Hei whakarei ake i te haumaru o ngā whare, kua whakamāramahia e Hong Kong ngā whakaritenga katoa mō te tukanga whakamahi ingā puranga whenua kua whakakanapahiaMe whiriwhiri ngā hua he matotoru te paparanga konutea ≥ 85 μm, ā, e tutuki ana i ngā paerewa GB/T 13912. Me whakahaere ngā rangahau matawhenua i mua i te hanganga, ā, me whakamahi ngā kaimahi whaimana i ngā taputapu motuhake mō te tāutanga paerewa, me te whakahaere kaha i te poutū me te hohonu o te tanumanga. I muri i te tāutanga, me whai whakamātautau kume me te pēhi me te manatoko i te pumau o te ahi. Kāore e whakaaetia kia uru atu ngā hua kāore i whaimana ki te papaanga hei karo i ngā tūponotanga haumaru mai i te pūtake.

Kua whakatūria e Hong Kong tētahi tikanga whakahaere mō te wā roangā puranga whenua kua whakakanapahia, e hiahia ana kia tirotirohia auautia ngā wāhanga e kitea ana, kia piki ake te auau i muri i te huarere kino, me te whakatika i te pakaru o te waikura me te paparanga konutea i te wā tika. I taua wā anō, whakatūria he pukapuka whakamahinga, whakamāramahia te rohe o runga o te roanga mahi 30-tau, me te whakahau kia whakakapia ngā puranga whenua kua pau te wā, kua pakaru rānei. Ka whakapakari anō hoki te kāwanatanga i ngā tirotiro motuhake me ngā whakangungu mō ngā kaimahi kia nui ake ai ō rātou painga ki te aukati i te waikura, te aukati ahi, me te pumau.
