Final answer:
Using a repaired polystyrene bottle holder in the fridge should not pose any health and safety risks.
Step-by-step explanation:
The use of butyl acetate glue to repair the polystyrene bottle holder in your fridge should not pose any health and safety risks. Once the glue has dried and the repairs are complete, the polystyrene and butyl acetate should not be releasing any harmful chemicals or odors.
It is important to note that the primary concern with polystyrene is the possibility of Bisphenol A (BPA) leaching into food or drinks. However, since there is no direct contact between the repaired bottle holder and unpackaged food, the potential for BPA exposure is minimal.
