Chitetezo cha poizoni
Kukwiya pang'ono pakhungu, koma osayamwa.Chifukwa cha kuchepa kwa mphamvu ya nthunzi, chiopsezo cha mpweya umodzi chimakhala chochepa kwambiri.Komabe, mavuto aakulu angayambitse kukanika kwa chapakati mantha dongosolo, kuchititsa matenda a kupuma ziwalo, impso ndi mtima dongosolo.Mbewa zinakoka mpweya wa mankhwalawa kwa maola awiri pamlingo wa 0.18 ~ 0.20mg/L, zomwe zingayambitse kupsa mtima pang'ono kumtunda kwa kupuma ndi m'maso.LD50 ya mbewa ndi makoswe inali 5200 mg / kg ndi 7900mg / kg motsatira.Pazipita zololeka ndende pa ntchito ndi 100mg/m3.Ogwiritsa ntchito pamalowo ayenera kuvala masks, magalasi oteteza ndi magolovesi.
Kupaka, kusungirako ndi kunyamula Chida ichi sichimagwiritsidwa ntchito ndi mankhwala ndipo sichiwononga zitsulo zina monga carbon steel ndi aluminiyamu kupatula mkuwa.Imapakidwa m’ng’oma zachitsulo zokhala ndi malata, 50kg kapena 100kg pa ng’oma, ndipo timaphukusi ting’onoting’ono timapakidwa m’mabotolo agalasi kuti tipewe kuwala.Sungani ndi kunyamula molingana ndi malamulo a mankhwala.
