Hiki i kekahi mau keʻena ke koho e hoʻolako i nā limahana me nā mākaʻikaʻi oxygen pilikino a hoʻohana i kahi ʻōnaehana hoa i hiki ai i nā kānaka ke komo i loko o ka lumi cryogenic i ʻelua, e hōʻemi ana i ka manawa o ke kanaka hoʻokahi i loko o ka lumi i kēlā me kēia manawa.ʻO ia ke kuleana o ka ʻoihana e hoʻomaʻamaʻa i nā limahana ma ka ʻōnaehana mālama anu a me kāna mau mea hana a he nui ka poʻe e koho i nā limahana e hana i nā papa palekana nitrogen online.Pono nā limahana e ʻaʻahu i nā lako pale pilikino (PPE) kūpono e pale aku i ke kuni cryogenic, e like me ka pale maka, nā mīkina lima, nā kāmaʻa kūpono, a me ke kapa komo.Pono nā limahana a pau e hoʻomaʻamaʻa mua i ke ʻano o ka hana ʻana i ke kuni cryogenic, a he mea kūpono ke loaʻa kahi lako wai mehana ma kahi kokoke e hoʻomaʻemaʻe i ka ʻili inā loaʻa kahi kuni.
NO.4 Ka malama ana
ʻAʻohe wahi neʻe ka moku kaomi a me ka pahu LN2, ʻo ia ka mea e pono ai ka papa hana mālama makahiki.I loko o kēia, pono e nānā ʻia ke ʻano o ka hose cryogenic, a me nā mea e pono ai ke pani ʻia o nā pahu hoʻokuʻu palekana.Pono nā limahana e nānā mau ʻaʻole he wahi hau – ma ka ipu a i ʻole ma ka moku hānai – hiki ke hōʻike i kahi pilikia me ka ʻūhā.Me ka noʻonoʻo pono ʻana i kēia mau mea āpau, a me kahi papa hana mālama maʻamau, hiki i nā moku pressurized ke mau a hiki i 20 mau makahiki.
