Whakatupato mo te whakamahi hua
1. Hau parepare: Kia whai whakaaro ki te ma o te hau whakamarumaru, a ko te ōwehenga ranunga hau e taunakitia ana ko Ar+1-3%O2.
2.Te rere o te hau: 20-25L / min.
3.Elongation maroke: 15-25mm.
4.Me tino tango i te paparanga waikura, te makuku, te hinu, te puehu, me etahi atu i runga i te waahanga whakapiri.
5. I te wa o te weriweri o waho, ka nui ake te tere o te hau i te 1.5m/s, me tango nga tikanga parepare hau, me mahi nga mahi aukati hau e tika ana kia kore ai e puta nga pupuhi.
Ko nga whakaaro i runga ake nei mo te tohutoro anake, a ko te tino ahuatanga ka kaha i roto i nga mahi motuhake.Mena e tika ana, me whakahaere tohu tohu i mua i te whakatau i te mahere whakaahuru.
