Self-Contained Breathing Apparatus (SCBA) inoita basa rakakosha mukuona kuchengetedzeka kwevanhu vanoshanda munzvimbo dzine njodzi uko mhando yemhepo inokanganiswa. Chimwe chakakosha cheSCBA inguva yekuzvimiririra - nguva iyo mushandisi anogona kufema zvakachengeteka kubva kumudziyo asati ada kuzadzazve kana kubuda munzvimbo ine ngozi.
Zvinhu Zvinokurudzira SCBA Autonomy Nguva:
1-Silinda Kukwanisa:Chinhu chikuru chinokanganisa nguva yekuzvidzivirira ndiko kugona kwemhepo kana oxygenhumburumbirayakabatanidzwa muSCBA.Cylinders inouya muhukuru hwakasiyana, uye hukuru hukuru hunopa nguva yakawedzerwa yekushanda.
2-Kufema Mwero:Mwero wekufema nemushandisi unokanganisa zvakanyanya nguva yekuzvitonga. Kushanda nesimba kwemuviri kana kushushikana kunogona kukwidza mitengo yekufema, zvichitungamira kukurumidza kushandiswa kwemhepo. Kudzidziswa kwakakodzera kubata kufema zvakanaka kwakakosha.
3-Kudzvinyirira uye Tembiricha:Shanduko mukumanikidza kwezvakatipoteredza uye tembiricha inokanganisa huwandu hwemhepo mukati mehumburumbira. Vagadziri vanotarisa zvinhu izvi muzvirevo zvavo kuti vape fungidziro yenguva yekuzvimiririra pasi pemamiriro akasiyana.
4-Kudzidzisa Kwemushandisi uye Kuranga: Kushanda kweSCBA hakubvi pakugadzirwa kwayo chete asiwo kuti vashandisi vakanyatsodzidziswa sei kuishandisa. Kudzidziswa kwakaringana kunovimbisa kuti vanhu vanoshandisa zvishandiso nemazvo, vachigonesa nguva yekuzvitonga mumamiriro ezvinhu epasirese.
5-Integrated Technologies:Mamwe emhando yepamusoro eSCBA anosanganisira emagetsi ekutarisa masisitimu. Aya matekinoroji anopa ruzivo rwenguva chaiyo nezve yasara mhepo inopihwa, ichibvumira vashandisi kubata yavo yekufema uye yekushanda nguva zvakanyanya.
6-Regulatory Standards:Kutevedzwa neindasitiri uye kuchengetedza zviyero kwakakosha. Vagadziri vanogadzira masisitimu eSCBA kuti asangane kana kudarika zviyero izvi, vachiona kuti nguva yekuzvitonga inoenderana nemitemo yekuchengetedza.
Kukosha Kwenguva Yekuzvimirira:
1-Emergency Response:Mumamiriro ezvinhu ekukurumidzira sekudzima moto kana mabasa ekununura, kuve nekunzwisisa kwakajeka kwenguva yekuzvimiririra kwakakosha. Inoita kuti vanopindura varonge zviito zvavo nemazvo uye vanova nechokwadi chekuti vanobuda munzvimbo dzine njodzi mweya usati wapera.
2-Kushanda Kushanda:Kuziva nguva yekuzvitonga kunobatsira masangano kuronga nekuita mashandiro zvakanyanya. Inobvumira kugovaniswa kwezviwanikwa zviri nani uye manejimendi mumamiriro ezvinhu apo vanhu vakawanda vari kushandisa SCBA panguva imwe chete.
3-Kuchengetedzwa Kwemushandisi:Nguva yekuzvimiririra yakabatana zvakananga nekuchengetedzeka kwevanhu vanoshandisa SCBA. Kunyatso fungidzira uye kutonga nguva yekuzvitonga kunoderedza njodzi yevashandisi vanopererwa nemhepo zvisingatarisirwi, kudzivirira njodzi dzinogona kuitika kana kukuvara.
Mukupedzisa, SCBA yekuzvitonga nguva inzvimbo ine mativi mazhinji inosanganisira zvese dhizaini yemidziyo uye maitiro emushandisi. Iyo yakakosha parameter inopesvedzera budiriro yekushanda munzvimbo dzine njodzi, ichisimbisa kukosha kwekuenderera mberi kudzidziswa, kutevedzera zviyero, uye kufambira mberi muhunyanzvi hwekusimudzira kuchengetedzwa nekubudirira.
