Aʻo ʻo OSHA i nā limahana mālama e laka, hōʻailona, a mālama i nā kumu ikehu weliweli.ʻAʻole ʻike kekahi poʻe pehea e hana ai i kēia kaʻina, ʻokoʻa kēlā me kēia mīkini.Kiʻi kiʻi kiʻi
Ma waena o nā poʻe e hoʻohana ana i kēlā me kēia ʻano mea hana ʻoihana,lockout/tagoout (LOTO)ʻaʻohe mea hou.Inā ʻaʻole e hemo ka mana, ʻaʻohe mea e ʻaʻa e hana i kekahi ʻano o ka mālama maʻamau a i ʻole e hoʻāʻo e hoʻoponopono i ka mīkini a i ʻole ka ʻōnaehana.He koi wale kēia o ka noʻonoʻo maʻamau a me ka Occupational Safety and Health Administration (OSHA).
Ma mua o ka hana ʻana i nā hana mālama a hoʻoponopono paha, maʻalahi ka wehe ʻana i ka mīkini mai kona kumu mana-ʻo ka mea maʻamau ma ka hoʻopau ʻana i ka mea hoʻokele kaapuni-a hoʻopaʻa i ka puka o ka panel breaker.ʻO ka hoʻohui ʻana i kahi lepili e ʻike ai i nā ʻenehana mālama ma ka inoa he mea maʻalahi hoʻi.
Inā ʻaʻole hiki ke laka ʻia ka mana, hiki ke hoʻohana wale i ka lepili.I kēlā me kēia hihia, inā me ka laka a ʻaʻole paha, hōʻike ka lepili i ka holomua o ka mālama ʻana a ʻaʻole i hoʻohana ʻia ka hāmeʻa.
Akā naʻe, ʻaʻole kēia ka hopena o ka hailona.ʻO ka pahuhopu holoʻokoʻa ʻaʻole ia e wehe wale i ke kumu mana.ʻO ka pahuhopu e ʻai a hoʻokuʻu paha i nā ikehu pōʻino a pau-ma nā huaʻōlelo OSHA, e kāohi i ka ikehu weliweli.
Hōʻike ka ʻili maʻamau i ʻelua mau pōʻino pōkole.Ma hope o ka pio ʻana o ka pahi, e hoʻomau ka holo ʻana o ka pahi pahi no kekahi mau kekona, a e kū wale nō ke pau ka manawa i mālama ʻia i loko o ke kaʻa.E wela ka maka no kekahi mau minuke a pau ka wela.
E like me nā ʻōpala e mālama ai i ka ikehu mechanical a me ka wela, ʻo ka hana o ka holo ʻana i nā mīkini ʻenehana (electric, hydraulic a pneumatic) hiki ke mālama i ka ikehu no ka manawa lōʻihi. ke kaapuni, hiki ke mālama ʻia ka ikehu no ka manawa lōʻihi kamahaʻo.
Pono nā mīkini ʻenehana like ʻole e hoʻopau i ka ikehu.Hiki i ke kila kila AISI 1010 ke pale i nā ikaika wili a hiki i ka 45,000 PSI, no laila, pono nā mīkini e like me nā paʻi paʻi, nā kuʻi, nā kuʻi, a me nā piʻi paipu e hoʻouna i ka ikaika i nā ʻāpana o nā tona.Inā pani ʻia a wehe ʻia ke kaapuni e hoʻohana ana i ka ʻōnaehana hydraulic pump, hiki i ka ʻāpana hydraulic o ka ʻōnaehana ke hāʻawi i 45,000 PSI.Ma nā mīkini e hoʻohana ana i nā ʻōpala a i ʻole nā lau, ua lawa kēia e ʻoki a ʻoki paha i nā lālā.
ʻO kahi kaʻa kaʻa paʻa me ka bakeke i ka lewa e like me ka pōʻino e like me ka pahu kaʻa paʻa ʻole.E wehe i ke kīpē hewa a e lawe ka umekaumaha.Pēlā nō, hiki i ka ʻōnaehana pneumatic ke mālama i ka ikehu nui ke pio.Hiki ke hoʻopaʻa ʻia i ka 150 amperes o kēia manawa.Ma lalo o 0.040 amps, hiki i ka puʻuwai ke ho'ōki i ka paʻi.
ʻO ka hoʻokuʻu pono ʻana a i ʻole ka hoʻopau ʻana i ka ikehu kahi hana nui ma hope o ka hoʻopau ʻana i ka mana a me LOTO.ʻO ka hoʻokuʻu palekana a i ʻole ka ʻai ʻana i ka ikehu weliweli e pono ai ka hoʻomaopopo ʻana i nā kumu o ka ʻōnaehana a me nā kikoʻī o ka mīkini e pono e mālama a hoʻoponopono ʻia.
ʻElua ʻano o nā ʻōnaehana hydraulic: ka puka hāmama a me ka loop pani.I loko o kahi ʻenehana ʻoihana, ʻo nā ʻano pāpaʻi maʻamau he mau gears, vanes, a me nā pistons.Hiki i ka cylinder o ka mea hana holo ke hana hoʻokahi a i ʻole pālua.Hiki i nā ʻōnaehana hydraulic ke loaʻa i kekahi o nā ʻano valve ʻekolu-ka mana kuhikuhi, ka mana kahe, a me ka mana kaomi-ʻo kēlā me kēia ʻano he nui nā ʻano.Nui nā mea e hoʻolohe ai, no laila pono e hoʻomaopopo pono i kēlā me kēia ʻano ʻāpana e hoʻopau i nā pilikia pili i ka ikehu.
Ua ʻōlelo ʻo Jay Robinson, ka mea nona a me ka pelekikena o RbSA Industrial: "Hiki ke alakaʻi ʻia ka mea hana hydraulic e kahi pahu pani pani piha.""Wehe ka valve solenoid i ka valve.Ke holo nei ka ʻōnaehana, kahe ka wai hydraulic i nā mea hana ma ke kaomi kiʻekiʻe a i ka pahu i ka haʻahaʻa haʻahaʻa, "wahi āna.."Inā hoʻopuka ka ʻōnaehana i ka 2,000 PSI a ua pio ka mana, e hele ka solenoid i ke kūlana waena a kāpae i nā awa āpau.ʻAʻole hiki ke kahe ka aila a kū ka mīkini, akā hiki i ka ʻōnaehana ke loaʻa i ka 1,000 PSI ma kēlā me kēia ʻaoʻao o ka valve.
