Ka nānā 'ana i ka pilikia

ʻO nā pōʻino olakino: ʻawaʻawa nui: hiki i ka inhalation ke hoʻoulu i nā hōʻailona ʻeha o ka ʻōpū hanu, epistaxis, hoarseness, atrophy o ka nasal mucosa, i kekahi manawa hānō a me ka cyanosis.Loaʻa paha nā maʻi koʻikoʻi i ka maʻi pneumonia.Hiki i ka hoʻoponopono waha ke hoʻoulu a hoʻopōʻino i ka ʻāpana digestive, e hoʻoulu ai i ka nausea, ka luaʻi ʻana, ka ʻeha ʻōpū, ka ʻōpū koko, a pēlā aku;I nā hihia koʻikoʻi, ʻike ʻia ka dyspnea, cyanosis, ka haʻalulu, ka pōʻino o ka ate a me ka hiki ʻole o ka renal.Nā hopena maʻi: contact dermatitis, chromium ulcer, rhinitis, nasal septum perforation a me ka ʻeha o ka ʻōpū hanu.

Hiki ke pahū: He carcinogen kēia huahana me ka ʻino a me ka huhū, hiki ke hoʻopau i ke kino o ke kanaka.

Nā hana kōkua mua

Pili i ka ʻili: wehe i nā lole i haumia a holoi pono i ka ʻili me ka wai kopa a me ka wai.

Hoʻopili i ka maka: e hāpai i nā lihilihi a holoi me ka wai kahe a i ʻole ka paʻakai maʻamau.E ʻike i ke kauka.

Inhalation: haʻalele koke i ke kahua i ka ea hou.E mālama i ka ʻōpū hanu ʻaʻole keakea.Inā pilikia kou hanu, hāʻawi i ka oxygen.Inā pau ka hanu ʻana, hāʻawi koke i ka hanu ʻana.E ʻike i ke kauka.

Ingestion: hoʻomaʻemaʻe me ka wai a holoi me ka wai a i ʻole 1% sodium thiosulfate solution.Hāʻawi mai iaʻu i ka waiū a i ʻole ka hua keʻokeʻo.E ʻike i ke kauka.

Nā hana pale ahi

ʻO nā hiʻohiʻona pōʻino: ikaika oxidant.Inā loaʻa ka waikawa ikaika a i ʻole ka wela kiʻekiʻe, hiki ke hoʻokuʻu ʻia ka oxygen e hoʻoikaika i ka puhi ʻana o nā mea ola.Hoʻopili ikaika ia me ka nitrate a me ka chlorate.Ke hui pū ʻia ka wai me ka sodium sulfide, hiki iā ia ke hana i ka hoʻopau ʻana.I ka hui ʻana a i ʻole hui pū me nā mea hoʻonaninani, nā mea hoʻohaʻahaʻa a me nā inflammables e like me ka sulfur a me ka phosphorus, aia kahi pilikia o ka puhi ʻana a me ka pahū.Loaʻa iā ia ka corrosiveness ikaika.

Nā huahana hoʻopau ʻino: hiki ke hana i ka uahi ʻawaʻawa.

Ke ala kinai ahi: hoʻohana i ka wai noe a me ke one e kinai i ke ahi.

Leakage lapaʻau pilikia

Lapaʻau ulia pōpilikia: hoʻokaʻawale i ka wahi i haumia a hoʻopaʻa i ke komo ʻana.Manaʻo ʻia e ʻaʻahu nā limahana lapaʻau ulia pōpilikia i nā maka lepo (nā maka piha piha) a me nā lole pale kinoea.Mai hoʻokuʻu i ka leakage e pili me nā organika, nā mea hoʻohaʻahaʻa a me nā inflammables.

Leaka liʻiliʻi: e hōʻiliʻili me ka ʻōpala maʻemaʻe i kahi pahu maloʻo, maʻemaʻe a uhi ʻia.

Ka nui o ka leakage: hōʻiliʻili a hana hou a lawe ʻia paha i kahi kahua lapaʻau no ka hoʻolei.

Ka mālama ʻana a me ka mālama ʻana

Nā hana mālama: pani ʻia ka hana, hoʻoikaika i ka ea.Pono nā mea hana e hoʻomaʻamaʻa kūikawā a mālama pono i nā kaʻina hana.Manaʻo ʻia e ʻaʻahu nā mea hoʻohana i ke ʻano puʻupuʻu uila lako ea kānana lepo respirator, polyethylene anti-virus a me nā mīkina lima.E mālama i ke ahi a me ke kumu wela.ʻAʻole puhi paka ma kahi hana.E pale i ka lepo.E hōʻalo i ka pilina me nā mea hoʻohaʻahaʻa a me nā waiʻona.I ka lawe ʻana, pono e hoʻouka ʻia a wehe māmā i mea e pale ai i ka pōʻino o ka pūʻolo a me ka pahu.Pono e ho'olako 'ia nā lako pale ahi o nā 'ano like 'ole a me ka nui a me ka leakage.Loaʻa paha nā mea pōʻino i loko o nā pahu hakahaka.ʻO ka mālama ʻana: mālama i loko o kahi hale kūʻai maloʻo, maloʻo a maikaʻi hoʻi.E mālama i ke ahi a me ke kumu wela.ʻAʻole ʻoi aku ka mahana o ka mālama ʻana ma mua o 35 ℃, a ʻo ka haʻahaʻa haʻahaʻa ʻaʻole ma mua o 75%.Hoʻopaʻa ʻia ka pūʻolo.Pono e mālama ʻokoʻa ʻia mai nā mea hoʻohaʻahaʻa a me nā ʻawaʻawa, a pono e pale ʻia ka waiho ʻana i hui ʻia.Pono e hoʻolako ʻia ka wahi mālama me nā mea kūpono e loaʻa ai ka leakage.
