Kev nyab xeeb

qhov toxicity tsawg heev, thiab kev nco qab sai dua tom qab lom, yog li nws tuaj yeem siv los ua tshuaj loog. Irritant rau daim tawv nqaij thiab mucous membrane. Cov neeg laus nas tsuag qhov ncauj ld501.6ml/kg. Qhov siab tshaj plaws tso cai nyob rau hauv huab cua yog 500 × 10-6. Kev ua haujlwm yuav tsum hnav lub npog ntsej muag roj, pom tam sim tom qab muaj tshuaj lom los ntawm qhov chaw, cov tsos mob kho nrog galvanized hlau nruas kaw ntim, 250kg ib chim, tsheb ciav hlau tank tsheb, tsheb thauj mus los. Yuav tsum tau muab cia rau hauv qhov chaw txias tsaus, qhov chaw zoo-ventilated, them sai sai rau cov dej noo.
