Sei Phosgene Gas Scrubbing Ichifanira Kuitwa?
Kukwesha negasi rePhosgeneZvakakosha nekuda kwezvikonzero zvakawanda:
Kuchengetedzeka:Kusangana nePhosgene pahuwandu hwakaderera se3–5 ppm kunogona kukonzera kutsamwa kwekufema, nepo huwandu hwakakwira huchikonzera kuzvimba kwemapapu. Kukwesha kunodzivirira kusangana nevashandi nenharaunda.
Kutevedzera Mutemo:Mitemo yakaoma, yakaita seyeEPA, inorayira kuti pave nekutarisa nekudzora kuburitswa kwe phosgene kuchengetedza nharaunda.
Kudzivirirwa Kwezvakatipoteredza:Kuburitswa kwephosgene kusingadzoreki kunogona kusvibisa mhepo nemvura, zvichikanganisa nharaunda.
