Ko te whāinga o tēnei tuhinga he whakaiti i te whakatuwheratanga tūpono o ngā takirere ā-ringa i roto i ngā pūnaha pouaka whakamātao haukini.
Hei wāhanga o te mahere whakahaere pūngao, i whakaputa te International Ammonia Refrigeration Institute (IIAR) i ētahi taunakitanga hei ārai i te whakatuwheratanga tūpono o ngā takirere ā-ringa i roto i ngā pūnaha pouaka whakamātao ammonia (R717).
Ko te putanga tuatahi o te tono—Ngā Aratohu mō te whakawhanake i ngā mahere whakahaere pūngao mō ngā takirere ā-ringa i roto i ngā pūnaha whakamatao haukini—ka taea e ngā mema o te IIAR te hoko mō te $150, ā, ka taea e te hunga ehara i te mema te hoko mō te $300.
Ko te whakahaere o te takirere ā-ringa e pā ana ki te whakahaere i te pūngao morearea, e kiia ana ko te tikanga raka/taki (LOTO). E ai ki te paetukutuku Hauora me te Haumaru Taiao o Te Whare Wānanga o Iowa, ka taea e tēnei te tiaki i ngā kaimahi mai i te whara, te mate rānei i te whakahohenga tūpono, i te tukunga rānei o te pūngao kua rongoatia i te wā e tiaki ana, e whakatika ana rānei i ngā mīhini, ngā tukanga, me ngā pūnaha.
Ka taea e te pūngao mōrearea te hiko, te waipēhi, te hauhautanga, te mīhini, te matū, te wera, me ētahi atu pūtake. "Mā te whai i ngā tikanga me ngā tikanga LOTO tika ka taea te tiaki i ngā kaimahi mai i ngā tukunga pūngao kino," te tāpiri a te paetukutuku o Te Whare Wānanga o Iowa.
Mai i te wā i whakatinanahia ai e te US Occupational Health and Safety Administration (OSHA) te ture whakahaere pūngao morearea (raka/rārangi) i te tau 1989, he maha ngā ahumahi kua whakatinana i ngā kaupapa whakahaere pūngao LOTO. Engari ko te nuinga o ēnei e aro ana ki te pūngao hiko me te pūngao miihini morearea; e ai ki te IIAR, kāore i te mārama te umanga HVAC&R mō te whakatuwheratanga tūpono o ngā takirere ā-ringa, koinei te take o te maha o ngā turuturu haukini.
Ko te whāinga o te aratohu hou he "whakakī i te āputa o te umanga" me te whakarato ki ngā kaipupuri me ngā kaiwhakahaere o ngā takirere ā-ringa R717 ngā tohutohu mahi pai mō te whakamahi i ngā mahere whakahaere pūngao.
