Badbaadada iyo isticmaalka 2,4-dibromopyridine waa in lagu ilaaliyaa si waafaqsan qodobbada soo socda:

- Xaruntani waa sun waana in si taxadar leh loo maareeyaa.

- Qalabka ilaalinta shakhsi ahaaneed ee habboon sida galoofyada, muraayadaha, iyo dharka ilaalinta waa in la gashado inta lagu guda jiro wax ka qabashada iyo isticmaalka.

- Iska ilaali inaad boodhkeeda neefsato ama maqaarka iyo indhaha la taabto.

- Waa in lagu qalaa meel hawo fiican leh, lagana fogaado in la taabto il dab ah si aanu dab u qabsan ama u qarxin.

- Nidaamyada qalliinka ee saxda ah ee badbaadada leh waa in la raaco inta lagu jiro maaraynta iyo kaydinta.
