Whakatupato
Mahinga Whakatupatotanga: Ko tenei taputapu ka pangia ki te kino na te tukunga hiko (ESD).
Ka tino taunakitia he taiao kore utu.Whaia nga aratohu e ai ki nga tikanga ESD tika.
Haumaru Taiaho: Ko te iraruke e tukuna ana e nga taputapu laser he kino ki nga kanohi tangata.A ape i nga kanohi e pa ana ki te rauropi tika, arataki ranei.
