| Ubutyhefu. | Uncedo yokuqala. Amanqaku okutshisa okuzenzekelayo (135): Hambisa isigulane kwindawo enomoya omtsha ukuze ufumane unyango. Ukuba isigulana siyayeka ukuphefumla, mnike ukuphefumla okwenziwayo. Ukuba ukuphefumla kunzima, nika ioksijini. Susa kwaye ubeke yedwa iimpahla kunye nezihlangu ezingcolileyo. Ukuba ulusu okanye amehlo adibana nento, ngokukhawuleza uyigungxule ngamanzi kangangemizuzu engama-20 ubuncinane. Gcina isigulana sifudumele kwaye sithule. Qinisekisa ukuba abasebenzi bezonyango bayaluqonda ulwazi lokhuseleko lomntu olunxulumene nale nto kwaye banikele ingqalelo ekukhuseleni kwabo. Ukusabela ngamanzi (kukhupha igesi enokutsha) (138): Hambisa isigulane kwindawo enomoya omtsha ukuze ufumane unyango. Ukuba isigulana siyayeka ukuphefumla, mnike ukuphefumla okwenziwayo. Ukuba ukuphefumla kunzima, nika ioksijini. Susa kwaye ukhuphe impahla kunye nezihlangu ezingcolileyo. Ukuba ulusu okanye amehlo adibana nento, ngokukhawuleza uyigungxule ngamanzi kangangemizuzu engama-20 ubuncinane. Gcina isigulana sifudumele kwaye sithule. Qinisekisa ukuba abasebenzi bezonyango bayaluqonda ulwazi lokhuseleko lomntu olunxulumene nale nto kwaye banikele ingqalelo ekukhuseleni kwabo. | |
| Iingozi zempilo. | Intsimbi yeBarium iphantse ingabi netyhefu. I-soluble barium salts ezifana ne-barium chloride, i-barium nitrate, njl., Inokuthi ifakwe kwaye ibangele i-poisoning enzulu, kunye neempawu zokucaphuka kwendlela yokugaya, ukukhubazeka kwemisipha okuqhubekayo, ukubandakanyeka kwe-myocardial, i-potassium yegazi ephantsi, njalo njalo. Ukuphefumla izixa ezikhulu ze-soluble barium compounds kunokubangela i-acute barium poisoning, ukusebenza kufana netyhefu yomlomo, kodwa ukusabela kokugaya kukhanya. Ukubonakaliswa kwexesha elide kwi-barium. Abasebenzi abanokuvela ixesha elide kwiikhompawundi ze-barium banokuthi bahlupheke ngenxa ye-salivation, ubuthathaka, ukuphefumla, ukudumba kunye nokukhukuliseka kwe-mucosa yomlomo, i-rhinitis, i-tachycardia, ukunyuka kwegazi kunye nokulahlekelwa kweenwele. Ukuphefumla ixesha elide kwi-insoluble barium compounds kunokubangela i-barium pneumoconiosis.
