Whakaahuatanga Poto:

Dicyandiamide

Te paura tioata ma.Ko te whakarewatanga i roto i te wai ko te 2.26% i te 13°C,Ko te whakarewatanga teitei i roto i te wai wera.I te wa ka whakapohehehia te wairewa wai i te 80 °C, ka puta te hau haukini. Ina te whakarewatanga i roto i te waiwaro tino (C2H5OH) me te etera he 13 °C,he 1.26% me te 0.01%.Ka whakarewahia i roto i te haukini wai, te wai wera, te waiwaro, te acetone hydrate, te dimethylformamide, te kore e rewa i roto i te etera, e kore e rewa i roto i te benzene me te chloroform.Te kiato whanaunga (d254) 1.40.Ira whakarewa 209.5 ℃.Pumau ina maroke.Kaore e wera.He iti te paitini, te horopeta whakamate (kiore, waha)>4000mg/kg.Ko te 5mg/m³ te kukū mōrahi e whakaaetia ana ki te hau.

Nga mahi patu ahi

He kaha te tauhohenga ki te haukinia pākawa, te pāhare pāporo pūhaumāota me ō rātou tai.Whakaputaina he pahūtanga. Ka pirau na te wera nui, ka puta he kohu tino paitini o te cyanide me te hauota waikura.

Nga hua ngingiha morearea

hauota waikura, hauwai hauwai.

Tikanga patu ahi

Me mau nga kaipatu ahi i nga respirator tātari (te kanohi kanohi kapi) me nga respirator wehe, me mau kakahu whakamarumaru tinana katoa me nga kakahu whakamarumaru hei tinei i te ahi ki runga i te hau.

Nga mea whakamaarama: te kohu wai, te pahuka, te paura maroke, te hauhā, te onepu.

Te maimoatanga tuku ohorere

Te maimoatanga ohorere

Wewetehia te waahi pokea me te aukati i te urunga. Tapahia te puna ahi. E taunaki ana kia mau nga kaimahi ohotata ki te whakamarumaru puehu (te kanohi kanohi katoa) me nga kakahu whakamarumaru. Horoi ki te wai nui, waimeha ki te wai horoi ka maka ki te punaha wai para. Mena he nui te rerenga, kohia hei hangarua, kawea atu ranei ki te waahi tuunga para hei tuku.

Tikanga rokiroki

Kiia i roto i te peeke raranga me te peeke kirihou o roto, e 5 nga paparanga peeke pepa kraft kikii.Me hiri te waha o te peeke kia kaua e turuturu.Ko te taumaha kupenga 25±0.2kg mo ia peeke.
