1. Hiki ke ho'ohana 'ia ka carbon dioxide e kinai i ke ahi a he mea ho'opau ma'amau.I loko o ka ʻoihana kemika, he mea nui ka carbon dioxide a hoʻohana ʻia i nā mea nui e hana ai i ka lehu soda (Na2CO3), baking soda (NaHCO3), urea [CO(NH2)2], ammonium bicarbonate (NH4HCO3), pigment lead white. [Pb(OH)2 2PbCO3] etc.;
2. Ma ka oihana mama, pono ke kalapona kalapona no ka hana ana i na mea inu kalapona, pia, mea inu palupalu, a pela aku.
3. He mea hoʻoikaika maikaʻi ia no ka hanu kanaka.Hoʻoulu ʻo ia i ka hanu ma o ka hoʻoulu ʻana i nā mea hoʻokipa kemika ma waho o ke kino kanaka.Inā hoʻomaha ke kanaka i ka oxygen maʻemaʻe no ka manawa lōʻihi, ua haʻahaʻa loa ke kalapona kalapona i loko o ke kino, hiki ke hoʻopau i ka hanu.No laila, ma ke kino, hoʻohana ʻia ke kinoea hui ʻia o 5% carbon dioxide a me 95% oxygen i ka mālama ʻana i ka make ʻana o ka carbon monoxide, ke kau ʻana, ka haʻalulu, ka alkalosis a me ka anesthesia.Hoʻohana nui ʻia ka cryosurgery carbon dioxide wai;
4. Ka mālama ʻana i ka palaoa, nā huaʻai a me nā mea kanu.Ma muli o ka nele o ka oxygen a me ka hopena pale o ka carbon dioxide pono'ī, hiki i ka meaʻai i mālama ʻia me ka carbon dioxide hiki ke pale pono i ka ulu ʻana o ka bacteria, nā ʻōpala a me nā iniseti i loko o ka meaʻai, pale aku i ka pōʻino a me ka hana ʻana o nā peroxides e pōʻino i ke olakino, a hiki ke mālama a mālama i ka ʻono mua o ka meaʻai.ʻai meaʻai.ʻAʻole hiki ke kalapona i nā koena lāʻau a me ka haumia o ka lewa i loko o nā kīʻaha.ʻO ka hoʻohana ʻana i ka carbon dioxide i loko o ka hale waihona raiki no 24 mau hola hiki ke pepehi i 99% o nā iniseti;
5. Ma ke ʻano he extractant.Hoʻohana maʻamau nā ʻāina ʻē i ka carbon dioxide no ka meaʻai a me nā mea inu.ʻO ka hana a me ka unuhiʻana i nāʻaila, nā meaʻala, nā lāʻau lapaʻau, a pēlā aku;
6. Ke hoʻohana nei i ka carbon dioxide a me ka hydrogen e like me nā mea maka, hiki iā ia ke hana i ka methanol, methane, methyl ether, polycarbonate a me nā mea kemika ʻē aʻe a me nā wahie hou;
7. Ma keʻano he mea hoʻoheheʻeʻaila, hiki iā ia ke hoʻokuʻu i kaʻaila a hoʻonui i ka hoʻihoʻiʻana i kaʻaila;
8. ʻAʻole hiki ke pale wale i ka hoʻoheheʻe ʻana o ka ʻili metala, akā e hoʻonui i ka wikiwiki o ka welding ma kahi o 9 mau manawa.
