Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Pyridine inokuvadza kana ikafemerwa, yakamedzwa kana kuti yakapinda muganda. Migumisiro yokurumwa kwakakomba ne pyridine inosanganisira dzungu, kutemwa nomusoro, kusawirirana, kusvotwa, kubuda kwemuromo, uye kurasikirwa nechido chokudya. Dzinogona kupfuurira kuva kurwadziwa kwomudumbu, kuvharika kwemapapu uye kusaziva. Mumwe munhu akafa pashure pokunge adya hafu yekapu yepyridine. Nhamba yakaderera inozivikanwa inouraya (LDLo) yokunwa kwe pyridine muvanhu i500 mg·kg−1. Mumirimo mikuru, pyridine ine simba rinodhaka uye mwando wayo wevhu unopfuura 3600 ppm unopa ngozi kuutano. LD50 yomumuromo mumakonzo ndeye 891 mg·kg−1. Pyridine inopisa.  Mubvunzo: Chii chiri chidukusa icho munhu anogona kutora chepyridine kuti chigare chichiuraya?
