Panui mo te kawe waka: I te wa e kawe ana, me whakauru te waka kawe ki nga taputapu patu ahi me nga taputapu maimoatanga ohorere leakage o te momo me te rahinga e rite ana. He pai ki te kawe i te ata me te ahiahi i te raumati.Ko te taraka (tank) taraka e whakamahia ana mo te kawe me whai mekameka whenua, a ka taea te whakatu i tetahi wehenga poka ki roto i te tank hei whakaiti i te ru me te hiko pateko.Ka tino aukatia ki te whakauru me te kawe ki nga oxidants, waikawa, alkalis, halogens, matū kai, me etahi atu. I te wa e kawe ana, me whakamarumaru mai i te ra o te ra, te ua, me te pāmahana teitei. I te wa e noho ana, noho matara atu i te ahi, nga puna wera me nga waahi teitei.
