Keeb kwm ntawm qhov project
Pharmaceutical Manufacturing Industry yog hais txog cov txheej txheem uas cov khoom siv raw ua cov khoom siv tshuaj tshiab tom qab lub cev lossis tshuaj hloov pauv, suav nrog kev tsim tshuaj suav thiab Western tshuaj, cov tshuaj kws kho tsiaj kuj suav nrog cov khoom siv tshuaj thiab cov khoom siv kho mob. Kev lag luam kws tshuaj thiab kws tshuaj yog kev lag luam tshuaj lom neeg uas muaj cov txheej txheem cumbersome thiab cov txheej txheem nyuaj. Flammable tshuaj feem ntau yog tsim. Cov khoom siv hluav taws xob no tshwj xeeb yog xa mus rau cov pa tawg uas tsim los tom qab sib xyaw nrog huab cua, uas tej zaum yuav yog cov pa roj, cov kua roj tsw qab, cov pa hluav taws xob, thiab lwm yam. Cov pa phem tseem ceeb uas feem ntau tshwm sim hauv cov txheej txheem tshuaj yog: ammonia, chlorine, formaldehyde, sulfur. dioxide, hydrogen sulfide, oxygen, VOCS, ozone, cov kuab tshuaj, thiab lwm yam.
roj txaus ntshai
Kev muaj peev xwm ntawm methanol (CH3OH), ethanol (C2H6O), tag nrho cov organic tebchaw tsis muaj zog (TVOC) thiab lwm cov pa roj hauv cov chaw ua haujlwm, cov chaw soj nstuam thiab cov tsev khaws khoom ntawm cov chaw muag tshuaj loj. Methanol muaj toxicity tsawg rau tib neeg lub cev, thiab muaj tshuaj loog rau hauv nruab nrab paj hlwb; nws muaj kev xaiv tshwj xeeb ntawm cov paj hlwb thiab retina, ua rau mob; Nws tuaj yeem ua rau metabolic acidosis. Ethanol yog cov tshuaj toxicity tsawg, volatile, thiab yog lub hauv paus paj hlwb kev nyuaj siab. Lub sij hawm ntev raug rau siab concentration ntawm cov khoom no tuaj yeem ua rau khaus ntawm lub qhov ntswg, qhov muag, thiab cov mucous daim nyias nyias, nrog rau mob taub hau, kiv taub hau, qaug zog, chim siab, tshee, xeev siab, thiab lwm yam. Ua rau ntev ntev ntawm daim tawv nqaij tuaj yeem ua rau khaus. . Ua rau dryness, scaling, chapping thiab dermatitis. TVOC tuaj yeem ua rau lub cev tsis muaj zog tiv thaiv kab mob, cuam tshuam rau kev ua haujlwm ntawm lub paj hlwb hauv nruab nrab, thiab ua rau kiv taub hau, mob taub hau, tsaug zog, qaug zog, hauv siab nruj thiab lwm yam kev mob tshwm sim; Nws kuj tseem tuaj yeem cuam tshuam rau lub plab zom mov, xws li tsis qab los noj mov, xeev siab, thiab lwm yam. Thaum mob hnyav, nws tuaj yeem ua rau lub siab thiab hematopoietic system. Kev tsis haum tshuaj, thiab lwm yam.
Raws li cov kev cai cuam tshuam hauv National Standard: "Occupational Exposure Limits for Hazardous Factors in the Workplace", methanol: PC-TWA: 25mg/m3 (17.5ppm), PC-STEL: 50mg/m3 ( 35 ppm); ethanol: PC-TWA, 1900mg / m3 (911ppm), PC-STEL 2400mg / m3 (1151ppm); TVOC: PC-TWA 0.60mg/m3, PC-STEL no; PC-TWA: 8h hnub ua hauj lwm thiab 40h ua hauj lwm lub lis piam teev los ntawm lub sij hawm raws li qhov hnyav qhov nruab nrab tso cai raug concentration.
Cov txheej txheem txheej txheem
Txhawm rau tiv thaiv kev nyab xeeb ntawm ib puag ncig hauv cheeb tsam ntawm lub Hoobkas, yuav tsum tau teeb tsa lub tshuab hluav taws xob tshuaj lom neeg los xyuas lub sijhawm ua haujlwm ntawm cov chaw ua haujlwm, chaw soj nstuam, warehouses, thiab lwm yam. Thaum qee cov ntsiab lus roj ntau tshaj li tus qauv, kev ntsuas raws sijhawm yuav tsum tau ua. coj kom tsis txhob muaj kev phom sij.
