He paerewa nui tēnei i roto i te umanga hanga e whakarite ana kia tutuki i ngā rauemi e whakamahia ana i roto i ngā whare ngā whakaritenga haumaru ahi. Engari he aha tonu te BS 476? He aha i hiranga ai?

Ko te BS 476 te whakarāpopototanga o te British Standard 476, ā, he raupapa whakamātautau hei aromatawai i te mahi ahi o ngā rauemi hanga whare. Ka aromatawaihia e ēnei whakamātautau ngā āhuatanga pēnei i te mura, te ngāwari ki te mura me te ātete ahi o ngā rauemi, tae atu ki ngā pakitara, ngā papa me ngā tuanui.

Ko te tikanga o tēnei me tutuki ngā rauemi e whakamahia ana i roto i te hanganga ki ngā paerewa haumaru ahi kua whakarārangihia i roto i te BS 476 kia mōhio ai kei te haumaru, kei te pakari hoki ngā whare ina pā mai he ahi.

Hei whakarāpopototanga, he paerewa nui te BS 476 e whai wāhi nui ana ki te whakarite i te haumaru ahi o ngā whare. Mā te whakamātautau ahi pakari o ngā rauemi hanga ka āwhina i te whakaiti i te mōrearea o ngā aituā ahi, ā, ka āwhina hoki ki te whakapai ake i te haumaru me te pakari whānui o te hanganga. He mea nui kia mārama, kia piri hoki te hunga katoa e whai wāhi ana ki te umanga hanga ki te BS 476 kia mōhio ai kei te hangaia ngā whare ki ngā paerewa haumaru ahi teitei rawa atu.
