4-Bromo-3-fluorotoluene ndi mankhwala oopsa ndipo sayenera kukhudzana mwachindunji ndi khungu, maso, ndi kupuma. Mukagwiritsidwa ntchito, muyenera kuvala zida zoyenera zodzitetezera monga magolovesi, magalasi, ndi chishango choteteza kumaso. Pogwira ntchitoyi, njira zoyendetsera chitetezo cha labotale ziyenera kutsatiridwa ndikugwiritsidwa ntchito pamalo abwino kwambiri. Iyenera kusungidwa pamalo owuma, ozizira komanso opanda mpweya wabwino, kutali ndi magwero a moto ndi malawi otseguka. Opaleshoni iliyonse yogwiritsira ntchito pawiri iyenera kuchitidwa ndi zida zoyenera ndi mikhalidwe, ndi maphunziro oyenerera ndi ogwira ntchito omwe amamvetsetsa bwino ntchito.
