Storage
Chengetedzo yekufambisa: usati watakurwa, tarisa kana mudziyo wekurongedza wakwana uye wakavharwa, uye ona kuti mudziyo haubvire, kudonha, kudonha kana kukuvara panguva yekufambisa.Izvo zvinorambidzwa zvachose kusanganiswa neasidhi, oxidants, zvokudya uye zvokudya zvinowedzera.Panguva yekufambisa, mota dzekufambisa dzichange dzakashongedzerwa nemhando dzinoenderana uye huwandu hwemidziyo yekudzimisa moto uye inodonha yekubvisa midziyo yekurapa emergency.Uye inofanirwa kuchengetedzwa kubva kuchiedza chezuva, mvura uye tembiricha yepamusoro uye inofanirwa kutyaira zvinoenderana nenzira yakatarwa, uye usagare munzvimbo dzekugara uye nzvimbo dzine vanhu vakawanda;
Kuchengetedza Kuchengetedza
Chitoro chakavharwa munzvimbo inotonhorera uye ine mhepo yekuchengetera yakaparadzana kubva kune oxidant uye alkali uye dzivirira musanganiswa kuchengetedza.Chengetedza kure nemoto nekupisa uye nechiedza chezuva chakanangana nechiedza chezuva. inofanira kuchengetwa midziyo yekudzimisa moto yemhando dzakasiyana-siyana uye huwandu huchapihwa.Nzvimbo yekuchengetera inofanirwa kunge yakashongedzerwa nezvinhu zvakakodzera kuti ive nekudonha;
Packing Precautions
Yakajairika kesi yemapuranga kunze kwebhodhoro reampoule;yakajairika yemapuranga kesi kunze kwe threaded girazi bhodhoro, iron cap yakatsikirirwa girazi bhodhoro, epurasitiki bhodhoro kana simbi dhiramu (can);bhokisi rakazara rezasi relatisi, fiberboard bhokisi kana plywood bhokisi kunze kweshinda yegirazi bhodhoro, bhodhoro repurasitiki kana tinplate barrel (can).
