LOTO- Igikorwa cyo kuvura ubushyuhe

Mu 2020, muri Leta Zunze Ubumwe za Amerika habaye impanuka yo kuvura ubushyuhe, yahitanye abakozi babiri. Impamvu ni uko inzira z'umutekano zo gufunga Tag Out (LOTO) na Restricted Space Code zitakurikijwe.

Iyi mpanuka itubwira ko gutunganya ubushyuhe ari inganda ziteje akaga cyane, gutunganya ubushyuhe ntibishobora gutandukanywa n'amazi, gaze, amashanyarazi, n'ibindi bintu biteje akaga biri hose. Hari ibikoresho bimwe na bimwe bidakoreshwa neza, uburangare, n'ibindi bishobora guteza akaga gakomeye. Uko kubungabunga ibidukikije n'ibisabwa mu bwiza birushaho gukomera, ibigo byinshi bigura kandi bigakoresha amatanura nyayo yo kuzimya umwuka, arimo umutekano w'amatanura akoresha umwuka udafite umwuka n'umutekano w'umwuka udafite umwuka. Iyi mpanuka idusubiza ku rundi rubanza. Impanuka yabaye saa cyenda n'igice za mu gitondo ku ya 17 Gicurasi 2001, ubwo umukozi ushinzwe kubungabunga yakoraga ku mugozi wa hydraulic mu itanura rikoresha umwuka udafite umwuka. Itanura rifunguye ku ruhande kandi rifite ikigega cyo kuzimya gifite umurambararo wa metero 1.5 n'ubujyakuzimu bwa metero 1.5. Iyo igikoresho gishyizwe mu gikoresho cyo kuzimya umuriro, itanura ryujujwemo gaze cyangwa azote aho kuba iy'umwuka udafite umwuka. Kugira ngo basane umugozi wa hydraulic, ikigega cya peteroli cyavanywemo amazi mu minsi itatu ishize maze moteri ishyirwa hasi mu kigega cyo kuzimya umuriro. Umukozi ushinzwe gusana yaguye mu kigega cy’amazi kirimo ubusa ku kazi maze umuyobozi we yumva ihamagara ry’ubutabazi maze yurira mu ziko kugira ngo agerageze kumufasha. Bagenzi be bumvise ihamagara ry’ubutabazi bageze aho byabereye basanga umukozi ushinzwe gusana aryamye kuri lift n’umuyobozi we aryamye iruhande rwe. Muri iki gihe, agakoresho ko kugenzura itanura karafunguye maze imiyoboro ya argon na azote irafunguka. Gusohora gazi akenshi bigenzurwa na valve ya solenoid mu gihe cyo gutunganya ubushyuhe. Ntibyasobanuwe neza impamvu byatangiye cyangwa ubwoko bwa gazi bwari bushyirwa mu itanura. Abatangabuhamya nyuma bavuze ko ishati yari mu kabati k’amashanyarazi yerekanaga gazi ya argon. Abakozi bo mu kigo gishinzwe gusana n’abashinzwe kugenzura ntibari bambaye ingofero cyangwa insinga z’umutekano, kandi igihe ishami rishinzwe kuzimya umuriro ryahageraga bitinze cyane kugira ngo ribajyane mu bitaro, raporo y’isuzuma ry’umurambo yavuze ko icyateye urupfu ari ukubura umwuka.

Loto, byitwa lockout-tagout. OSHA ni uburyo bukurikije OSHA bwo gukumira imvune z’umuntu binyuze mu gutandukanya cyangwa gufunga amasoko amwe n’amwe y’ingufu zishobora guteza akaga. Yakoreshejwe cyane ku isi, none ubu yagaragaye mu gihe gikwiye mu Bushinwa. Hariho kandi ibisobanuro bifatika mu Itegeko ry’Umutekano mu Gutunganya Umutekano. Hariho kandi ingingo zihariye mu gipimo cyonyine cy’igihugu gitegetswe mu rwego rwo gutunganya ubushyuhe GB 15735 2012, Ibisabwa ku Mutekano n’Isuku mu Gutunganya Ubushyuhe bw’Ibyuma. Intego yayo ni ukurinda abakozi kwangirika kw’ingufu z’imashini, bireba buri mukozi ukeneye kuvugana cyangwa gukorera hafi y’imashini cyangwa ibikoresho bifite cyangwa bibitse ingufu. Uburyo bwihariye ni ugufunga amashanyarazi mugihe ushyiramo ibikoresho byo gusukura \ by’ubuziranenge \ by’igenzura \ by’isuku, no kwerekana ko imirimo yo kubungabunga irimo gukorwa hamwe n’ikimenyetso mu gihe ingufu zidahari, no kugerageza nyuma yo gukora akazi kavuzwe haruguru.
