ʻO ka pahuhopu o kēia palapala e hōʻemi i ka wehe ulia pōpilikia ʻana o nā kiwikā lima i nā ʻōnaehana hoʻomaʻalili ammonia.
Ma ke ʻano he ʻāpana o ka hoʻolālā kaohi ikehu, ua hoʻopuka ka International Ammonia Refrigeration Institute (IIAR) i kekahi mau ʻōlelo aʻoaʻo e pale aku i ka wehe ʻana o nā kiwikā lima i nā ʻōnaehana hoʻomaʻalili ammonia (R717).
ʻO ka mana mua o ka manaʻo i manaʻo ʻia-Nā Alakaʻi no ka hoʻomohala ʻana i nā hoʻolālā kaohi ikehu no nā kiwikā lima i nā ʻōnaehana hoʻomaʻalili ammonia-hiki i nā lālā IIAR ke kūʻai no $150, a hiki i nā lālā ʻole ke kūʻai no $300.
ʻO ke kaohi ʻana o ka valve manual e pili ana i ke kaohi ʻana o ka ikehu weliweli, kahi i kapa pinepine ʻia ʻo ke kaʻina hana lockout/tagout (LOTO). Wahi a ka pūnaewele ʻo University of Iowa Environmental Health and Safety, hiki i kēia ke pale i nā limahana mai ka ʻeha a make paha ma muli o ka hoʻāla ʻia ʻana a i ʻole ka hoʻokuʻu ʻia ʻana o ka ikehu i mālama ʻia i ka wā e mālama ai a hoʻoponopono hou i nā mīkini, nā kaʻina hana, a me nā ʻōnaehana.
Hiki i ka ikehu weliweli ke uila, hydraulic, pneumatic, mechanical, kemikala, thermal, a i ʻole nā kumu ʻē aʻe. "ʻO ka hahai ʻana i nā hana a me nā kaʻina hana LOTO kūpono hiki ke pale i nā limahana mai nā hoʻokuʻu ikehu ʻino," wahi a ka pūnaewele o ke Kulanui o Iowa.
Mai ka wā i hoʻokō ai ka US Occupational Health and Safety Administration (OSHA) i ke kānāwai kaohi ikehu weliweli (laka/papa inoa) i ka makahiki 1989, ua hoʻokō nā ʻoihana he nui i nā papahana kaohi ikehu LOTO. Akā, ua kau nui ʻia kēia mau mea ma ka ikehu uila a me ka mīkini weliweli; e like me IIAR, ʻaʻohe maopopo o ka ʻoihana HVAC&R i ka wehe ʻana o nā valves manual, ʻo ia ke kumu o nā kahe ammonia he nui.
ʻO ka pahuhopu o ke alakaʻi hou e "hoʻopiha i ka hakahaka o ka ʻoihana" a hāʻawi i nā mea nona a me nā mea hoʻohana o nā kiwikā manual R717 me nā ʻōlelo aʻoaʻo hana maikaʻi loa e pili ana i ka hoʻopili ʻana i nā hoʻolālā kaohi ikehu.
