He aha ka mālama?

Kūʻai aku i loko o kahi hale hoʻomaha maloʻo a me ka maloʻo.
Ahi, ka wai a me ka pale o ka lā.
E mālama i nāʻano aloha a me nā wela wela.
Pale mai ka lā pololei.
Ua hoʻopaʻaʻia ka uku.
E mālamaʻia ia mai hohonu loa,ʻaʻole e hoʻokaʻawaleʻiaʻia.
Hāʻawi i nā mea kaua ahi ahi e pili ana i nāʻano kūpono a me nā nui.
E hoʻomākaukauʻia nā mea kūpono e loaʻa i ka leakage.
ʻO nā ana kōkua mua

E hoʻopili i kaʻili: E holoi holoi me ka wai a me ka wai. E kiʻi i ka mālama olakino.
E nānā i nā maka maka: E wehe i nā nalids a holoi i ka wai e kahe ana i ka wai no 15 mau minuke. E kiʻi i ka mālama olakino.
Inhalation: waiho i ka pūnaewele i ka ea hou. Hāʻawi i ka oxygen i ka wā paʻakikī ke hanu. Ke kū nei ka hanuʻana, lawe koke i ka hanu kūlohelohe. E kiʻi i ka mālama olakino.
Ingestion: No ka poʻe e lawe i ka hewa, inu i kahi nui o ka wai mahana e hoʻonāukiuki i ka luaʻi. E kiʻi i ka mālama olakino.
