I want to ask, before the flux, solder paste and red glue unopened, in the fridge, and food can be put together? Is there any harm to the human body?
Whether it is a lead-free solder and lead solder paste, many have some heavy metals with other trace elements inside, if long-term with food were placed in the refrigerator, is certainly not good, suggest you apart will be safe point.
Can not! Occasionally one or two times, the time is not long, it will not hurt the body!
Must not, and very unhappy
