1,4-dimethoxybenzene yog feem ntau suav tias muaj tsawg toxicity, tab sis nws txoj kev nyab xeeb nyob ntawm ib puag ncig uas nws siv thiab qib kev sib kis. Ntawm no yog qee cov ntsiab lus tseem ceeb txog nws kev nyab xeeb:
1. Toxicity: Nws tsis yog tshuaj lom, tab sis kev sib cuag siab siab yuav ua rau muaj kev rau tawv nqaij, ob lub qhov muag, thiab ua pa.
2. Kev tuav: nrog rau ntau yam tshuaj lom neeg, nws raug pom zoo tias 1,4-dimethoxybenzene raug daws tau cov khoom siv zoo (PPE) xws li hnab looj tes thiab gobgles.
3. Inhalation thiab kev noj haus: Tsis txhob nqus tau pa lossis cov kev haus cawv uas yog qhov no yuav ua rau muaj kev noj qab haus huv zoo.
4. Ib puag ncig cuam tshuam: Nws yog ib qho tseem ceeb los xav txog nws qhov cuam tshuam rau ib puag ncig thiab ua raws li cov lus qhia kom tsim nyog.
