Midziyo yekuvharira mavharuvhu zvinhu zvakakosha mukuona kuchengetedzeka kwebasa, kunyanya mumaindasitiri uko kuburitswa kwesimba rine njodzi kuri kunetseka. Chimwe chiitiko chakakosha chakaratidza kukosha kwemidziyo iyi chakaitika muna 2005 pafekitori yemakemikari muTexas. Vharuvhu yakavhurwa netsaona panguva yekugadzirisa nguva dzose, zvikaita kuti kuburitswa kwemagasi ane chepfu uye kuputika kwakaipisisa. Chiitiko ichi chakasimbisa kukosha kwemaitiro akasimba ekuvharira/kuburitsa mavharuvhu (LOTO) kudzivirira kushanda kwemuchina nemasisitimu zvisina mvumo kana netsaona. Tichifunga nezveruzivo urwu, ngationgororei kuti michina yekuvharira mavharuvhu chii, mashandisirwo ayo, uye nei ichikosha.
Midziyo yekuvharira mavharuvhu inokosha zvikuru pakuona kuti michina nemidziyo zvinoramba zvisina simba rakawanda panguva yekugadzirisa nekugadzirisa. Nekukiya vharuvhu panzvimbo, michina iyi inodzivirira kuburitswa kwesimba rine njodzi netsaona, zvichidzivirira vashandi kubva mukukuvadzwa kunogona kuitika.

Midziyo yekuvharira mavharuvhu inzira dzekuchengetedza dzakagadzirirwa kuparadzanisa masosi esimba kuitira kuti michina nemidziyo zvisakwanise kushanda panguva yekugadzirisa kana kugadzirisa. Midziyo iyi inouya mumhando dzakasiyana uye inoshandiswa mumaindasitiri uko kuburitswa kwesimba rine njodzi kusingatarisirwi kunogona kukonzera njodzi huru dzekuchengetedza. Mhando dzakajairika dzinosanganisira kuvharira mavharuvhu ebhora, kuvharira mavharuvhu egedhi, uye kuvharira mavharuvhu ebhururu.
Chinangwa chikuru chemidziyo yekukiya mavharuvhu ndechekupa chipingamupinyi chemuviri chinodzivirira vharuvhu kuti isashandise. Chipingamupinyi ichi chinoita kuti vharuvhu irambe yakachengeteka, ingave yakavhurika kana yakavharwa, zvichienderana nezvinodiwa nemaitiro ekugadzirisa. Pamusoro pekukiya chaiko, michina iyi inowanzo sanganisira nzira yekuisa matag inopa ruzivo rwakakosha nezvemamiriro ekukiya, senge zita remunhu ane mhosva yekukiya uye zuva rayakashandiswa.
Mhando dzeMavharuvhu Ekuvhara Mavharuvhu
Kune mhando dzakasiyana dzemidziyo yekuvharira mavharuvhu, imwe neimwe yakagadzirirwa kugadzirisa magadzirirwo nemashandisirwo akasiyana emavharuvhu. Kunzwisisa mhando dzakasiyana dzemidziyo kunogona kubatsira pakusarudza mudziyo wakakodzera zvinodiwa:
Kuvharirwa kweVharuvhu Yebhora
Mavharuvhu ebhora akagadzirwa kuti akwane pamusoro pemubato wemavharuvhu ebhora, zvichidzivirira kuti mubato usatenderedzwe. Mavharuvhu aya anowanzo gadziriswa kuti akwane saizi dzakasiyana dzemubato. Anoshandiswa zvakanyanya nekuti mavharuvhu ebhora anowanikwa munzvimbo dzakawanda dzemaindasitiri.
Mudziyo uyu unoshanda nekufukidza mubato nechinhu chinodzivirira chakavharwa nekiyi. Vashandi vane mvumo chete vane kiyi kana musanganiswa ndivo vanogona kubvisa kiyi, vachiona kuti vharuvhu haigone kuvhurwa kana kuvharwa nemaune. Rudzi urwu rwekuvharirwa kunze runonyanya kubatsira muzviitiko zvinosanganisira mvura kana magasi, uko kuvhurika netsaona kunogona kukonzera kudururwa, kudonha kwemvura, kana kuwedzera kwesimba.
