Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Nemhaka yenzvimbo yaro huru yepamusoro uye huwandu hwehuwandu hwehydrogen gasi, yakaoma, yakashandiswa Raney nickel inonzi pyrophoric zvinhu zvinoda kushandiswa pasi pemhepo isina simba. Raney nickel inowanzopiwa se50% slurry mumvura. Kunyange pashure pokuita, Raney nickel inosara ine huwandu hwakakura hwehydrogen gasi uye inogona kupisa nokukurumidza kana ichibudiswa kumhepo. Uyezve, kusvibiswa kwakanyanya kuRaney nickel kunogona kukonzera kutsamwa kwemapapu uye mhino dzemhino, uye kunokonzera pulmonary fibrosis kana ikafemerwa. Kunwa kunogona kutungamirira kukudedera uye zvirwere zvomudumbu. Inogonawo kuita kuti maziso uye ganda zvigumbuke. Kuratidzwa kwenguva refu kunogona kutungamirira ku pneumonitis uye zvimwe zviratidzo zvekuziva nickel, zvakadai semakumbo eganda (" nickel itch ").  Mubvunzo: Chii chinonzi bundu rinokonzerwa nokuva nomutobvu?
