Kugwiritsa ntchito
Phthalein ndi wapakatikati wa fungicide phenoxy ester.Amagwiritsidwanso ntchito ngati wapakatikati wa mankhwala abwino.Amagwiritsidwa ntchito popanga utoto wapakati 1,4-dichloroanthraquinone, 1- chloroanthraquinone, anticoagulant phenylindandione, bactericide tetrachlorophthalide, ndi anxiolytic mankhwala.Amagwiritsidwanso ntchito ngati organic synthesis wapakatikati, popanga mankhwala a doxepin ndi utoto wocheperako wa bulauni BR, ndi zina zambiri.

[Kumeza] Ngati wovulalayo ali maso komanso watcheru, perekani makapu 2-4 a mkaka kapena madzi.Osapereka chakudya kwa munthu amene ali chikomokere.Pezani thandizo lachipatala.
[Kukoka mpweya] Nthawi yomweyo kuchokera pamalowo kupita ku mpweya wabwino.Ngati palibe kupuma, perekani mpweya wochita kupanga.Ngati kupuma kuli kovuta, perekani mpweya wa okosijeni.Pezani chithandizo chamankhwala.
[Khungu] Pezani chithandizo chamankhwala.Osachepera mphindi 15 mukutsuka khungu ndi sopo wambiri ndi madzi, chotsani zovala ndi nsapato zoipitsidwa.Zovala ziyenera kutsukidwa musanagwiritsenso ntchito.
[Maso] Yambani ndi madzi ambiri kwa mphindi zosachepera 15, tsukani maso, ndi kukweza zikope zakumtunda ndi zapansi nthawi ndi nthawi.Pitani kuchipatala msanga.

【Chogwirira】 Sambani bwino mukatha ntchito.Chotsani zovala zomwe zawonongeka ndikuzichapa musanagwiritse ntchito.Gwiritsani ntchito mpweya wokwanira.Chepetsani kupanga fumbi ndi kuchulukana.Pewani kukhudza maso, khungu ndi zovala.Sungani chidebe kuti musatseke mpweya.Pewani kuyamwa ndi kupuma.
Chidziwitso changozi
[Kumeza] Kungayambitse kuyabwa kwa m'mimba.The toxicological katundu wa chinthu ichi sanafufuzidwe mokwanira.
[Kukoka mpweya] Kungayambitse kupsa mtima kwa thirakiti la kupuma.The toxicological katundu wa chinthu ichi sanafufuzidwe mokwanira.
[Khungu] Zingayambitse kuyabwa pakhungu.
【Maso】 Akhoza kukhumudwitsa maso.
Kuwongolera / Kutetezedwa kwaumwini
Chitetezo Pawekha】Maso: Valani zovala zodzitchinjiriza zodzitchinjiriza kapena magalasi otetezedwa ndi mankhwala, diso la OSHA ndi malamulo oteteza kumaso 29 CFR 1910.133 kapena European Standard EN166.Khungu: Valani magolovesi oteteza kuti musakhudze khungu.Zovala: Valani zovala zoyenera zodzitetezera kuti musakhudze khungu.
[Kupumira] Tsatirani malamulo opumira a OSHA 29 CFR 1910.134 kapena European Standard EN 149. Onetsetsani kuti mumagwiritsa ntchito mpweya wovomerezeka wa NIOSH kapena European Standard EN 149 pakufunika.
Njira zozimitsa moto.
[Kuzimitsa Moto] Zida zodzitetezera zokha, MSHA / NIOSH (kapena zofanana), ndi zovala zotetezera thupi lonse zimafunika kuvala pansi pa kukakamizidwa.Pakayaka moto, mpweya wokwiyitsa komanso wowopsa kwambiri ukhoza kupangidwa ndi kuwola kapena kuyaka.Zimitsani ndi kupopera madzi amoto, ufa wowuma wa mankhwala, mpweya woipa, kapena thovu loyenera.
Njira zothandizira kutaya mwangozi
[Kutayikira kwakung'ono/kudontha] Yeretsani nthawi yomweyo pogwiritsa ntchito zida zoyenera zodzitetezera.Tsukani kapena kuyamwa zinthuzo ndikuzitaya mu chidebe choyera, chowuma, chopanda mpweya.Pewani kupanga zinthu zafumbi.Perekani mpweya wabwino.
