Cov Ntaub Ntawv Kev Nyab Xeeb

p-Terphenyl is a flammable solid that may release toxic fumes when burned. Its acute toxicity is low, with an oral LD₅₀>10, {{000 mg / kg rau cov nas, tab sis kev kis tau ntev yuav ua rau lub siab thiab raum puas. Raws li GHS kev faib tawm, cov tshuaj no yog qhov tsis tshua muaj kev lom zem rau dej yug tsiaj (theem kev lom zem theem 1, H400) thiab yuav tsum zam kev nkag mus hauv cov dej ntim dej. Hnav tsom iav tiv thaiv, hnab looj tes, thiab ib tus neeg ua pa, thiab lub sijhawm ua haujlwm kom tiv thaiv kom tsis txhob muaj kev tiv thaiv tawv nqaij.
