Te kiore inhalation kukū paitini iti (TCLo): 109g/kg (rongoa mo 6~15d o te haputanga), meinga embryotoxicity me te pā te pūnaha musculoskeletal.
Panui mahi: mahi kati, whakakaha i te hau.Me whakangungu motuhake nga Kaihautu me te tino whai i nga tikanga whakahaere. E taunaki ana kia mau nga kaiwhakahaere ki te whakakakahu i nga respirators tātari whaiaro (hawhe kopare), he karumaru haumaru matū, kakahu mahi anti-static me te hinu rapa- karapu ātete.Kia matara atu i te ahi me nga puna wera, ka tino aukatia te kai paipa i te waahi mahi.Whakamahia nga punaha me nga taputapu whakamaarama-pahū.Aukati i nga kohu kia kore e rere ki roto i te hau o te waahi mahi.Kati te pa atu ki nga waikura, waikawa, turanga, haukoi.
