Nā ʻoihana Petrochemical Lockout Tagout

Aia nā mea weliweli a me ka ikehu weliweli (e like me ka ikehu uila, ka ikehu kaomi, ka ikehu mīkini, a me nā mea ʻē aʻe) i hiki ke hoʻokuʻu hewa ʻia i loko o nā lako hana o nā ʻoihana petrochemical. Inā paʻa pono ʻole ka hoʻokaʻawale ikehu i ke kaʻina hana o ka nānā ʻana a me ka mālama ʻana a me ka hoʻomaka ʻana a me ka pani ʻana o nā lako, hiki ke loaʻa nā ulia (nā hanana) ma muli o ka hoʻokuʻu hewa ʻana o nā mea weliweli a me ka ikehu.

Ua wehe piha ʻia kahi kiwikā laina hānai umu "5.29" i loko o kahi ʻoihana ʻo olefins ma ke keʻena ʻo 7 #, ua hōʻoia ʻia ua wehe ʻia ka pā flange makapō e nā limahana lawe. Inā ʻaʻole i pau ka hoʻololi ʻana i ka pā makapō, ua wehe ka mea lawelawe i ka kiwikā komo. ʻAʻole i pani ka honua o ka naphtha māmā i ka 1.3 MPa mai ke kaomi māmā naphtha māmā mai ka flange leak. He nui ka ʻaila gasified a me ke kinoea i loaʻa i ke ahi ākea i loko o ka umu, a i ʻole ka pahū ʻana o ka uila i loko o ke kumu wela kiʻekiʻe, a laila ua hoʻoulu i ke ahi, a laila ua make he 1, 5 mau ʻeha koʻikoʻi, 8 mau ʻeha liʻiliʻi.
Ma kēia ulia, ʻaʻohe kaohi hoʻokaʻawale kūpono no nā mea weliweli i ke kaʻina hana o ka hoʻomaka a me ka hoʻōki ʻana o ka hāmeʻa.
Pōʻino ahi a me ka pahū ʻana o ka mea hana butadiene rubber ma kahi ʻoihana ma Malaki 15

Ua lawe ka mea hoʻokele hana ʻole o kahi ʻoihana petrochemical i ka pilikia o ka hoʻokaʻawale ʻana i ka flange mea hana i hoʻopili ʻia i ka valve e hoʻomaʻemaʻe i ka plug me ka ʻole o ka pani piha ʻana i ka valve o ke kiko kaomi pae kinoea o ka mika pae wai hoʻoili mamao i loko o ka hale holoi alkali, e hopena ana i ka nui o ka leakage mea i loko o ka hale kiaʻi, a ʻo ka mea i puʻu koke ʻia e hoʻolaha koke e hana i ke kinoea pahū. Ua hana ʻia ka flashover ma hope o ka ʻāpana ea ea ʻaʻole pahū e kau ana ma ka paia ʻākau o ka substation ma ka ʻaoʻao hema o ka ʻāpana condensing, a laila hoʻoulu i ka pahū a me ke kuni kokoke i ka loko wai a me ka lumi pamu ma ka ʻaoʻao komohana o ka hale holoi alkali, e hopena ana i ka make ʻana o 1 a me 5 mau ʻeha. ✍ ma kēia ulia, ʻaʻohe ʻike kūpono, hoʻokaʻawale a me ka kaohi no nā mea weliweli a me ka ikehu i loko o ka pipeline hāmeʻa, no laila hana kū ʻole i ke kānāwai a me ka pilikia.
