Say pangan na dakel et nayarin manresulta ed saray sintomas a singa say pan-ugip, pansuka, tan pan-eek. No grabe so kaso, nayarin pansengegan itan na metabolic acidosis, sakey a kondisyon ya say laman et mantitipon na dakel ya asido. Say pakakontak ed baog na concentrated propylene glycol et nayarin pansengegan na iritasyon ed arum ya indibidual, lalo la ed saramay sensitibo so baog da. Nepeg ya paliisan so andukey odino paulit-ulit ya pakapatnagan na baog. No usaren ed industriyal iran pasen, nakaukolan so suston bentilasyon pian ag nasingap so singaw na propylene glycol, ta say atagey a lebel na singaw et nayarin pansengegan na ag-inkakomportable ed panag-ingas.

Peligro na Poolan tan Insabog: Say propylene glycol et mainomay ya napoolan, anggaman medyo atagey so flash point to. Saray singaw to et nayarin manporma na makapasabog iran laok ed dagem diad pigaran kondisyon. Saray pasen a panagsimpenan tan panag-asikasoan et nepeg ya arawian ed apoy, saray silew, tan arum niran lapuan na apoy. Saray ag napoolan ya panagsimpenan tan matukoy iran kagawaan ya ag napoolan et nepeg ya walad saray lugar ya pangisimpenan o panguusaran na propylene glycol.
Epekto ed Kaliberliber: Bangta say propylene glycol et nabulok, say baleg ya pangibulos ed kaliberliber, lalo la ed saray danum, et nayarin walay epekto to. Diad saray sistema na danum, nayarin mangupot na oxygen legan ya nabubulok, ya nayarin mangapekta ed saray bilay ed danum. Kanian, nepeg ya walay suston panangasikaso tan panangipuera ed basura pian naprebentaan so agnakontrol ya itatagey na propylene glycol ed kaliberliber.
