Deta ya poizoni
Kuopsa kwa poizoni:

LD50 yomwa: 783mg/kg (nkhumba ya Guinea)

800 mg/kg(m'mimba)

832 mg/kg (makoswe)

Zotsatira zazikulu zokwiya:

Pakhungu: Zimakwiyitsa khungu ndi ma mucous nembanemba.

Pamwamba pa maso: zotsatira za kukwiya.

Kuzindikira: Palibe zotsatira zodziwika bwino za kuzindikira.

Deta ya zachilengedwe
Cholembera cha bulangeti

Kuopsa kwa madzi mulingo 1 (malamulo aku Germany) (kudziyesa nokha kudzera pamndandanda) Chinthu ichi ndi choopsa pang'ono ku madzi.

Musalole kuti zinthu zosasungunuka kapena zambiri zikhudze madzi apansi pa nthaka, njira zamadzi kapena njira zotayira zinyalala.

Musatulutse zinthu m'malo ozungulira popanda chilolezo cha boma.

Chilengedwe ndi kukhazikika
Ndi poizoni pang'ono, zimakwiyitsa khungu ndi ma mucous nembanemba. Jakisoni wa pansi pa khungu la makoswe LD50:376mg/kg. Zipangizo zoyankhira ziyenera kukhala zopanda mpweya, ndipo choyankhira cha carboxylation chiyenera kukwaniritsa miyezo ya kuthamanga. Ogwira ntchito ayenera kuvala zophimba nkhope zoteteza ndi zida zina zoteteza, ndikusunga mpweya wabwino m'malo ogwirira ntchito.

Njira yosungira
Chogulitsachi chiyenera kutsekedwa ndi kusungidwa kutali ndi kuwala.

Gwiritsani ntchito
Zopaka utoto. Zimagwiritsidwa ntchito popanga Naphthol AS ndi mitundu ina ya Naphthol, monga Naphthol AS-BO, AS-RL, AS-E, AS-D, AS-VL, AS-BS, AS-OL, ndi zina zotero. Zingagwiritsidwenso ntchito popanga Light Fast Brilliant Red BBC, Light Fast Red BBN, Rubber Red LG, Pigment Brilliant Red 6B, Lithol Red BK. Zimagwiritsidwanso ntchito ngati mankhwala ophatikizana.
Pambuyo poti β-naphthol ndi sodium hydroxide zipanga mchere, kutentha ndi kumasula madzi m'thupi zimachepa, ndipo mchere wa β-naphthol womwe umapezeka umasungunuka ndi carbon dioxide kuti upange mchere wa 2,3 acid disodium, womwe umasungunuka ndi sulfuric acid kuti ukhale womalizidwa.
