Phosphine yog xim tsis muaj xim, muaj kuab lom nrog qej- zoo li tsw. Nws yog feem ntau tsim los ntawm decomposition ntawm phosphides xws li txhuas phosphide thiab zinc phosphide. Kev nqus pa los yog kev sib cuag tuaj yeem ua rau muaj kev puas tsuaj rau ntau lub cev, nrog rau cov pa thiab cov hlab ntsha.
1. Kev tiv thaiv kev lag luam / kev ua liaj ua teb
Fumigation qhov chaw yuav tsum yog airtight. Ua ntej siv, xyuas qhov tseeb ntawm cov khoom siv npog. Cov nplej nplej yuav tsum tau muab kaw kom nruj. Thaum sealing, npog cov nplej nrog cov yas zaj duab xis thiab nias cov npoo kom ruaj khov. Lub sij hawm sealing yuav tsum tau txwv rau kwv yees li 10 hnub.
Thaum siv aluminium phosphide fumigation, cov neeg ua haujlwm yuav tsum hnav lub npog ntsej muag roj (lub kaus poom yuav tsum tau kuaj xyuas kom zoo), cov khaub ncaws tiv thaiv, thiab hnab looj tes roj hmab. Yog tias pom muaj ntxhiab tsw ntxhiab thaum ua haujlwm, khiav tawm tam sim ntawd.
Cov chaw ua haujlwm yuav tsum tau nruab nrog cov khoom siv hluav taws xobphosphine nteslos yog kho cov kev soj ntsuam hauv online los saib xyuas cov tshuaj phosphine hauv lub sijhawm tiag tiag kom ntseeg tau tias lawv nyob qis dua qhov kev nyab xeeb ntawm 0.3 mg / m³ (kwv yees li 0.2 ppm). Qhov cua kub ceev yuav tsum tau pib tam sim yog tias qhov concentration siab tshaj qhov kev nyab xeeb.
Fumigation yuav tsum ua kom tiav tsawg kawg yog xya hnub, thiab warehouses yuav tsum tau rov qab - tsuas yog tom qab cov concentration poob qis dua 0.2 ppm.
2. Kev ceev faj hauv tsev thiab niaj hnub
Aluminium phosphide yuav tsum muab cia rau hauv qhov chaw kaw, qhuav, thiab qhov cua. Nws yuav tsum tsis txhob sib xyaw nrog cov khoom siv hauv tsev thiab yuav tsum khaws cia kom deb ntawm cov menyuam yaus.
Thaum lub tsev fumigation, thaj chaw ua haujlwm yuav tsum tau muab cais tawm ntawm thaj chaw nyob kom tsis txhob muaj cov neeg ua haujlwm nyob hauv qhov chaw kaw.
Khaws qhov chaw ua haujlwm kom qhuav kom tsis txhob muaj phosphine deliquescing nrog dej los tsim phosphine.
3. Cov ntsiab lus teb rau xwm txheej ceev
Cov tib neeg raug kev nqus pa lom yuav tsum tau tsiv mus rau qhov chaw muaj cua, tshem tawm cov khaub ncaws tsis huv, thiab yaug nrog dej huv li 15 feeb yog tias raug rau ntawm daim tawv nqaij. Yog hais tias muaj tshuaj lom xws li txhuas phosphide tau raug yuam kom noj, tsis txhob ua rau ntuav lossis siv magnesium sulfate ua cathartic. Tam sim ntawd ua lub plab lavage nrog 1: 5000 poov tshuaj permanganate tov thiab muab activated charcoal ntawm qhov ncauj kom nqus tau cov tshuaj lom.
Cov neeg mob uas muaj mob me me mus rau qhov hnyav hnyav yuav tsum tau kho cov pa oxygen sai (-paj pa oxygen lossis hyperbaric oxygen chamber) thiab kev ntxuav cov ntshav, ntxiv nrog cov tshuaj xws li glucocorticoids thiab diuretics los tswj cov tsos mob.
4. Kev tiv thaiv cov neeg tshwj xeeb
Cov menyuam yaus yuav tsum tau khaws cia kom deb ntawm qhov chaw fumigation thiab chaw khaws tshuaj tua kab, thiab yuav tsum tau qhia kom tsis txhob kov cov khoom uas muaj phosphides, xws li cov ntais ntawv thiab cov tshuaj tua kab mob.
Thaum tua hluav taws los ntawm phosphine, tsuas yog npog qhov hluav taws kub nrog xuab zeb; tsis txhob siv dej. Cov zaub mov fumigated hauv tsev yuav tsum tau ua kom huv si kom tshem tawm cov tshuaj lom ua ntej ua thiab noj.Qhov kev pheej hmoo ntawm phosphine lom tuaj yeem txo tau zoo los ntawm cov txheej txheem kev ua haujlwm, txhim kho cov cuab yeej tiv thaiv, phosphine detector yog ib qho tiag tiag -lub sij hawm concentration xyuas cov cuab yeej uas tuaj yeem ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm.
