.
I-1. Isikhongozeli: IVenkile ye-TMG kwikhonteyina etywiniweyo yokuthintela ungcoliseko kunye nokuphuma. Sebenzisa izikhongozeli ezenziwe ngezinto ezihambelana neziseko ezomeleleyo.
2. Iqondo lobushushu Iqondo lokushisa legumbi lilungile, kodwa kufuneka ligcinwe ngaphantsi kwe-25 ° C (77 ° F) nanini na.
3. Umswakazi: Kuba i-TMG yi-tygroscopic (ifumana umswakama emoyeni), kubalulekile ukuyigcina kwimo ephantsi yokufuma.
4. Amanyathelo okhuseleko: Qinisekisa ukuba indawo yokugcina ingena umoya kwaye uthatha amanyathelo afanelekileyo okhuseleko njengoko i-TMG inokucaphuka kulusu namehlo.
I-5. Ileyibhile: Iziqholo zelebheli ngokucacileyo kwigama leekhemikhali, uxinzelelo kunye naluphi na ulwazi olunobungozi.
I-Tetramethylguidine (TMG) inokuba yingozi kumzimba womntu ukuba amanyathelo okhuseleko afanelekileyo angathatyathwa. Nazi ezinye iindawo eziphambili malunga netyhefu kunye nokhuseleko:
1. Ukucaphuka: I-TMG ingacaphukisa ulusu, amehlo, kunye nephecana lokuphefumla. Ukudibana ngqo kunye nolwelo kunokubangela ukutshisa iikhemikhali okanye ukucaphukisa.
2. Ukuphefumla: Ukuphefumla kwe-TMG Vapor kunokubangela ukucaphukisa ukuphefumla kunye neminye imiphumo emibi.
3. Ukungenisa: Ukungenisa kwe-TMG kunokuba yingozi kwaye kunokubangela ukucaphukisa i-gestrointenal okanye ezinye iziphumo.
4. Amanyathelo okhuseleko: Xa uphatha i-TMG, hlala usebenzisa izixhobo ezifanelekileyo zokhuselo (PPE) njengeigloves, i-goggles, kunye nengubo yelebhu. Sebenza kwindawo enomoya ongena kakuhle okanye usebenzise i-hood yesitshixo ukunciphisa ukubonakaliswa.
5. Uncedo lokuQala: Ukuba licacisiwe kwiziyobisi, thatha amanyathelo afanelekileyo oncedo, njengokugungxula indawo echaphazelekayo ngamanzi kwaye ufuna unyango ukuba kunyanzelekile.
Xa uhambisa iTitramethylguanine (TMG), kufuneka kuthathwe amanyathelo okhuseleko ukuqinisekisa ukhuseleko kunye nokuthotyelwa kwemigaqo. Nazi ezinye zeengqwalaselo eziphambili zokuthatha ingqalelo:
1. Ukuthotyelwa kolawulo: Jonga kwaye ulandele imigaqo yendawo, yesizwe, kunye nezamazwe aphesheya malunga nokuhamba kweempahla eziyingozi. I-TMG inokuhlelwa njengezixhobo ezinobungozi, ke qinisekisa ukuba onke amaxwebhu okuhambisa achanekile kwaye agqibezele.
2. Ukupakisha: Sebenzisa izixhobo zokupakisha ezifanelekileyo ezihambelana ne-TMG. Iziqulatho kufuneka zibe zenziwe nge-leakproof kwaye zenziwe ngezinto ezinokumelana neempawu zomchiza. Sebenzisa amatywina asesibini ukukhusela ukuvuza ngexesha lokuhamba.
I-3. Ileyibhile: Bile ilebheli ifake ifakibhu ngegama leekhemikhali, isimboli enobungozi, kunye naluphi na ulwazi olufanelekileyo lokhuseleko. Oku kubandakanya ukuphonononga imiyalelo kunye nolwazi loqhakamshelwano olungxamisekileyo.
4. Ulawulo lobushushu: Qinisekisa ukuba iimeko zokuhambisa zigcina amaqondo obushushu azinzileyo, njengoko amaqondo obushushu agqithisileyo anokuchaphazela uzinzo lwe-TMG.
5. Kulumkele ukunyakama: Kuba i-TMG yi hygroscopic, nceda uqinisekise ukuba ukupakishwa bubungqina bokufuma.
I-6. Indlela yoThutho: Khetha indlela efanelekileyo yothutho (umhlaba, umoya, ulwandle) ezihambelana nemigaqo yeempahla eziyingozi. Qinisekisa ukuba imoto yothutho ixhotywe ngezixhobo eziyimfuneko zokukhusela izinto ezinokubakho ngokukhuselekileyo.
7. Iinkqubo zongxamiseko: Nika ulwazi kwiinkqubo ezingxamisekileyo kwimeko yokuchitheka okanye ukuvuza ngexesha lothutho. Qinisekisa ukuba abasebenzi ababandakanyekayo kwezothutho baqeqeshelwa ukuphatha izixhobo eziyingozi.
8. Amaxwebhu: Oku kubandakanya onke amaxwebhu afanelekileyo okuhambisa anjengeBhili, iphepha leDatha eKhuseleko (i-SDS) kunye nayiphi na imvume efunekayo okanye izibhengezo.
