- E hoʻouka i ka pahu pale
He paʻakikī ke kaiapuni lalo o nā mine lanahu. ʻAʻole wale ʻia nā mea hana like ʻole e hōʻiliʻili ʻia, akā aia pū kekahi. Inā hoʻokumu ʻia nā arcs a me nā ʻulaʻula i ka wā o ka hana ʻana o nā mea uila no nā kumu like ʻole, hiki mai ke ahi a me nā pahū. Hoʻohana pono ʻia kahi mea pale i kapa ʻia he pahu pale ahi no ka pale ʻana i nā mea uila a me nā mea uila holoʻokoʻa. Ma hope o ka hoʻokomo ʻana i kēia casing flameproof, e hoʻokaʻawale ʻia nā arcs, sparks a me nā pahū i hana ʻia e nā ʻāpana uila a i ʻole nā mea hana i loko a ʻaʻole e hoʻopilikia i ke kaiapuni o waho a me nā mea hoʻopuni. He kiʻekiʻe ka hoʻohana ʻana o kēia ʻano hana i ka mine lanahu ma lalo o nā mīkini kaʻa a me nā hoʻololi uila kiʻekiʻe a haʻahaʻa, a ʻoi aku ka maikaʻi o ka hopena.
- E hoʻohana i nā kaapuni palekana i loko
ʻO nā kaapuni palekana maoli kahi manaʻo e puka mai ana o nā kaapuni palekana, ʻo ia ka mea e pili ana i ka ʻoiaʻiʻo ʻoiai inā he pōkole pōkole a i ʻole ka uila i ka wā o ka hana o ke kaapuni, ʻaʻole lawa ka degere e puhi a hoʻopau i nā mea puhi ahi a me nā kinoea puhi. I kēia manawa, ua hoʻohana nui ʻia kēia ʻano kūikawā o ka pōʻai palekana i ka ikehu, textile a me nā ʻoihana ʻē aʻe o koʻu ʻāina. Hiki i nā kaapuni palekana ke hana paʻa ma waena o nā wahi pōʻino a me nā wahi palekana i nā ʻōnaehana uila. ʻO nā hiʻohiʻona koʻikoʻi o nā kaʻa kaʻa intrinsically palekana ʻo ia ka liʻiliʻi o kā lākou mau ʻāpana o kēia manawa a me ka volta, no laila ua kūpono lākou no nā mea ana liʻiliʻi a me nā ʻōnaehana laina kamaʻilio i nā mina lanahu.
- E lawe i nā hana hoʻonui palekana
ʻO kēia ʻano hana e pili ana i ka lawe ʻana i nā mea pale i manaʻo ʻia no nā hiʻohiʻona o nā mea uila like ʻole a me nā ʻōnaehana kaapuni e hoʻopuka ai i nā huna ahi a me nā pōʻino palekana ʻē aʻe. ʻO nā mea nui e pale ʻia e pili ana i nā pōkole pōkole, overheating, sparks, arcs, etc., a ʻo nā ʻano kumu nui i hoʻohana ʻia e hoʻomaikaʻi i ka ikaika insulation a me ka hana maikaʻi ʻana i ka hoʻomaha. Hoʻohana pinepine ʻia kēia mau hana hoʻonui palekana i nā mea hoʻololi a me nā kaʻa i nā mine lanahu, hiki ke hoʻomaikaʻi maikaʻi i ka pae palekana o nā lako uila ponoʻī.
- Mea ʻoki ʻoki ʻakomi
Ma ka hoʻokomo ʻana i nā mea ʻike ma nā wahi kūpono o nā lako uila a me nā ʻōnaehana uila, ke ʻike ʻia nā pōkole pōkole, ka wela nui, a me nā ʻālohilohi, e ʻoki ʻoki ʻia ka mana a me ke kaapuni. ʻO ka pōmaikaʻi o kēia ala ʻo ia ka hiki ke hoʻololi pono i ka nānā ʻana i ka manawa maoli o nā lako uila a hana i ka mālama pono i ka manawa mua o ka pilikia. Ma kēia ala, hiki ke ʻoki pinepine ʻia ka lako mana ma mua o ke kumu wela a hoʻāla ʻia nā huna ahi i ka lepo lanahu a me ke kinoea i loko o ke kaiapuni e pale ai i ka hiki ʻana mai o nā pahū.
